ATMEL  AT89C2051-24SU  微控制器, 8位, 高性能 CMOS, AT89C2051, 24 MHz, 2 KB, 128 Byte, 20 引脚, SOIC

The is a 8-bit low-voltage, high-performance CMOS Microcomputer with 2kB of flash programmable and erasable read-only memory PEROM. The device is manufactured using Atmel"s high-density non-volatile 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 powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications. The AT89C2051 provides the following standard features, 2kB 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 analogue 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.
