AP87C54-20 CHMOS SINGLE-CHIP 8-BIT MICROCONTROLLER WITH 16 KBYTES USER PROGRAMMABLE EPROM

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 the VSS pin (pin 22) 4 Port 1 receives the low-order address bytes during EPROM programming and verifying Port 2 Port 2 is an 8-bit bidirectional I O port with internal pullups.

Features

of 16 Kbytes of program memory make it an even more powerful microcontroller for applications that require High Speed I O and up down counting capabilities such as brake and traction control Other brands and names are the property of their respective owners Information in this document is provided in connection with Intel products Intel assumes no liability whatsoever including infringement of any patent or copyright for sale and use of Intel products except as provided in Intel’s Terms and Conditions of Sale for such products Intel retains the right to make changes to these specifications at.
