Description  
The AT89C55WD is a low-power, high-performance CMOS 8-bit microcontroller with  
20K bytes of Flash programmable read only memory and 256 bytes of RAM. The  
device is manufactured using Atmel’s high-density nonvolatile memory technology and  
is compatible with the industry standard 80C51 and 80C52 instruction set and pinout.  
The on-chip Flash allows the program memory to be user programmed by a conven-  
tional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash  
on a monolithic chip, the Atmel AT89C55WD is a powerful microcomputer which pro-  
vides a highly flexible and cost effective solution to many embedded control  
applications.  
AT89C55WD  
The AT89C55WD provides the following standard features: 20K bytes of Flash, 256  
bytes of RAM, 32 I/O lines, 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 AT89C55WD 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 con-  
tinue 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.
