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.
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.
