25AA080T-I/SN

Memory IC Overview

The Microchip Technology 25AA080T-I/SN is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM. It utilizes a low-power CMOS technology with a supply voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 1 MHz in the industrial temperature range (-40°C to +85°C). The device features a 16-byte page write capability, self-timed erase/write cycles, and block write protection. It is packaged in an 8-lead SOIC (150 mil) format and supplied in tape and reel packaging.

Memory IC Feature Summary

• Supports SPI-compatible serial bus communication with separate data input and output lines.
• Includes built-in hardware write protection via a dedicated pin and software-configurable array segments.
• Features power-on/off data protection circuitry and a write enable latch to prevent inadvertent writes.

Memory IC Applications

• Microcontroller system memory for storing configuration parameters.
• Data logging applications requiring non-volatile storage.
• Industrial control systems operating within the industrial temperature range.

Memory IC Procurement Notes

Verify that the specific ordering suffix 'T' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the 'I' designation matches the necessary industrial temperature range specifications for the target application environment.

Memory IC Selection Notes

Select this component when a low-pin-count, non-volatile memory solution is needed for small data sets. Ensure the host microcontroller supports the required SPI interface timing constraints. Consider the 16-byte page size limitation when designing write algorithms to optimize performance.

Memory IC Part Context

This part belongs to the 25XX080 family of 8 Kbit Serial EEPROMs. It shares functional similarities with the 25LC080 and 25C080 variants but differs in minimum supply voltage requirements and package availability. The datasheet notes that this specific generation is not recommended for new designs.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 25AA080A/B or 25LC080A/B series devices as recommended by the manufacturer for new designs.
