RECEIVER TRANSMITTER

(UART)

Note:

This data sheet summarizes the features

of the PIC32MX1XX/2XX/5XX 64/100-pin

family of devices. It is not intended to be

a comprehensive reference source. To

complement the information in this data

sheet, refer to Section 21. “Universal

Asynchronous Receiver Transmitter

(UART)” (DS60001107) in the “PIC32

Family Reference Manual”, which is

available from the Microchip web site

(www.microchip.com/PIC32).

The UART module is one of the serial I/O modules

available in PIC32MX1XX/2XX/5XX 64/100-pin family

devices. The UART is a full-duplex, asynchronous

communication channel that communicates with

peripheral devices and personal computers through

protocols, such as RS-232, RS-485, LIN and IrDA®.

The module also supports the hardware flow control

option, with UxCTS and UxRTS pins, and also includes

an IrDA encoder and decoder.

The primary features of the UART module are:

• Full-duplex, 8-bit or 9-bit data transmission

• Even, odd or no parity options (for 8-bit data)

• One or two Stop bits

• Hardware auto-baud feature

• Hardware flow control option

• Fully integrated Baud Rate Generator (BRG) with

16-bit prescaler

• Baud rates ranging from 38 bps to 12.5 Mbps at

50 MHz

• 8-level deep First-In-First-Out (FIFO) transmit

data buffer

• 8-level deep FIFO receive data buffer

• Parity, framing and buffer overrun error detection

• Support for interrupt-only on address detect 

(9th bit = 1)

• Separate transmit and receive interrupts

• Loopback mode for diagnostic support

• LIN Protocol support

• IrDA encoder and decoder with 16x baud clock

output for external IrDA encoder/decoder support

Figure 19-1 illustrates a simplified block diagram of the

UART.
