Table 19. Record of Revisions
Changed 1.8 VDC supply voltage to ±5%.
Clarified Industrial and Commercial temperature ranges; removed MMC/SD as a
boot device.
Removed 1.8 VDC I/O capability (VDD).
Changed “BOOTWIDTH” to “WIDTH” for consistency.
Extensively revised to make more usable.
Minor corrections to Slew Rate and Output Drive on some cells.
Revised Boot Mode table to show various device possibilities.
External Boot Modes table Added.
Changed ‘MAXIMUM’ test conditions from maximum temperature to nominal temperature.
Changed Synchronous Memory Interface tISD to 2.5 ns.
Changed MMC timing reference to ‘MMC Clock Periods’; minor changes to
several timing values; changed ADC resolution value.
Altered low pass filter description.
Minor text editing for clarity.
Minor editorial corrections.
Paragraph added explaining sequencing of power supplies.
Added ground connection to drawing and removed the “Caution” box.
Clarified Note 1.
Temperature/Voltage/Speed chart and Table added.
Rolled revision to Version 1.1.
Cleaned up formatting.
Added sub-bullet limiting voltage on the oscillator pins.
Corrected reset state of several pins.
SCLK drive corrected from 24 mA to 20 mA.
Added text to allow power up sequencing longer than 100
within 1.5 V.
Added “Typ.” column and corrected values for IACTIVE, IHALT, ISTANDBY. Added
note (3) to clarify IACTIVE operating parameters.
Changed Asynchronous Memory timing to match SRAM datasheet parameter naming
conventions. Corrected Asynchronous Memory values for tOHCA,
tOHRA, tOHSDW, tOHSC, and tOHD; added value for tOHA. Corrected
PCMCIA D[31:0] timing values tISD and tIHD.
