PI7C9X754

High Performance 1.62V To 3.6V Quad Uart with 64-Byte FIFO

Description

Features

e PI7C9X754 (754), is a 1.62V to 3.6V quad Universal Asyn-

chronous Receiver and Transmitter (UART) with 5V tolerant se-

rial (modem) inputs. e highly integrated device is designed for

high bandwidth requirement in communication systems. Each

UART has its own 16C550 compatible set of conﬁguration regis-

ters, TX and RX FIFOs of 64 bytes, fully programmable transmit

and receive FIFO trigger levels, TX and RX FIFO level counters,

automatic RTS/CTS hardware ﬂow control with programmable

hysteresis, automatic soꢀware (Xon/Xoﬀ) ﬂow control, RS-485

half-duplex direction control, Intel or Motorola bus interface and

sleep mode for power saving.

ꢀÎ1.62V to 3.6V with 5V Tolerant Serial Inputs

ꢀÎProgrammable Sleep Mode with automatic wake-up

à Intel or Motorola Data Bus Interface select

ꢀÎEach UART is independently controlled with:

à 16C550 Compatible Register Set

à 64-byte Transmit and Receive FIFOs

à Transmit and Receive FIFO Level Counters

à Programmable TX and RX FIFO Trigger Levels for

DMA and Interrupt Generation

→ Programmable Receive FIFO Trigger Levels for

Soꢀware/Hardware Flow Control

→ Programmable hysteresis(Table A-D) for Soꢀware/

Hardware Flow Control

à Automatic RTS/CTS Flow Control

à Automatic Xon/Xoﬀ Soꢀware Flow Control with

Optional Data Flow Resume by Xon Any Character

→ DMA Signaling Capability for both Received and

Transmitted Data
