7.2 Rev. B – 01/2012
7.3 Rev. A – 12/2011
1. Updated the datasheet with new Atmel blue logo and the last page.
2. Added Flash errata.
1. Description: DFLL frequency is 20 to 150MHz, not 40 to 150MHz.
2. Description: “One touch sensor can be configured to operate autonomously...” replaced by “All
touch sensors can be configured to operate autonomously...”.
3. Block Diagram: GCLK_IN is input, not output, and is 2 bits wide (GCLK_IN[1..0]). CAT SMP
corrected from I/O to output. SPI NPCS corrected from output to I/O.
4. Package and Pinout: PRND signal removed from Signal Descriptions List table and GPIO
Controller Function Multiplexing table.
5. Supply and Startup Considerations: In 1.8V single supply mode figure, the input voltage is
1.62-1.98V, not 1.98-3.6V. “On system start-up, the DFLL is disabled” is replaced by “On
system start-up, all high-speed clocks are disabled”.
6. ADCIFB: PRND signal removed from block diagram.
7. Electrical Characteristics: Added PLL source clock in the Clock Frequencies table in the
Maximum Clock Frequencies section. Removed 64-pin package information from I/O Pin
Characteristics tables and Digital Clock Characteristics table.
8. Electrical Characteristics: Removed USB Transceiver Characteristics, as the device contains
no USB.
9. Mechanical Characteristics: Added notes to package drawings.
10. Summary: Removed Programming and Debugging chapter, added Processor and Architecture
chapter.
11. Datasheet Revision History: Corrected release date for datasheet rev. A; the correct date is
12/2011.
1. Initial revision.
