25LC080AT-E/SN

Overview

The Microchip Technology 25LC080AT-E/SN is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It utilizes a standard SPI-compatible serial bus with SCK, SI, SO, and CS signals for communication. The device supports a maximum clock frequency of 10 MHz and operates within a supply voltage range of 2.5V to 5.5V. It includes a 16-byte page write buffer and self-timed erase/write cycles with a maximum duration of 5 ms. The component is housed in an 8-lead SOIC package and is rated for automotive temperature ranges from -40°C to +125°C.

Feature Summary

• Supports high-speed synchronous serial communication via a four-wire SPI compatible interface.
• Includes programmable block write protection allowing 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.

Applications

• Data storage in automotive electronic control units
• Configuration memory for industrial microcontroller systems
• Parameter logging in embedded sensor networks

Procurement Notes

Verify that the specific suffix 'T' corresponds to the required tape and reel packaging configuration as defined by the manufacturer's ordering guide. Confirm the 'E' designation aligns with the specified automotive temperature grade requirements for your target application environment.

Selection Notes

Select this part when an 8 Kbit non-volatile memory solution is required for automotive environments operating up to 125°C. Ensure the system design accommodates the 2.5V to 5.5V supply voltage range and utilizes an SPI master capable of supporting the 10 MHz clock frequency.

Part Context

This component belongs to the 25LC080A/B family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 25AA080 series but differs in minimum operating voltage specifications. The device is designed for direct interfacing with popular microcontroller families utilizing standard synchronous serial protocols.
