MTFC4GACAJCN-4M IT

The device is rated for an industrial temperature range of -40°C to +85°C. The "IT" suffix in the part number designates Industrial Temperature grade, indicating it is qualified for applications operating in extreme thermal environments across this full range

The MTFC4GACAJCN-4M IT complies with the eMMC 5.0 specification and features a maximum clock frequency of 52 MHz. The memory interface operates in parallel mode and includes an integrated MMC controller with NAND Flash management.

While both are 32 Gbit eMMC Flash memory devices in the same 153-ball VFBGA package, the "-1M WT" suffix supports the higher-performance eMMC 5.1 interface (up to HS400 mode with 400 MB/s sequential read), whereas the "-4M IT" suffix is limited to eMMC 5.0 (max 160 MB/s sequential read). Both share the same industrial-grade temperature range (-40°C to +85°C).

This device has been officially designated as Obsolete / No Longer Manufactured (End-of-Life) by Micron Technology. Most major authorized distributors including DigiKey and Newark list it as discontinued status for new designs
