25LC080BT-I/MS

Overview

The Microchip Technology 25LC080BT-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 32-byte page size and offers block write protection capabilities. The component is housed in an 8-lead MSOP package and is rated for industrial temperature ranges from -40 °C to +85 °C.

Feature Summary

• Supports high-speed synchronous serial communication via a standard 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 power-on data protection circuitry.

Applications

• Data storage in microcontroller-based systems requiring non-volatile memory
• Configuration parameter retention in industrial control devices
• Calibration data logging in sensor interfaces

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the 'B' version designation aligns with the intended 32-byte page size requirement rather than the 16-byte variant. Ensure the voltage supply meets the minimum threshold for reliable operation at the target clock speed.

Selection Notes

Select this component when a compact surface-mount solution is required for small-capacity non-volatile storage. The MSOP package provides space efficiency compared to through-hole alternatives. Consider the 32-byte page buffer for applications prioritizing write throughput over byte-level granularity.

Part Context

This part belongs to the 25LC080A/B family of 8 Kbit SPI EEPROMs. The 'B' suffix indicates a 32-byte page size, distinguishing it from the 'A' version which uses a 16-byte page. The 'I' suffix denotes the industrial temperature rating, while 'MS' specifies the 8-lead Micro Small Outline Package.

Replacement Considerations

Public confirmed substitute part numbers: 25LC080BT-I/ST, 25LC080BT-E/MS, 25AA080BT-I/MS.
