GENERAL DESCRIPTION

The TC520A Serial Interface Adapter provides logic control for TelComs TC500/500A/510/514 family of dual slope, integrating A/D converters. It directly manages TC500 converter phase control signals A, B, and CMPTR thereby reducing host processor task loading and software complexity. Communication with the TC520A is accomplished over a 3 wire serial port. Key converter operating parameters are programmable for complete user flexibility.
