2.4. eMMC Storage
The PICO-IMX6UL-EMMC can be ordered with onboard eMMC storage in different configurations and
capacity.
The onboard eMMC device is connected on the SD1 pins of the i.MX6Ultralite processor in an 8 bit
width configuration.
The following eMMC chips have been validated and tested on the PICO-IMX6UL-EMMC Compute
Module:
2.4.1. Sandisk iNAND
iNAND Ultra is an Embedded Flash Drive (EFD) designed for mobile handsets and consumer
electronic devices. iNAND Ultra is a hybrid device combining an embedded thin flash controller and
standard MLC NAND flash memory, with an industry standard e.MMC 4.511 interface. Empowered
with a new e.MMC4.51 feature set such as Power Off Notifications and Packed commands, as well as
legacy e.MMC4.41 features such as Boot and RPMB partitions, HPI, and HW Reset the iNAND Ultra
e.MMC is the optimal device for reliable code and data storage.
iNAND provides mass storage of up to 128GB in JEDEC compatible form factors, with low power
consumption and high performance.
In addition to the high reliability and high system performance, it offers plug-and-play integration and
support for multiple NAND technology transitions, as well as features such as advanced power
management scheme.
iNAND Ultra uses advanced Multi-Level Cell (MLC) NAND flash technology, enhanced by embedded
flash management software running as firmware on the flash controller.
The architecture and embedded firmware fully emulates a hard disk to the host processor, enabling
read/write operations identical to a standard, sector-based hard drive. In addition, SanDisk firmware
employs patented methods, such as virtual mapping, dynamic and static wear-levelling, and automatic
block management to ensure high data reliability and maximize flash life expectancy.
