HD404652S Overview
The HD404654 Series is a member of the HMCS400-series of microputers designed to increase program productivity with large-capacity memory. Each microputer has a high-precision dual-tone multi-frequency (DTMF) generator, three timers, serial interface, voltage parator, and input capture circuit. The HD404654 Series includes three chips:.
