The STM32F427/437 lines offer the performance of the Cortex-M4 core (with floating point unit) running at 180 MHz while reaching lower static power consumption (Stop mode) versus STM32F405/415/407/F417.
Performance: At 180 MHz, the STM32F427/437 deliver 225 DMIPS/608 CoreMark performance executing from Flash memory, with 0-wait states thanks to ST’s ART Accelerator. The DSP instructions and the floating point unit enlarge the range of addressable applications.
Power efficiency: ST’s 90 nm process, ART Accelerator and the dynamic power scaling enables the current consumption in run mode and executing from Flash memory to be as low as 260 µA/MHz at 180 MHz. In Stop mode, the power consumption is 120 µA typical, which is 3 times lower versus the STM32F405/415/407/F417.
Graphics: As opposed to the STM32F429/439, the STM32F427/437 does not embed an LCD-TFT controller interface. However, it is possible to connect a display to the parallel or serial interfaces and still take full advantage of ST’s Chrom-ART Accelerator™ graphics accelerator performing content creation twice as fast as the core alone. This graphics accelerator supports efficient 2-D raw data copy, as well as image blending or image format conversion (mixing and transparency). As a result, the Chrom-ART Accelerator boosts graphics content creation and saves processing bandwidth of the MCU core for the rest of the application.
Integration :
- Audio: 2 dedicated audio PLL, 2 full duplex I²S and a new serial audio interface (SAI) supporting time division multiplex (TDM) mode
- Up to 20 communication interfaces (including 4x USARTs plus 4x UARTs running at up to 11.25 Mbit/s, 6x SPI running at up to 45 Mbit/s, 3x I²C with a new optional digital filter capability, 2x CAN, SDIO)
- Analog: two 12-bit DACs, three 12-bit ADCs reaching 2.4 MSPS or 7.2 MSPS in interleaved mode
Up to 17 timers: 16- and 32-bit running at up to 180 MHz - Easily extendable memory range using the flexible 90 MHz memory controller with a 32-bit parallel interface, and supporting Compact Flash, SRAM, PSRAM, NOR, NAND and SDRAM memories
- Analog true random number generator
- The STM32F437 also integrates a crypto/hash processor providing hardware acceleration for AES-128, -192 and -256, with support for GCM, CCM, Triple DES, and hash (MD5, SHA-1 and SHA-2)
The STM32F427 and F437 product lines provide from 1-Mbyte dual-bank Flash to 2-Mbyte dual-bank Flash, 256-Kbyte SRAM and from 100 to 176 pins in packages as small as 7 x 7 mm. With such memory integration, the need for external memory is reduced, allowing smaller, safer and low-emission PCB designs.
精选 视频
As part of our embedded online event, we had the pleasure of filming with Reinhard Keil, a Senior Director of Embedded Tools at ARM.
This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course. This is our first STM32 based on Cortex-M33 and its Trustzone and using specific ST security implementation - watch the video to find out more!
The STM32L5 is based on Arm® Cortex-M33 and TrustZone® technology combined with STMicroelectronics security implementation. On your STM32L562E-DK discovery board, TrustZone is disabled (factory setting) and you can develop as on any other STM32 device. This video shows how to enable TrustZone on STM32L562E-DK discovery using STM32CubeProgrammer and create, compile and debug or run a new project with STM32CubeIDE. It also shows how to open an example project delivered in STM32CubeL5 MCU Package, modify, compile and debug or run it. For further information, you can refer to AN5394 and AN5424 application notes.
