Key Features
- The JEDEC e∙MMCTM compliant interface handles essential functions, including writing block management, error correction and driver software. It simplifies system development, allowing manufacturers to minimize development costs and speed up time to market for new and upgraded products. Additionally, new features[5] among them BKOPS control, Cache Barrier, Cache Flushing Report, and Large RPMB Write, are applied to the new products to enhance usability.
- The 8GB to 64GB products are sealed in a small FBGA package measuring just 11mm x 10mm and are suitable for smartphones, tablet PCs and wearable devices where miniaturization and weight savings are requirements.
- Embedded in a system, the 128GB products can record up to 16.3 hours of full spec high definition video and 39.7 hours of standard definition video[6].

“BKOPS control” is a function where the host allows the device to perform background operation during the device’s idle time. “Cache Barrier” is a function that controls when cache data is written to the memory chip. “Cache Flushing Report” is a function that informs the host if the device’s flushing policy is FIFO or not. “Large RPMB write” is a function that enhances the data size that can be written to the RPMB area to 8kB. |
