Datasheet

• High Priority Interrupt (HPI)
In some scenarios, different types of data on the device may have different priorities for the host. For
example, writing operation may be time consuming and therefore there might be a need to suppress
the writing to allow demand paging requests in order launch a process when requested by the user.
For more details, refer to section 6.6.26 of the JEDEC Standard Specification NO. JESD84-B451.
• H/W Reset
Hardware reset may be used by the host to reset the device, moving the device to a Pre-idle state
and disabling the power-on period write protect on blocks that was set as power-on write protect
before the reset was asserted. For more details, refer to section 6.15.9 of the JEDEC Standard
Specification NO.JESD84-B451.
• DDR I/F
Support DDR signaling to double bus performance. For more details, refer to JESD84-B451
standard.
• Replay Protected Memory Block
A signed access to a Replay Protected Memory Block is provided. This function provides means for
the system to store data to the specific memory area in an authenticated and replay protected
manner. For more details, refer to section 6.6.22 of the JEDEC standard Specification
NO.JESD84-B451.
• Background Operation
EMC210 has various maintenance operations need to perform internally. In order to reduce
latencies during time critical operation like read and write, it is better to execute maintenance
operation in other times – when the host is not being serviced. For more details, refer to section
6.6.25 of the JEDEC Standard Specification NO.JESD84-B451.
