GENERAL DESCRIPTION
The XR16C850
*1
(850) is a universal asynchronous
receiver and transmitter (UART) and is pin compatible
with the ST16C550,ST16C650A, and TI’s TL16C750
UART. The 850 is an enhanced UART with 128 byte
FIFOs, automatic hardware/software flow control, and
data rates up to 1.5Mbps. It includes transmit/receive
FIFO counters to increase data loading and unloading
throughput. Onboard status registers provide error indi-
cations and operational status. Modem interface con-
trol is included and can be optionally configured to
operate with the Infrared (IrDA) encoder/decoder. Inter-
nal loopback allows onboard diagnostics. The 850 is
available in 40-pin PDIP, 44-pin PLCC, 48-pin TQFP,
and 52-pin QFP packages. The 44, 48, and 52 pin
versions provide both the standard (STD) mode or PC
mode. The STD mode is compatible with the ST16C450,
ST16C550, ST16C650A and TL16C750 while the PC
mode supports standard PC COM port connections.
The 40 PDIP pin package does not offer the PC mode.
