25AA080A-I/P

Memory IC Overview

The Microchip Technology 25AA080A-I/P is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization and a 16-byte page size. It utilizes a standard SPI-compatible serial bus for communication, supporting clock frequencies up to 10 MHz. The device operates within a supply voltage range of 1.8 V to 5.5 V and is housed in an 8-lead PDIP package. Designed for industrial applications, it functions reliably across temperatures from -40 °C to +85 °C.

Memory IC Feature Summary

• Supports high-speed SPI communication with a maximum clock frequency of 10 MHz
• Includes programmable block write protection for selective array security
• Features built-in power-on/off data protection and a write enable latch mechanism
• Provides a hold function to pause serial transmission without resetting the sequence

Memory IC Applications

• Data storage for microcontroller systems via SPI interface
• Configuration parameter retention in embedded devices
• Calibration value storage requiring long-term data retention
• Industrial control system memory modules

Memory IC Procurement Notes

Verify that the specific part number suffix matches the required voltage range and temperature grade. Confirm the package type corresponds to the intended PCB layout. Ensure compliance with RoHS standards if applicable to the manufacturing process. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement.

Memory IC Selection Notes

Select this component when an 8 Kbit capacity with SPI interface is required. Choose the 'AA' variant specifically for low-voltage operation starting at 1.8 V. Opt for the 'I' temperature grade for standard industrial environments. Consider the PDIP package only if through-hole mounting is necessary for the mechanical design constraints.

Memory IC Part Context

This device belongs to the 25XX080A/B family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with other members like the 25LC080A but differs in minimum operating voltage specifications. The 'A' designation indicates a 16-byte page size, distinguishing it from the 'B' version which offers a 32-byte page size.

Memory IC Replacement Considerations

Direct substitutes include the 25LC080A-I/P for higher voltage applications and the 25AA080B-I/P for increased page size. Verify compatibility with existing firmware regarding instruction sets and timing parameters when switching between these variants.
