25LC080/P

Overview

The Microchip Technology 25LC080/P is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM housed in an 8-lead Plastic Dual In-line Package (PDIP). It operates on a voltage range of 2.5V to 5.5V with a maximum clock frequency of 2 MHz. The device utilizes a standard SPI-compatible serial bus for communication, featuring low-power CMOS technology with typical standby current of 500 nA and read current of 500 µA. It supports self-timed erase and write cycles with a maximum cycle time of 5 ms.

Feature Summary

• Supports block write protection allowing selection of none, one-quarter, one-half, or all array segments.
• Includes built-in power-on/off data protection circuitry and a dedicated write-protect pin.
• Features sequential read capability with automatic internal address pointer incrementation.

Applications

• Microcontroller system memory storage
• Data logging applications
• Configuration parameter storage

Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. Confirm that the component meets RoHS compliance requirements for your assembly process. Check for any manufacturer change notifications regarding this legacy part number before finalizing procurement plans.

Selection Notes

Select this component when a through-hole PDIP package is required for prototyping or specific mechanical constraints. Ensure the system voltage remains within the 2.5V to 5.5V operating range. Verify that the 2 MHz clock speed is sufficient for the application's data throughput requirements.

Part Context

This device belongs to the 25XX080 family of 8 Kbit SPI Serial EEPROMs from Microchip Technology. It shares functional similarities with the 25AA080 and 25C080 variants, differing primarily in minimum operating voltage and package availability. The 'P' suffix specifically denotes the 8-lead PDIP package format.

Replacement Considerations

Microchip recommends using the 25LC080A/B series instead of this older generation part for new designs. Verify compatibility with updated datasheets if migrating to newer revisions within the same product family.
