DESCRIPTION
The FT24C32A/64A series are 32768/65536 bits of serial Electrical Erasable and Programmable Read Only Memory,
commonly known as EEPROM. They are organized as 4096/8192 words of 8 bits (one byte) each. The devices are
fabricated with proprietary advanced CMOS process for low power and low voltage applications. These devices are
available in standard 8-lead DIP, 8-lead SOP, 8-lead TSSOP, 8-lead MSOP, 8-lead DFN, and 5-lead SOT23 packages.
A standard 2-wire serial interface is used to address all read and write functions. Our extended VCC range (1.8V to
5.5V) devices enables wide spectrum of applications.
