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.
