Description

The AT89C1051U is a low-voltage, high-performance CMOS 8-bit microcomputer with

1K byte of Flash programmable and erasable read only memory. It has the same func-

tionality and operation as the AT89C1051 with the addition of a UART programmable

serial port. 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

AT89C1051U is a powerful microcomputer which provides a highly-flexible and cost-

effective solution to many embedded control applications.

AT89C1051U

The AT89C1051U provides the following standard features: 1K byte of Flash, 64 bytes

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

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

clock circuitry. In addition, the AT89C1051U 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 continue functioning. The power-down mode saves the RAM con-

tents but freezes the oscillator disabling all other chip functions until the next hardware

reset.
