2.1 Operating Conditions

(Ask a Question)

The following table lists the absolute maximum ratings of Axcelerator devices. Stresses beyond the ratings may cause permanent damage to the device. Exposure to Absolute Maximum rated conditions for extended periods may affect device reliability.

Table 2-1. Absolute Maximum Ratings
Symbol	Parameter	Limits	Units
VCCA	DC core supply voltage	–0.3 to 1.7	V
VCCI	DC I/O supply voltage	–0.3 to 3.75	V
VREF	DC I/O reference voltage	–0.3 to 3.75	V
VI	Input voltage	–0.5 to 4.1	V
VO	Output voltage	–0.5 to 3.75	V
TSTG	Storage temperature	–60 to +150	°C
VCCDA¹	Supply voltage for differential I/Os	–0.3 to 3.75	V
T_J	Junction Temperature	–55 to 135	°C

Note:

Should be the maximum of all VCCI.

Devices should not operate outside the recommendations given in the following table.

Table 2-2. Recommended Operating Conditions
Parameter Range	Commercial	Industrial	Military	Units
Ambient Temperature (T_A)	0 to +70	–40 to +85	–55 to +125	°C
Junction Temperature (T_J)¹	0 to +85	–40 to +100	–55 to +125	°C
1.5V Core Supply voltage	1.425 to 1.575	1.425 to 1.575	1.425 to 1.575	V
1.5V I/O Supply voltage	1.425 to 1.575	1.425 to 1.575	1.425 to 1.575	V
1.8V I/O Supply voltage	1.71 to 1.89	1.71 to 1.89	1.71 to 1.89	V
2.5V I/O Supply voltage	2.375 to 2.625	2.375 to 2.625	2.375 to 2.625	V
3.3V I/O Supply voltage	3.0 to 3.6	3.0 to 3.6	3.0 to 3.6	V
VCCDA Supply voltage	3.0 to 3.6	3.0 to 3.6	3.0 to 3.6	V
VPUMP Supply voltage	3.0 to 3.6	3.0 to 3.6	3.0 to 3.6	V

Note:

Libero sets the junction temperature to maximum 70 °C for Commercial (C), 85 °C for Industrial (I), 125 °C for Military (M) temperature grades. Users can override the default up to 85, 100, 125 °C max for the respective C, I and M temperature grades to verify timing closure at expected operating junction temperature.
