25LC080AT-I/MS

Overview

The Microchip Technology 25LC080AT-I/MS 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 and operates within a supply voltage range of 2.5 V to 5.5 V. It includes a 16-byte page write buffer and offers block write protection capabilities. The component provides high reliability with over 1,000,000 erase/write cycles and data retention exceeding 200 years.

Feature Summary

• Supports sequential read operations and self-timed erase/write cycles via SPI interface
• Includes built-in hardware and software write protection mechanisms such as the Write Enable Latch and WP pin
• Features a HOLD input to pause serial communication without resetting the sequence
• Compliant with RoHS standards and available in lead-free packaging

Applications

• Data storage in microcontroller-based systems requiring non-volatile memory
• Configuration parameter storage in industrial control applications
• Calibration data retention in embedded sensor networks
• Firmware or code storage in low-power consumer electronics

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the 'A' version designation aligns with the 16-byte page size requirement rather than the 32-byte variant. Ensure the voltage range specifications meet the system's power supply constraints before finalizing procurement orders.

Selection Notes

Select this component when a compact surface-mount solution is required for small-scale non-volatile data logging. The MSOP package is suitable for space-constrained designs. Consider the 2.5 V minimum operating voltage to ensure compatibility with the target system's logic levels and power rails during selection.

Part Context

This part belongs to the 25LC080A/B family of 8 Kbit Serial EEPROMs from Microchip Technology. It shares functional similarities with the 25AA080A series but differs in its minimum operating voltage requirements. The device is designed to interface directly with popular microcontroller families utilizing synchronous serial ports.

Replacement Considerations
