AT89S8252  
Description  
The AT89S8252 is a low-power, high-performance CMOS 8-bit microcontroller 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 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 AT89S8252 is a powerful microcontroller, which  
provides a highly-flexible and cost-effective solution to many embedded control  
applications.  
Not Recommended  
for New Designs.  
Use AT89S8253.  
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 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 AT89S8252 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. The Power-down mode saves the RAM contents but freezes the oscillator,  
disabling all other chip functions until the next external 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 bits have been activated.
