CMOS 2-WIRE SERIAL EEPROM
S-24C01A/02A/04A
The S-24C0XA is a series of 2-wired, low power 1K/2K/4K-bit EEPROMs
with a wide operating range. They are organized as 128-word × 8-bit,
256-word × 8-bit, and 512-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%.
