SC16C554B/554DB  
5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.) with 16-byte  
FIFOs  
Rev. 4 — 8 June 2010  
Product data sheet  
1. General description  
The SC16C554B/554DB is a 4-channel Universal Asynchronous Receiver and  
Transmitter (QUART) used for serial data communications. Its principal function is to  
convert parallel data into serial data and vice versa. The UART can handle serial data  
rates up to 5 Mbit/s. It comes with an Intel (16 mode) or Motorola (68 mode) interface.  
The SC16C554B/554DB is pin compatible with the ST16C554 and TL16C554 and it will  
power-up to be functionally equivalent to the 16C454. Programming of control registers  
enables the added features of the SC16C554B/554DB. Some of these added features are  
the 16-byte receive and transmit FIFOs, four receive trigger levels. The  
SC16C554B/554DB also provides DMA mode data transfers through FIFO trigger levels  
and the TXRDY and RXRDY signals. (TXRDY and RXRDY signals are not available in the  
HVQFN48 package.) On-board status registers provide the user with error indications,  
operational status, and modem interface control. System interrupts may be tailored to  
meet user requirements. An internal loopback capability allows on-board diagnostics.  
The SC16C554B/554DB operates at 5 V, 3.3 V and 2.5 V, and the industrial temperature  
range, and is available in plastic PLCC68, LQFP64, LQFP80, and HVQFN48 packages.  
On the HVQFN48 package only, channel C has all the modem pins. Channels A and B  
have only RTSn and CTSn pins and channel D does not have any modem pin.  
2. Features and benefits  
„ 4 channel UART  
„ 5 V, 3.3 V and 2.5 V operation  
„ Industrial temperature range (−40 °C to +85 °C)  
„ The SC16C554B is pin and software compatible with the industry-standard  
ST16C454/554, ST68C454/554, ST16C554, TL16C554  
„ The SC16C554DB is pin and software compatible with ST16C554D, and software  
compatible with ST16C454/554, ST16C554, TL16C554  
„ Up to 5 Mbit/s data rate at 5 V and 3.3 V, and 3 Mbit/s at 2.5 V  
„ 5 V tolerant on input only pins1  
„ 16-byte transmit FIFO  
„ 16-byte receive FIFO with error flags  
„ Programmable auto-RTS and auto-CTS  
‹ In auto-CTS mode, CTS controls transmitter  
‹ In auto-RTS mode, RX FIFO contents and threshold control RTS
