Overview

Description

ST72F321BJ9T6 is an 8-bit microcontroller from STMicroelectronics, part of the ST72/ST72F3xx family. It targets cost-sensitive embedded control tasks requiring on‑chip memory and peripherals.
Key, high-level features:
- On-chip Flash program memory and RAM for data
- Peripherals such as timers/PWM, ADC/analog comparators, and common serial interfaces (USART/UART, SPI, I2C)
- Wake-up capability and low-power modes for energy-efficient operation
- Flexible clock options (internal oscillator and external clock input)
- In-system programming and debugging support with ST tools
Typical applications include automotive, consumer electronics, and industrial control where a compact, budget-friendly MCU is advantageous. Exact details—memory sizes, pin count, package options, operating voltage, temperature range, and peripheral set—vary by revision.
For precise specs and development guidance, consult the official STMicroelectronics datasheet and user manual for ST72F321BJ9T6.
