AT89S52-24PU ATMEL (爱特美尔) 8位微控制器
产品概述
ATMEL AT89S52-24PU 微控制器, 8位, 低电压 高性能 CMOS, AT89S52, 24 MHz, 8 KB, 256 Byte, 40 引脚, DIP
TheAT89S52-24PUis a low-power, high-performance CMOS 8-bit Microcontroller, uses Atmel"s high-density non-volatile memory technology and is compatible with the industry-standard 80C51 instruction set and pin-out. The on-chip flash allows the program memory to be reprogrammed in-system or by a conventional non-volatile memory programmer. By combining a versatile 8-bit CPU with in-system programmable flash on a monolithic chip, the Atmel AT89S52-24PU is a powerful microcontroller which provides a highly-flexible. It provides the following standard features 32 I/O lines, Watchdog timer, two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator and clock circuitry. In addition, the microcontroller is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes.
