Revision

v2.0, Revision 1

(continued)

Changes

The

"Typical Performance Characteristics" section

is new.

Table 2-49 • Analog Channel Specifications

was significantly updated.

Table 2-50 • ADC Characteristics in Direct Input Mode

was significantly updated.

Table 2-52 • Calibrated Analog Channel Accuracy 1,2,3,

note 2 was updated.

Table 2-53 • Analog Channel Accuracy: Monitoring Standard Positive Voltages,

note 1 was updated.

Table 2-54 • ACM Address Decode Table for Analog Quad,

bit 89 was removed.

The data in the 2.5 V LCMOS and LVCMOS 2.5 V / 5.0 V rows were updated in

Table 2-75 • Fusion Standard and Advanced I/O – Hot-Swap and 5 V Input Tolerance

Capabilities.

Table 2-78 • Fusion Standard I/O Standards—OUT_DRIVE Settings,

LVCMOS

1.5 V, for OUT_DRIVE 2, was changed from a dash to a check mark.

The

"VCC15A Analog Power Supply (1.5 V)"

definition was changed from "A 1.5 V

analog power supply input should be used to provide this input"

"1.5 V clean analog power supply input for use by the 1.5 V portion of the analog

circuitry."

In the

"VCC33PMP Analog Power Supply (3.3 V)"

pin description, the following text

was changed from "VCC33PMP should be powered up before or simultaneously

with VCC33A"

"VCC33PMP should be powered up simultaneously with or after VCC33A."

The

"VCCOSC Oscillator Power Supply (3.3 V)" section

was updated to include

information about when to power the pin.

In the

"128-Bit AES Decryption" section,

FIPS-192 was incorrect and changed to

FIPS-197.

The note in

Table 2-84 • Fusion Standard and Advanced I/O Attributes vs. I/O

Standard Applications

was updated.

For 1.5 V LVCMOS, the VIL and VIH parameters, 0.30 * VCCI was changed to 0.35 *

VCCI and 0.70 * VCCI was changed to 0.65 * VCCI in

Table 2-86 • Summary of

Maximum and Minimum DC Input and Output Levels Applicable to Commercial and

Industrial Conditions, Table 2-87 • Summary of Maximum and Minimum DC Input

and Output Levels Applicable to Commercial and Industrial Conditions,

and

Table 2-88 • Summary of Maximum and Minimum DC Input and Output Levels

Applicable to Commercial and Industrial Conditions.

Table 2-87 • Summary of Maximum and Minimum DC Input and Output Levels

Applicable to Commercial and Industrial Conditions,

the VIH max column was

updated.

Table 2-89 • Summary of Maximum and Minimum DC Input Levels Applicable to

Commercial and Industrial Conditions

was updated to include notes 3 and 4. The

temperature ranges were also updated in notes 1 and 2.

The titles in

Table 2-92 • Summary of I/O Timing Characteristics – Software Default

Settings

Table 2-94 • Summary of I/O Timing Characteristics – Software Default

Settings

were updated to "VCCI = I/O Standard Dependent."
