GENERAL DESCRIPTION

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.

FEATURES

? 8-bit CPU, ROM, RAM, EEPROM and I/O; in a single 28-lead or 32-lead package

? 8 kbytes user-programmable ROM (One-Time Programmable)

? 128 bytes RAM

? 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 temperature: ?25 to +70 °C

? Manufactured in silicon gate CMOS process.
