Frequently Asked Questions
How many write cycles can 24AA128T-I/MNY sustain and what data logging frequency does this support?
The 24AA128T-I/MNY is rated for a minimum of 1,000,000 write/erase cycles per byte location. At a data logging rate of 1 write per minute, this equates to over 1.9 years of continuous logging to a single memory address before wear-out, and far longer when writes are distributed across the full 128 Kbit (16,384 byte) address space using wear-leveling techniques.
What is the I2C clock frequency of 24AA128T-I/MNY and how quickly can it transfer a full 16 KB image?
The 24AA128T-I/MNY supports I2C Fast Mode at up to 400 kHz clock frequency. At 400 kHz with 8-bit data transfers and standard I2C overhead, a full 16 KB sequential read completes in approximately 330 ms, making it practical for firmware parameter loading at power-up in microcontroller-based systems operating at 3.3 V or 5 V.
Which supply voltage range does 24AA128T-I/MNY support and what battery or regulator configurations does it suit?
The 24AA128T-I/MNY operates from 1.7 V to 5.5 V, covering single-cell lithium primary batteries (3.6 V), regulated 1.8 V and 3.3 V rails from LDO regulators, and 5 V microcontroller systems. This wide range eliminates the need for a dedicated supply regulator, reducing BOM cost in battery-powered IoT devices by 1 or 2 components.
For a compact IoT sensor board, what board area does the 24AA128T-I/MNY TDFN-8 package require compared to an SOIC-8?
The 8-pin TDFN (Thin Dual Flat No-lead) package of the 24AA128T-I/MNY measures approximately 2 mm x 3 mm, occupying only 6 mm² of PCB area. In comparison, a standard SOIC-8 package requires roughly 30 mm² including lead lands. For designs targeting a total PCB area under 10 cm², this 80% area reduction makes the TDFN-8 the preferred choice for dense multi-sensor IoT boards.
