7 31 8 temporary data storage RAM
8 Serial I / O port pin makes the least number of ways
9 Read / write clock or RAM data transmission when there are two single-byte transmit and multi-byte character sets transfer mode
10 8-pin DIP package or optional 8-pin SOIC package assembly according to the surface
Size : 44mmX23mmX1.6mm / 1.7''X0.9''/0.06'' ( approach )
Working Temperature: 0°~+70°
Operating Voltage Range:3.3v ~ 5V
Note : Do not reverse VCC and GND, will it cause damage
It requires a pull-up resistor for P0 port of 51 MCU, if without, you can connect the data cable to other terminal
