XR16V2550/2551/2552

High Performance DUART with 16-Byte FIFO

Ideal for High Speed Data Transmission

he XR16V2550/XR16V2551/XR16V2552 (XR16V255x) product

family consists of two high performance universal asynchronous

receiver-transmitter (UART) with 16 byte transmit and receive FIFOs.

Each UART is compatible to the industry standard 16550 UART, but with

enhanced features such selectable TX and RX FIFO trigger levels,

automatic hardware (RTS/CTS) flow control, automatic software

(XON/XOFF) flow control, sleep mode, and a fractional baud rate

generator.

In addition, the XR16V2551 has two additional features: Intel/Motorola

bus select and PowerSave mode. The XR16V2551 can operate in either

Major Features

the Intel bus mode (CS#, IOR#, IOW#) or the Motorola bus mode (CS#,

R/W#). The XR16V2550 and XR16V2552 can operate only in the Intel

bus mode. When the XR16V2551 is in the sleep mode, the PowerSave

mode can further reduce the power consumption by isolating the address,

data and control lines from the CPU.

• 2.25 to 3.63 Volt Operation

• 5 Volt Tolerant Inputs

• Two independent UART channels

• Register set compatible to

XR16L2550

The fractional baud rate generator is a new feature that provides more

flexibility on the selection of a clock or crystal frequency. Traditionally,

the baud rate generator allowed divisors of 1 to 2¹⁶in increments of 1. By

being limited to whole numbers, there were only specific clock or crystal

frequencies that could be used depending on what baud rate (or data rate)

each channel is operating at. With the new fractional baud rate generator,

divisors can be from 1 to (2¹⁶- 0.0625) in increments of 0.0625 (or 1/16).

The fractional divisor allows the use of non-standard clock frequency to

be used to generate standard baud rates and the use of standard clock

frequency to generate non-standard baud rates.

• Data rate of up to 16 Mbps at

3.3V, and 12.5 Mbps at 2.5 V

with 4X sampling rate

• Fractional Baud Rate Generator

• Transmit and Receive FIFOs of

16 bytes

• Programmable TX and RX FIFO

Trigger Levels

All devices operate from 2.25 to 3.63 volts with 5 Volt tolerant inputs.

Each channel of the XR16V255x is capable of data rates up to 16 Mbps

at 3.3V with a 4X sampling clock. The XR16V255x is pin and software

compatible with previous generation ST16C255x and XR16L255x

UART families. The XR16V2550 and XR16V2551 are available in

48-pin TQFP and 32-pin QFN packages. The XR16V2552 is available in

44-pin PLCC and 32-pin QFN packages.
