The AT89C4051-24PU is a low-voltage, high-performance 8-bit microcontroller from Atmel’s 8051 series, optimized for cost-effective embedded control applications. Designed with 4K bytes of reprogrammable Flash memory, this microcontroller provides flexibility for firmware updates and prototyping.
With 128 bytes of RAM, a full-duplex serial UART, and an integrated precision analog comparator, the AT89C4051 is an excellent choice for sensor-based applications, serial communication, and real-time control systems. The 24MHz operating frequency ensures fast instruction execution, making it suitable for demanding embedded tasks.
The AT89C4051 is designed with multiple low-power operating modes, including Idle Mode (which keeps peripherals running while stopping the CPU) and Power-Down Mode (which retains RAM data while shutting down the oscillator), making it ideal for battery-powered applications.
Encased in a DIP-20 package, this microcontroller is easy to integrate into prototyping, DIY electronics, industrial control, and consumer electronics projects.
