XR16L788
HIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART
REV. 1.2.3
REVISION HISTORY
Revision
Description
P1.0.0
Preliminary
P1.0.1
Corrected figure 2 pin diagram on pins 16 to 30 and 39.
P1.0.2
Corrected pins description (pin number) for TX3, RX6, DSR6# and 16/68#.
P1.0.3
Changed part number to XR16L788, added 5V spec and target timing, and corrected RX6 pin to be 39.
P1.0.4
Changed Icc to 5mA max. and Isleep current to 400uA max, clarified ENIR pin and MCR bits 2 and 6.
1.1.0
Updated Electrical Specification Tables. Added
θ-ja and θ-jc values. Removed Preliminary designation.
1.1.1
Changed VIL ( 0.8 to 0.7 max) and VIH (2.2 to 2.4 min) in electrical characteristics tables.
1.1.2
Changed Isleep max @ 3.3V from 0.40mA to 0.60 mA and @ 5V from 0.40 to 3.00mA
1.1.3
Deleted VOH @ Iout =6mA. Changed condition on ICC from CLK=35MHz to “EXT Clock=2Mhz”. Changed
TRDA from min =30ns to 35ns. Changed max VOL @5V from 0.4 to 0.55V. Changed min VOH @5V from 4.0 to
2.4V.
1.1.4
Updated values of AC Electrical Characteristics (TAS, TAH, TCS, TRD, TADS, TADH, TWDS, TWDH). Added Exar’s
UART Technical Support E-mail address to first and last page.
1.2.0
(April 2004) Added Device Status to Ordering Information and date to Revision History. Changed to single col-
umn format. Clarified pin descriptions- changed from using logic 1 and logic 0 to HIGH (VCC) and LOW
(GND) for input and output pin descriptions. Added VOH vs. IOH and VOL vs. IOL curves (
Figure 16 and
Figure 17). Clarified Transmit and Receive interrupt timing diagrams (Figure 21-Figure 24). DREV regis-
ter was updated to 0x08 for devices with top mark date code of "H2 YYWW".
1.2.1
(February 2005) Corrected Trigger Table selection and programmable trigger level selection in
1.2.2
(October 2005) Clarified wake-up interrupt in Sleep Mode description.
1.2.3
(July 2008) Corrected decription of Xon/Xoff/Special character interrupt.
