Description
8-bit CPU, ROM, RAM, EEPROM and I/O; all in a 44-lead quad flat package - 8 kbytes ROM; 256 bytes RAM - 256 bytes Electrically Erasable Programmable Read Only Memory (EEPROM) - Over 100 instructions (based on MAB8048) all of 1 or 2 cycles - 36 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 - Programmable DTMF clock divider - 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) - CPU clock frequency: 1 to 16 MHz (3.58 MHz or 10.74 MHz for DTMF) - Operating ambient temperature: – -25 to +70 °C (PCD3354A) – 0 to 50 °C (PCA3354C) - Manufactured in silicon gate CMOS process. 3 This data sheet details the specific properties of the PCA3354C and PCD3354A.
