Allwinner V3LP gets low voltage RAM, should replace Allwinner V3S dual camera SoC

Allwinner V3LP is a single-core Cortex-A7 processor for dual-camera systems with the exact same specifications as the Allwinner V3S processor introduced in 2016, except it should be more power efficient with a lower DDR operating voltage of 1.5V instead of 1.8V.

Sochip explains that procuring the integrated DDR2 in the Allwinner V3s design is challenging, so Allwinner has replaced the memory in the pin-to-pin compatible Allwinner V3LP with more broadly available and lower power RAM.

Allwinner V3LP

Allwinner V3LP specifications:

  • CPU – ARM Cortex-A7 @ up to 1.2 GHz
  • Memory – Integrated 64MB DDR2 DRAM @ 1.5 V
  • Storage I/F – SD 2.0, eMMC 4.41, SPI NAND flash, SPI NOR flash
  • Audio Codec – 92dB audio codec supporting 2x ADC channels and 2x DAC channels, 1x low-noise analog microphone bias output, 1x microphone input and 1x stereo microphone output
  • Video Processing Unit
    • Encoding – 1080p@40fps or 1080p@30fps + VGA@30fps H.264
    • Decoding – 1080@30fps H.264 and MJPEG
  • Video Input/Output
    • 8/10/12-bit parallel CSI and 4-lane MIPI CSI2
    • Up to 5M CMOS sensor
    • RGB/i80/LVDS LCD up to 1024×768 resolution
  • Peripherals
    • 3x SD card controllers
    • USB 2.0 OTG
    • EMAC+PHY
  • ISP
    • Integrated “Hawkview” ISP up to 5M pixels
    • Supports 2x channel outputs for display and encoding respectively
    • Supports various input and output formats
    • Supports AE/AF/AWB
    • Supports saturation adjustment/ noise reduction/ defect pixel correction/distortion correction
  • Package – 128-pin eLQFP

The software will mostly be compatible, except for the RAM, and Sochip tells us to contact them for further details and the software patch, which I was not able to find publicly at the time of writing. They also mentioned that the Allwinner V3S may become EOL in the near future.

There’s very little information about the new Allwinner V3LP on the Internet, but Sochip sells the chip for the same price ($3.85 in low quantities) on Alibaba as the Allwinner V3S.

Thanks to Stuart for the tip.

It would be better if Allwinner updated a DDR3 version of V3s

Allwinner/SoChip already has the S3 which is the same sun8iw8p1 CPU die with a 128MB SIP 16-bit DDR3 die in an FBGA234 package:

Such changes make the use cost of S3 more than that of V3s. I hope that there can be an upgrade of DDR3 and the others remain unchanged.S3 brings out more pins, which is very good, but after all, the parameters of V3s are enough for some simple display applications.

Adding an internal microcontroller for embedded projects would be quite useful.

That would require redoing the chip. They’ve just changed the DDR2 die that is bonded to the SoC die in the package.

Anyhoo.. I thought all of the 32bit sunxi chips had an OpenRISC core.

AFAIK V3/V3s/S3 were missing the CPUS/ARISC core already.

Thanks. I checked wikipedia 🙂 No LPDDR or DDR2 at 1.5V.
This has to be DDR3 (or DDR3L) the only 1.5V RAM ever?

Search for DDR2L and you’ll find it.
