L24W04/08 4K/8K 2-Wire (512x8/1,024x8) 3V~5.5V CMOS Serial EEPROM PRELIMINARY A z z z z z z z z z Automatic erase-before-write operation Partial page write allowed 16-byte Page Write Mode Write operation with built-in timer Hardware controlled write protection 40-year data retention 1,000,000 (106)rewrite cycles per word Commercial temperature range (0°C to +70°C) 8-pin SOP/DIP/TSSOP package General Description The L24W04/08 is a 4K/8K-bit serial read/write non-volatile memory device using the CMOS floating gate process. Its 4,096/8,192 bits of memory are organized into 512/1,024 words and each word is 8 bits. The device is optimized for use in many industrial and commercial Block Diagram applications where low power and low voltage operation are essential. Up to two L24W04/08 devices may be connected to the same 2-wire bus. The L24W04/08 is guaranteed for 1,000,000 (106) erase/write cycles and 40-year data retention.
