OVERVIEW
The IS24C01-3 is a low cost 1,024-bit serial EEPROM. It
is fabricated using ISSI’s advanced CMOS EEPROM
technology and operates from a single supply.
The IS24C01-3 is internally organized as a 128 x 8
memory bank. The IS24C01-3 features a serial interface
and software protocol allowing operation on a simple
2-wire bus. Up to eight IS24C01-3s may be connected to
the 2-wire bus by programming the A0, A1, and A2 inputs.
