Notes: 1. When the operating voltage in read is V
CC
= 2.7 V to 3.6 V, the operating temperature
ranges for flash memory programming/erasing are T

= –20°C to +75°C. When the
operating voltage in read is V
CC
= 2.2 V to 3.6 V, the operating temperature ranges for
flash memory programming/erasing are T
