Overview
The Microchip Technology 25LC040AT-E/MNY is a 4 Kbit (512 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It operates on an SPI-compatible serial bus with a maximum clock frequency of 10 MHz. The device supports a supply voltage range of 2.5V to 5.5V and features a 16-byte page write capability. It is housed in an 8-lead TDFN package and is rated for an industrial temperature range of -40°C to +85°C.
Feature Summary
- Supports high-speed SPI communication with a maximum clock frequency of 10 MHz.
- Includes built-in hardware and software write protection mechanisms, including block protection and power-on data protection.
- Features a hold pin that allows the host to pause serial communication without resetting the sequence.
Applications
- Data storage in industrial control systems
- Configuration memory for microcontrollers
- Embedded sensor data logging
Procurement Notes
Verify the specific suffix 'MNY' corresponds to the 8-lead TDFN package and Industrial temperature grade (-40°C to +85°C). Confirm the 'E' designation indicates Automotive temperature qualification if required by the application environment. Ensure the datasheet DS21827H is referenced for accurate electrical characteristics and timing parameters.
Selection Notes
Select this component when a small footprint EEPROM is needed for SPI-based architectures. The 25LC040A series offers low power consumption and high reliability. Consider the TDFN package for surface-mount applications requiring compact board space. Verify voltage compatibility within the 2.5V to 5.5V range before integration.
Part Context
This part belongs to the 25LC040A family of 4 Kbit Serial EEPROMs from Microchip Technology. The family includes variants with different voltage ranges (1.8V-5.5V for 25AA040A vs 2.5V-5.5V for 25LC040A) and packages. The 'E' suffix denotes Automotive temperature range support, while 'I' denotes Industrial range.
Replacement Considerations
Direct replacements include other 25LC040A variants with compatible packages such as 25LC040AT-I/MNY or 25LC040AT-E/SN. Cross-family substitutes like 25AA040A require verification of the minimum supply voltage requirements.
