产品信息

The CAV24C02 is a 2-kb CMOS Serial EEPROM device organized internally as 16 pages of 16 bytes each. This device supports both the Standard (100 kHz) as well as Fast (400 kHz) I
C protocol.
Data is written by providing a starting address, then loading 1 to 16 contiguous bytes into a Page Write Buffer, and then writing all data to non-volatile memory in one internal write cycle. Data is read by providing a starting address and then shifting out data serially while automatically incrementing the internal address count.
External address pins make it possible to address up to eight CAV24C02 devices on the same bus.

Automotive Temperature Grade 1 (-40°C to +125°C)
2.5 V to 5.5 V Supply Voltage Range
These Devices are PbFree, Halogen Free/BFR Free and are RoHS Compliant

pcb制造：AT24C02芯片工作原理
其中A0、A1、A2用于定义芯片地址（后面会详细说明），VCC和GND是供电正负接口，SCL和SDA是IIC的数据总线，WP是写保护（若接VCC则该芯片所有内容都被保护，只能读不能写，一般我们直接接地）。
