400 Khz 2-wire Serial E 2 Prom Inc.

The X24641 is a CMOS Serial E2PROM Memory, internally organized 8K x 8. The device features a serial Interface and software protocol allowing opera- tion on a simple two wire bus. The bus operates at 400KHz all the way down to 1.8V. Three device select inputs (S0S2) allow up to eight devices to share a common two wire bus. Hardware Write Protection is provided through a Write Protect (WP) input pin on the X24641. When the WP pin is HIGH, the upper quadrant of the Serial E2PROM array is protected against any nonvolatile write attempts. Xicor Serial E2PROM Memories are designed and tested for applications requiring extended endurance. Inherent data retention is greater than 100 years. By Intersil Corporation
