Note
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. It 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.
The device 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.
The instruction set is similar to that of the MAB8048 and is
a sub-set of that listed in the
“PCD33xxA family”
data
sheet.
