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. PCD3354A 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.
