25LC010A-I/P

Overview

The Microchip Technology 25LC010A-I/P is a 1 Kbit (128 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It utilizes an SPI-compatible serial bus for communication, featuring a maximum clock frequency of 10 MHz. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports industrial temperature ranges from -40°C to +85°C. It is housed in an 8-lead PDIP package.

Feature Summary

• Supports write page mode allowing up to 16 bytes per cycle
• Includes built-in power-on/off data protection circuitry
• Features hardware write-protect pin for array security
• Provides block write protection with selectable segment levels

Applications

• Microcontroller configuration storage
• Calibration parameter retention
• Data logging applications
• Embedded system non-volatile memory

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) and '/P' indicates the PDIP package. Confirm RoHS compliance status as required by project specifications. Ensure the ordering code matches the exact 25LC010A variant to guarantee correct voltage and speed characteristics.

Selection Notes

Select this component when a 1 Kbit capacity is sufficient for application requirements. The SPI interface simplifies microcontroller integration compared to parallel memories. Consider the 10 MHz clock speed for high-throughput needs. Verify that the 2.5 V minimum operating voltage aligns with the system's power supply rails.

Part Context

This part belongs to the 25XX010A family of 1 Kbit SPI EEPROMs. The 'LC' designation specifies the 2.5 V to 5.5 V operating voltage range, distinguishing it from the 'AA' series which supports lower voltages down to 1.8 V. The 'I' suffix denotes the industrial temperature rating.

Replacement Considerations

The 25LC010AT-I/SN serves as a surface-mount alternative offering identical electrical performance in an SOIC package. For lower voltage applications requiring 1.8 V operation, the 25AA010A series provides functional compatibility.
