Frequently Asked Questions

How many write/erase cycles can the 93LC56B-I/MS endure before reliability degrades?

The 93LC56B-I/MS is rated for a minimum of 1,000,000 write/erase cycles per byte location, giving it strong endurance for applications that update configuration or calibration data frequently in industrial or consumer embedded systems.

What operating voltage range does the 93LC56B-I/MS support, and can it run from a 3.3 V system?

The 93LC56B-I/MS operates across a 2.5 V to 5.5 V supply range, making it fully compatible with both 3.3 V and 5 V logic systems. No level-shifting is required when interfacing with most modern 3.3 V microcontrollers.

For a wearable device with tight board space, how does the MSOP-8 package compare to a standard SOIC-8?

The 8-pin MSOP package measures approximately 3 mm x 3 mm with 0.65 mm pin pitch, significantly smaller than the 4.9 mm x 3.9 mm SOIC-8 body, making the 93LC56B-I/MS a better fit for miniaturized PCB designs.

When would a designer choose 93LC56B-I/MS over a larger EEPROM such as a 64 Kbit device?

The 93LC56B-I/MS is the right choice when storage needs are limited to 2 Kbits of configuration or trim data, minimizing cost and PCB area. Applications storing only a few dozen bytes of factory calibration values benefit from its smaller size and lower price.
