ST16C654/654D  
2.97V TO 5.5V QUAD UART WITH 64-BYTE FIFO  
OCTOBER 2003  
REV. 5.0.0  
FEATURES  
GENERAL DESCRIPTION  
1
Pin-to-pin compatible with ST16C454, ST16C554  
The ST16C654/654D (654) is an enhanced quad  
Universal Asynchronous Receiver and Transmitter  
(UART) each with 64 bytes of transmit and receive  
FIFOs, transmit and receive FIFO trigger levels,  
automatic hardware and software flow control, 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. Selectable interrupt polarity  
provides flexibility to meet design requirements. An  
internal loopback capability allows onboard  
diagnostics. The 654 is available in 64 pin TQFP, 68  
pin PLCC and 100 pin QFP packages. The 64 pin  
package only offers the 16 mode interface, but the 68  
and 100 pin packages offer an additional 68 mode  
interface which allows easy integration with Motorola  
processors. The ST16C654CQ64 (64 pin) offers  
and TI’s TL16C554AFN and TL16C754BFN  
Intel or Motorola Data Bus Interface select  
Four independent UART channels  
Register Set Compatible to 16C550  
Data rates of up to 1.5 Mbps  
64 Byte Transmit FIFO  
64 Byte Receive FIFO with error tags  
4 Selectable TX and RX FIFO Trigger Levels  
Automatic Hardware (RTS/CTS) Flow Control  
Automatic Software (Xon/Xoff) Flow Control  
Progammable Xon/Xoff characters  
Wireless Infrared (IrDA 1.0) Encoder/Decoder  
Full modem interface

output  
while  
the  
Sleep Mode (200 uA typical)  
ST16C654DCQ64 provides continuous interrupt  
output. The 100 pin package provides additional  
FIFO status outputs (TXRDY# and RXRDY# A-D),  
separate infrared transmit data outputs (IRTX A-D)  
and channel C external clock input (CHCCLK). The  
ST16C654/654D is compatible with the industry  
standard ST16C454 and ST16C654/554D.  
Crystal oscillator or external clock input
