Functional description

The SC16C650B provides serial asynchronous receive data synchronization,

parallel-to-serial and serial-to-parallel data conversions for both the transmitter and

receiver sections. These functions are necessary for converting the serial data

stream into parallel data that is required with digital data systems. Synchronization for

the serial data stream is accomplished by adding start and stop bits to the transmit

data to form a data character (character orientated protocol). Data integrity is insured

by attaching a parity bit to the data character. The parity bit is checked by the receiver

for any transmission bit errors. The SC16C650B is fabricated with an advanced

CMOS process to achieve low drain power and high speed requirements.

The SC16C650B is an upward solution that provides 32 bytes of transmit and receive

FIFO memory, instead of none in the 16C450, or 16 in the 16C550. The SC16C650B

is designed to work with high speed modems and shared network environments that

require fast data processing time. Increased performance is realized in the

SC16C650B by the larger transmit and receive FIFOs. This allows the external

processor to handle more networking tasks within a given time. In addition, the four

selectable levels of FIFO trigger interrupt and automatic hardware/software ﬂow

control is uniquely provided for maximum data throughput performance, especially

when operating in a multi-channel environment. The combination of the above greatly

reduces the bandwidth requirement of the external controlling CPU, increases

performance, and reduces power consumption.

The SC16C650B is capable of operation up to 3 Mbit/s with a 48 MHz external clock

input (at 5 V).

The rich feature set of the SC16C650B is available through internal registers.

Automatic hardware/software ﬂow control, selectable transmit and receive FIFO

trigger level, selectable TX and RX baud rates, modem interface controls, and a sleep

mode are some of these features.
