Overview of JSMC08AUM3HYAEA-H5I - Industrial 8GB eMMC 5.1 153-FBGA (11.5x13mm)
The JSMC08AUM3HYAEA-H5I pairs 8GB of managed NAND with an industrial -40°C to 85°C rating, aimed at rugged designs that also need real capacity. It is built on a single 64Gb die behind an eMMC 5.1 controller, offering 7,818,182,656 bytes of user partition space (LBA 0x00E90000) in the 153-ball FBGA at 11.5 x 13.0 x 1.0mm. Where the commercial 8GB part stops at -25°C, this -H5I grade is qualified to the full -40°C cold limit, so it holds up in enclosures that see freezing starts.
Storage and interface
Sustained sequential performance is rated at 240MB/s read and 55MB/s write under HS400 with cache enabled, the same characterization as the commercial 8GB device, so the capacity and speed profile carry straight across while the temperature envelope widens. The eMMC 5.1 interface reaches up to 400MB/s at a 200MHz clock over an 8-bit bus with the 1.8V VCCQ option, and drops back cleanly to HS200 and legacy modes on hosts that need them. Power comes from a dual-rail arrangement: VCC at 2.7V to 3.6V for the NAND and VCCQ at 1.70V to 1.95V or 2.7V to 3.6V for the controller, with an on-chip LDO on the memory side.
Key Features
- Industrial temperature - guaranteed -40°C to 85°C operation, the reason to choose -H5I over the commercial grade.
- 8GB single-die density - one 64Gb die delivers about 7.8GB of user space without stacking.
- eMMC 5.1 feature set - Boot and RPMB partitions, command queuing, cache, Sanitize, Secure Erase and Trim, Field Firmware Update, and Device Health reporting.
- Enhanced area SLC mode - a user-defined region can operate in SLC mode for higher data integrity where it matters most.
Where It Fits
- Industrial gateways and controllers - capacity for logs and application data with a cold-rated storage device.
- Transportation and outdoor systems - fleet telematics, EV charging, and roadside units that face sub-zero mornings.
- Rugged data logging - the 55MB/s write rating supports steady capture in field equipment, with RPMB and secure write protection guarding critical records.
- Medical and instrumentation - portable diagnostic and test gear that must boot reliably across a wide temperature span.
Why Choose JSMC08AUM3HYAEA-H5I?
Choose the JSMC08AUM3HYAEA-H5I when a project needs both 8GB of managed storage and a genuine -40°C qualification in one part, rather than compromising on capacity to get the temperature grade. It shares footprint, interface, and rated throughput with the commercial 8GB version, so the cold rating is the deciding factor. Large Sector Size (4KB) is not supported, and storage without operation spans -40°C to 85°C.
