ST16C650A
2.90V TO 5.5V UART WITH 32-BYTE FIFO
JANUARY 2004
GENERAL DESCRIPTION
REV. 5.0.0
The ST16C650A
1
(650A) is a 2.90 to 5.5 volt
Universal Asynchronous Receiver and Transmitter
(UART) with 5 volt tolerant inputs. This device
supports Intel and PC ISA mode data bus interfaces
and is software compatible to industry standard
16C450, 16C550, ST16C580 and ST16C650A
UARTs.
The 650A has 32 bytes of TX and RX FIFOs and is
capable of operating up to serial data rates of 3.125
Mbps at 5 volt supply voltage. The internal registers
include the 16C550 register set plus Exar’s enhanced
registers for additional features to support today’s
highly demanding data communication needs. The
enhanced features include automatic hardware and
software flow control, selectable TX and RX trigger
levels, and wireless infrared (IrDA) encoder/decoder.
The device provides a new capability to give user the
ability to program the wireless infrared encoder
output pulse width, hence reducing the power
consumption of a handheld unit.
The ST16C650A device comes in the 44-pin PLCC
and 48-pin TQFP packages in both the commercial
and industrial temperature ranges.
