Program memory is 512 KB of Flash, backed by 64 KB of SRAM — enough for a field-oriented motor control stack plus a communication protocol layer. ## Analog front-end and connectivity — 16-channel ADC, DAC, CANbus, USB For system communication it carries CANbus, I²C, SPI, UART/USART, USB, and IrDA interfaces, plus an I²S audio bus. The 51 general-purpose I/O pins give enough headroom for a sensor array with a parallel LCD or keypad matrix. For dual-sourcing or a pin-compatible drop-in with less Flash, the STM32F302R8 (64 KB Flash variant) shares the same footprint and peripheral set.","metaTitle":"STM32F302RET6 STM32F3 ARM Cortex-M4 MCU, 72MHz, 512KB Flash","metaDescription":"STM32F302RET6 32-bit ARM Cortex-M4 MCU in 64-LQFP. 72MHz core, 512KB Flash, 64KB SRAM, 16x12b ADC, CANbus, USB.
