Product details

8Kbit SPI EEPROM for parameter storage

The 25LC080B-I/SN is an 8Kbit serial EEPROM organized as 1K x 8 bytes, accessed over an SPI bus at clock rates up to 10 MHz. Non-volatile storage retains calibration coefficients, device configuration, or serialization data through power cycles — the 5 ms page write time means the host controller must manage the write cycle timing rather than issuing back-to-back commands.

Supplied in Tube packaging, not tape-and-reel — for volume pick-and-place runs, confirm the feeder setup accommodates tube-fed components or request a reeled variant from the same family.

ROHS3 Compliant per the manufacturer declaration, covering all ten restricted substances under EU RoHS recast without exemptions.

Frequently asked questions

What is the closest functional second-source for the 25LC080B-I/SN?

The AT24C08D-SSHM-B is an 8Kbit EEPROM in the same 8-SOIC package, but it uses an I²C interface instead of SPI — the bus protocol is different, so firmware and pin connections must change. The Microchip 23K640-I/SN shares the same SPI bus and package but is a 64Kbit SRAM (volatile), not an EEPROM.

What compliance documentation does Microchip provide for the 25LC080B-I/SN?

Microchip certifies the 25LC080B-I/SN as ROHS3 Compliant, covering all ten restricted substances under the EU RoHS recast. Standard documentation includes the RoHS certificate of compliance and the material declaration datasheet.
