Developer news

We are pleased to announce the release of TouchGFX 4.25.0, a significant update packed with new core functionalities and numerous bug fixes to enhance your development experience. Here’s a glimpse of what’s new:LTDC-driven display: emulated framebufferThis major feature introduces memory savings by using the MCU’s memory instead of external RAM. By allocating memory for only a subregion of the display and synchronizing between the LCD controller and graphics framework, full screen storage is unnecessary. This is ideal for static UIs but may require adjustments for animations to avoid screen tearing. Check out the blog article and the dedicated page in our documentation. Bitmap font compressionTouchGFX 4.25.0 introduces bitmap font compression, which can drastically reduce flash usage for applications with extensive font usage. You can enable 4Bpp bitmap font compression in the Designer under the Typography tab in the “Text” menu and configure the “Compressed Font Cache Size” in the Text Configuration Tab in the “Config” menu. Translations in external unmapped flashBuilding on our support for translations in external mapped flash, this version extends support to unmapped flash. Translations are copied into RAM for mapping. Enable this by checking “Copy translations to RAM” in the Text Configuration Tab in the “Config” menu. Improved designer performanceTouchGFX Designer now operates efficiently without a persistent internet connection, making it usable even in remote locations. Additionally, project opening and creation times have been significantly reduced, even for large projects. Simplified importing of custom containersImporting custom containers is now streamlined. If conflicts arise during import, you can select specific files to import, allowing updates to existing containers or the use of pre-existing assets. Configurable partial framebuffer block sizeYou can now configure the block dimension of your partial framebuffer, crucial for project setup. CMake supportTouchGFX now supports CMake projects. Detailed setup, build, and debug instructions are available in our documentation.Enhanced rotated display features: this will address the requests in the forum here and here.Two new features for rotated displays:Single smart framebuffer mode: now supported, resolving previous coordinate reference issues.

ST’s DCP3601 miniature monolithic buck converter combines extensive feature integration and flexibility, enabling simple, low-BOM designs to achieve high conversion efficiency. The power switches and compensation are built-in, requiring only six components to complete the circuit, including the inductor, bootstrap and filter capacitors, and feedback resistors for setting the output voltage. With its 3.3V-to-36V input voltage range and 1A output capability, the DCP3601 can power low-voltage loads in applications such as smart meters, domestic appliances, and industrial 24V conversion. Synchronous rectification and a fixed switching frequency of 1MHz ensure high efficiency across the load range and under all operating conditions, reaching 91% at 600mA with 12V input and 5V output. Flexibility comes from the selection of different variants, offering the choice of forced-PWM operation for noise-sensitive applications or pulse-skipping at light load for minimal power consumption. Additionally, both the low-noise and low-consumption variants are available with frequency dithering to reduce noise power at the 1MHz switching frequency. All variants have extremely low quiescent current of 110µA and an Enable pin that allows turning off the converter with a dedicated signal to maximize power savings. Designers can quickly start new projects with the DCP3601 using the dedicated evaluation board, STEVAL-3601CV1. The board comes with screw terminals and headers and is ready to power-up out of the box, demonstrating an efficient circuit design with a compact footprint. First in the new buck-converter product family that will expand throughout the year, the DCP3601 is included in ST’s 10-year longevity program that ensures long-term access to components and support. Packaged as a 3mm x 1.6mm SOT23 6-lead device, the single-chip buck converter is priced from $0.48 for orders of 1000 pieces. Additional resourcesDiscover the DCP360 series  Datasheet DCP3601 Data brief STEVAL-3601CV1First published on Feb 25, 2025

