STMicroelectronics STM32F413/423 MCUs

The STM32F413 and crypto-enhanced STM32F423 microcontroller lines from STMicroelectronics are said to increase energy efficiency and flexibility. They feature integration at the high end of the STM32F4 Access Line for high-performance embedded designs.

Qualified up to 125°C, the devices target always-on sensor acquisition and general-purpose industrial applications and present an upgrade from STM32F1 MCUs. They integrate up to 1.5 MB Flash and dense SRAM of 320 KB.

The products feature rich audio capabilities including a Serial Audio Interface (SAI) and an enhanced voice-acquisition interface with multichannel digital filter for sigma-delta modulators (DFSDM) that enables low-power sound localisation and beam forming. The devices also provide good peripheral integration, with two 12-bit digital-analog converters (DACs), up to 10 UARTs and three CAN 2.0B Active interfaces. The STM32F423 also has a true random-number generator (TRNG) and AES-256 cryptographic hardware accelerator.

The MCUs introduce a 100 MHz dual-mode Quad SPI for connecting serial off-chip memory, a 16-bit flexible memory controller (FMC) 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.

Both lines feature a RAM-access scheme that uses the instruction and data (I/D) buses and the system bus (SBUS) to connect to separate RAM1 (256 KB) and RAM2 (64 KB) areas, thereby minimising contentions. An enhanced DMA batch acquisition mode (BAM+) takes advantage of these separate areas to process code and data efficiently in sensor-hub applications.
