Product specification

PCD3359A

1 FEATURES

• 8-bit CPU, ROM, RAM, EEPROM and I/O; in a single

28-lead or 32-lead package

• 2-kbyte ROM

• 64-byte RAM

• 128-byte EEPROM

• OTP version available

• Over 100 instructions (based on MAB8048) all of

1 or 2 cycles

• 20 quasi-bidirectional I/O port lines

• 8-bit programmable Timer/event counter 1

• 8-bit reloadable Timer 2

• Three single-level vectored interrupts:

– external

– 8-bit programmable Timer/event counter 1

– derivative; triggered by reloadable Timer 2

• Wake-up via external or Port 0 interrupt

• Two test inputs, one of which also serves as the external

interrupt input

• Reference for supply and temperature-independent

tone output

• Filtering for low output distortion (CEPT compatible)

• Melody output for ringer application

• Power-on-reset

• Stop and Idle modes

• Supply voltage: 1.8 to 6 V (DTMF tone output and

EEPROM erase/write from 2.5 V)

• Clock frequency: 1 to 16 MHz (3.58 MHz for DTMF

suggested)

• Operating temperature: −25 to +70 °C

• Manufactured in silicon gate CMOS process.

2 GENERAL 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. 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.
