24CS128T-E/MWF66KVAO

Memory IC Overview

The Microchip Technology 24CS128T-E/MWF66KVAO is a 128 Kbit (16 K x 8) serial electrically erasable programmable read-only memory (EEPROM). It utilizes an I2C interface with support for high-speed mode operation up to 3.4 MHz. The device operates within a supply voltage range of 1.7 V to 5.5 V and is housed in an 8-pin VDFN package featuring wettable flanks. It is qualified for automotive applications, supporting an extended operating temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed I2C communication modes for efficient data transfer
• Automotive-grade qualification ensuring reliability under extreme thermal conditions
• Integrated error correction code (ECC) capabilities for enhanced data integrity

Memory IC Applications

• Automotive electronic control units requiring robust non-volatile storage
• Industrial systems demanding high-temperature operational stability
• Data acquisition modules needing reliable parameter retention

Memory IC Procurement Notes

Verify the specific suffix MWF66KVAO against official Microchip documentation to confirm the VDFN-8 wettable flank package and automotive grade designation. Ensure compatibility with I2C bus voltage levels and check for any recent product change notifications regarding manufacturing updates or lead times before finalizing procurement plans.

Memory IC Selection Notes

Select this component when automotive AEC-Q100 compliance and extended temperature ranges are mandatory. The inclusion of ECC makes it suitable for safety-critical applications where data corruption must be minimized. Compare pinout and package dimensions against existing PCB layouts to ensure the VDFN form factor fits the design constraints.

Memory IC Part Context

This part belongs to the 24CS series of serial EEPROMs designed specifically for automotive environments. Unlike standard industrial variants, the 'E' temperature grade and specific packaging options cater to the rigorous demands of vehicle electronics, providing long-term durability and resistance to harsh operating conditions.

Memory IC Replacement Considerations

Direct substitutes include other 24CS128 variants with identical electrical specifications but different packages, such as 24CS128T-E/SN66KVAO (SOIC-8) or 24CS128T-E/MS66KVAO (MSOP-8). Verify that the replacement maintains the same wettable flank requirement if drop-in board compatibility is critical.
