1 Description
The M24M02-DR is a 2 Mb I
2
C-compatible EEPROM (Electrically Erasable PROgrammable
Memory) organized as 256 K × 8 bits.
The M24M02-DR ca
n operate with a supply voltage from 1.8 V to 5.5 V, over an ambient
temperature range of –40 °C / +85 °C.
The M24M02-DR of
fers an additional page, named the Identification Page (256 bytes). The
Identification Page can be used to store sensitive application parameters which can be
(later) permanently locked in Read-only mode.
