It operates from a single 1.7V to 5.5V supply, making it a drop-in for 1.8V, 3.3V, or 5V logic rails without a level shifter. The 400 kHz clock frequency matches the standard I²C fast-mode bus speed used by most microcontrollers. The extended temperature range also covers outdoor telecom cabinets and factory-floor sensors that see thermal cycling. It is ROHS3 compliant.","metaTitle":"Microchip 34AA02T-E/ST 2Kbit I2C EEPROM, 1.7V-5.5V, 8-TSSOP","metaDescription":"Microchip 34AA02T-E/ST 2Kbit I2C EEPROM, 900 ns access, 400 kHz clock, 1.7V-5.5V supply, -40°C to 125°C.
