Catalyst Semiconductor has announced a Serial Presence Detect (SPD) EEPROM that supports Double Date Rate II (DDR II) memory modules.

Built around the JEDEC DDR II standard that defines reversible software write protect (RSWP) and permanent software write protect (PSWP) methods for the first 128B of the SPD EEPROM, the CAT34RC02 supports RSWP and PSWP methods. It features a permanent and reversible software memory-write protection, hardware write protection pin, a power supply operation range of 1.7V to 5.5V and an I?C data bus of 400kHz at 2.5V and 100kHz at 1.7V.

Offered in 8-lead TSSOP, SOIC and thin TDFN packages, product pricing starts at 25 cents in 10,000-piece quantities.
