CMOS 2-WIRED SERIAL EEPROM
S-24C08A/16A
The S-24C08A/16A is a series of 2-wired, low power 8K/16K-bit
EEPROMs with a wide operating range. They are organized as 1K-word
×
8-bit, 2K-word
×
8-bit respectively. Each is capable of page write, and
sequential read.
The time for byte write and page write is the same, i. e., 1 msec. (max.)
during operation at 5 V ± 10%.
