25LC010A-I/MS

Overview

The Microchip Technology 25LC010A-I/MS is a 1 Kbit (128 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It operates with a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 10 MHz. The device utilizes an SPI-compatible serial bus for communication, featuring a write page mode capable of handling up to 16 bytes per cycle. Internal write cycles complete within a maximum of 5 ms. It provides high reliability with 1,000,000 erase/write cycle endurance and data retention exceeding 200 years.

Feature Summary

• Supports sequential read operations and write page modes for efficient data transfer.
• Includes built-in hardware write protection via the WP pin and software block protection settings.
• Features power-on/off data protection circuitry and a write enable latch mechanism.
• Allows suspension of serial communication via the HOLD pin without resetting the sequence.

Applications

• Microcontroller system configuration storage
• Calibration parameter persistence
• Small data logging applications

Procurement Notes

Verify that the ordering suffix matches the required package type, as the base part number covers multiple physical formats. Confirm the temperature grade corresponds to the specific application environment requirements. Ensure the voltage specifications align with the target system's power rails before finalizing procurement orders.

Selection Notes

Select this component when a 1 Kbit capacity is sufficient for non-volatile data storage needs. Choose this model over the 25AA010A variant if the operating voltage must remain at or above 2.5V. Consider the MSOP package for surface-mount designs requiring compact footprints while maintaining industrial temperature ratings.

Part Context

This component belongs to the 25XX010A family of serial EEPROMs manufactured by Microchip Technology. The 'LC' designation indicates a low-voltage CMOS technology optimized for operation between 2.5V and 5.5V. The '-I' suffix specifies the Industrial temperature range, distinguishing it from Automotive or Extended variants within the same memory architecture.

Replacement Considerations

The 25AA010A-I/MS serves as a functional substitute with identical pinouts and instruction sets, differing primarily in its expanded 1.8V to 5.5V operating voltage range. Verify that the lower minimum voltage of the AA variant does not conflict with existing system power constraints.
