INTERFACING THE TLV1549 10-BIT SERIAL-OUT ADC TO POPULAR 3.3-V MICROCONTROLLERSThe TLV1549, 10-bit serial-out A/ D converter operates with a 3.3-V (+/- 0.3 V) single supply. The device uses a switched-capacitor successive approximation method to perform the A/D conversion in a maximum of 21 µs. This document describes interfacing the TLV1549 to three microcontrollors, 68HC05, TMS70C02, and 80C51-L, which operate from a single 3.3-V supply rail. Each interface requires no glue logic. Relocatable assembler software listings are provided for the interfaces to each microcontroller.
