25LC080DT-I/SN

Overview

The Microchip Technology 25LC080DT-I/SN is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It utilizes a standard SPI-compatible serial bus with SCK, SI, SO, and CS signals for communication. The device supports a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. It operates within a supply voltage range of 2.5V to 5.5V and includes a HOLD pin to pause transmission without resetting the sequence. The component is housed in an 8-lead SOIC package.

Feature Summary

• Supports sequential read operations with automatic address pointer incrementation across the memory array.
• Includes built-in write protection mechanisms such as a write enable latch, power-on/off data protection, and a dedicated write-protect pin.
• Features block write protection allowing users to protect none, one-quarter, one-half, or all of the memory array via status register configuration.
• Provides a hold function that suspends serial communication while maintaining the current state, enabling host interruption handling.

Applications

• Data storage in microcontroller systems requiring non-volatile memory retention
• Configuration parameter storage in industrial control devices
• Calibration data logging in automotive electronic modules

Procurement Notes

Verify the specific suffix 'DT' against official Microchip documentation to confirm if it denotes a distinct tape-and-reel variant or packaging specification compared to standard 'D' designations. Ensure the 'I' temperature grade matches the intended operational environment limits. Confirm RoHS compliance status through the manufacturer's latest environmental declarations prior to final procurement decisions.

Selection Notes

Select this component when an 8 Kbit capacity with SPI interface is required for applications needing high reliability and long data retention. Consider the Industrial temperature range (-40°C to +85°C) for general purpose electronics. Evaluate the 32-byte page size capability for efficient bulk data writing operations compared to byte-only write alternatives.

Part Context

This part belongs to the 25XX080C/D family of 8K SPI Bus Serial EEPROMs from Microchip Technology. The family shares common electrical characteristics and instruction sets, differing primarily in voltage ranges (AA vs LC), page sizes (C vs D versions), and temperature grades. The 'SN' suffix indicates an 8-lead Small Outline Integrated Circuit package.
