25AA080CT-I/MNY

Memory IC Overview

The Microchip Technology 25AA080CT-I/MNY is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It utilizes a standard SPI-compatible serial bus interface with SCK, SI, SO, and CS signals. The device supports a maximum clock frequency of 10 MHz at supply voltages between 4.5 V and 5.5 V, scaling down to 3 MHz at 1.8 V to 2.5 V. Operating voltage ranges from 1.8 V to 5.5 V. It employs a 16-byte page size for write operations and includes a HOLD pin for communication pausing. The component is housed in an 8-lead TDFN package and operates within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed synchronous serial communication via a four-wire SPI compatible interface.
• Includes a dedicated hold input pin that suspends data transmission without resetting the internal address pointer.
• Features programmable block write protection allowing selective array security through status register configuration.
• Integrates built-in power-on/off data protection circuitry and a write enable latch mechanism.

Memory IC Applications

• Data logging systems requiring non-volatile storage for sensor readings
• Configuration memory for microcontroller-based embedded control systems
• Parameter storage in industrial instrumentation devices

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when ordering. Confirm the 'I' designation matches the required industrial temperature range for your application environment. Ensure the voltage supply aligns with the 1.8V to 5.5V operational limits specified for this variant. Cross-reference the datasheet revision to confirm pinout compatibility if replacing existing designs.

Memory IC Selection Notes

Select this component for applications requiring low-power CMOS technology and robust data retention capabilities. The 16-byte page size suits moderate throughput requirements where frequent small writes are not critical. Consider the TDFN package constraints regarding thermal dissipation and PCB space. Verify that the host microcontroller supports the necessary SPI modes and voltage levels for reliable communication.

Memory IC Part Context

This part belongs to the 25XX080C/D family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. The 'AA' prefix denotes support for lower voltage operation starting at 1.8 V, distinguishing it from the 'LC' series which requires a minimum of 2.5 V. The 'C' suffix identifies the 16-byte page size architecture, whereas 'D' variants utilize a 32-byte page structure.
