v1.2
(June 2008)
TJ, Maximum Junction Temperature, was changed to 100° from 110 in the
"Thermal Characteristics" section and EQ 2-2. The calculated result of Maximum
Power Allowed has thus changed to 1.463 W from 1.951 W.
2-5
Values for the A3P015 device were added to Table 2-7 Quiescent Supply
Current Characteristics.
2-6
Values for the A3P015 device were added to Table 2-14 Different Components
Contributing to Dynamic Power Consumption in ProASIC3 Devices. PAC14 was
removed. Table 2-15 Different Components Contributing to the Static Power
Consumption in ProASIC3 Devices is new.
2-10,
2-11
The "PLL Contribution—PPLL" section was updated to change the PPLL formula
from PAC13 + PAC14 * FCLKOUT to PDC4 + PAC13 * FCLKOUT.
2-13
Both fall and rise values were included for tDDRISUD and tDDRIHD in
Table 2-93 Input DDR Propagation Delays.
2-71
Table 2-98 A3P015 Global Resource is new.
2-79
The typical value for Delay Increments in Programmable Delay Blocks was
changed from 160 to 200 in Table 2-106 ProASIC3 CCC/PLL Specification.
2-83
v1.1
(January 2008)
Table note references were added to Table 2-2 Recommended Operating
Conditions 1, and the order of the table notes was changed.
2-2
The title for Table 2-4 Overshoot and Undershoot Limits 1 was modified to
remove "as measured on quiet I/Os." Table note 1 was revised to remove
"estimated SSO density over cycles." Table note 2 was revised to remove "refers
only to overshoot/undershoot limits for simultaneous switching I/Os.
"
2-3
The "Power per I/O Pin" section was updated to include 3 additional tables
pertaining to input buffer power and output buffer power.
2-6
Table 2-29 I/O Output Buffer Maximum Resistances 1 was revised to include
values for 3.3 V PCI/PCI-X.
2-24
Table 2-81 LVDS Minimum and Maximum DC Input and Output Levels was
updated.
2-59
v1.0
(January 2008)
In Table 2-2 Recommended Operating Conditions 1, TJ was listed in the symbol
column and was incorrect. It was corrected and changed to TA.
2-2
In Table 2-3 Flash Programming Limits – Retention, Storage and Operating
Temperature1, Maximum Operating Junction Temperature was changed from
110°C to 100°C for both commercial and industrial grades.
2-2
The "PLL Behavior at Brownout Condition" section is new.
2-3
In the "PLL Contribution—PPLL" section, the following was deleted:
FCLKIN is the input clock frequency.
2-13
In Table 2-21 Summary of Maximum and Minimum DC Input Levels, the note
was incorrect. It previously said TJ and it was corrected and changed to TA.
