Description  
AT89S53  
The AT89S53 is a low-power, 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 nonvolatile memory programmer.  
By combining a versatile 8-bit CPU with Downloadable Flash on a monolithic chip, the  
Atmel AT89S53 is a powerful microcomputer which provides a highly flexible and cost  
effective solution to many embedded control applications.  
The AT89S53 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 AT89S53 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.