16g/80g dual-range IMU with edge processing brings advanced sports monitoring to affordable wearables to “train like a pro!”. ST’s innovative LSM6DSV80X combines two accelerometer structures for 16 g and 80 g full-scale sensing, a gyroscope up 4000 dps, and embedded intelligence in a single component. Capable of measuring events ranging from slight movements to intense impacts with equal accuracy, the new sensor enables enhanced features in devices such as wearables and sports trackers. ST’s new MEMS sensor is set to redefine standards and expectations in markets for consumer and specialist wearables. By incorporating the LSM6DSV80X personal electronic devices can provide advanced capabilities such as training analysis and performance benchmarking to help athletes improve their technique. While the low-g accelerometer tracks and identifies activities like walking, running, and gesture-based interactions, high-g measurement handles energetic movements that can saturate conventional IMUs and impair accuracy. With these unique all-in-one capabilities, the LSM6DSV80X has numerous applications in sports equipment, such as monitoring performance while running or jumping. Downhill running and explosive activities like plyometrics can involve impacts over 30 g, placing high stress on knees and ankles that can now be recorded easily and cost effectively. In boxing, where impacts often exceed 60 g, athletes can now capture data using commercially available wearables empowered by LSM6DSV80X to improve strength and power, as well as detecting concussions to increase safety. Sports such as tennis can benefit from intensity impact measurements for insights to improve racquet control and acceleration for greater speed and accuracy. Alongside its advanced accelerometer architecture, the LSM6DSV80X also integrates a MEMS gyroscope and digital processing with sensor fusion low power (SFLP) technology that enables spatial orientation detection and gesture detection. In addition, ST’s machine learning core (MLC) and finite state machine (FSM) provide edge processing in the sensor to boost performance and save power. By processing the raw data locally, the IMU can recognize wearers’ activities autonomously and simplify host communications for sharper responses and lower power consumption. This permits fuller analysis of sports training, checking how accurately the athlete is performing the exercises. The sensor also features adaptive self-calibration (ASC) to adjust for different activity scenarios. Developers can find full support for the LSM6DSV80X in ST MEMS-Studio, the free graphical environment that provides tools for configuring the sensor, training the MLC decision tree, and testing. In addition, ST provides a selection of affordable evaluation boards that can host the new sensor with an adapter board, including the Professional MEMS tool (STEVAL-MKI109D) and SensorTile.box PRO (STEVAL-MKBOXPRO). Samples of the LSM60DSV80X, in a 14-pin 2.5 mm x 3 mm x 0.86 mm LGA package are available now and volume production is scheduled by the end of April 2025. Sample requests and pricing information are available from local ST sales offices. Additional resourcesProduct overview Product presentation Product page LSM6DSV80X Data brief LSM6DSV80X Blog post "LSM6DSV32X and 3 New MEMS That Vastly Improve the Performance-per-Watt Ratio" On-demand webinar "Measure and protect!

With CAN FD on-chip, users can trim the BOM and simplify the hardware design of industrial communication and networking devices, leveraging the upgraded protocol’s flexibility, speed, and payload capacity.  "The STM32C0 series offers great flexibility as a cost-conscious line in the STM32 family, with memory ranging from 32 KByte to 256 KByte of flash and rich peripherals," commented Patrick Aidoune, General Purpose MCU Division General Manager, STMicroelectronics. "The large flash and RAM now available in the STM32C091/C092 let designers host the graphical user interface alongside the main application, leveraging ST’s TouchGFX tools to create entertaining experiences and streamline development." As the most affordable entry point to the STM32 family, STM32C0 MCUs contain widely used interfaces such as crystal-less USB Full Speed Device and USARTs, as well as timers and an analog/digital; converter (ADC). Complementing the cost-conscious feature set, the economical design with on-chip clocks and just one power-supply input saves additional external components including timing and decoupling from the bill of materials (BOM). Further, these savings enable a smaller, simpler PCB design.All STM32C0 MCUs come with extra benefits for developers, including ST’s extended longevity program that ensures long-term availability throughout the lifetime of industrial projects. As members of the high-quality STM32 family, designing with STM32C0 MCUs also eases compliance with product-level approvals such as IEC 61508 for functional safety. The devices contain the Arm® Cortex®-M0+ core that also powers STM32G0 MCUs, which are designed for higher performance and advanced features. The two STM32 MCU series share many aspects including package styles and pinout, and peripheral IP, enabling designs to migrate easily between the two. The latest STM32C0 microcontrollers are in production now, priced from $0.426 for STM32C051F8P6, $0.682 for the STM32C091FCP6, and $0.733 for the STM32C092FCP6 with CAN FD, for orders of 10,000 pieces.Additional resourcesProduct page STM32C0  Blog post "STM32C071: A modern GUI for $5, now possible thanks to 128 KB of flash and 24 KB of RAM!"First published on Feb 19, 2025

