Frequently Asked Questions
How does the UNI/O single-wire interface of 11AA02E48T-I/TT simplify PCB routing compared to I2C?
11AA02E48T-I/TT uses Microchip's UNI/O protocol, requiring only 1 data pin versus 2 pins for standard I2C, freeing a GPIO on the host MCU. The maximum clock frequency is 100 kHz, and the SOT-23-3 package has just 3 pins, making PCB routing straightforward in space-constrained wearable and IoT designs.
What data retention and endurance does 11AA02E48T-I/TT guarantee for industrial applications?
11AA02E48T-I/TT guarantees a minimum data retention time of 200 years and an endurance of 1,000,000 write/erase cycles per the datasheet specifications. These figures make it well suited for industrial sensors and meters that log calibration coefficients or event counters over multi-decade product lifetimes without data loss.
Can 11AA02E48T-I/TT operate directly with a 1.8V microcontroller without level shifting?
Yes. 11AA02E48T-I/TT is specified for 1.8V supply operation, matching the I/O levels of modern low-power microcontrollers such as those in the ARM Cortex-M0+ family running at 1.8V. No level-shifting circuitry is required, reducing BOM cost and simplifying the power architecture for battery-powered sensor nodes with 2Kbit non-volatile storage needs.
