Frequently Asked Questions
How many write cycles can the 25LC010A-I/SN withstand, and what data retention does it guarantee?
The 25LC010A-I/SN is rated for a minimum of 1,000,000 write/erase cycles per byte location, which far exceeds the demands of most configuration and calibration update scenarios. Data retention is guaranteed for a minimum of 200 years under normal storage conditions, providing reliable long-term non-volatile memory for industrial and consumer products.
What SPI clock speed does the 25LC010A-I/SN support across its full supply voltage range?
The 25LC010A-I/SN supports a maximum SPI clock frequency of 10 MHz when powered from 4.5 V to 5.5 V. When the supply drops to the 2.5 V to 4.5 V range, the maximum clock is 5 MHz. This dual-speed behavior allows the device to interface directly with both 3.3 V and 5 V microcontrollers without external clock conditioning.
Which applications benefit most from using the 25LC010A-I/SN as non-volatile storage?
Applications that store small amounts of configuration data—such as MAC addresses, calibration coefficients, or user settings—benefit from this 1 Kbit EEPROM. Its 128-byte capacity is sufficient for storing 8 to 16 calibration parameters at 8-bit or 16-bit resolution. IoT sensors, smart meters, and industrial transmitters commonly use this part to persist factory trim values across power cycles.
How does the 8-pin SOIC package of the 25LC010A-I/SN simplify PCB integration?
The SOIC-8 package has a 1.27 mm pin pitch and a body size of approximately 4.9 mm × 3.9 mm, making it easy to hand-solder or place by machine on standard PCB pads. This widely stocked package type is compatible with most PCB design rules at 0.1 mm or larger trace width, and the 8-pin count keeps the footprint under 20 mm², fitting even densely populated boards.
