AT89C2051-24PU MCU 8-bit 89C 8051 CISC 2KB Flash 5V 20-Pin PDIP
General Information :
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 Microchip’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 Microchip AT89C2051 is a powerful
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 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 continue functioning.
The power-down mode saves the RAM contents but freezes the
oscillator disabling all other chip functions until the next
hardware reset.
