ST72F324J4B5 8-Bit Microcontroller IC 8MHz 16KB FLASH
The ST72F324J4B5 is a high-reliability 8-bit microcontroller (MCU) manufactured by STMicroelectronics, belonging to the ST7 series and designed for versatile embedded control applications. Housed in a 42-pin SPDIP through-hole package (36.83×13.72×3.81mm), it operates over a commercial temperature range of -10°C to +85°C, supporting a supply voltage range of 3.8V to 5.5V for stable performance in various power systems. Equipped with an ST7 core running at a maximum 8MHz clock speed, it features 16KB (16K×8) of in-system programmable Flash program memory, 512 bytes of SRAM, 32 programmable I/O pins, and is RoHS-compliant, offered in tube packaging for low-volume assembly and prototyping, with a maximum power dissipation of 500mW.
This MCU integrates a rich set of peripherals and protection features to enhance versatility and reliability. It includes a 10-bit analog-to-digital converter (ADC) with 12 available channels for precise sensor interfacing, two timers for timing and PWM control, and serial communication interfaces (SCI and SPI) for seamless connectivity with external devices. Additional features include low-voltage detection (LVD), power-on reset (POR), watchdog timer (WDT), and internal oscillator, eliminating the need for external components and simplifying system design. Its 8-bit architecture with optimized instruction set ensures efficient processing, while the through-hole package enables easy soldering and maintenance, making it suitable for both industrial and consumer applications.
