The AT89C2051 designed as a effectively low-power, high-performance CMOS 8-bit microcontroller. It comes with 2K bytes of in-system programmable non-volatile storage manufactured using Atmel’s high-density non-volatile memory technology. Meanwhile, it is compatible with the industry-standard MCS-51 instruction set and pinout. The on-chip Flash on the chip permits the program memory to be reprogrammed in-system. Or via a standard non-volatile memory programmer.
In this Atmel microcontroller, by combining a flexible 8-bit CPU with in-system programmable Flash on a monolithic chip, Atmel AT89C2051 becomes effectively powerful microcontroller. In order that it delivers a highly flexible and affordable solution to various embedded control applications. Moreover, the Atmel AT89C2051 features 2K bytes of Flash, 128 bytes of RAM, 15 I/O lines, two 16-bit timer/counters. And also equipped with five vector two-level interrupt architecture, a full-duplex serial port interface, a precision analog comparator, on-chip oscillator and clock circuitry.
In addition to it, the AT89C2051 equipped with static logic for operation right down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the functioning of the CPU allowing the RAM, timer/counters, serial port, and interrupt system to continue their operation. Whereas, the Power-down mode saves the RAM contents but freezes the oscillator. Thereby disabling all other chip functions until the next external interrupt or hardware reset. These two features makes it suitable for battery operated applications.
