This datasheet also covers the N87C51FA variant, as both devices belong to the same (n87c51fx) chmos single-chip 8-bit microcontroller family and are provided as variant models within a single manufacturer datasheet.
Description
VCC Supply voltage VSS Circuit ground VSS1 Secondary ground (in PLCC only) Provided to reduce ground bounce and improve power supply by-passing NOTE This pin is NOT a substitute for VSS pin (pin 22) Port 0 Port 0 is an 8-bit open drain bidirectional I O port As an output port each pin can sink seve
