General description

The SC28L201 is a high performance UART. Its functional and programming features

closely match but greatly extend those of previous Philips UARTs. Its conﬁguration on

power-up is similar that of the SC26C92. Its differences from the previous Philips UARTs

are: 256-character receiver, 256-character transmit FIFOs, 3.3 V and 5 V compatibility,

8 I/O ports for arbitrating interrupt system and overall faster bus and data speeds and is

fabricated in an advanced 0.5 micron CMOS process.

It is a member of the IMPACT line of data communications parts.

Pin programming will allow the device to operate with either the Motorola or Intel bus

interface by changing the function of some pins (reset is inverted, DACKN, and IACKN

enabled, for example).

The Philips Semiconductors SC28L201 Universal Asynchronous Receiver/Transmitter

(UART) is a single-chip CMOS-LSI communications device that provides a full-duplex

asynchronous receiver/transmitter channel in a single package. It interfaces directly with

microprocessors and may be used in a polled or interrupt driven system. The use of the

Interrupt system provides intelligent interrupt vectors.

The operating mode and data format of the channel may be programmed independently.

Additionally, the receiver and transmitter can select its operating speed as one of

twenty-seven ﬁxed baud rates; a 16

× clock derived from one of two programmable

counter/timers, or an external 1

× or 16× clock. The baud rate generator and counter/timer

can operate directly from a crystal or from external clock inputs. The ability to

independently program the operating speed of the receiver and transmitter make the

UART particularly attractive for dual-speed channel applications such as clustered

terminal systems and bridges.

Each receiver and transmitter is buffered by 256-character FIFOs to nearly eliminate the

potential of receiver overrun, transmitter underrun and to reduce interrupt overhead in

interrupt driven systems. In addition, a ﬂow control capability (Xon/Xoff and RTS/CTS) is

provided to disable a remote transmitter when the receiver buffer is full.

Also provided on the SC28L201 is a multipurpose 8-bit I/O for the channel. These can be

used as general-purpose I/O ports or can be assigned speciﬁc functions (such as clock

inputs or status and interrupt outputs) under program control. Normally they will be used

for modem control and DMA interface. All ports have change of state detectors and input

sections are always active making output signals available to the internal circuits and the

control processor.

The SC28L201 is available in a TSSOP48 package. For other package options, contact

Philips.
