Description
The 80C152JB JD is a ROMless extension of the 80C152 Universal Communication controller The 80C152JB has the same five 8-bit I O ports of the 80C152 plus an additional two 8-bit I O ports Port 5 and Port 6 The 80C152JB JD also has two additional control pins EBEN (EPROM Bus ENable) and EPSEN (EPROM bus Program Store ENable) EBEN selects the functionality of Port 5 and Port 6 When EBEN is low these ports are strictly I O similar to Port 4 The SFR location for Port 5 is 91H and Port 6 is 0A1H This
Features
- for peripheral I O interface and control Silicon implementations are much more cost effective than multi-wire cables found in board level parallel-toserial and serial-to-parallel converters The 83C152 contains in silicon all the features needed for the serialto-parallel conversion Other 83C152 benefits include 1) better noise immunity through differential signaling or www.
