产品概述 返回TOP
The CX24C32A/B provides 32768 bits of serial electrically erasable and programmable readonly memory (EEPROM), organized as 4096 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential.The CX24C32A/B offers an additional page, named the Identification Page (32 bytes). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode.
