25AA080DT-I/MS

Memory IC Overview

The Microchip Technology 25AA080DT-I/MS is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM featuring SPI-compatible communication. It operates within a supply voltage range of 1.8V to 5.5V and supports maximum clock frequencies up to 10 MHz at 5.5V, 5 MHz at 2.5V, and 3 MHz at 1.8V. The device utilizes a 32-byte page size for write operations and includes a Hold pin for serial sequence suspension. It offers industrial temperature coverage from -40°C to +85°C in an 8-lead MSOP package.

Memory IC Feature Summary

• Supports high-speed SPI communication with a dedicated Hold pin to pause data transmission without resetting the sequence.
• Includes programmable block write protection allowing selection of none, one-quarter, one-half, or all array segments.
• Features built-in power-on/off data protection circuitry and a write enable latch to prevent inadvertent writes.
• Provides self-timed erase and write cycles with hardware write-protect capabilities via the WP pin.

Memory IC Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage

Memory IC Procurement Notes

Verify the specific suffix 'DT' indicates tape and reel packaging when ordering. Confirm the 'I' designation matches the required industrial temperature range of -40°C to +85°C. Ensure the 1.8V minimum operating voltage aligns with the target system's power rails. Check for RoHS compliance status as per the latest manufacturer documentation.

Memory IC Selection Notes

Select this component for applications requiring low-voltage operation down to 1.8V with SPI interface compatibility. Consider the 32-byte page size for efficient bulk data writing compared to older 16-byte variants. Evaluate the MSOP package dimensions against available PCB space constraints. Verify that the 10 MHz maximum clock speed meets the system's timing requirements.

Memory IC Part Context

This part belongs to the 25XX080C/D family of 8K SPI Serial EEPROMs. It shares functional similarities with the 25LC080 series but differs in its lower 1.8V operating voltage capability. The 'D' variant specifically denotes the 32-byte page size architecture, distinguishing it from the 16-byte 'C' version devices.
