Description

This data sheet details the specific properties of the PCD3359A. The shared properties of the PCD33xxA family of microcontrollers are described in the "PCD33xxA family" data sheet, which should be read in conjunction with this publication.

The PCD3359A is a low voltage microcontroller oriented towards telephony applications. PCD3359A includes an on-chip generator for dual tone multifrequency (DTMF) generator, modem and musical tones. In addition to dialling, generated frequencies can be made available as square waves (P1.7/MDY) for melody generation, providing ringer operation (in which case the TONE output is disabled). A wake-up function via Port 0 interrupt facilitates keyboard interfacing. The PCD3359A can be emulated with the OTP microcontroller PCD3756A.

PCD3359A also incorporates 128 bytes of Electrically Erasable Programmable Read-Only Memory (EEPROM). The EEPROM can be used for storing telephone numbers, particularly for implementing redial functions of PCD3359A. The instruction set is similar to that of the MAB8048 and is a sub-set of that listed in the "PCD33xxA family" data sheet.
