25LC080A-I/SN

Overview

The Microchip Technology 25LC080A-I/SN is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It operates via a standard SPI-compatible serial bus with a maximum clock frequency of 10 MHz. The device supports a supply voltage range of 2.5 V to 5.5 V and utilizes a 16-byte page size for write operations. It is housed in an 8-lead SOIC package and functions within an industrial temperature range of -40 °C to +85 °C.

Feature Summary

• Supports high-speed synchronous serial communication via a standard SPI interface.
• Includes programmable block write protection to secure specific memory segments.
• Features built-in power-on/off data protection circuitry and a write enable latch.
• Provides hardware write protection capability through the dedicated WP pin.

Applications

• Data storage for configuration parameters in microcontroller systems
• Storing calibration constants and user-defined settings
• Logging operational data in industrial monitoring equipment

Procurement Notes

Verify that the ordering suffix matches the required package type, specifically SN for the SOIC variant. Confirm the temperature grade corresponds to the intended operating environment. Ensure the component version aligns with the specified voltage range and page size requirements for the target application design.

Selection Notes

Select this component when a low-pin-count non-volatile memory solution is required for small data sets. It is suitable for designs utilizing standard SPI peripherals on host processors. Consider the 16-byte page limitation during software implementation to ensure efficient write cycles without crossing physical page boundaries.

Part Context

This part belongs to the 25XX080A/B family of 8 Kbit EEPROMs manufactured by Microchip Technology. The 'LC' designation indicates a minimum operating voltage of 2.5 V, distinguishing it from the 'AA' series which supports lower voltages down to 1.8 V. The 'I' suffix denotes the industrial temperature rating.

Replacement Considerations

Direct functional substitutes within the same package include the 25LC080B-I/SN, which offers a 32-byte page size instead of 16 bytes. Other compatible variants include the 25AA080A-I/SN for applications requiring a wider voltage range starting at 1.8 V.
