General Description
The SA2532P is a CMOS integrated circuit that
contains all the functions needed to form a high
performance electronic telephone.
The device incorporates LD/MF repertory dialling,
melody generation, ring frequency discrimination
and a high quality speech circuit.
Soft switch into temporary MF mode using * when
LD mode is selected .Timed Break Recall will be
available in both LD and MF dialling modes.
A 31 digit Last Number Redial (LNR) memory, with
moving cursor protocol, activated by single key
depression.
Line Loss Compensation whereby send and receive
gains are adjusted (by 6dB) over the ranges
selected by the LLC pin.
