FEATURES
• 8-bit CPU, ROM, RAM, EEPROM and I/O; all in one
(28-lead or 32-lead) package
• ROM:
– 2 kbytes (PCA3351C and PCD3351A)
– 4 kbytes (PCA3352C and PCD3352A)
– 6 kbytes (PCA3353C and PCD3353A)
• RAM:
– 64 bytes (PCA3351C and PCD3351A)
– 128 bytes (PCA3352C, PCD3352A, PCA3353C and
PCD3353A)
• 128 bytes Electrically Erasable Programmable
Read-Only Memory (EEPROM)
• 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
• Two test inputs, one of which also serves as the external
interrupt input
• DTMF, modem, musical tone generator
• 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 ambient temperature: −25 to +70 °C or
0to50
°C
• Manufactured in silicon gate CMOS process.

GENERAL DESCRIPTION
This data sheet details the specific properties of the
devices referred to. 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.
• ‘PCA3351C; 52C; 53C’ denotes the types PCA3351C,
PCA3352C and PCA3353C. Unless specified, these
types will hereafter be referred to collectively as
‘PCA335xC’.
• ‘PCD3351A; 52A; 53A’ denotes the types PCD3351A,
PCD3352A, PCD3353A. Unless specified, these types
will hereafter be referred to collectively as ‘PCD335xA’.
The PCA335xC and PCD335xA are microcontrollers
designed primarily for telephony applications. They
include an on-chip generator for dual tone multifrequency
(DTMF), modem and musical tones. In addition to dialling,
generated frequencies can be made available as square
waves for melody generation, providing ringer operation.
The PCA335xC and PCD335xA also incorporate
128 bytes of EEPROM, permitting data storage without
battery backup. The EEPROM can be used for storing
telephone numbers, particularly for implementing redial
functions.
The PCA335xC and PCD335xA can be emulated with the
OTP microcontrollers PCD3755A and PCD3755E.
See Chapter 14, Table 25.
The instruction set is similar to that of the MAB8048 and is
a sub-set of that listed in the
“PCD33xxA family” data
sheet.
The differences between PCA335xC and PCD335xA are
shown in Table 1.
