STMicroelectronics STM32F722RCT6

Overview

STM32F722RCT6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller with FPU, operating at up to 216 MHz (462 DMIPS), featuring 512 KB Flash, 256+16+4 KB SRAM, USB OTG HS/FS, three 12-bit ADCs (2.4 MSPS), two 12-bit DACs, and 18 timers - deployed in industrial HMI, motor control gateways, and real-time audio processing systems.

For engineers reviewing the STM32F722RCT6 datasheet, STM32F722RCT6 pinout, STM32F722RCT6 application, or STM32F722RCT6 equivalent, key selection criteria include Cortex-M7 real-time performance, dual USB OTG support (HS + FS), TCM RAM allocation for deterministic latency, and 140 I/Os with 5 V tolerance - critical for mixed-voltage industrial edge nodes.

Technical Context

The STM32F722RCT6 implements an adaptive real-time accelerator (ART Accelerator) with 8 KB instruction and 8 KB data L1 cache, enabling zero-wait-state execution from Flash and external memories. Its memory subsystem includes 256 KB data TCM RAM (for time-critical variables), 16 KB instruction TCM RAM (for latency-sensitive routines), and 4 KB backup SRAM retained in Standby mode with VBAT.

It integrates dual USB OTG controllers: one full-speed with on-chip PHY, and one high-speed/full-speed with dedicated DMA and dual PHY support (on-chip HS/FS or ULPI). The peripheral set includes two SAIs for stereo audio I²S/TDM, three ADCs supporting triple interleaved mode (7.2 MSPS aggregate), and a flexible external memory controller supporting SDRAM, NOR, and NAND.

FAQ

What is the maximum operating frequency and associated DMIPS rating?

The STM32F722RCT6 operates at up to 216 MHz with a measured 462 DMIPS (Dhrystone 2.1), achieved via the Cortex-M7 core with FPU and ART Accelerator. This performance level is sustained across voltage ranges (1.7–3.6 V) and ambient temperatures (–40°C to +105°C), as verified in DS11853 Rev 9 Section 6.3.1.

Does this MCU support USB High-Speed device mode without an external PHY?

Yes - the STM32F722RCT6 integrates a dedicated USB OTG HS controller with on-chip high-speed PHY, enabling native USB 2.0 high-speed (480 Mbps) device or host operation without external components. This is confirmed in Section 2.12 of DS11853 Rev 9 and distinguishes it from variants requiring ULPI.

How much SRAM is allocated to TCM and what is its functional purpose?

The device provides 256 KB of data TCM RAM and 16 KB of instruction TCM RAM. Data TCM hosts time-critical buffers (e.g., ADC samples, PWM registers); instruction TCM stores latency-sensitive ISRs and control algorithms - both guarantee single-cycle access independent of cache misses or bus arbitration delays.

Which packages are available for the STM32F722xx series, and which one corresponds to the 'R' in STM32F722RCT6?

The 'R' in STM32F722RCT6 denotes the LQFP64 package (10 × 10 mm), as specified in Table 1 and Section 7.1 of DS11853 Rev 9. Other package options include LQFP100, LQFP144, LQFP176, UFBGA144, UFBGA176, and WLCSP100 - all sharing identical peripheral sets but differing in I/O count and thermal performance.
