3 / 36 page  1999 Oct 28 3 Philips Semiconductors Product specification 8-bit microcontrollers with DTMF generator and 128 bytes EEPROM PCA3351C; 52C; 53C; PCD3351A; 52A; 53A 1 FEATURES • 8-bit CPU, ROM, RAM, EEPROM and I/O; all in one (28-lead or 32-lead) package • ROM: – 2 kbytes (PCA3351C and PCD3351A) – 4 kbytes (PCA3352C and PCD3352A) – 6 kbytes (PCA3353C and PCD3353A) • RAM: – 64 bytes (PCA3351C and PCD3351A) – 128 bytes (PCA3352C, PCD3352A, PCA3353C and PCD3353A) • 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 ambient temperature: −25 to +70 °C or 0to50 °C • Manufactured in silicon gate CMOS process. 2 GENERAL DESCRIPTION This data sheet details the specific properties of the devices referred to. 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. • ‘PCA3351C; 52C; 53C’ denotes the types PCA3351C, PCA3352C and PCA3353C. Unless specified, these types will hereafter be referred to collectively as ‘PCA335xC’. • ‘PCD3351A; 52A; 53A’ denotes the types PCD3351A, PCD3352A, PCD3353A. Unless specified, these types will hereafter be referred to collectively as ‘PCD335xA’. The PCA335xC and PCD335xA are 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 for melody generation, providing ringer operation. The PCA335xC and PCD335xA also incorporate 128 bytes of EEPROM, permitting data storage without battery backup. The EEPROM can be used for storing telephone numbers, particularly for implementing redial functions. The PCA335xC and PCD335xA can be emulated with the OTP microcontrollers PCD3755A and PCD3755E. See Chapter 14, Table 25. The instruction set is similar to that of the MAB8048 and is a sub-set of that listed in the “PCD33xxA family” data sheet. The differences between PCA335xC and PCD335xA are shown in Table 1. Table 1 Differences: PCA335xC and PCD335xA Note 1. See Chapter 14, Table 26. TYPE VPOR AMBIENT TEMP. RANGE PCA335xC fixed at 2.0 V ±0.3 V 0 to 50 °C PCD335xA (1.2 to 3.6 V) ±0.5 V(1) −25 to +70 °C |
