25AA080/P

Memory IC Overview

The Microchip Technology 25AA080/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 1.8 V to 5.5 V with a maximum clock frequency of 1 MHz. The device supports industrial temperature ranges from -40°C to +85°C and features SPI-compatible serial communication.

Memory IC Feature Summary

• Supports block write protection for none, one-quarter, one-half, or all array segments
• Includes built-in power-on/off data protection circuitry and a write enable latch
• Provides hardware write protection via the WP pin controlled by the Status register

Memory IC Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the component status as this part may be designated as not recommended for new designs. Ensure compatibility with existing PCB footprints and verify supply chain availability through authorized channels before finalizing procurement plans.

Memory IC Selection Notes

Select this component when low-voltage operation starting at 1.8 V is required alongside standard SPI interface compatibility. Consider the PDIP package for through-hole mounting requirements. Evaluate alternative models within the same family if higher clock speeds or surface-mount packaging options are necessary for the target application design.

Memory IC Part Context

This device belongs to the 25XX080 family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 25LC080 and 25C080 variants, differing primarily in minimum operating voltage and supported clock frequencies. The product line utilizes low-power CMOS technology for efficient energy consumption during read and standby operations.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 25AA080A/B and 25LC080A/B.
