512 Kb I2C EEPROM Fits In SOIC

Announced as an industry first, the 24LC515 is a 512 Kb I2C serial EEPROM that fits into a standard eight-lead SOIC package. Users of the companyÕs current 256 Kb devices now have an upgrade path to higher-density EEPROMs while remaining in the same package. The 512 Kb device has a page-write capability of up to 64 bytes and performs random reads up to the 512 Kbit boundary and sequential reads within each of its 256 Kb blocks. Functional address lines allow up to four devices on the same bus, for up to 2 Mb total address space. Additional features include a clock rate of 400 kHz, an operating voltage of 1.8V to 5.5V, and a temperature range of -40¡C to 85¡C. Another version of, the 24FC515, operates at a bus speed of 1 MHz over the same temperature range. Price is $2.10 for the 24LC515 and $2.25 for the 24FC515, each/10,000.
