REVISION HISTORY
Date
Revision
Description
February 2002
4.0
Changed to standard style format. Text descriptions were clarified and simplified (eg.
DMA operation, FIFO mode vs. Non-FIFO mode operations etc). Clarified timing dia-
grams. Renamed Rclk (Receive Clock) to Bclk (Baud Clock) and timing symbols.
Added TAH, TCS and OSC.
April 2002
4.1
Changed A0-A7 in Figures 15 and 16 to A0-A2. Clarified MCR bit-3 description.
September 2003 4.2
Changed to single column format. Added Device Status to Ordering Information.
Devices with top markings of "A2 YYWW" and newer have 5V tolerant inputs. Devices
with top markings of "CC YYWW" and older do not have 5V tolerant inputs.
April 2004
4.2.1
Corrected unit of clock pulse duration (CLK) in AC Electrical Characteristics table from
’MHz’ to ’ns’.
August 2004
4.3.1
Updated the AC Timing values for CS, IOR, IOW and TDY parameters.
October 2004
4.4.0
The AC and DC Electrical Characteristics tables apply to devices with top mark date
code of "A2 YYWW" and newer.
January 2011
4.4.1
Corrected the "Voltage at any pin" to "GND-0.3V to +5.5V" in the "Absolute maximum
ratings" table on the page 26.
