18.0 UNIVERSAL ASYNCHRONOUS
RECEIVER TRANSMITTER
(UART)
Note:
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
“PIC24F Family Reference Manual”,
“UART” (DS39708). The information in
this data sheet supersedes the information
in the FRM.
The Universal Asynchronous Receiver Transmitter
(UART) module is one of the serial I/O modules available
in the PIC24F 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 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 the UxCTS
and UxRTS Pins
• Fully Integrated Baud Rate Generator with 16-Bit
Prescaler
• Baud Rates Ranging from 15 bps to 1 Mbps at
16 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
(9^th bit = 1)
• Transmit and Receive Interrupts
• Loopback mode for Diagnostic Support
• Support for Sync and Break Characters
• Supports Automatic Baud Rate Detection
• IrDA^® Encoder and Decoder Logic
• 16x Baud Clock Output for IrDA Support
A simplified block diagram of the UARTx is shown in
Figure 18-1. The UARTx module consists of these key
important hardware elements:
• Baud Rate Generator
• Asynchronous Transmitter
• Asynchronous Receiver

Note:
The UARTx inputs and outputs must all be assigned to available RPn/RPIn pins before use. See Section 11.4
“Peripheral Pin Select (PPS)” for more information.
