製品概要

概要

The STM32C53xxx devices are general purpose microcontrollers family (STM32C5 series) based on the high‑performance Arm^® Cortex^®-M33 32-bit RISC core. They operate at a frequency of up to 144 MHz.

The Cortex^®-M33 core features a single‑precision floating‑point unit (FPU) that supports all the Arm^® single‑precision data‑processing instructions and all the data types.

The Cortex^®-M33 core also implements a full set of digital signal processing (DSP) instructions and a memory protection unit (MPU) that enhances the application security.

The devices embed high‑speed memories (up to 256‑Kbyte flash memory and 64‑Kbyte SRAM), and an extensive range of enhanced I/Os, peripherals connected to three APB buses, three AHB buses, and a 32‑bit multi‑AHB bus matrix.

The devices feature several protection mechanisms for embedded flash memory and SRAM: readout protection, write protection, and hide protection areas.

The devices embed several peripherals reinforcing security:

HASH hardware accelerator
True random number generator

The devices offer one 12‑bit ADC, two DAC channels, two comparators, one operational amplifier, a low‑power RTC, one 32‑bit general‑purpose timer, two 16‑bit PWM timers dedicated to motor control, two 16‑bit general‑purpose timers, two 16‑bit basic timers, and one 16‑bit low‑power timer.

The devices also feature standard and advanced communication interfaces such as:

One I2C
One I3C
Two SPIs with muxed full-duplex I2S
Two USARTs, two UARTs, and one low‑power UART
Two FDCANs
One USB full‑speed

The devices operate in the -40 to +105 °C (+140 °C junction) temperature ranges from a 2.7 to 3.6 V power supply.

A comprehensive set of power‑saving modes allows the design of low‑power applications.

The devices offer multiple packages from 20 to 64 pins.
