MEMORY: Microchip claims lowest voltage I2C EEPROMs

Chandler, Ariz. – Microchip Technology has just announced a series of I2C EEPROM devices with what the company claims is the lowest operating voltage available on the market.

The 24VLXX series of devices has an operating voltage down to 1.5V for both Read and Write operations, with a very low operating current well below 400 microamperes.

As an added feature, the 24VL014, 24VL024 and 24VL025 can be ordered with a full-array write protect, while the 24VL014H and 24VL024H devices support a half-array write protect. In densities of 1K or 2 Kbits, these EEPROM devices are the first to support this low voltage level, and they are versatile enough to support two different write-protect features.

According to Randy Drwinga, vice president of Microchip's Memory Products Division, the new low-voltage devices feature an operating frequency of 100 kHz at 1.5V, and can operate in portable and handheld applications with very low voltages, thus reducing power consumption and extending the useful life of the battery. Examples include, he said, low-voltage DIMM modules in laptop computers, as well as wireless keyboards, mice, headsets and remote controls.

The devices are supported by the MPLAB Starter Kit for Serial Memory Products. The kit includes the MPLAB Starter Kit for serial memory products board, a serial EEPROM starter pack, a USB cable, and a CD containing the MPLAB IDE, Total Endurance software model and a serial EEPROM interface tool. It is available for $79.98.

The five low voltage EEPROM devices is available in an 8-pin SOIC, MSOP, PDIP and 2 mm x 3 mm TDFN package. The 24VL014 and 24VL014H devices are priced at $0.31 each for the SOIC package and up to $0.37 each for the TDFN package, in 10,000-unit quantities. The 24VL024, 24VL024H and 24VL025 devices are priced at $0.34 each for the SOIC package and up to $0.40 for the TDFN package, in 10,000-unit quantities. To learn more, go to www.microchip.com/VL.
