2 GENERAL 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.

6 FREQUENCY GENERATOR

A versatile frequency generator section is provided (see Fig.3). For normal operation, use a 3.58 MHz quartz crystal or PXE resonator. The frequency generator includes precision circuitry for dual tone multifrequency (DTMF) signals, which is typically used for tone dialling telephone sets.

The TONE output can alternatively issue twelve modem frequencies for data rates between 300 and 1200 bits/s.

In addition to DTMF and modem frequencies, two octaves of musical scale in steps of semitones are available.

6.1 Frequency generator derivative registers

Table 2 gives the derivative addresses, mnemonics and access types of the frequency generator derivative registers. The addresses 03H to FFH are not used.

Table 2 Addresses of the frequency generator derivative registers

Notes

1. HGF = High Group Frequency; access type W.

2. LGF = Low Group Frequency; access type W.
