STMicroelectronics STM32F358RCT6

Overview

STM32F358RCT6 from STMicroelectronics is an ARM® Cortex®-M4 32-bit MCU with FPU, operating up to 72 MHz, featuring 256 KB Flash, 48 KB SRAM (including 40 KB user SRAM + 8 KB CCM), four 12-bit ADCs (38-channel, 0.2 µs conversion), two 12-bit DACs, seven rail-to-rail comparators, and four programmable-gain operational amplifiers - deployed in industrial motor control and precision analog signal conditioning systems.

For engineers reviewing the STM32F358RCT6 datasheet, STM32F358RCT6 pinout, STM32F358RCT6 application, or STM32F358RCT6 equivalent, key selection considerations include its integrated analog front-end (PGA + COMP + DAC + ADC), CAN 2.0B interface, 1.8 V core supply tolerance, and LQFP64 package compatibility with high-density mixed-signal embedded designs.

Technical Context

The STM32F358RCT6 integrates a Cortex-M4 core with hardware floating-point unit and memory protection unit (MPU), enabling deterministic real-time execution of DSP-intensive control algorithms. Its interconnect matrix decouples peripheral bus arbitration, supporting concurrent high-bandwidth transfers between ADCs, DACs, timers, and DMA channels without CPU intervention.

Analog subsystem coherency is maintained via independent voltage domains: VDDA (1.65–3.6 V) for ADC/DAC/COMP, VOPAMP (2.4–3.6 V) for op-amps, and dedicated VREFINT and temperature sensor calibration-enabling simultaneous multi-channel precision acquisition and closed-loop analog processing within a single die.

FAQ

What is the maximum operating frequency and core voltage specification for STM32F358RCT6?

The STM32F358RCT6 operates at up to 72 MHz using the Cortex-M4 core with FPU. Its core supply (VDD) is specified at 1.8 V ±8%, meaning it functions reliably from 1.656 V to 1.944 V. This tight voltage tolerance enables low-power operation while maintaining deterministic timing for real-time control loops.

Does STM32F358RCT6 support hardware CRC calculation and memory protection?

Yes - it includes a dedicated CRC calculation unit compliant with IEEE 32-bit polynomial (0x04C11DB7) for firmware integrity checks and data packet validation. It also features a Memory Protection Unit (MPU) with eight configurable memory regions, enabling privilege-level enforcement between application code, bootloader, and interrupt service routines.

How many analog peripherals are integrated, and what are their key electrical constraints?

The device integrates four 12-bit ADCs (38 total channels, 0.2 µs conversion), two 12-bit DACs (2.4–3.6 V analog supply), seven rail-to-rail comparators (1.65–3.6 V), and four op-amps usable as PGAs (gain 1–16). All analog peripherals require separate VDDA/VSSA filtering, and DAC outputs need external buffering for loads <10 kΩ or >100 pF.

Is STM32F358RCT6 pin-compatible with other STM32F3 packages, and what debug interfaces does it support?

No - the STM32F358RCT6 uses LQFP64 (64-pin) packaging and is not pin-compatible with LQFP48 or LQFP100 variants of the same family. It supports Serial Wire Debug (SWD) and JTAG via dedicated SWCLK/SWDIO and TCK/TMS/TDO/TDI pins, with full ETM trace capability for real-time instruction flow analysis during development.
