2、terrupted dual-career UART serial passage, low power consumption, leisure and fall after fall electric power mode can be awakened and continuous watchdog timer and double-number pointer, power identifier.Efficacy: characteristicsSTC89C52 is one kind of low power consumption, high CMOS8 bit micro-con

3、troller, 8K in system programmable Flash memory. Use high-density nonvolatile storage technology, and industrial 80C51 product instruction and pin fully compatible. The Flash memory chips allows programs in the system, also suitable for programmable conventional programming. In a single chip, have c

4、lever 8 bits CPU and online system programmable Flash, increase STC89C52 for many embedded control system to provide high vigorous application and useful solutions. STC89C52 has following standard efficacy: 8k byte Flash RAM, 256 bytes, 32 I/O port, the watchdog timer, two, three pointer numerical 1

5、6 timer/counter, a 6 vector level 2 continuous structure, the serial port, working within crystals and horological circuit. In addition, 0Hz AT89S52 can drop to the static logic operation, support two software can choose power saving mode. Idle mode, the CPU to stop working, and allows the RAM, time

6、r/counters, serial, continuous to work. Protection asana pattern, RAM content is survival, vibrators frozen, SCM, until all the work under a continuous or hardware reset. 8-bit microcontrollers 8K bytes in the system programmable Flash AT89S52 devices.Mouth: P0 P0 mouth is a two-way open drain I/O.

7、As export, each can drive eight TTL logic level. For P0 port to write 1, foot as the high impedance input.When access to external programs and numerical memory, also known as low P0 mouth eight address/numerical reuse. In this mode, with the internal P0 resistor.In the flash when programming, also u

When the program requires external, calibration on pull-up resistors.Mouth: P1 mouth P1 is an internal resistance of the eight two-way I/O buffers can drive, P1 output four TTL logic level. To write 1 P1 p
