STM32MP235A

概要

STM32MP23xA/D devices are based on the high-performance single or dual-core Arm® Cortex®-A35 64-bit RISC core operating at up to 1.5 GHz. The Cortex®‑A35 processor includes a 32-Kbyte L1 instruction cache for each CPU, a 32-Kbyte L1 data cache for each CPU, and a 512-Kbyte L2 cache. The Cortex®‑A35 processor uses a highly efficient 8-stage in-order pipeline that has been extensively optimized to provide full Armv8-A features while maximizing area and power efficiency.

STM32MP23xA/D devices also embed a Cortex®-M33 32-bit RISC core operating at up to 400 MHz frequency. The Cortex®-M33 core features a floating point unit (FPU) single precision which supports Arm® single-precision data-processing instructions, and data types. The Cortex®-M33 supports a full set of DSP instructions, TrustZone®, and a memory protection unit (MPU) which enhances application security.

STM32MP23xA/D devices can also embed a 3D graphic processing unit (VeriSilicon®, OpenGL ES 3.1, Vulkan 1.3, OpenCL 3.0, OpenVX 1.3) running at up to 400 MHz, with performances up to 66.5 Mtriangle/s, 400 Mpixel/s.

The graphic processing unit can provide a neural processor unit (VeriSilicon®, TensorFlowLite, ONNX, Linux NN) running at up to 400 MHz.

STM32MP23xA/D devices provide an external SDRAM interface supporting external memories up to 32‑Gbit density (4 Gbytes), 16-bit DDR3L up to 1066 MHz, 16-bit LPDDR4 or DDR4 up to 1200 MHz.

The devices incorporate high-speed embedded memories: 776 Kbytes of internal SRAM (including 256-Kbyte AXI SYSRAM, 128-Kbyte AXI video SRAM (which can be used as general purpose), two banks of 128 Kbytes each of AHB SRAM, 128 Kbytes of AHB SRAM in backup domain, and 8 Kbytes of SRAM in backup domain), as well as an extensive range of enhanced I/Os and peripherals connected to APB buses, AHB buses, a 32-bit multi-AHB bus matrix, and a 128/64-bit multi-layer AXI interconnect supporting access to internal and external memories.

Each device offers three ADCs, a low-power secure RTC, 12 general-purpose 16-bit timers, 4 general-purpose 32‑bit timers, two PWM timers for motor control, five low-power timers, and a true random number generator (RNG).

STM32MP23xA/D devices offer a video decoder.

The devices support 4 multi-function digital filters.
