Devices Have Lowest Operating Voltage of Any SPD EEPROM in Industry
CHANDLER, Ariz., March 17, 2008 [NASDAQ: MCHP] Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced a series of Serial Presence Detect (SPD) EEPROM devices that support the latest Double Data Rate 2 (DDR2) DIMM modules used in today's high-speed PCs, as well as future DDR3 DIMM modules. The 34AA02, 34LC02 and 34VL02 (34XX02) devices meet the latest JEDEC standard for SPD EEPROM devices, with the 34VL02 supporting the lowest operating voltage range of any SPD EEPROM in the industry (1.5 to 3.6V). All the EEPROMs are available in JEDEC-standard packages and are the only SPD EEPROMs available in the popular 6-pin SOT-23 package.
