Table 25.13 Flash Memory Characteristics

Conditions: V

CC = PLLVCC = DrVCC = 3.0 V to 3.6 V, AVCC = 3.0 V to 3.6 V, Vref = 3.0 V to AVCC,

SS = PLLVSS = DrVSS = AVSS = 0 V,

Operating temperature range during programming/erasing:

a = 0°C to +75°C (regular specifications),

a = 0°C to +85°C (wide-range specifications)

Notes: 1. Programming time and erase time depend on data in the flash memory.

2. Programming time and erase time do not include time for data transfer.

3. All the characteristics after programming are guaranteed within this value (guaranteed

value is from 1 to Min. value).

4. Characteristics when programming is performed within the Min. value
