The devices are organized in blocks of x8-bit memory and support the Serial Peripheral Interface (SPI) compatible serial bus architecture. Byte-level and page-level functions are supported. The bus signals required are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input. Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transitions on its inputs will be ignored, with the exception of Chip Select, allowing the host to service higher priority interrupts. The 25LCXXXA is available in a standard 8-lead SOIC package. The package is Pb-free and RoHS Compliant.

Any design in which the total operating time between 125°C and 150°C will be greater than 1,000 hours is not warranted without prior written approval from Microchip Technology Inc. † NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for an extended period of time may affect device reliability.
