Processor and memory subsystem

The heart of AIDA module is composed by the following components:

• i.MX95x or i.MX937x SoC application processor
• Power supply unit
• LPDDR5 memory bank
• eMMC and NOR SPI flash storage
• Connectors:
  • 1 x 260 pins SO-DIMM edge connector with interfaces signals partially compatible with ORCA SOM

This chapter shortly describes the main AIDA components.

RAM memory bank

LPDD5 SDRAM memory bank is composed by 1x 32-bit width chip. The following table reports the SDRAM specifications:

CPU connection	Multi-mode DDR controller (MMDC)
Size max	16 GB
Width	32 bit

eMMC flash bank

On board main storage memory eMMC is connected to the SDIO1 interface and it can act as boot peripheral. The following table reports the eMMC flash specifications:

CPU connection	SD1
Size min	8 GB
Size max	64 GB
Bootable	Yes

NOR flash bank

Alternative option for main storage memory can be a serial NOR flash connected to the CPU's Quad serial flash controller. It can act as boot peripheral. The following table reports the NOR flash specifications:

CPU connection	SPI Serial NOR flash controller
Size min	16MB
Size max	32MB
Width	4 bit SPI mode
Bootable	Yes

Power supply unit

AIDA embeds all the elements required for powering the unit, therefore power sequencing is self-contained and simplified. Nevertheless, power must be provided from carrier board, and therefore users should be aware of the ranges power supply can assume as well as all other parameters.
