1. Description

The AT89LS51 is a low-voltage, high-performance CMOS 8-bit microcontroller with

4K bytes of in-system programmable Flash memory. The device is manufactured

using Atmel’s high-density nonvolatile memory technology and is compatible with the

industry-standard 80C51 instruction set and pinout. The on-chip Flash allows the pro-

gram memory to be reprogrammed in-system or by a conventional nonvolatile

memory programmer. By combining a versatile 8-bit CPU with in-system programma-

ble Flash on a monolithic chip, the Atmel AT89LS51 is a powerful microcontroller

which provides a highly-flexible and cost-effective solution to many embedded control

applications.

AT89LS51

The AT89LS51 provides the following standard features: 4K bytes of Flash, 128 bytes

of RAM, 32 I/O lines, Watchdog timer, two data pointers, two 16-bit timer/counters, a

five-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator,

and clock circuitry. In addition, the AT89LS51 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

external interrupt or hardware reset.
