25AA080DT-I/SN

Memory IC Overview

The Microchip Technology 25AA080DT-I/SN is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM accessed via a SPI-compatible serial bus. It operates within a supply voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10 MHz. The device features a 32-byte page size, self-timed erase/write cycles with a maximum duration of 5 ms, and industrial temperature coverage from -40°C to +85°C. It is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes programmable block write protection for data security
• Features built-in power-on/off data protection circuitry
• Provides hold functionality to pause serial transmission without resetting the sequence

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration memory for microcontroller-based devices
• Industrial control applications needing reliable parameter storage

Memory IC Procurement Notes

Verify that the specific suffix 'DT' corresponds to the tape-and-reel packaging format intended for your assembly process, as standard tube packaging may differ. Confirm the 'I' designation matches your required industrial temperature range specifications. Ensure the 'SN' package code aligns with your PCB footprint requirements for the 8-lead SOIC form factor before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a low-voltage operation down to 1.8V is required, distinguishing it from the 2.5V minimum 25LC080 variants. Choose the 'D' version specifically if your application necessitates a 32-byte page size for efficient bulk writing operations. Consider the SOIC package if surface-mount compatibility with standard reflow profiles is needed for your manufacturing line.

Memory IC Part Context

This part belongs to the 25XX080C/D family of 8K SPI Serial EEPROMs. It shares architectural similarities with the 25AA080C and 25LC080 series but differs in voltage thresholds and page buffer sizes. The 'DT' suffix indicates a specific reel packaging option, while 'SN' denotes the SOIC physical package type within the broader Microchip memory portfolio.

Memory IC Replacement Considerations

The 25AA080AT-I/SN serves as a direct functional replacement offering identical electrical characteristics and pinout compatibility. Verify that any substitute maintains the same 1.8V to 5.5V operating voltage range and 32-byte page structure to ensure seamless integration without firmware modifications.
