XR16V554/554D

2.25V TO 3.6V QUAD UART WITH 16-BYTE FIFO

MAY 2007

REV. 1.0.1

FEATURES

GENERAL DESCRIPTION

• Pin-to-pin compatible with ST16C454, ST16C554,

The XR16V554 (V554) is

quad Universal

TI’s TL16C554A and Philip’s SC16C554B

Asynchronous Receiver and Transmitter (UART) with

16 bytes of transmit and receive FIFOs, selectable

receive FIFO trigger levels and data rates of up to 4

Mbps at 3.3 V. Each UART has a set of registers that

provide the user with operating status and control,

receiver error indications, and modem serial interface

controls. An internal loopback capability allows

onboard diagnostics. The V554 is available in a 48-

pin QFN, 64-pin LQFP, 68-pin PLCC and 80-pin

LQFP packages. The 64-pin and 80-pin packages

only offer the 16 mode interface, but the 48- and 68-

pin packages offer an additional 68 mode interface

which allows easy integration with Motorola

processors. The XR16V554IV (64-pin) offers three

state interrupt output while the XR16V554DIV

provides continuous interrupt output. The XR16V554

is compatible with the industry standard ST16C554.

• Intel or Motorola Data Bus Interface select

• Four independent UART channels

■ Register Set Compatible to 16C550

■ Data rates of up to 4 Mbps at 3.3 V and 3.125

Mbps at 2.5 V

■ 16 byte Transmit FIFO

■ 16 byte Receive FIFO with error tags

■ 4 Selectable RX FIFO Trigger Levels

■ Full modem interface

• 2.25V to 3.6V supply operation

• Crystal oscillator or external clock input

APPLICATIONS

• Portable Appliances

• Telecommunication Network Routers

• Ethernet Network Routers

• Cellular Data Devices

• Factory Automation and Process Controls
