AX500-1BG896 ACTEL [Actel Corporation], AX500-1BG896 Datasheet - Page 21

• Manufacturer Part Number: AX500-1BG896
• Description: Axcelerator Family FPGAs
• Manufacturer: ACTEL [Actel Corporation]

Timing Characteristics
Axcelerator devices are manufactured in a CMOS process, therefore, device performance varies according to
temperature, voltage, and process variations. Minimum timing parameters reflect maximum operating voltage,
minimum operating temperature, and best-case processing. Maximum timing parameters reflect minimum operating
voltage, maximum operating temperature, and worst-case processing. The derating factors shown in
be applied to all timing data contained within this datasheet.
Table 2-7 • Temperature and Voltage Timing Derating Factors
All timing numbers listed in this datasheet represent sample timing characteristics of Axcelerator devices. Actual
timing delay values are design-specific and can be derived from the Timer tool in Actel’s Designer software after place-
and-route.

Notes:
1. The user can set the junction temperature in Designer software to be any integer value in the range of –55°C to 175°C.
2. The user can set the core voltage in Designer software to be any value between 1.4V and 1.6V.
