Description

AT89LS53

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. The on-chip downloadable Flash allows the program memory to be

reprogrammed in-system through an SPI serial interface or by a conventional nonvol-

atile memory programmer. 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 appli-

cations.

Not Recommended

for New Designs.

Use AT89S8253.

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 Point-

ers, 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 soft-

ware 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 interrupt or hardware reset.

The downloadable Flash can be changed a single byte at a time and is accessible

through the SPI serial interface. Holding RESET active forces the SPI bus into a serial

programming interface and allows the program memory to be written to or read from

unless Lock Bit 2 has been activated.
