Frequently Asked Questions
What are the key electrical specifications of the 25LC256-I/SN EEPROM?
The 25LC256-I/SN offers 256 Kbit (32K x 8) storage density, operates at 2.5 V supply voltage, supports SPI clock frequencies up to 10 MHz, and guarantees a minimum of 1,000,000 write/erase cycles with at least 200 years of data retention.
How does the 25LC256-I/SN perform in high-endurance data logging applications?
With 1,000,000 write/erase cycle endurance and 200-year data retention, the 25LC256-I/SN handles frequent updates in data logging and event counter applications. Its 10 MHz SPI clock allows rapid page writes across 32K x 8 memory, minimizing write latency in embedded systems.
Which embedded designs benefit from the SOIC-8 package of the 25LC256-I/SN?
The SOIC-8 package of the 25LC256-I/SN fits compact PCB layouts in wearables, industrial sensors, and IoT gateways where board space is limited. Its 8-pin surface-mount form factor with 2.5 V operation reduces power consumption compared to larger DIP alternatives.
When should designers choose the 25LC256-I/SN over higher-density SPI EEPROMs?
The 25LC256-I/SN is the right choice when 256 Kbit storage (32K x 8) is sufficient for parameter and configuration data, as it delivers 10 MHz SPI speed and 1,000,000 endurance cycles at a lower cost than 512 Kbit or 1 Mbit alternatives in the same SOIC-8 footprint.
