Preliminary

Description

The AT89C4051 is a low-voltage, high-performance CMOS 8-bit microcomputer with

4K Bytes of Flash programmable and erasable read only memory (PEROM). The

device is manufactured using Atmel鈥檚 high density nonvolatile memory technology

and is compatible with the industry standard MCS-51鈩?instruction set. By combining

a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C4051 is a pow-

erful microcomputer which provides a highly flexible and cost effective solution to

many embedded control applications.

The AT89C4051 provides the following standard features: 4K Bytes of Flash, 128

bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt

architecture, a full duplex serial port, a precision analog comparator, on-chip oscillator

and clock circuitry. In addition, the AT89C4051 is designed with static logic for opera-

tion down to zero frequency and supports two software-selectable power saving

modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial

port and interrupt system to continue functioning. The Power Down Mode saves the

RAM contents but freezes the oscillator disabling all other chip functions until the next

hardware reset.
