Microchip’s Serial EEPROM products are compatible with four serial bus types and support densities that range from 128 bits up to 1 Mbits. These bus types include the standard two wire I2C, three-wire Microwire, four wire SPI and the new single I/O, UNI/O® bus. As Microchip’s EEPROMs are compatible with the de facto industry standards, they can be used as drop-in replacements for competitor devices in most cases. By supporting a wide operating voltage range from 1.7 volts up to 5.5 volts and a wide temperature range from -40°C to 125°C almost all applications are supported. For new designs, Microchip’s value-added features include smaller footprints, lower power consumption, lower voltage levels (down to 1.5V), faster bus rates and higher endurance levels help ensure truly robust designs of the highest quality.
Microchip has been at the forefront of Serial EEPROM innovation – Along with ensuring highest quality products, today we offer a new family of single I/O UNI/O® EEPROM devices, the lowest voltage EEPROMs at 1.5V, the fastest bus speed on the SPI at 20 MHz and provide the industry’s lowest operating current which ensures lower power consumption. Microchip also recently launched a family of MAC address chips each of which are pre-programmed with unique EUI-48™ and EUI-64™ node addresses.
