The AT89LS53 is a low-power, wide-voltage range, high-performance CMOS 8-bit microcomputer with 12K bytes of downloadable Flash programmable and erasable read only 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.

By combining a versatile 8-bit CPU with downloadable Flash on a monolithic chip, the Atmel AT89LS53 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications.

The AT89LS53 provides the following standard features: 12K bytes of downloadable Flash, 256 bytes of RAM, 32 I/O lines, programmable watchdog timer, two Data Pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and clock circuitry.

In addition, the AT89LS53 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.
