25LC080B-I/MS

Overview

The Microchip Technology 25LC080B-I/MS is an 8 Kbit (1024 x 8) Serial Electrically Erasable PROM utilizing a standard SPI-compatible interface. It operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 10 MHz. The device features a 32-byte page write buffer, self-timed write cycles with a maximum duration of 5 ms, and industrial temperature ratings from -40 °C to +85 °C. Packaged in an 8-lead MSOP format, it provides high reliability with over 1,000,000 erase/write cycles and data retention exceeding 200 years.

Feature Summary

• Supports 32-byte page writes for efficient data storage operations
• Includes programmable block write protection for array security
• Features built-in power-on/off data protection circuitry

Applications

• Microcontroller system configuration storage
• Calibration parameter persistence
• Embedded application log caching

Procurement Notes

Verify the specific 'I' suffix confirms the Industrial temperature range (-40°C to +85°C). Confirm the 'B' designation ensures the 32-byte page size requirement. Ensure the MSOP package matches the target PCB footprint. Check current lifecycle status as older variants may be discontinued.

Selection Notes

Select this component when a 32-byte page size is required instead of the 16-byte variant. Verify that the 2.5 V minimum operating voltage aligns with the system power rails. Consider the MSOP package dimensions against available board space constraints.

Part Context

This part belongs to the 25LC080A/B family of serial EEPROMs. The 'B' version specifically increases the page size to 32 bytes compared to the 16-byte 'A' version. It shares the same pinout and instruction set as other devices in the series, facilitating direct software compatibility across capacity ranges.

Replacement Considerations

25LC080A-I/MS offers identical functionality but utilizes a 16-byte page size instead of 32 bytes.
