XR16L788
HIGH PERFORMANCE OCTAL UART
SEPTEMBER 2001
REV. 1.1.4
GENERAL DESCRIPTION
The XR16L788
1
(788), formerly XR16L758, is a 5V
and 3.3V with 5V tolerant inputs octal Universal Asyn-
chronous Receiver and Transmitter (UART). The
highly integrated device is designed for high band-
width requirement in communication systems. A new
feature increases device driver efficiency includes a
global interrupt pin with global interrupt source regis-
ters that provide complete and detailed interrupt sta-
tus information for all 8 channels that will speed up in-
terrupt parsing. Other new facilities include simulta-
neous UART registers initialization, individual UART
channel soft-reset, DTR/DSR hardware flow control,
software flow control (Xoff/Xon) detection indicators,
RS-485 half-duplex direction control with programma-
ble turn-around delay, Intel or Motorola bus interface
and sleep mode now has a wake-up indicator.
