25LC010A-E/MS

Overview

The Microchip Technology 25LC010A-E/MS is a 1 Kbit (128 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 10 MHz via an SPI-compatible serial bus. The device features a write page mode allowing up to 16 bytes per cycle, with self-timed erase and write cycles completing in a maximum of 5 ms. It is housed in an 8-lead MSOP package and is rated for an industrial temperature range of -40°C to +125°C.

Feature Summary

• Supports high-speed serial communication through a standard SPI interface with a maximum clock frequency of 10 MHz.
• Includes hardware write protection mechanisms such as a dedicated WP pin, power-on/off data protection circuitry, and a write enable latch.
• Offers flexible block write protection capabilities, allowing users to protect none, one-quarter, one-half, or the entire memory array.
• Features a HOLD input pin that allows the host to pause serial transmission without resetting the sequence, facilitating higher priority interrupt servicing.

Applications

• Configuration storage in microcontroller-based systems
• Calibration parameter persistence
• Data logging applications requiring non-volatile retention

Procurement Notes

Verify the specific suffix 'E' indicates the automotive temperature grade (-40°C to +125°C) and 'MS' denotes the 8-lead MSOP package. Confirm the minimum operating voltage requirement of 2.5V aligns with your system's power rails, as this differs from the 1.8V minimum of the 25AA010A variant. Ensure the design accounts for the 5 mA maximum write current during active programming cycles.

Selection Notes

Select this component when an SPI EEPROM requires operation at temperatures up to 125°C. The 25LC010A-E/MS is suitable for designs needing a 2.5V minimum supply voltage, distinguishing it from lower-voltage alternatives like the 25AA010A series. Consider the 16-byte page size for write efficiency and utilize the built-in block protection features for critical data segments.

Part Context

This part belongs to the 25XX010A family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares identical functional specifications and instruction sets, differing primarily in operating voltage ranges and temperature grades. The 'LC' designation specifically identifies the 2.5V to 5.5V voltage range variant.

Replacement Considerations

The 25LC010A-I/MS serves as a direct replacement if the application does not require the extended upper temperature limit of 125°C. Other compatible packages within the same electrical specification include the 25LC010A-P (PDIP), 25LC010A-SN (SOIC), and 25LC010A-ST (TSSOP).
