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.
