25AA080DT-I/MNY

Memory IC Overview

The Microchip Technology 25AA080DT-I/MNY is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It utilizes a Serial Peripheral Interface (SPI) compatible bus with a maximum clock frequency of 10 MHz. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports a 32-byte page size for write operations. It is housed in an 8-lead TDFN package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports serial communication via a standard SPI-compatible interface with separate data input and output lines.
• Includes programmable block write protection allowing selection of none, one-quarter, one-half, or all array segments.
• Features hardware-based power-on/off data protection circuitry combined with a write enable latch mechanism.

Memory IC Applications

• Data storage for configuration parameters in microcontroller systems
• Logging operational history or event records in embedded devices
• Storing calibration constants and device-specific identifiers

Memory IC Procurement Notes

Verify the specific suffix 'DT' corresponds to the TDFN-8 package and 'I' indicates the industrial temperature grade. Confirm that the 'MNY' designation aligns with the required reel packaging format. Ensure the design accounts for the 1.8V minimum operating voltage specified for the AA series variants.

Memory IC Selection Notes

Select this component when low-voltage operation down to 1.8V is required alongside high-density storage. The 32-byte page size offers efficient bulk writing compared to older 16-byte variants. Consider the TDFN package constraints regarding thermal dissipation and PCB space requirements during layout.

Memory IC Part Context

This part belongs to the 25XX080C/D family of 8 Kbit SPI EEPROMs. It shares architectural similarities with the 25LC080D but differs in supply voltage specifications. The 'D' variant specifically denotes the 32-byte page buffer capability, distinguishing it from the 16-byte 'C' version within the same memory density class.
