8-bit microcontroller with DTMF generator
Product specification
PCD3349A
1 FEATURES
• 8-bit CPU, ROM, RAM, I/O in a single 28-lead package
• 4-kbyte ROM
• 224-byte RAM
• 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
• 2 single-level vectored interrupts:
– external
– Timer/event counter 1
• Two test inputs, one of which also serves as the external
interrupt input
• DTMF tone generator
• Reference for supply and temperature-independent
TONE output
• Filtering for low output distortion (CEPT compatible)
• Power-on-reset
• Stop and Idle modes
• Supply voltage: 1.8 to 6 V (DTMF TONE output from
2.5 V)
• Low standby voltage of 1 V
• Low Stop mode current of 1 µA (typical)
• Clock frequency: 1 to 16 MHz (3.58 MHz for DTMF
suggested)
• Manufactured in silicon gate CMOS process.
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.
