Description

The PCD3349A provides 4 kbytes of Program Memory, 224 bytes of RAM and 20 I/O lines. The PCD3349A is a microcontroller which has been designed primarily for telecom applications. It includes an on-chip dual tone multi-frequency (DTMF) generator. The instruction set is based on that of the MAB8048 and is software compatible with the PCD33xxA family.

This data sheet details the specific properties of the PCD3349A. The shared characteristics of the PCD33xxA family of microcontrollers are described in the "PCD33xxA Family" data sheet and also in "Data Handbook IC03; Section PCD33xxA Family", which should be read in conjunction with this publication.
