SAMA5D2 Based SiPs Combine ARM Cortex-A5 Processor With Up to 128MB DDR2

Orange Pi Development Boards

Atmel SAMA5D2 ARM Cortex-A5 processor was released about two years ago with extended temperature range and lower power consumption compared to previous SAMAD5 processors, with the new SoC still targeting industrial Internet of Things (IIoT), wearables and point of sale applications.

In recent years, we’ve seen companies packing main components into systems-in-package (SiP) with products such as Octavo Systems OSD3358 and Espressif Systems ESP32-PICO-D4 with integrate an existing processor with memory, storage, and/or PMIC. Microchip (previously Atmel) has now done the same for their SAMA5D2 processors with SiPs combining the Cortex A5 SoC with DDR2 memory.

    Wha’s the target market for this? They’re pretty expensive chips. What about the Allwinner V3?

    Chips made by western vendors are always more expensive. Aside from that the V3 is probably ok if you only want GPIOs but standard embedded stuff like multiple ADC channels is missing.

    Target market of this is going to be applications where a beefy MCU will probably do but you also want a proper MMU and maybe run a linux + busybox style setup. I think they should have probably come out with a lower pin count BGA or TQFP too though.

    Probably many of the same sockets that the Octavo Systems BeagleBone-in-Package is targeting: high-security high-performance low-cost Things at the volume end, makers at the singles end. When you account for the DDR2 by subtracting $5, and also consider the cost savings from integrated DDR and being able to use lower-spec pc boards due to the 0.8mm ball pitch, this is not such a bad deal. It appears they’re for sale now at DigiKey for $13.05 each.

    Can these things compress video to H.264 coming from the camera ISC interface? I know the SAMA5D4 offer hardware compression but I’m unclear whether the D2 is capable of running the necessary software. Both software availability and hardware capability/speed.
