REVISION HISTORY
DATE
REVISION
DESCRIPTION
September 2006
P1.0.0
Preliminary Datasheet.
February 2007
P1.0.1
Updated Thermal Resistance Data.
June 2007
1.0.0
Final Datasheet. Clarified pin descriptions. Updated DC Electrical Specifications.
June 2009
1.0.1
Added UART Channel B select to Table 3.
June 2011
1.0.2
Removed “DMA mode” since this is a legacy feature that is not supported in this
device. Added and updated maximum SPI clock frequency to the AC Electrical Char-
acteristics table for SPI-Bus Timing. Updated ordering information.
July 2012
1.1.0
Clarified "OP2#" pin since the M1172 does not have OP2# output pin.
Changed "AC Electrical Characteristics-UART Clock" table according to the PCN12-
0614-02.
October 2013
1.2.0
Clarified descriptions for FIFO and non-FIFO mode operation. Updated 32-pin QFN
and 28-pin TSSOP package drawings.
ECN 1342-25
