Frequently Asked Questions
What is the maximum I2C clock frequency supported by the 24AA00T-I/OT, and how does that affect write throughput?
The 24AA00T-I/OT supports up to 400 kHz fast-mode I2C. With 8-bit byte transfers, this translates to roughly 50 kbps effective data rate. Its 16-byte capacity can be fully written in under 1 ms at that speed, making it suitable for frequent configuration updates in low-power MCU systems.
Which supply voltage range does the 24AA00T-I/OT support, and can it interface directly with 1.8V microcontrollers?
The 24AA00T-I/OT operates from 1.8V to 5.5V, so it interfaces directly with 1.8V microcontrollers without any level shifting. This wide voltage range accommodates 3.3V and 5V legacy systems as well, making it a versatile drop-in EEPROM for mixed-voltage designs with up to 43 specified electrical parameters.
How long does the 24AA00T-I/OT retain stored data, and what endurance cycle count does it guarantee?
Microchip guarantees a minimum data retention of 200 years for the 24AA00T-I/OT, with an endurance rating of 1,000,000 write/erase cycles per byte. This combination makes it reliable for storing factory calibration data or serial numbers that are rarely rewritten but must persist for the product's entire lifetime.
For a compact wearable PCB, how small is the 24AA00T-I/OT package footprint?
The 24AA00T-I/OT comes in a SOT-23-5 package with only 5 pins, one of the smallest standard SMD outlines available. The package body measures approximately 2.9 mm x 1.6 mm, allowing integration into wearable and portable designs where every square millimeter of PCB area matters.
