Rev. 3.20
QUAD UNIVERSAL ASYNCHRONOUS
RECEIVER/TRANSMITTER (UART)
DESCRIPTION
The ST16C454 is a universal asynchronous receiver
and transmitter (UART) with a dual foot print interface.
The 454 is an enhanced UART with data rates up to
1.5Mbps and software compatible to ST16C450.
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 loop-back capability
allows onboard diagnostics. The ST16C454 offer an
additional 68 mode which allows easy integration with
Motorola, and other popular microprocessors. The
454 combines the package interface modes of the
ST16C454 and ST68C454 series on a single inte-
grated chip.
FEATURES
• Software compatibility with the Industry Standard
16C450
• 1.5 Mbps transmit/receive operation (24MHz)
• Independent transmit and receive control
• Software selectable Baud Rate Generator
• Modem control signals (-CTS, -RTS, -DSR, -DTR,
-RI, -CD)
• Programmable character lengths (5, 6, 7, 8)
• Even, odd, or no parity bit generation and detection
• Internal loop-back diagnostics
• TTL compatible inputs, outputs
• Low power
