Description
The AT24C01A/02/04/08/16 provides 1024/2048/4096/8192/16384 bits of serial elec-
trically erasable and programmable read only memory (EEPROM) organized as
128/256/512/1024/2048 words of 8 bits each. The device is optimized for use in many
industrial and commercial applications where low power and low voltage operation are
essential. The AT24C01A/02/04/08/16 is available in space saving 8-pin PDIP,
( A T 2 4 C 0 1 A / 0 2 / 0 4 / 0 8 / 1 6 ) , 8 - P i n M S O P ( A T 2 4 C 0 1 A / 0 2 ) , 8 - P i n T S S O P
( A T 2 4 C 0 1 A / 0 2 / 0 4 / 0 8 / 1 6 ) , a n d 8 - P i n a n d 1 4 - P i n J E D E C S O I C
(AT24C01A/02/04/08/16) packages and is accessed via a 2-wire serial interface. In
addition, the entire family is available in 5.0V (4.5V to 5.5V), 2.7V (2.7V to 5.5V), 2.5V
(2.5V to 5.5V) and 1.8V (1.8V to 5.5V) versions.
