ORDERING INFORMATION
(see note 1)
This data sheet details the specific properties of the
PCA3354C and PCD3354A. 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 PCA3354C and PCD3354A are microcontrollers
oriented towards telephony applications. They include
8 kbytes ROM, 256 bytes RAM, 36 I/O lines, and an
on-chip generator for dual tone multifrequency (DTMF),
modem and musical tones. In addition to dialling, the
generated frequencies can be made available as square
waves for melody generation, providing ringer operation.
The PCA3354C and PCD3354A also incorporate
256 bytes of EEPROM, permitting data storage without
battery backup. The EEPROM can be used for storing
telephone numbers, particularly for implementing redial
functions.
The differences between PCA3354C and PCD3354A are
shown in Table 1.
The instruction set is similar to the MAB8048 and is a
sub-set of that listed in the
“PCD33xxA family”
data sheet.
