This IC is a 2-wire serial E2PROM with temperature sensor which operates in 1.7 V to 3.6 V voltage ranges. This IC has the capacity of 4 K-bit and the organization of 2 pages × 256-word × 8-bit. Page write and sequential read are available.
This IC operates with the I2C-bus at 1.0 MHz maximum.
A substantial reduction in current consumption may be achieved by using the software programmed shutdown mode which can be set by the I2C-bus.
In addition, the SMBus timeout function is supported; therefore, this IC is optimal for SSDs that communicate over the SMBus.

Caution : This product is intended to use in general electronic devices such as consumer electronics, office equipment, and communications devices. Before using the product in medical equipment or automobile equipment including car audio, keyless entry and engine control unit, it is imperative to contact our sales representatives.
