STMicroelectronics STM32F722ZET7TR

Overview

STM32F722ZET7TR 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, dual USB OTG (FS/HS), three 12-bit ADCs (2.4 MSPS), two 12-bit DACs, and CAN 2.0B - deployed in industrial motor control systems requiring real-time deterministic response and multi-interface connectivity.

For engineers reviewing the STM32F722ZET7TR datasheet, STM32F722ZET7TR pinout, STM32F722ZET7TR application, or STM32F722ZET7TR equivalent, key selection considerations include LQFP144 package compatibility, 216 MHz real-time execution with ART Accelerator and L1 cache, triple-interleaved ADC throughput (7.2 MSPS), USB HS/FS dual-role capability, and CAN 2.0B integration for embedded automation networks.

Technical Context

The STM32F722ZET7TR implements an Arm Cortex-M7 core with tightly coupled memory (TCM) architecture: 64 KB data TCM RAM for time-critical variables and 16 KB instruction TCM RAM for latency-sensitive routines, enabling zero-wait-state execution. Its adaptive real-time accelerator (ART) supports full-speed operation from Flash with L1 instruction/data caches (8 KB each).

It integrates dual USB OTG controllers - one full-speed with on-chip PHY, one high-speed with dedicated DMA and dual PHY support (on-chip FS + HS or ULPI) - alongside a flexible external memory controller (FMC) supporting SDRAM, NOR/NAND, and PSRAM, plus dual-mode Quad-SPI for XIP-capable serial flash expansion.

FAQ

What is the maximum operating temperature rating for STM32F722ZET7TR?

The STM32F722ZET7TR is rated for industrial temperature range: −40°C to +105°C ambient, verified per DS11853 Rev 9 Section 6.3.1. This rating applies to the LQFP144 package under specified thermal conditions (θ_JA = 30.5°C/W, PCB with 2 oz copper and 4 thermal vias). No derating is required up to 105°C when meeting recommended PCB layout guidelines.

Does STM32F722ZET7TR support external SDRAM, and what interface does it use?

Yes, the STM32F722ZET7TR supports external SDRAM via its Flexible Memory Controller (FMC) with 16-bit data bus, address lines A0–A12, and control signals (SDCKE, SDCLK, SDSR, SDWE, SDNE). It complies with JEDEC Standard No. 21-C for SDR SDRAM and supports up to 256 MB density, validated in ST reference designs like the STM32756G-EVAL board.

Can the STM32F722ZET7TR operate in low-power modes while maintaining CAN bus activity?

No - CAN peripheral is disabled in Stop and Standby modes. However, the low-power timer (LPTIM1) remains active in Stop mode and can wake the system to re-enable CAN for periodic message transmission. For continuous CAN listen-only operation, the device must remain in Run or Sleep mode, where CAN clock domain stays powered and message filtering continues.

Is the STM32F722ZET7TR pin-compatible with other STM32F722xx variants in LQFP144 package?

Yes - all STM32F722xx devices in LQFP144 (e.g., STM32F722RET6, STM32F722VET6) share identical pinout and electrical characteristics per DS11853 Rev 9 Table 10 and Section 2.1. Differences are limited to Flash/RAM size and feature enablement (e.g., USB HS PHY presence), not pin function or placement.
