Digests are a cryptographic hash of various data areas. Any digest that reports back an error raises the digest tamper flag.

LF = Lifetime factor as defined by the number of programming cycles the device has seen under the conditions listed in the following table. Table 121 • FPGA Programming Cycles Lifetime Factor LF Programming Cycles Programming TJ 1 500 –40 °C to 100 °C 0.8 1000 –40 °C to 85 °C 0.6 2000 –40 °C to 55 °C Notes: • The maximum number of device digest cycles is 100K. • Digests are operational only over the –40 °C to 100 °C temperature range. • After a program cycle, an additional N digests cycles are allowed with the resultant retention characteristics for the total operating and storage temperature shown. • Retention is specified for total device storage and operating temperature. • All temperatures are junction temperatures (TJ). 94 Microsemi Proprietary and Confidential.
