ST16C554/554D
2.97V TO 5.5V QUAD UART WITH 16-BYTE FIFO
JUNE 2006
REV. 4.0.1
GENERAL DESCRIPTION
The ST16C554/554D (554) 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 1.5
Mbps. 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 554 is available in a 64-pin
LQFP and a 68-pin PLCC package.
The 64-pin
package only offers the 16 mode interface, but the
68-pin
package
offers
an
additional
68
mode
interface which allows easy integration with Motorola
processors.
The ST16C554CQ64 (64-pin) offers
three
state
interrupt
output
while
the
ST16C554DCQ64
provides
continuous
interrupt
output. The 554 combines the package interface
modes of the 16C554 and 68C554 on a single
integrated chip.
