AT89S8252

Description

The AT89S8252 is a low-power, 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 nonvol-

atile memory technology and is compatible with the industry standard 80C51 instruc-

tion 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 non-

volatile memory programmer. By combining a versatile 8-bit CPU with Downloadable

Flash on a monolithic chip, the Atmel AT89S8252 is a powerful microcomputer which

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

cations.

The AT89S8252 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 AT89S8252 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.
