AT89C4051 - 8 bit Microcontroller

AT89C4051 8-bit Microcontroller with 4KB Flash Memory

The AT89C4051 is a high-performance, low-power 8-bit microcontroller based on the MCS-51 instruction set. It features 4KB of in-system reprogrammable Flash memory, allowing for flexible program storage and updates. With 128 bytes of internal RAM and 15 programmable I/O lines, it offers robust capabilities for various embedded applications. This versatile IC operates across a wide voltage range of 2.7V to 6V and supports fully static operation from 0 Hz up to 24 MHz. Integrated peripherals include two 16-bit timer/counters, a programmable serial UART channel, and an on-chip analog comparator. Its low-power idle and power-down modes make it suitable for energy-efficient designs. The AT89C4051 comes in a convenient 20-pin DIP package, ideal for prototyping and production.
