Frequently Asked Questions
What endurance and data retention does the 93LC56/SN EEPROM offer for mission-critical logging applications?
The 93LC56/SN is rated for up to 1,000,000 write/erase cycles and a minimum data retention time of 200 years. These specifications make it suitable for storing frequently updated configuration data, event counters, or calibration values in industrial and consumer applications without risk of data loss.
Which supply voltage range does the 93LC56/SN support, and how does that affect microcontroller selection?
The 93LC56/SN operates from 2.5 V to 5.5 V, covering both 3.3 V and 5 V microcontroller domains. This wide range eliminates the need for a level-shifting buffer when connecting to popular 8-bit or 32-bit MCUs, reducing BOM cost and simplifying PCB layout in compact embedded designs.
How does the 93LC56/SN 8-pin SOIC package compare in board area to an equivalent PDIP variant?
The 8-pin SOIC package occupies roughly 19 mm² of PCB area versus approximately 65 mm² for an 8-pin PDIP, saving significant board space in surface-mount designs. The SOIC-8 footprint also supports automated pick-and-place assembly at standard reflow temperatures, improving throughput in high-volume production.
At what maximum clock frequency can the 93LC56/SN be driven over its 3-wire serial interface?
The 93LC56/SN supports a maximum clock frequency of 2 MHz on its 3-wire serial interface. This speed is sufficient for low-data-rate storage tasks such as writing 16-byte configuration blocks or reading a 2 Kbit EEPROM array in under 1 ms at full clock rate.
