Description

The AT89C1051 is a low-voltage, high-performance CMOS 8-bit microcomputer with

1K byte of Flash programmable and erasable read only memory (PEROM). The

device is manufactured using Atmel’s high density nonvolatile memory technology

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

a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C1051 is a pow-

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

many embedded control applications.

The AT89C1051 provides the following standard features: 1K Byte of Flash, 64 bytes

of RAM, 15 I/O lines, one 16-bit timer/counter, a three vector two-level interrupt archi-

tecture, a precision analog comparator, on-chip oscillator and clock circuitry. In addi-

tion, the AT89C1051 is designed with static logic for operation 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 con-

tinue functioning. The Power Down Mode saves the RAM contents but freezes the

oscillator disabling all other chip functions until the next hardware reset.
