Description  
The AT89C2051 is a low-voltage, high-performance CMOS 8-bit microcomputer with  
2K Bytes of Flash programmable and erasable read only memory (PEROM). The  
device is manufactured using Atmel’s high density nonvolatile memory technology  
and is compatible with the industry standard MCS-51™ instruction set. By combining  
a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C2051 is a pow-  
erful microcomputer which provides a highly flexible and cost effective solution to  
many embedded control applications.  
AT89C2051  
The AT89C2051 provides the following standard features: 2K Bytes of Flash, 128  
bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt  
architecture, a full duplex serial port, a precision analog comparator, on-chip oscillator  
and clock circuitry. In addition, the AT89C2051 is designed with static logic for opera-  
tion 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  
hardware reset.
