25AA080AT-I/MS

Memory IC Overview

The Microchip Technology 25AA080AT-I/MS is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM featuring a 16-byte page size. It operates via a standard SPI-compatible serial bus with a maximum clock frequency of 10 MHz and supports a supply voltage range of 1.8 V to 5.5 V. The device utilizes low-power CMOS technology, offering high endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. It is housed in an 8-lead MSOP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports sequential read operations and self-timed erase/write cycles with a maximum write cycle time of 5 ms.
• Includes built-in hardware write protection mechanisms such as a write enable latch, power-on/off data protection circuitry, and a dedicated write-protect pin.
• Features a HOLD input that allows the host to pause serial communication without resetting the sequence, facilitating higher priority interrupt servicing.

Memory IC Applications

• Data storage for firmware parameters or configuration settings in microcontroller systems
• Non-volatile memory logging in industrial sensor networks
• Embedded system calibration data retention

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm the 'I' designation aligns with the required industrial temperature range specifications for your application environment. Ensure compatibility with the 1.8V minimum operating voltage if utilizing low-voltage logic interfaces.

Memory IC Selection Notes

Select this component for applications requiring robust non-volatile storage with hardware-level write protection features. The 16-byte page size is suitable for small data updates, while the 10 MHz SPI interface supports moderate-speed data transfers. Consider the MSOP package dimensions for space-constrained printed circuit board layouts.

Memory IC Part Context

This part belongs to the 25XX080A/B family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 25LC080 series but differs in its lower 1.8 V operating voltage capability. The device integrates directly with SPI ports found in popular microcontroller families.

Memory IC Replacement Considerations

Cross-reference with 25AA080A variants for identical electrical characteristics. Verify package compatibility when substituting with other 8-lead MSOP devices from different manufacturers.
