This document describes the features and characteristics of the PCA3354C and PCD3354A 8-bit microcontrollers with DTMF generator and 256 bytes EEPROM.
This document is a product specification datasheet for the Philips PCA3354C and PCD3354A integrated circuits. These are 8-bit microcontrollers designed specifically for telephony applications, featuring an on-chip generator for dual tone multifrequency (DTMF), modem, and musical tones.
The devices include 8 kbytes of ROM, 256 bytes of RAM, and 256 bytes of Electrically Erasable Programmable Read Only Memory (EEPROM) for data storage without battery backup. They operate with a supply voltage range of 1.8 to 6 V and support CPU clock frequencies up to 16 MHz.
