产品简介 :

The FT24C64B series are 65,536 bits of serial Electrical Erasable and Programmable Read Only Memory, commonly known as EEPROM. They are organized as 8192 words of 8 bits (one byte) each.  They offer an additional page (Identification Page) of 32 bytes. They also provide the Write Device Address instruction for users to implement configurable device address features. The devices are fabricated with proprietary advanced CMOS process for low power and low voltage applications. The device features programmable software write protection which provides partial as well as full memory array protection. These devices are available in thin 4-ball WLCSP package.  A standard 2-wire serial interface is used to address all read and write functions.  Our extended VCC range (1.7V to 5.5V) devices enables wide spectrum of applications.
