25AA080BT-I/ST

Memory IC Overview

The Microchip Technology 25AA080BT-I/ST is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It utilizes a standard SPI-compatible serial bus for data access, supporting clock frequencies up to 10 MHz. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. It is housed in an 8-lead TSSOP package with a 32-byte page size.

Memory IC Feature Summary

• Supports block write protection allowing selective array segment locking
• Includes built-in power-on/off data protection circuitry
• Features a hold pin to pause serial communication without resetting sequences

Memory IC Applications

• Microcontroller system data storage
• Industrial control parameter logging
• Embedded configuration memory retention

Memory IC Procurement Notes

Verify the specific suffix 'B' indicates the 32-byte page size variant rather than the 16-byte 'A' version. Confirm the 'I' designation matches the required industrial temperature range specifications. Ensure the ST package type aligns with the target PCB footprint requirements before finalizing procurement orders.

Memory IC Selection Notes

Select this component when low-power CMOS technology and high reliability are required for non-volatile data retention. Consider the hardware write-protect capabilities and self-timed erase/write cycles for robust application environments. Verify compatibility with existing SPI bus architectures and microcontroller families during the design phase.

Memory IC Part Context

This part belongs to the 25XX080A/B family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants with different voltage ranges and page sizes, designed for advanced low-power applications requiring reliable data storage across various industrial and commercial operating conditions.

Memory IC Replacement Considerations

Direct substitutes include other 25AA080 or 25LC080 variants within the same Microchip family, provided the page size and voltage specifications match the original design requirements.
