Frequently Asked Questions
How does the 25LC020AT-I/OT's 1,000,000 write cycle endurance affect its suitability for data logging applications?
With 1,000,000 write/erase cycles guaranteed, the 25LC020AT-I/OT can sustain a logging rate of roughly 1 write per minute for nearly 2 years before approaching the endurance limit on a single address. For most configuration-storage or infrequent calibration-update use cases, the device will outlast the product lifetime by many years, making wear-leveling unnecessary in typical embedded deployments.
What SPI clock speed does the 25LC020AT-I/OT support and how does that compare to typical microcontroller SPI peripherals?
The 25LC020AT-I/OT supports a maximum SPI clock frequency of 10 MHz, which is compatible with most 8-bit and 32-bit microcontroller SPI peripherals running at 4 MHz to 48 MHz system clocks. Reading or writing the full 256-byte array at 10 MHz takes under 300 µs, ensuring negligible overhead in real-time embedded firmware loops.
For a compact wearable PCB, how does the 6-pin SOT-23 package of the 25LC020AT-I/OT compare to 8-pin SOIC alternatives?
The 6-pin SOT-23 package occupies approximately 3 mm² of board area versus 29 mm² for a standard 8-pin SOIC, a reduction of over 90%. At a 2.5 V supply, only 3 passive components — two decoupling capacitors and a pull-up resistor — are needed, so the total solution footprint on a wearable PCB remains under 10 mm², enabling extremely compact non-volatile memory integration.
