The AT89C4051-24PU is a low-voltage, high-performance CMOS 8-bit microcontroller based on the industry-standard MCS-51 architecture. It integrates 4 Kbytes of on-chip Flash program memory with 10,000 write/erase cycles, 128 bytes of internal RAM, 15 programmable I/O lines, two 16-bit timer/counters, a full-duplex UART serial port, and an on-chip analog comparator. The device supports two low-power modes — Idle and Power-down — and includes brown-out detection and power-on reset (POR).
Operating from a supply voltage of 4V to 6V and fully static up to 24 MHz, the AT89C4051 is designed for robust embedded control applications. It features an internal oscillator and can drive LEDs directly. The 20-pin PDIP (0.300") through-hole package simplifies prototyping and is suitable for industrial temperature ranges from -40°C to +85°C.
This microcontroller is compliant with RoHS, REACH, and is lead-free and halogen-free, meeting modern environmental standards. Its versatile peripheral set and Flash endurance make it a cost-effective choice for applications requiring reprogrammability and reliable operation in harsh environments.
The supply voltage range is 4V to 6V.
It is available in a 20-pin PDIP (0.300", 7.62mm) through-hole package.
It operates from -40°C to +85°C (TA).
Yes, it is RoHS compliant, lead-free, and halogen-free per the datasheet.
It uses an 8051 8-bit core.
It has 4KB of Flash program memory (4K x 8) with 10,000 write/erase cycles.
The maximum clock frequency is 24 MHz.
