S-34TS04A 2 2-WIRE SERIAL E PROM WITH TEMPERATURE SENSOR www.ablic.com FOR DIMM SERIAL PRESENCE DETECT ABLIC Inc., 2013-2019 Rev.2.0 00 U 2 This IC is a 2-wire serial E PROM with temperature sensor for DIMM serial presence detect which operates in 2.2 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. 2 This IC operates with the I C-bus at 1.0 MHz maximum. A substantial reduction in current consumption may be achieved by using the software programmed shutdown mode which 2 can be set by the I C-bus. 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.
