General description
The SC16C650B is a Universal Asynchronous Receiver and Transmitter (UART) 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 3 Mbit/s.
The SC16C650B is pin compatible with the ST16C650A and it will power-up to be
functionally equivalent to the 16C450. Programming of control registers enables the
added features of the SC16C650B. Some of these added features are the 32-byte receive
and transmit FIFOs, automatic hardware or software ow control and infrared
encoding/decoding. The selectable auto-ow control feature signicantly reduces software
overload and increases system efciency while in FIFO mode by automatically controlling
serial data ow using RTS output and CTS input signals. The SC16C650B also provides
DMA mode data transfers through FIFO trigger levels and the RXRDY and TXRDY
signals. 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 SC16C650B operates at 5 V, 3.3 V and 2.5 V, and the industrial temperature range,
and is available in plastic PLCC44, LQFP48, and HVQFN32 packages.
