Product details
Overview
STM32F722IEK6 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 21 communication interfaces - deployed in industrial HMI, motor control gateways, and embedded audio processing systems.
For engineers reviewing the STM32F722IEK6 datasheet, STM32F722IEK6 pinout, STM32F722IEK6 application, or STM32F722IEK6 equivalent, key selection criteria include Cortex-M7 real-time performance (L1 cache + ART Accelerator), dual USB OTG support (HS/FS with dedicated DMA), triple-interleaved ADC throughput (7.2 MSPS), and 140 I/Os with 5 V tolerance - critical for mixed-signal edge controllers requiring deterministic latency and peripheral concurrency.
Technical Context
The STM32F722IEK6 implements an adaptive real-time accelerator (ART) with 8 KB instruction and 8 KB data caches, 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, on-chip FS/HS PHY, and ULPI option - supporting simultaneous host/device roles. The bxCAN 2.0B interface operates independently of USB timing, while the flexible memory controller (FMC) supports NOR/NAND/SDRAM with up to 32-bit data bus width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-M7 with FPU, 216 MHz max, 462 DMIPS - enables real-time DSP, motor control, and protocol stack offload without external co-processors. |
| Flash Memory | 512 KB with PCROP and read/write protection - supports secure firmware updates and IP protection in field-deployed devices. |
| SRAM | 256 KB data TCM + 16 KB instruction TCM + 4 KB backup SRAM - isolates critical control loops and retains RTC/calendar state during power loss. |
| ADC Performance | 3×12-bit, 2.4 MSPS each; 7.2 MSPS in triple interleaved mode - sufficient for simultaneous sampling of multi-axis current/voltage sensors in servo drives. |
| USB Interfaces | OTG_FS (on-chip FS PHY) + OTG_HS (dedicated DMA, on-chip FS/HS PHY or ULPI) - allows concurrent USB device HID + host mass storage operation without CPU overhead. |
| I/O Count & Tolerance | Up to 140 I/Os; 138 pins 5 V-tolerant - simplifies level-shifting in legacy industrial backplanes and mixed-voltage sensor networks. |
| Timers | 18 timers including 2×32-bit general-purpose and 13×16-bit (1 low-power in Stop mode) - supports complex PWM generation, encoder counting, and precise time-stamping across multiple axes. |
Pinout & Package
LQFP64 (10 × 10 mm, 0.5 mm pitch) package with exposed thermal pad; 64-pin quad flat configuration optimized for compact industrial control modules and cost-sensitive HMI designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD, VSS | Core & I/O supply rails | Separate 1.7–3.6 V domains enable independent power sequencing and noise isolation between analog/digital sections. |
| VCAP1, VCAP2 | Internal LDO decoupling | Requires 2.2 µF ceramic capacitors per pin - mandatory for stable 1.2 V core voltage regulation at 216 MHz operation. |
| PA0–PA15, PB0–PB15, etc. | General-purpose I/Os | 138 pins 5 V-tolerant; all support EXTI, most configurable as AF for USART/SPI/I2C/SAI - enables direct connection to RS-485 transceivers and audio codecs. |
| USB_OTG_FS_DP/DM, USB_OTG_HS_ULPI_ DIR/CLK/Dx | USB physical layer interfaces | Dual-stack support: FS uses internal PHY; HS uses either internal dual PHY or external ULPI PHY - provides layout flexibility for EMI-constrained enclosures. |
| ADC1_IN0–ADC1_IN15, etc. | Analog input channels | 24-channel routing across 3 ADCs; supports hardware oversampling and injected conversion sequences - essential for synchronized current sensing in 3-phase inverters. |
Key Features
| Feature | Design Value |
|---|---|
| ART Accelerator + L1 Cache | Eliminates Flash wait states at 216 MHz, delivering deterministic interrupt latency (<1 µs) for closed-loop motor control. |
| Dual USB OTG Controllers | Enables simultaneous USB device (e.g., CDC ACM virtual COM port) and host (e.g., USB flash drive file access) operation without software arbitration. |
| Triple-Interleaved ADC Mode | 7.2 MSPS aggregate sampling rate across 3 ADCs with synchronized triggers - captures transient fault waveforms in power electronics protection circuits. |
| Flexible Memory Controller (FMC) | Supports external SDRAM for GUI frame buffers and NAND for firmware logging - extends local memory beyond on-chip SRAM limits. |
| True Random Number Generator (RNG) | Meets NIST SP800-90A requirements for cryptographic key generation in secure boot and TLS handshake implementations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F767ZIT6 | Higher Flash (2 MB) and SRAM (512+128+4 KB); adds Ethernet MAC, FMC with SDRAM support, and additional SAI/Quad-SPI - but larger LQFP144 package. | Required for applications needing Ethernet connectivity or >512 KB code space (e.g., Linux-capable edge nodes). | Select when Ethernet, larger memory, or advanced audio interfaces outweigh cost and board area constraints. |
| STM32H743VIT6 | Dual-core (Cortex-M7 + Cortex-M4), higher clock (480 MHz), enhanced security (AES/HASH/CRYP), and larger TCM (1 MB total) - but no native USB HS PHY (ULPI only). | Suitable for asymmetric multiprocessing (e.g., M7 for control, M4 for comms) and certified secure boot in medical/industrial safety systems. | Choose for functional safety (IEC 61508 SIL3-ready) or dual-core workload partitioning where USB HS PHY is not mandatory. |
Compared with STM32F767ZIT6, the STM32F722IEK6 offers identical Cortex-M7 performance and USB HS capability in a smaller LQFP64 footprint, while the STM32H743VIT6 trades integrated USB HS PHY for dual-core flexibility and hardened crypto - making the F722IEK6 optimal for compact, USB-centric real-time controllers.
