25LC080CT-I/ST

Overview

The Microchip Technology 25LC080CT-I/ST is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It operates via a SPI-compatible serial bus with a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. The device supports a supply voltage range of 1.8V to 5.5V and utilizes a 16-byte page write architecture. It is housed in an 8-lead TSSOP package and rated for industrial temperatures from -40°C to +85°C.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and 'ST' denotes the TSSOP package. Confirm the 'C' version designation aligns with the required 16-byte page size, as 'D' versions utilize 32-byte pages. Ensure the ordering suffix matches the exact pinout and physical dimensions specified in the datasheet packaging section.

Selection Notes

Select this component when a low-pin-count non-volatile memory solution is required for SPI-based systems. It is suitable for applications needing moderate endurance and long data retention within standard industrial operating conditions. Consider the 1.8V minimum supply capability if interfacing with lower voltage logic families.

Part Context

This part belongs to the 25XX080C/D family of 8K SPI Serial EEPROMs. The 'LC' variant indicates a 2.5V to 5.5V supply range, though the datasheet lists 1.8V to 5.5V for the Industrial grade. It shares architectural similarities with other members like the 25AA080 series but differs in voltage specifications and page sizes depending on the C or D suffix.

Replacement Considerations

Public confirmed substitute part numbers include 25LC080DT-I-MNY.
