Description:

(tp8xcx1bh) cmos single-chip 8-bit microcontroller.

TP80C31BH, (TP8xCx1BH) CMOS Single-Chip 8-Bit Microcontroller

VCC: Supply voltage during normal, Idle and Power Down operations.

VSS: Circuit ground.

Port 0: Port 0 is an 8-bit open drain bidirectional I/O port.

As an output port each pin can sink several LS TTL inputs.

Port 0 pins that have 1's written to them float, and in that state can be used as high-impe
