ST92F120 - ELECTRICAL CHARACTERISTICS

FLASH / EEPROM SPECIFICATIONS

(VDD = 5V ± 10%, TA = –40°C to +105°C, unless otherwise specified) (1)

Note:

(1) The full range of characteristics will be available after final product characterisation.

(2) Relationship computation between EEPROM sector cycling and single byte cycling is provided in a dedicated STMicroelectronics Appli-

cation Note (ref. AN1152).

FLASH / EEPROM DC & AC CHARACTERISTICS

(VDD = 5V ± 10%, TA = –40°C to +105°C, unless otherwise specified)

Note:

(1) Below the min value the FLASH / EEPROM can never be written; above the max value FLASH/EEPROM can always be written.

(2) Below the min value the FLASH / EEPROM can never be read; above the max value FLASH/EEPROM can always be read.
