25LC080C-I/MS

Overview

The Microchip Technology 25LC080C-I/MS is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM accessed via a SPI-compatible bus. It operates within a voltage range of 1.8V to 5.5V and supports clock frequencies up to 10 MHz at 5.5V. The device features a 16-byte page size, self-timed erase/write cycles with a maximum duration of 5 ms, and industrial temperature ratings from -40°C to +85°C. It utilizes an 8-lead MSOP package.

Feature Summary

• Supports serial communication via standard SPI interface with separate data in and out lines.
• Includes hardware write protection capabilities controlled by the WP pin and STATUS register bits.
• Features built-in power-on/off data protection circuitry and a write enable latch mechanism.

Applications

• Microcontroller system configuration storage
• Calibration parameter persistence
• Data logging for industrial sensors

Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C) and 'MS' denotes the 8-lead MSOP package. Confirm the 'C' variant specifies the 16-byte page size rather than the 32-byte 'D' version. Ensure the component meets RoHS compliance requirements for your assembly process.

Selection Notes

Select this component when a low-pin-count non-volatile memory solution is required for small data sets. It is suitable for applications needing frequent updates with moderate speed requirements. Consider the 16-byte page limit for write operations compared to larger page sizes available in other variants.

Part Context

This part belongs to the 25LC080C/D family of 8K SPI Bus Serial EEPROMs. It shares architectural similarities with the 25AA080C/D series but differs in minimum operating voltage specifications. The 'C' designation specifically identifies the 16-byte page buffer architecture within the broader 25XX080 product line.

Replacement Considerations

Direct functional substitutes include the 25LC080D-I/MS, which offers a 32-byte page size instead of 16 bytes. Other compatible packages within the same electrical specification include the TSSOP (ST) or SOIC (SN) variants, provided the physical footprint allows for adaptation.
