STMicroelectronics have added two new microcontroller lines which increase energy efficiency, flexibility, and feature integration at the high end of the STM32F4 Access Line for high-performance embedded designs. The new STM32F413/423 MCUs are qualified for operating temperature ranges up to -40°C to 125°C. The new MCUs target always-on sensor acquisition and general-purpose industrial applications and present a robust and cost-effective upgrade from STM32F1 MCUs.
STMicroelectronics provide application note (AN4904) to help migrate microcontroller applications from STM32F1 Series to STM32F4 Access lines by providing guidance on hardware compatibility, boot-mode selection and peripheral migration. Click here to download the application note.
The STM32F413 and crypto-enhanced STM32F423 integrate up to 1.5MB Flash and unusually dense SRAM of 320KB. These are the most highly featured of the STM32F4 Access Lines, with rich audio capabilities including a Serial Audio Interface (SAI) and an enhanced voice-acquisition interface with multi-channel Digital Filter for Sigma-Delta Modulators (DFSDM) that enables low-power sound localization and beam forming. The devices also provide superior peripheral integration, with two 12-bit Digital-Analog Converters (DACs), up to 10 UARTs, and three CAN 2.0B Active interfaces. The crypto-enhanced STM32F423 also has a True Random-Number Generator (TRNG) and AES-256 cryptographic hardware accelerator.
Sitting at the top of the STM32F4 Access Lines, the new MCUs introduce a 100MHz dual-mode Quad SPI for connecting serial off-chip memory, 16-bit Flexible Static Memory Controller (FSMC) for external SRAM, PSRAM or NOR Flash, up to 16-bit QVGA or 8-bit WQVGA LCD interface, and USB OTG with Link Power Management (LPM) and dual power rails that save external level shifting.
In addition, both lines feature a new RAM-access scheme that uses the instruction and data (I/D) buses and the system bus (SBUS) to connect to separate RAM1 (256KB) and RAM2 (64KB) areas thereby minimizing contentions. A new, enhanced DMA Batch Acquisition Mode (BAM+) takes advantage of these separate RAM1 and RAM2 areas to process code and data extremely efficiently in sensor-hub applications.
Delivering high performance with best-in-class energy efficiency, the new STM32 microcontrollers combine the 100MHz 125DMIPS/339 EEMBC© CoreMark© ARM© Cortex©-M4 core with ST’s power-saving Dynamic Efficiency technologies that cut RUN mode current to as little as 112µA/MHz. These Dynamic Efficiency technologies include the ST ART Accelerator™ for zero-wait execution from Flash, and the supply-voltage extending down to 1.7V, to maximize the battery life of always-connected devices.
The STM32F413 and STM32F423 are available in seven package options from 4.039mm x 3.951mm WLCSP81 to 144-pin LQFP.
