83C51FA microcontroller equivalent, event-control chmos single-chip 8-bit microcontroller.
make it an even more powerful microcontroller for applications that require Pulse Width Modulation High Speed I O and up down counting capabilities such as brake and trac.
that require Pulse Width Modulation High Speed I O and up down counting capabilities such as brake and traction control .
VCC Supply voltage 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-impedan.
