216 MHz Cortex-M7 — flash wait-state budget at boot
The STM32F722RET6 is an STMicroelectronics 32-bit ARM Cortex-M7 MCU from the STM32F7 series. The 64-LQFP package (10×10 mm) exposes 50 I/O, plus a rich peripheral set: CANbus, I²C, SPI, UART/USART, USB OTG, QSPI, SAI, and IrDA.
512 KB Flash / 256 KB SRAM — firmware and data buffer sizing
The 512 KB Flash (512K x 8) accommodates moderate-complexity firmware images — RTOS, TCP/IP stack, USB device stack, and application code fit without external memory in many designs. The 256 KB SRAM (256K x 8) provides headroom for double-buffered ADC data, display frame buffers, or a second-stage bootloader. If your application exceeds 512 KB of code, the STM32F722ZE (512 KB Flash, 144-pin) or STM32F723 (1 MB Flash) are the next density steps in the same family.
