GENERAL DESCRIPTION
The PCD5095 is designed for GAP-compliant business
systems, PABX and WLL. Two modes can be selected:
three channel ADPCM CODEC with conversion of
ADPCM samples to linear PCM format and vice versa, the
second mode copies four ADPCM samples into two IOM
data buffers and vice versa. In both modes the DSP
controls the bidirectional data flow from the radio interface
and the IOM
-2 interface. The 80C51 controls the DECT
protocol and the IOM
-2 interface. The performance of the
embedded 80C51 microcontroller is twice the performance
of the classic architecture. The PCD5095 has 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 the Burst Mode Logic (BML),
the DSP and the System Data RAM (SDR).
