25LC080/SN

Overview

The Microchip Technology 25LC080/SN is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM. It features a 16-byte page write capability and operates within a voltage range of 2.5V to 5.5V. The device supports SPI-compatible serial bus communication with a maximum clock frequency of 2 MHz at VCC = 2.5V to 4.5V, scaling up to 3 MHz at VCC = 4.5V to 5.5V. It utilizes an 8-pin SOIC package and includes self-timed erase and write cycles with a maximum cycle time of 5 ms.

Feature Summary

• Supports block write protection allowing selection of none, 1/4, 1/2, or all array segments.
• Includes built-in power-on/off data protection circuitry and a write enable latch.
• Features a hold pin to pause serial transmission without resetting the sequence.

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage

Procurement Notes

Verify the specific suffix for temperature grade and packaging format against the datasheet. Confirm that the design complies with the manufacturer's recommendation to use newer alternatives like the 25LC080A/B series for new designs. Ensure voltage levels match the 2.5V to 5.5V operational range specified for the 25LC080 variant.

Selection Notes

Select this component for applications requiring low-power CMOS technology with typical standby current of 500 nA. Consider the 8-pin SOIC package for surface mount assembly. Verify that the required clock speed aligns with the voltage supply, as frequencies vary between 1 MHz and 3 MHz depending on VCC.

Part Context

This part belongs to the 25XX080 family of 8 Kbit Serial EEPROMs from Microchip Technology. The family includes variants such as the 25AA080 and 25C080, which differ in minimum operating voltage and maximum clock frequency specifications. The 25LC080 specifically targets industrial applications with a defined temperature range.
