AT89LS8252

Description

The AT89LS8252 is a low-power, wide-voltage range, high-performance CMOS 8-bit

microcomputer with 8K bytes of Downloadable Flash programmable and erasable

read only memory and 2K bytes of EEPROM. The device is manufactured using

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

try 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 nonvolatile memory programmer. By combining a ver-

satile 8-bit CPU with Downloadable Flash on a monolithic chip, the Atmel

AT89LS8252 is a powerful microcomputer which provides a highly flexible and cost

effective solution to many embedded control applications.

The AT89LS8252 provides the following standard features: 8K bytes of Downloadable

Flash, 2K bytes of EEPROM, 256 bytes of RAM, 32 I/O lines, programmable watch-

dog timer, two Data Pointers, three 16-bit timer/counters, a six-vector two-level inter-

rupt architecture, a full duplex serial port, on-chip oscillator, and clock circuitry. In

addition, the AT89LS8252 is designed with static logic for operation down to zero fre-

quency and supports two software selectable power saving modes. The Idle Mode

stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt sys-

tem 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 hard-

ware 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.
