The BR24T128FVT-WE2 is an EEPROM IC (Integrated Circuit) device manufactured by ROHM. It is a low power serial non-volatile EEPROM with 128Kbits of memory, and an I2C bus with 2-wire data communication. This device has a 8-pin TSSOP (Thin Shrink Small Outline Package) type package, and is ideal for consumer system applications such as home appliances, cameras, and other electronic gadgets. It operates at a wide temperature range from -40°C to +85°C, and is ideal for applications with extremely wide operating temperatures. The BR24T128FVT-WE2 also provides a robust Write-protection feature that can prevent accidental data change in certain applications. This part also supports system sleep mode and wakeup mode, and offers a low power operation of 0.4mA when idling.
