1 / 12 page MC14469 MOTOROLA 1 Addressable Asynchronous Receiver/Transmitter CMOS The MC14469 receives one or two 11–bit words in a serial data stream. One of the incoming words contains the address and when the address matches, the MC14469 then transmits information in two 11–bit word data streams. Each of the transmitted words contains eight data bits, an even parity bit, and start and stop bits. The received word contains seven address bits with the address of the MC14469 set on seven pins. Therefore, 27 or 128 units can be interconnected in simplex or full–duplex data transmission. In addition to the address received, seven command bits may be received for general–purpose data or control use. The MC14469 finds application in transmitting data from remote analog–to– digital converters, remote MPUs, or remote digital transducers to the master computer or MPU. • Supply Voltage Range: 4.5 V to 18 V • Low Quiescent Current: 75 µA Maximum @ 5 V, 25°C • Guaranteed Data Rates to 4800 Baud @ 5 V, to 9600 Baud @ 12 V • Receive — Serial to Parallel Transmit — Parallel to Parallel • Transmit and Receive Simultaneously in Full Duplex • Crystal or Resonator Operation for On–Chip Oscillator • See Application Note AN806A • Chip Complexity: 1200 FETs or 300 Equivalent Gates PIN ASSIGNMENTS P SUFFIX 5 4 3 2 1 8 7 6 37 38 39 40 34 35 36 33 C6 C5 C4 C0 VDD C1 C2 C3 A0 RESET OSC2 OSC1 A3 A2 A1 A4 13 12 11 10 9 16 15 14 29 30 31 32 26 27 28 25 S4 S3 S2 VAP CS SEND S0 S1 ID1 ID0 A6 A5 ID4 ID3 ID2 ID5 17 20 19 18 22 23 24 21 TRO S7 S6 S5 RI ID7 ID6 VSS FN SUFFIX 28 27 26 25 24 23 22 21 20 19 18 40 41 42 43 44 1 2 3 4 5 6 29 30 31 32 33 34 35 36 37 38 39 17 16 15 14 13 12 11 10 9 8 7 S3 S2 S1 S0 SEND NC VAP CS C6 C5 C4 ID4 ID3 ID2 ID1 ID0 NC A6 A5 A4 A3 A2 NC = NO CONNECTION Order this document by MC14469/D MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14469 P SUFFIX PLASTIC DIP CASE 711 FN SUFFIX PLCC PACKAGE CASE 777 ORDERING INFORMATION MC14469P Plastic DIP MC14469FN PLCC Package 40 1 44 1 © Motorola, Inc. 1995 |
