The 512 KB Flash program memory (512K x 8) gives firmware headroom for complex application stacks, communication protocol stacks, and bootloader partitions — enough for a field-upgradeable design with over-the-air update capability. The 64K x 8 RAM supports moderate data buffering for CANopen or Modbus telemetry and real-time control variables. The 115 I/O lines in a 144-LQFP package (20x20 mm) provide ample pin-multiplexing flexibility for sensor arrays, display interfaces, and parallel actuator control. The 18-channel 12-bit ADC and single 12-bit DAC (A/D 18x12b; D/A 1x12b) cover multi-axis analog feedback and setpoint generation without external converters. Connectivity includes CANbus, I²C, SPI, UART/USART, USB, and LINbus — suitable for industrial fieldbus gateways, motor drive comms, and multi-protocol edge nodes. ## Industrial temperature grade: -40 to 85°C Supply range is 2 V to 3.6 V. Internal oscillator reduces external BOM count. For BOM freeze or long-term supply planning, this part remains a viable production choice — no imminent last-time-buy window. ## Date-code and provenance checkpoints","metaTitle":"ST STM32F302ZET6 ARM Cortex-M4 MCU, 72 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32F302ZET6 32-bit MCU with ARM Cortex-M4 core at 72 MHz, 512 KB Flash, 64K x 8 RAM, 115 I/O, 144-LQFP.
