Frequently Asked Questions
How fast is the 3-wire serial interface on the 93LC56A-I/SN, and is it compatible with standard SPI microcontroller peripherals?
The 93LC56A-I/SN supports a maximum clock frequency of 2 MHz on its 3-wire serial interface, which is compatible with the SPI mode of most microcontrollers. This speed is sufficient for reading and writing 2 Kbit of configuration or calibration data in typical embedded applications.
For designs with frequent NVM writes, how many write cycles does the 93LC56A-I/SN support before reliability degrades?
The 93LC56A-I/SN is rated for a minimum of 1,000,000 erase/write cycles per address, with a data retention specification exceeding 200 years. Designers using high-frequency writes should track cycle counts per memory location and implement wear-leveling if needed.
What supply voltage range does the 93LC56A-I/SN support, and can it operate in 3.3V systems?
The 93LC56A-I/SN is designed to operate across a wide supply voltage range that includes 3.3V systems, making it compatible with modern low-voltage microcontrollers without additional level-shift circuitry in most standard designs.
What should buyers know about lead times and stock planning for the 93LC56A-I/SN?
The 93LC56A-I/SN has a factory lead time of approximately 12 weeks. For production builds with steady demand, buyers should establish blanket orders or maintain 2–3 months of safety stock in the SOIC-8 package to avoid line stoppages.
