Overview
The Microchip Technology 25LC1024T-E/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, 1M erase/write cycle endurance, and data retention exceeding 200 years. It is housed in an 8-lead SOIJ package and qualified for the extended industrial temperature range of -40°C to +125°C.
Feature Summary
- Supports byte-level and page-level write operations with self-timed erase cycles.
Applications
- Microcontroller system data storage
- Configuration parameter retention
Procurement Notes
Verify that the ordering suffix 'E' corresponds to the extended industrial temperature range (-40°C to +125°C). Confirm the '/SM' designation matches the required 8-lead SOIJ surface-mount package. Ensure the specific revision level aligns with your design requirements.
Selection Notes
Select this component when high-density non-volatile storage is required alongside robust environmental tolerance. The extended temperature rating makes it suitable for demanding operational conditions where standard industrial grades may be insufficient.
Part Context
This part belongs to the 25LC1024 series of 1-Mbit SPI serial EEPROMs from Microchip Technology. The series offers various package options and temperature grades to accommodate different form factors and environmental constraints.
Replacement Considerations
Consult official documentation for verified substitutes such as the 25AA1024 or AT25M01.
FAQ
What is the maximum clock frequency supported by the 25LC1024?
The device supports a maximum clock frequency of 20 MHz when VCC is between 4.5V and 5.5V, and 10 MHz when VCC is between 2.5V and 5.5V.
How does the HOLD pin function during communication?
The HOLD pin allows the host to pause serial communication without resetting the sequence. Transitions on SI and SCK are ignored while the device is paused.
