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 “PCD33 xx A
Family” data sheet and also in “Data Handbook IC03;
Section PCD33 xx A Family” , which should be read in
conjunction with this publication.
