Frequently Asked Questions
What is the maximum clock frequency supported by the 24LC16BHT-I/OT, and which I2C mode does that correspond to?
The 24LC16BHT-I/OT supports a maximum clock frequency of 400 kHz, corresponding to I2C Fast Mode. This allows rapid byte-write and sequential-read operations across 2 KB of non-volatile storage, making it suitable for applications that require frequent small data updates within a tight latency budget.
How many write cycles can the 24LC16BHT-I/OT endure before wear affects data reliability?
Microchip guarantees a minimum endurance of 1,000,000 write/erase cycles per memory location for the 24LC16BHT-I/OT. Combined with a 200-year data retention specification, this makes the device robust enough for logging applications that update stored values thousands of times per day over a multi-year product lifetime.
Can the 24LC16BHT-I/OT operate in a 3.3 V mixed-signal system alongside a 5 V microcontroller?
Yes. The 24LC16BHT-I/OT operates across a supply range of 2.5 V to 5.5 V, so it can be directly powered from a 3.3 V rail. When connected to 5 V logic, the I2C lines must use pull-up resistors referenced to the lower voltage rail or a level-shifting circuit to keep SDA and SCL within the device's 5.5 V absolute maximum input rating.
Which package does the 24LC16BHT-I/OT use, and what are its key PCB footprint dimensions?
The 24LC16BHT-I/OT is housed in a SOT-23-5 package with a 5-pin footprint measuring approximately 3.0 mm × 1.75 mm. This compact outline allows placement on densely populated boards such as wearable sensors, Bluetooth modules, and handheld instruments where board real estate is critically limited.
When is the 24LC16BHT-I/OT a better choice than a larger 24LC256 for an IoT node design?
For IoT sensor nodes that store only device configuration and calibration coefficients—typically under 2 KB—the 24LC16BHT-I/OT offers sufficient 16 Kbit capacity in a much smaller SOT-23-5 outline, reducing both BOM cost and PCB area compared to a 256 Kbit device. When data logging requirements grow beyond 2 KB or a page-write buffer larger than 16 bytes is needed, upgrading to the 24LC256 becomes warranted.
