ST16C554/554D

ST68C554

QUAD UART WITH 16-BYTE FIFOS

DESCRIPTION

TheST16C554Disauniversalasynchronousreceiver

and transmitter (UART) with a dual foot print interface.

The 554D is an enhanced UART with 16 byte FIFOs,

receive trigger levels and data rates up to 1.5Mbps.

Onboard status registers provide the user with error

indications and operational status, modem interface

control. System interrupts may be tailored to meet

user requirements. An internal loopback capability

allows onboard diagnostics. The 554D is available in

64 pin TQFP, and 68 pin PLCC packages. The 68 pin

PLCC package offer an additional 68 mode which

allowseasyintegrationwithMotorola, andotherpopu-

lar microprocessors. The ST16C554CQ64 (64 pin)

offers three state interrupt control while the

ST16C554DCQ64 provides constant active interrupt

outputs. The 64 pin devices do not offer TXRDY/

RXRDY outputs. The 554D combines the package

interface modes of the 16C554 and 68C554 series on

a single integrated chip.
