25LC080BT-E/MS

Overview

The Microchip Technology 25LC080BT-E/MS is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It utilizes a standard SPI-compatible serial bus for communication, requiring SCK, SI, SO, and CS signals. The device supports a maximum clock frequency of 10 MHz and operates within a supply voltage range of 2.5V to 5.5V. It includes a 32-byte page write buffer and offers block write protection capabilities. The component is housed in an 8-lead MSOP package and is rated for an extended temperature range from -40°C to +125°C.

Feature Summary

• Supports high-speed synchronous serial communication via a standard four-wire SPI interface.
• Includes programmable hardware write protection controlled by the WP pin and Status Register bits.
• Features self-timed erase and write cycles with automatic latch reset upon completion.
• Provides data retention exceeding 200 years and endurance up to one million erase/write cycles.

Applications

• Data storage for configuration parameters in microcontroller-based systems
• Logging operational history or event records in industrial equipment
• Storing calibration constants and device identifiers in consumer electronics

Procurement Notes

Verify that the specific suffix 'BT' corresponds to the Automotive grade (-E) temperature rating and MSOP packaging as defined in the official datasheet. Confirm compatibility with system voltage levels, as the device requires a minimum of 2.5V. Ensure the design accounts for the 32-byte page size limitation during write operations to prevent data corruption at page boundaries.

Selection Notes

Select this component when an SPI interface is required for non-volatile memory with automotive-grade temperature stability. The 8Kbit capacity suits applications needing moderate storage for settings or logs. Consider the MSOP package dimensions if board space is constrained. Verify that the host controller can support the necessary SPI clock speeds and provides adequate voltage levels for reliable operation across the specified temperature range.

Part Context

This part belongs to the 25LC080 family of Serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with other devices in the series but is distinguished by its specific temperature rating and package type. The 'B' designation indicates a 32-byte page size, differentiating it from 'A' version devices which utilize a 16-byte page size.
