GENERAL DESCRIPTION
The PCD5094 is designed for GAP-compliant
basestations offering conference call between the a/b line
and two handsets and answering machine switch. It has an
embedded 80C51 microcontroller with twice the
performance of the classic architecture, 64 kbytes of
PROM program memory and 3 kbytes of data memory on
chip. In addition there is 1 kbyte of on-chip data memory
that is shared with on-chip Burst Mode Logic (BML) and
DSP, the System Data RAM (SDR).
