Introduce STC89c52 in detail. Talk about the difference between it and 5 1, and the characteristics and advantages of STC series single chip microcomputer, preferably a little more.

5 1 has only 4K program storage space, and 52 has 8K.

5 1 only 128 bytes of data storage space, 52 has 256.

5 1 has only two timers, and 52 has three.

STC MCU is a series of MCU with 5 1 kernel. STC microcontroller is a single clock/machine cycle microcontroller produced by Acer. It is a new generation of 805 1 single chip microcomputer with high speed, low power consumption and super anti-interference. The instruction code is completely compatible with the traditional 805 1, but it is 8- 12 times faster and has an internal integration of Max 865438+.

Extended data:

STC89C52RC is a low-power, high-performance CMOS8-bit microcontroller produced by STC company, which has an 8kbyte system programmable flash memory. STC89C52 adopts the classic MCS-5 1 kernel, but many improvements have been made to make the chip have functions that the traditional 5 1 single chip microcomputer does not have.

It has the following standard functions: 8k bytes of Flash, 5 12 bytes of RAM, 32-bit I/O port line, watchdog timer, built-in 4KB EEPROM, MAX8 10 reset circuit, 3 16-bit timers/counters, 4 external interrupts, and a 7-vector 4-level interrupt structure (compatible with the traditional 5-level interrupt structure) In addition, STC89C52 can be reduced to 0Hz static logic operation, which supports two software selection power saving modes.
