XR16M554/554D
1.62V TO 3.63V QUAD UART WITH 16-BYTE FIFO
REV. 1.0.0
GENERAL DESCRIPTION
The XR16M554 (M554) is a quad Universal
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 M554 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 XR16M554IV (64-pin) offers three
state interrupt output while the XR16M554DIV
provides continuous interrupt output. The XR16M554
is compatible with the industry standard ST16C554.
