8-bit Microcontrollers With DTMF Generator, 8 Kbytes OTP And 128 Bytes EEPROM

This data sheet details the specific properties of the PCD3755A PCD3755E and PCD3755F. The devices differ in their Port and Power-on-reset configurations. References to PCD3755x apply to all three types. The devices are members of the PCD33xxA family of Microcontrollers The shared properties of the family are described in the PCD33xxA family data sheet, which should be read in conjunction with this publication. The PCD3755A PCD3755E and PCD3755F are One-Time Programmable (OTP) 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 (P1.7/MDY) for melody generation, providing ringer operation.
