Features
1.STC89C52 is a high-speed / low-power / super anti-jamming / ultra-low-cost microcontroller, the instruction code is fully compatible with the traditional 8051 microcontroller, 12 clocks per machine cycle and 6 clocks per machine cycle can be intended to choose.
2.51 microcontroller development board using STC89C52RC-LQFP-44 main control chip, on-board USB to TTL serial chip CH340, easy to download programs and serial communication experiments.
3. Micro USB interface, comes with a download circuit a cell phone data line can be downloaded.
4. No welding pin, easy to design their own use, can be upward or downward welding pin, connected to the 2.54 pitch multi-purpose board and other applications.
5. Ultra-low power consumption design, normal operating mode 4mA-7mA, power-down mode can be woken up by an external interrupt, suitable for battery-powered systems, such as water meters, gas meters, portable devices.

Note
1. On the P0 port pull-up resistor, if you use the STC89C52 version, P0 port if you do the external output driver, you need to external pull-up resistor, do the general LCD bus such as LCD1602, LCD12864 bus, can be used directly, no external pull-up resistor.
2. Different batches, product appearance and pin color is slightly different, the same function!
