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
