25LC080C-E/SN

Overview

The Microchip Technology 25LC080C-E/SN is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It operates on a 2.5V to 5.5V supply voltage with a maximum clock frequency of 10 MHz. The device utilizes an SPI-compatible serial bus for communication and includes a 16-byte page size. It supports industrial temperature ranges from -40°C to +125°C and is housed in an 8-lead SOIC package.

Feature Summary

• Supports high-speed SPI communication with a maximum clock frequency of 10 MHz.
• Includes built-in write protection mechanisms such as a write enable latch, power-on/off data protection, and a dedicated write-protect pin.
• Features block write protection allowing selection of none, 1/4, 1/2, or all array segments.
• Provides high reliability with over 1 million erase/write cycles endurance and greater than 200 years data retention.

Applications

• Microcontroller system memory storage
• Data logging applications
• Configuration parameter storage

Procurement Notes

Verify the specific suffix 'E' confirms the automotive temperature grade (-40°C to +125°C) and 'SN' denotes the 8-lead SOIC package. Confirm the 'C' variant specifies the 16-byte page size rather than the 32-byte page size found in 'D' variants. Ensure RoHS compliance requirements are met for the target assembly process.

Selection Notes

Select this component when an 8 Kbit non-volatile memory solution is required with SPI interface compatibility. The 'E' suffix indicates suitability for extended temperature environments up to +125°C. Choose this part over the 'AA' series if the minimum operating voltage requirement is 2.5V rather than 1.8V. Verify that the 16-byte page size aligns with the application's write buffer constraints.

Part Context

This device belongs to the 25XX080C/D family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 25AA080C but differs in its lower minimum operating voltage specification. The 'C' designation distinguishes it from the 'D' version, which offers a larger 32-byte page size for sequential write operations.

FAQ

How does the HOLD pin function during serial communication?

The HOLD pin allows the host to pause serial communication without resetting the sequence. When pulled low while SCK is low, inputs are ignored except Chip Select. Communication resumes when HOLD is brought high while SCK is low.

What happens if a page write crosses a physical page boundary?

If a page write attempts to cross a physical page boundary, the data wraps around to the beginning of the current page, overwriting previously stored data, instead of writing to the next page.
