The 24VLXX, from Microchip, is a series of I2C EEPROM devices with 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. Each of the five 24VLXX 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.
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, the EEPROM devices are the first to support this low voltage level, and they are versatile enough to support two different write-protect features.
The low-voltage 24VL014, 24VL014H, 24VL024, 24VL024H, and 24VL025 devices provide another option for designers looking to maximize battery life in their applications. With an operating frequency of 100 kHz at 1.5V, the 24VLXX series EEPROMs 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 low-voltage DIMM modules in laptop computers, as well as wireless keyboards, mice, headsets and remote controls.
