Revision
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 T
Changed A0-A7 in Figures
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.
Corrected unit of clock pulse duration (CLK) in AC Electrical Characteristics table from
’MHz’ to ’ns’.
Updated the AC Timing values for CS, IOR, IOW and TDY parameters.
The AC and DC Electrical Characteristics tables apply to devices with top mark date
code of "A2 YYWW" and newer.
Corrected the "Voltage at any pin" to "GND-0.3V to +5.5V" in the "Absolute maximum
ratings" table on the page 26.
