25LC010A-E/P

Overview

The Microchip Technology 25LC010A-E/P is a 1 Kbit (128 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It utilizes a standard SPI-compatible serial bus for communication, requiring SCK, SI, SO, and CS signals. The device operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 10 MHz at voltages between 4.5V and 5.5V. It features self-timed erase and write cycles with a maximum duration of 5 ms. The component is housed in an 8-lead PDIP package and is rated for an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Supports up to 16-byte page write operations for efficient data programming.
• Includes hardware write protection via the WP pin and software block protection settings.
• Features power-on/off data protection circuitry to prevent inadvertent writes.
• Allows serial communication pausing via the HOLD input without resetting the sequence.

Applications

• Microcontroller configuration storage
• Calibration parameter retention
• Device identification data logging

Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'E' suffix indicates an extended temperature range (-40°C to +125°C), while 'I' denotes industrial range. The '/P' suffix specifies the 8-lead PDIP package. Confirm RoHS compliance status and ensure the voltage requirements align with the system design before procurement.

Selection Notes

Select this component when a 1 Kbit non-volatile memory solution is required with SPI interface compatibility. Ensure the application environment stays within the specified -40°C to +125°C operating range. Verify that the system voltage remains between 2.5V and 5.5V to maintain proper functionality and adhere to the absolute maximum ratings defined in the datasheet.

Part Context

This part belongs to the 25XX010A family of 1 Kbit SPI EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 25AA010A but differs in minimum operating voltage and temperature rating. The family offers various package options including SOIC, TSSOP, and DFN, providing flexibility for different PCB layout constraints and assembly methods.

Replacement Considerations

The 25LC010A-I/P is a compatible alternative offering the same electrical characteristics but with a restricted industrial temperature range of -40°C to +85°C. Other members of the 25LC010A series may be considered if different packaging formats are required, provided the temperature and voltage specifications remain suitable for the target application.
