The memory is organized as 128 x 8 bits, and the single-wire protocol handles both data and clock on the same pin, so no dedicated SPI or I²C bus is needed. At 1.8V it works with low-voltage microcontrollers; at 5V it drops into existing 5V industrial designs. ## Industrial temperature grade in a SOT-23-3 footprint","metaTitle":"Microchip 11AA010T-I/TT 1Kbit EEPROM, Single Wire, SOT-23-3","metaDescription":"Microchip 11AA010T-I/TT 1Kbit EEPROM with Single Wire interface, 1.8V to 5.5V supply, -40°C to 85°C.
