2、1. Description The AT89C52 is a low-power, high-performance CMOS 8-bit microcomputer with 8K bytes of Flash programmable and erasable read only memory(PEROM). The device is manufactured using Atmels high density nonvolatile memory technology and is compatible with the industry standard 80C51 and 80C

3、52 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C52 is a powerful microcomputer which provides a highly flexib

5、 Programmable I/O Lines .Three 16-bit Timer/Counters Eight interrupt Sources Programmable Serial Channel Low Power Idle and Power Down Modes The AT89C52 provides the following standard features: 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines, three 16-bit timer/counters， a six-vector two-level in

6、terrupt architecture,a full duplex serial port, on-chip oscillator, and clock circuitry. In addition, the AT89C52 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 feezes the oscillator, disabling all other chip functions until the next hardware