ST has revealed a flexible power-management IC for highly integrated processors like Stellar automotive microcontrollers that lets users program the power-up sequence and fine-tune output voltages and current ranges to fulfill system requirements. The SPSB100 can be used throughout vehicles, in zonal control unit (ZCU), vehicle control platform (VCP), body control (BCM), and gateway modules. The SPSB100, with three switched-mode buck converters and two linear voltage regulators (LDOs), supplies the voltage rails required for the system microcontroller and can power external peripheral loads and sensors. Additionally, there are two wake-up inputs and advanced failsafe functionalities. An internal boost controller stabilizes the power during transients such as cold-cranking pulses, start/stop operation, and weak battery conditions. All the SPSB100 buck converters have overcurrent detection and current limiting for safety, with built-in soft start to prevent excessive inrush currents. Two of the converters can deliver up to 3A output current at a selectable output voltage of 3.3V, 5V, or 6.5V. The third converter can deliver up to 6A at 3.3V, 1.25V, 1.2V, 1.1V, or 0.98V. Among the LDOs, one has a fixed 5V output capable of sourcing up to 120mA with 2% accuracy. The second can be configured to track any of the buck converters at 3.3V or 5V. There is also one high-side driver, which provides open-load and over-current diagnostics. Further features include integrated non-volatile memory (NVM) for storing the output-voltage values and power-up sequence. An SPI port allows programming and supports control and diagnostics, allowing designers to use the SPSB100 in many electronic platforms that require different rails and peripherals. The SPSB100 has a deep-sleep mode that draws less than 40µA quiescent current.

ST’ L99MH98 8-channel gate driver brings patented features for building automotive motor drives without sensing resistors, reducing power dissipation and the bill of materials. The L99MH98 can drive four external full bridges, eight half bridges or single high-side/low-side powering mechanisms such as seat-position adjusters, window lifters, sunroofs, pumps, seatbelt pretensioners, and other actuators. The L99MH98 can also drive resistive loads such as heaters, and the internal circuitry contains a charge pump whose output can control a reverse-battery protection MOSFET. While the drivers can control both logic-level and standard-level MOSFETs, extended gate current capability, programmable up to 120mA, permits driving large numbers of external MOSFETs. Three-stage gate control, which applies the gate signal in three steps, helps to minimize electromagnetic emissions. Designed to provide each MOSFET’s drain-source voltage (VDS) to an analog-digital converter (ADC), the L99MH98 leverages indirect current measurement to replace sensing resistors. This ST-patented technique calculates the drain current in each MOSFET by combining the measured VDS with RDS(on) predicted using sensed temperature. The system is calibrated at manufacture to find the nominal RDS(on) values, enabling predictions to be made using the MOSFETs’ resistance-versus-temperature curves. A further feature, also ST-patented, is the programmable multi-failsafe function that enhances reliability by turning off bridges individually to protect against faults while allowing unaffected bridges to operate normally. Multi-failsafe detects faults including supply overvoltage, high-side over/undervoltage, thermal warning, charge-pump failure, VDS-monitoring failure, and selectively turns off functions such as diagnostics, watchdog, and charge pump depending on fault type. The L99MH98 is AEC Q100 qualified and meets ISO 26262 criteria for functional-safety applications up to safety integrity level (ASIL) B. Available now in a VFQFN48L package with wettable flanks and exposed underside cooling pad, the L99MH98 is priced from $2.44 for orders of 1000 pieces. Additional resourcesL99MH98 product overview L99MH98 datasheetFirst published on Nov 27, 2024
