25LC080CT-H/SN

Overview

The Microchip Technology 25LC080CT-H/SN is an 8Kb (1,024 x 8) Serial Electrically Erasable PROM (EEPROM). It supports the SPI compatible serial bus architecture with a maximum clock frequency of 5 MHz. The device operates within a supply voltage range of 2.5V to 5.5V and features extended temperature support from -40°C to +150°C. It utilizes an 8-Lead SOIC package.

Feature Summary

• Supports byte-level and page-level write operations with self-timed erase and write cycles.
• Includes built-in hardware write protection via the WP pin and software block protection for none, 1/4, 1/2, or all of the array.
• Features power-on/off data protection circuitry and a write enable latch to prevent inadvertent writes.

Applications

• Microcontroller systems requiring non-volatile data storage
• Industrial applications operating at high temperatures
• Automotive electronics requiring AEC-Q100 qualification

Procurement Notes

Verify that the specific suffix 'H' corresponds to the Extended Temperature Range (-40°C to +150°C) as defined in the official datasheet. Confirm the 'SN' designation matches the 8-Lead SOIC package dimensions. Ensure the ordering code aligns with the manufacturer's current product line status.

Selection Notes

Select this component when high-temperature operation up to +150°C is required. The 8Kb capacity suits small data logging tasks. Verify system voltage compatibility within the 2.5V to 5.5V range. Consider the 5 MHz speed limit if higher throughput is needed.

Part Context

This part belongs to the 25LCXXX family of mid-density serial EEPROMs. It shares architectural similarities with other densities like 16Kb and 32Kb variants but offers specific 8Kb organization. The 'H' suffix denotes the extended temperature grade distinct from standard industrial grades.

FAQ

What is the maximum clock frequency for this device?

The maximum clock frequency is 5 MHz.

How does the Write Protect (WP) pin function?

When the WP pin is low and the WPEN bit is high, writing to the nonvolatile bits in the STATUS register is disabled, while other operations function normally.
