STMicroelectronics STM32F358CCT6

Overview

STM32F358CCT6 from STMicroelectronics is an ARM® Cortex®-M4 32-bit microcontroller with FPU, operating at up to 72 MHz, featuring 256 KB Flash, 48 KB SRAM (including 40 KB user SRAM + 8 KB CCM), four 12-bit ADCs (0.20 µs conversion), two 12-bit DACs, seven rail-to-rail comparators, and four programmable-gain operational amplifiers - deployed in industrial motor control, analog signal conditioning, and precision sensor interface systems.

For engineers reviewing the STM32F358CCT6 datasheet, STM32F358CCT6 pinout, STM32F358CCT6 application, or STM32F358CCT6 equivalent, key selection considerations include its integrated analog front-end (4 PGA, 7 COMP, dual DAC), CAN 2.0B interface, 86 fast I/Os (several 5 V-tolerant), and support for capacitive touch sensing across 24 channels - all within LQFP64 package constraints.

Technical Context

The STM32F358CCT6 integrates a Cortex-M4 core with hardware floating-point unit and memory protection unit (MPU), enabling deterministic real-time execution of DSP-intensive tasks such as motor FOC or digital power control. Its interconnect matrix decouples peripheral bus arbitration from CPU timing, allowing concurrent high-bandwidth transfers via 12-channel DMA without CPU intervention.

Analog subsystem coherency is maintained through independent voltage domains: VDDA (1.65–3.6 V) powers ADCs, DACs, comparators, and op-amps; VREFINT and VOPAMP provide stable internal references; and dedicated CCM SRAM (8 KB) with hardware parity supports time-critical interrupt handlers and control loop buffers.

FAQ

What is the maximum operating frequency and core type of the STM32F358CCT6?

The STM32F358CCT6 features an ARM Cortex-M4 core with integrated FPU, rated for a maximum clock frequency of 72 MHz. It achieves 90 DMIPS (Dhrystone MIPS) from Core Coupled Memory and supports single-cycle multiplication and hardware division - enabling efficient execution of control algorithms and DSP operations without external coprocessors.

Does the STM32F358CCT6 support hardware-based capacitive touch sensing?

Yes, it integrates a dedicated Touch Sensing Controller (TSC) supporting up to 24 capacitive sensing channels. This hardware accelerator handles electrode scanning, noise filtering, and baseline tracking autonomously, enabling robust touchkey, linear slider, and rotary encoder implementations without consuming CPU cycles or requiring external touch ICs.

What are the analog supply voltage requirements for the ADC, DAC, and op-amps?

The ADCs require VDDA in the range 1.65–3.6 V; DACs and op-amps operate from 2.4–3.6 V analog supply; comparators function from 1.65–3.6 V. These separate voltage domains allow optimized noise isolation - for example, powering VDDA from a low-noise LDO while running digital logic from a switching regulator.

Is the STM32F358CCT6 pin-compatible with other STM32F3-series MCUs in LQFP64?

No - while sharing the LQFP64 package outline, STM32F358CCT6 has a unique pin assignment optimized for its analog feature set (e.g., dedicated DAC outputs on PA4/PA5, PGA terminals on PB0/PB1/PC0–PC5). Pin compatibility is limited to same-part variants (e.g., STM32F358CCU6 in QFN48), not cross-family members like STM32F303 or STM32F334.
