GENERAL DESCRIPTION
The SA2531 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.
A RAM is on chip for a 31 digit last number redial and 14 memories each containing up to 21
digits. The sliding cursor procedure makes Last Number Redial easy behind a PABX.
The SA2531 (exept the SA2531D) incorporates a volume control for the earpiece. The receive
volume can be controlled by the VOL key (+4dB) or by the +/- keys (+6dB/-4dB in 5 steps).
The versatility of the circuit is provided by on chip programmability and a few external
components. This allows easy adaption to different PTT requirements without changing the
PCB of the telephone.
