dsPIC33EPXXXGS70X/80X FAMILY

20.0 UNIVERSAL ASYNCHRONOUS

RECEIVER TRANSMITTER

(UART)

The dsPIC33EPXXXGS70X/80X family of devices

contains two UART modules.

The Universal Asynchronous Receiver Transmitter

(UART) module is one of the serial I/O modules avail-

able in the dsPIC33EPXXXGS70X/80X device family.

The UART is a full-duplex, asynchronous system that

can communicate with peripheral devices, such as

personal computers, LIN/J2602, RS-232 and RS-485

interfaces. The module also supports a hardware flow

control option with the UxCTS and UxRTS pins, and

also includes an IrDA® encoder and decoder.

The primary features of the UARTx module are:

• Full-Duplex, 8 or 9-Bit Data Transmission through

the UxTX and UxRX Pins

• Even, Odd or No Parity Options (for 8-bit data)

• One or Two Stop bits

• Hardware Flow Control Option with UxCTS and

UxRTS Pins

• Fully Integrated Baud Rate Generator with

16-Bit Prescaler

• Baud Rates Ranging from 4.375 Mbps to 67 bps in

16x mode at 70 MIPS

• Baud Rates Ranging from 17.5 Mbps to 267 bps in

4x mode at 70 MIPS

• 4-Deep First-In First-Out (FIFO) Transmit Data

Buffer

• 4-Deep FIFO Receive Data Buffer

• Parity, Framing and Buffer Overrun Error Detection

• Support for 9-Bit mode with Address Detect

(9th bit = 1)

• Transmit and Receive Interrupts

• A Separate Interrupt for all UARTx Error Conditions

• Loopback mode for Diagnostic Support

• Support for Sync and Break Characters

• Support for Automatic Baud Rate Detection

•IrDA® Encoder and Decoder Logic

• 16x Baud Clock Output for IrDA Support

A simplified block diagram of the UARTx module is

shown in Figure 20-1. The UARTx module consists of

these key hardware elements:

• Baud Rate Generator

• Asynchronous Transmitter

• Asynchronous Receiver
