SPD EEPROMs support lowest operating voltage range

Chandler, Ariz.—Microchip Technology Inc. announced a series of Serial Presence Detect (SPD) EEPROMs that support the latest 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), according to Microchip.

These next-generation 34XX02 devices are designed to meet the JEDEC standard for newer DDR2 and future DDR3 modules, while also supporting the older DDR1 requirements. Because of their low operating-voltage ranges of 1.7 to 5.5V for the 34AA02; 2.5 to 5.5V for the 34LC02, and 1.5 to 3.6V for the 34VL02, the devices can be designed into current and future PCs that utilize low-voltage battery designs. All of the EEPROM devices are available in 8-pin TSSOP, 2 mm x 3 mm TDFN and MSOP packages, as well as a 6-pin SOT-23 package.

Pricing: In 100,000-unit quantities, the 34AA02 and 34LC02 devices are priced at $0.11 each for the TSSOP and SOT-23 packages; $0.12 each for the MSOP package, and $0.13 each for the TDFN package. Prices for the low-voltage 34VL02 devices are $0.10 higher in each of these packages—$0.21 each for the TSSOP and SOT-23 packages; $0.22 each for the MSOP package, and $0.23 each for the TDFN package.
