1. Description

AT89C2051-12PI is a low-voltage, high-performance CMOS 8-bit microcomputer with 2K bytes of Flash programmable and erasable read-only memory (PEROM). This The device is manufactured using Atmel's high-density non-volatile storage technology And compatible with the industry standard MCS-51 instruction set. By combining one Atmel AT89C2051-12PI is a powerful microcomputer with powerful functions. It is a powerful microcomputer with a powerful microcomputer that can provide solutions for many applications. Embedded control application. AT89C2051-12PI provides the following standard functions: 2K bytes of flash memory, 128 RAM bytes, 15 I/O lines, two 16-bit timers/counters and a five-vector two-level interrupt Architecture, full-duplex serial port, precision analog comparator, on-chip oscillator And clock circuit. In addition, AT89C2051-12PI has a static logic design, can run at low to zero frequency, and supports two software-selectable energy-saving methods mode. Idle mode stops the CPU, while allowing RAM, timer/counter, serial The port and interrupt system continue to operate. Power-down mode save RAM content, but freeze the oscillator, disable all other chip functions until the next Hardware reset
