Electrical Parameters
5.4.3 Flash Memory Parameters
The data retention time of the TC1736’s Flash memory (i.e. the time after which stored
data can still be retrieved) depends on the number of times the Flash memory has been
erased and programmed.

1) Storage and inactive time included.
2) At average weighted junction temperature T_j = 100^oC, or
the retention time at average weighted temperature of T_j = 110^oC is minimum 10 years, or
the retention time at average weighted temperature of T_j = 150^oC is minimum 0.7 years.
3) In case the Program Verify feature detects weak bits, these bits will be programmed once more. The
reprogramming takes additional 5 ms.
