NOTE:
1. If erase and program endurance is n times (n = 100), each block can be erased n times. For example, if a 4-
Kbyte block A is erased after programming a word data 2,048 times, each to a different address, this counts as
one erase and program time. Data can not be programmed to the same address more than once without
erasing the block. (rewrite prohibited)
Erase and program endurance
Word program time (16 bits) (VCC1 = 5.0 V, Topr = 25°C)
Lock bit program time
Block erase time
(VCC1 = 5.0 V, Topr = 25°C)
Wait time to stabilize flash memory circuit
Data hold time (Topr = -40 to 85°C)
Flash Memory Electrical Characteristics (VCC1 = 4.5 V to 5.5 V, 3.0 to 3.6 V,
Topr = 0 to 60°C unless otherwise specified)
