Frequently Asked Questions
What clock speed does the 25LC1024-I/MF support on its SPI interface?
The 25LC1024-I/MF supports a maximum SPI clock frequency of 20 MHz, enabling fast data transfers suitable for time-critical embedded applications. This performance level is maintained across the full 2.5 V to 5.5 V supply range.
How long can data stored in the 25LC1024-I/MF be retained without power?
Microchip specifies a minimum data retention time of 200 years for the 25LC1024-I/MF, ensuring long-term reliability in applications such as calibration data storage, firmware parameter retention, and industrial configuration logging.
Which supply voltage range makes the 25LC1024-I/MF compatible with both 3.3 V and 5 V microcontrollers?
The 25LC1024-I/MF operates from 2.5 V to 5.5 V, making it directly compatible with 3.3 V and 5 V microcontroller systems without additional level-translation circuitry. The 1 Mbit (128K x 8) capacity and DFN-S-8 package further simplify board integration.
When is the 25LC1024-I/MF a practical upgrade over smaller 512 Kbit SPI EEPROMs?
When an application stores large lookup tables, firmware update images, or multi-channel data logs exceeding 64 KB, the 25LC1024-I/MF's 128K x 8 address space provides twice the capacity of 512 Kbit devices while maintaining the same SPI 4-wire interface and pin-compatible DFN-S-8 footprint.
