25LC080-I/P

Overview

The Microchip Technology 25LC080-I/P is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM. It utilizes a standard SPI-compatible serial bus interface requiring SCK, SI, SO, and CS signals. The device operates within a voltage range of 2.5 V to 5.5 V with a maximum clock frequency of 2 MHz in the Industrial temperature range (-40°C to +85°C). It features low-power CMOS technology with typical standby current of 500 nA and read current of 500 µA. The memory supports self-timed erase and write cycles with a maximum cycle time of 5 ms.

Feature Summary

• Supports block-level write protection allowing selection of none, one-quarter, one-half, or all array segments.
• Includes built-in power-on/off data protection circuitry and a write enable latch mechanism.
• Features a hold pin capability to pause serial communication without resetting the sequence.

Applications

• Microcontroller system configuration storage
• Calibration data retention
• Parameter logging

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the datasheet revision corresponds to the manufacturing date code. Ensure the design accounts for the device being marked as not recommended for new designs; consult updated product families if applicable.

Selection Notes

Select this component when an 8 Kbit capacity is required with SPI compatibility. Verify the operating voltage meets the minimum 2.5 V requirement. Consider the Industrial temperature range limits (-40°C to +85°C) against environmental conditions. Check if the legacy status impacts long-term supply availability.

Part Context

This part belongs to the 25AA080/25LC080/25C080 family of 8 Kbit Serial EEPROMs. It shares architectural similarities with other members but differs in voltage specifications and maximum clock frequencies. The 'I' suffix denotes the Industrial temperature range, while '/P' indicates the 8-lead PDIP package.

Replacement Considerations

Datasheet explicitly recommends using 25AA080A/B or 25LC080A/B series instead. Verify electrical compatibility regarding voltage ranges and timing parameters before substituting.
