Overview
The Microchip Technology 25LC1024T-I/SM is a 1-Mbit (128K x 8) serial EEPROM utilizing an SPI-compatible interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 20 MHz at higher voltages or 10 MHz at lower voltages. The device features a 256-byte page size, a maximum write cycle time of 6 ms, and an industrial temperature range of -40°C to +85°C. Packaged in an 8-lead SOIJ format, it includes hardware write protection and deep power-down capabilities.
Feature Summary
- Supports byte and page-level write operations with self-timed erase cycles
- Includes sector write protection for specific memory segments
- Features built-in power-on/off data protection circuitry
- Provides hold functionality to pause serial communication without resetting sequences
Applications
- Microcontroller-based system configuration storage
- Calibration parameter persistence
- Data logging applications requiring non-volatile retention
Procurement Notes
Verify the suffix 'I' confirms the industrial temperature range (-40°C to +85°C). Confirm the 'SM' designation matches the required 8-lead SOIJ package type. Ensure the supply voltage requirements align with the 2.5V to 5.5V operational specifications provided in the datasheet.
Selection Notes
Select this component when a 1-Mbit capacity is required alongside standard SPI connectivity. Consider the 256-byte page size for write efficiency and verify that the industrial temperature rating meets environmental constraints. Evaluate the need for hardware write protection via the WP pin if security against accidental writes is critical.
Part Context
This part belongs to the 25LC1024 series of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with other members of the family but differs in package type and temperature grade. The 'T' indicates tape and reel packaging, while 'I' specifies the industrial temperature range.
Replacement Considerations
Consult official Microchip documentation for qualified replacements. Verify compatibility regarding voltage ranges, pin configurations, and command sets before substituting.
