产品简介 :

The FT25C32A is 32768 bits of serial Electrical Erasable and Programmable Read Only Memory, commonly known as EEPROM. They are organized as 4096 words of 8 bits (1 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 and 8-lead TSSOP packages. The memory is accessed via a simple Serial Peripheral Interface (SPI) compatible serial bus. The   pin may be used to suspend any serial communication without resetting the serial sequence. While the device is paused, transitions on its inputs will be ignored. Our extended VCC range (1.8V to 5.5V) devices enables wide spectrum of applications.
