25AA010A/S16K

Memory IC Overview

The Microchip Technology 25AA010A/S16K is a 1 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) utilizing an SPI-compatible serial bus. It features a 128 x 8-bit organization with a maximum clock frequency of 10 MHz and operates within a supply voltage range of 1.8V to 5.5V. The device supports sequential read operations and write page modes up to 16 bytes, with self-timed erase and write cycles completing in a maximum of 5 ms. It includes block write protection capabilities and built-in power-on/off data protection circuitry.

Memory IC Feature Summary

• Supports high-speed SPI communication with a maximum clock frequency of 10 MHz for efficient data transfer.
• Includes hardware write protection via the WP pin and software protection through the STATUS register block protection bits.
• Features a HOLD input that allows suspension of serial communication without resetting the sequence, facilitating host interrupt handling.

Memory IC Applications

• Microcontroller system configuration storage
• Calibration data retention
• Parameter logging in industrial sensors

Memory IC Procurement Notes

Verify the specific package suffix 'S16K' against official Microchip documentation to confirm it corresponds to the standard SOIC-8 form factor or a specialized variant. Confirm RoHS compliance status and temperature grade availability directly with the manufacturer or authorized distributors prior to ordering.

Memory IC Selection Notes

Select this component when a low-pin-count non-volatile memory solution is required for small data sets. Ensure the application environment stays within the -40°C to +85°C industrial temperature range. Verify that the system voltage remains compatible with the 1.8V to 5.5V operating range and that SPI bus timing constraints are met.

Memory IC Part Context

This part belongs to the 25XX010A family of 1 Kbit SPI EEPROMs from Microchip Technology. It shares functional similarities with the 25LC010A but differs in its lower minimum operating voltage specification. The series is designed for applications requiring reliable data retention and moderate write endurance in compact electronic devices.

Memory IC Replacement Considerations

The 25LC010A serves as a direct functional substitute within the same datasheet, though it requires a higher minimum supply voltage of 2.5V compared to the 1.8V minimum of the 25AA010A. Other capacity variants in the 25AA/25LC series require different addressing and may not fit physically identical footprints if package sizes differ.
