REV. 1.2.3
HIGH PERFORMANCE 2.97V TO 5.5V QUAD UART
REVISION HISTORY
REVISION
DESCRIPTION
P1.0.0
Preliminary
1.0.1
Further clarification on A0-A7, RTS#, CTS#, DTR#, DSR# and ENIR pin description and throughout the
datasheet, change VIH from 2.2V to 2.4V at 5V, change VOH from 2.4V to 2.0 at 3.3V and from 4V to 2.4V at
5V, change ICC from 10 to 5mA and its test condition to 2MHz. clock, and ISLEEP to 0.6 and 1.5mA for 3.3V and
5V respectively. Revised the AC timing table.
1.0.2
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.
1.1.0
(June 2003) Added Device Status to Ordering Information.
1.2.0
(June 2004) 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 0x04 for devices with top mark date code of "D2 YYWW".
1.2.1
(February 2005) Corrected Trigger Table selection and programmable trigger level selection in
1.2.2
(October 2005) Updated the 1.4mm-thick Quad Flat Pack package description from "TQFP" to "LQFP" to be
consistent with the JEDEC and Industry norms. Clarified wake-up interrupt in Sleep Mode description.
1.2.3
(July 2008) Corrected description of Xon/Xoff/Special character interrupt.
