SC16C652B
Dual UART with 32-byte FIFOs and IrDA encoder/decoder
6.
Functional description
The SC16C652B 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 electronic circuitry to provide all these functions is fairly complex, especially
when manufactured on a single integrated silicon chip. The SC16C652B represents such
an integration with greatly enhanced features. The SC16C652B is fabricated with an
advanced CMOS process.
The SC16C652B is an upward solution that provides a dual UART capability with 32 bytes
of transmit and receive FIFO memory, instead of 16 bytes for the 16C2550 and none in
the 16C2450. The SC16C652B is designed to work with high speed modems and shared
network environments that require fast data processing time. Increased performance is
realized in the SC16C652B by the transmit and receive FIFOs. This allows the external
processor to handle more networking tasks within a given time. In addition, the four
selectable receive and transmit FIFO trigger interrupt levels are uniquely provided for
maximum data throughput performance especially when operating in a multi-channel
environment. The FIFO memory greatly reduces the bandwidth requirement of the
external controlling CPU, increases performance, and reduces power consumption.
The SC16C652B is capable of operation up to 5 Mbit/s with a 80 MHz clock. With a crystal
or external clock input of 7.3728 MHz, the user can select data rates up to 460.8 kbit/s.
The rich feature set of the SC16C652B is available through internal registers. Selectable
receive and transmit FIFO trigger levels, selectable TX and RX baud rates, and modem
interface controls are all standard features. Following a power-on reset or an external
reset, the SC16C652B is software compatible with the previous generation, SC16C2550
and ST16C2450.

I
Crystal or external clock input. Functions as a crystal input or as an external
clock input. A crystal can be connected between this pin and XTAL2 to form an
internal oscillator circuit. This conguration requires an external 1 M
resistor
between the XTAL1 and XTAL2 pins. Alternatively, an external clock can be
connected to this pin to provide custom data rates (see Section 6.8

Output of the crystal oscillator or buffered clock. (See also XTAL1.) Crystal
oscillator output or buffered clock output. Should be left open if an external clock is
connected to XTAL1. For extended frequency operation, this pin should be tied to
VCC via a 2 k resistor.
