Changes
The
"V
CCPLA/B
PLL Supply Voltage"
pin description was updated to include the
following statement:
Actel recommends tying VCCPLX to VCC and using proper filtering circuits to
decouple V
CC
noise from PLL.
The
"V
COMPLA/B
Ground for West and East PLL" section
was updated.
In
Table 2-47 • ADC Characteristics in Direct Input Mode,
the commercial conditions
were updated and note 2 is new.
The V
CC33ACAP
signal name was changed to
"XTAL1 Crystal Oscillator Circuit
Input".
Table 2-48 • Uncalibrated Analog Channel Accuracy*
is new.
Table 2-49 • Calibrated Analog Channel Accuracy
1,2,3
is new.
Table 2-50 • Analog Channel Accuracy: Monitoring Standard Positive Voltages
is
new.
In
Table 2-57 • Voltage Polarity Control Truth Table—AV (x = 0), AC (x = 1), and AT
(x = 3)*,
the following I/O Bank names were changed:
Hot-Swap changed to Standard
LVDS changed to Advanced
In
Table 2-58 • Prescaler Op Amp Power-Down Truth Table—AV (x = 0), AC (x = 1),
and AT (x = 3),
the following I/O Bank names were changed:
Hot-Swap changed to Standard
LVDS changed to Advanced
In the title of
Table 2-64 • I/O Standards Supported by Bank Type,
LVDS I/O was
changed to Advanced I/O.
The title was changed from "Fusion Standard, LVDS, and Standard plus Hot-Swap
I/O" to
Table 2-68 • Fusion Standard and Advanced I/O Features.
In addition, the
table headings were all updated. The heading used to be Standard and LVDS I/O
and was changed to Advanced I/O. Standard Hot-Swap was changed to just
Standard.
This sentence was deleted from the
"Slew Rate Control and Drive Strength" section:
The Standard hot-swap I/Os do not support slew rate control. In addition, these
references were changed:
• From: Fusion hot-swap I/O (Table 2-69 on page 2-122) To: Fusion Standard I/O
• From: Fusion LVDS I/O (Table 2-70 on page 2-122) To: Fusion Advanced I/O
The
"Cold-Sparing Support" section
was significantly updated.
In the title of
Table 2-75 • Fusion Standard I/O Standards—OUT_DRIVE Settings,
Hot-Swap was changed to Standard.
In the title of
Table 2-76 • Fusion Advanced I/O Standards—SLEW and OUT_DRIVE
Settings,
LVDS was changed to Advanced.
In the title of
Table 2-81 • Fusion Standard and Advanced I/O Attributes vs. I/O
Standard Applications,
LVDS was changed to Advanced.
In
Figure 2-111 • Naming Conventions of Fusion Devices with Three Digital I/O
Banks
and
Figure 2-112 • Naming Conventions of Fusion Devices with Four I/O
Banks
the following names were changed:
Hot-Swap changed to Standard
LVDS changed to Advanced
