Advance Information

MC68176 2-BIT A/D CONVERTER IC

The MC68176 chip is part of a total solution available from Motorola for providing FLEX™

paging capabilities in a low-power, low-cost system. Working in conjunction with standard

paging receivers, the MC68176 takes the 4-level baseband audio signals from the receiver and

performs 2-bit A/ D using 8-bit DACs for peak and valley detection, passing the 2-bit digital

signal directly to the MC68175 FLEX chip or MC68181 Roaming FLEX chip for further decoding

and FLEX protocol handling. Received messages are then passed to the host microcontroller or

microprocessor via the Serial Peripheral Interface (SPI). The host processor (running

FLEXstack™ software) interprets the data appropriately (as binary, alphanumeric or numeric

message types), and handles all I/ O and user interaction functions.

The FLEX paging protocol is the multi-speed, high-performance protocol adopted by leading

service providers worldwide. FLEX protocol gives service providers the increased capacity,

added reliability, and enhanced pager battery performance required today. It also provides an

upward migration path to the service provider which is completely transparent to the end user.
