25LC080C-E/P

Overview

The Microchip Technology 25LC080C-E/P 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 SPI-compatible serial communication and includes a 16-byte page size. It supports industrial temperature ranges from -40°C to +85°C and automotive ranges up to +125°C. Key electrical characteristics include a maximum write current of 5 mA at 5.5V, standby current of 5 µA, and data retention exceeding 200 years.

Feature Summary

• Supports block-level write protection for none, one-quarter, one-half, or all array segments via status register configuration.
• Includes built-in power-on/off data protection circuitry and a write enable latch to prevent inadvertent writes.
• Features a hold pin that allows suspension of serial communication without resetting the sequence.

Applications

• Microcontroller system configuration storage
• Calibration parameter persistence
• Data logging in embedded systems

Procurement Notes

Verify the specific suffix 'E' indicates the Automotive temperature grade (-40°C to +125°C) rather than Industrial. Confirm the 'P' suffix corresponds to the 8-lead PDIP package. Ensure the 'C' designation matches the required 16-byte page size, as 'D' variants offer 32 bytes. Cross-reference the RoHS compliance status with current manufacturing notices.

Selection Notes

Select this component when an SPI EEPROM requires automotive-grade thermal stability alongside standard 8Kb capacity. The 16-byte page size suits applications with smaller data updates compared to 32-byte alternatives. Verify that the host microcontroller supports the required SPI modes and voltage levels within the 2.5V to 5.5V operating range.

Part Context

This part belongs to the 25LC080C/D family of 8 Kbit Serial EEPROMs. The 'LC' variant specifies a 2.5V minimum supply voltage, distinguishing it from 'AA' models which support lower voltages. The 'C' suffix defines the 16-byte page architecture, whereas 'D' denotes 32-byte pages. The 'E' suffix designates the extended automotive temperature range capability.
