25LC080D-I/SN

Overview

The Microchip Technology 25LC080D-I/SN is an 8 Kbit (1024 x 8) Serial Electrically Erasable PROM accessed via a SPI-compatible serial bus. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 10 MHz at 4.5 V to 5.5 V. The device features a 32-byte page size, self-timed erase/write cycles with a maximum duration of 5 ms, and industrial temperature operation from -40°C to +85°C. It is housed in an 8-lead SOIC package.

Feature Summary

• Supports block write protection for none, one-quarter, one-half, 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 communication without resetting the sequence

Applications

• Microcontroller system data storage
• Industrial control applications
• Consumer electronics memory backup

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the 'D' designation indicates the 32-byte page size variant rather than the 16-byte 'C' version. Ensure the 'I' suffix corresponds to the industrial temperature range requirements for your design environment.

Selection Notes

Select this component when an 8 Kbit non-volatile memory solution with SPI interface is required. The 'D' variant provides a larger 32-byte page buffer compared to the 'C' version. Verify that the operating voltage falls within the 2.5 V to 5.5 V range and that the environmental conditions align with the industrial temperature specifications.

Part Context

This part belongs to the 25XX080C/D family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants with different page sizes and voltage ranges, such as the 25AA080 series. The 25LC080D specifically denotes the low-voltage CMOS technology with a 32-byte page structure.

FAQ

What is the difference between the 25LC080C and 25LC080D versions?

The primary difference is the page size; the 25LC080C has a 16-byte page size, while the 25LC080D has a 32-byte page size.

How does the HOLD pin function during operation?

The HOLD pin allows the user to suspend transmission to the device mid-sequence without retransmitting the entire sequence. Transitions on SI, SCK, and SO are ignored while held low.
