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 power-
ful microcomputer which provides a highly-flexible and cost-effective solution to many 
embedded control applications.
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.
