BPI Tech, a spinoff from SinoVoIP, has introduced a new single board computer with Banana Pi BPI-F2S powered by SunPlus SP7021 “Plus1” SoC with four Cortex-A7 cores, one older ARM9 real-time core, and one even older 8051 IO controller. The chip also embeds up to 512MB DDR3 memory.
The board comes an 8GB flash, dual Fast Ethernet, HDMI, a 40-pin Raspberry Pi compatible GPIO header, as well as headers for an optional Xilinx Artix-7 FPGA expansion board.

Sunplus SP7021-IS comes with 128MB DDR3, while SP7021-IF gets 512MB DDR3. All I/Os and peripherals are said to be accessible by Cortex-A7, ARM926, and 8051 cores.
More details about the processor can be found on the processor’s Wiki. Documentation looks good enough to get started, but access to the source code requires username and password.
Sunplus SP7021-IF with 512MB RAM is sold for $20 on Tibbo website.

Hmm yet another banana pi with totally new soc.
now ,we use it as ic design education and FPGA development educationo at the university
Don’t care much for the board but that sunplus chip looks interesting. It’s a shame it’s a bit pricey.
The chip is industrial grade and supports the -40-85 temperature range
Is it? 20$ for 4xCortexA7 with integrated 512MB DDR, with additional ARM926 core and 8051 microcontroller and all of that in easy to use QFP176. Is it really expensive? No need for pmic – just 3.3V Easy PCB design thanks to integrated RAM and pin multiplexer. For me it’s not that expensive.
I bought few of them and I’m designing my own PCB for it. But the big problem is lack of detailed documentation. I contacted SunPlus and they say that they are finishing technical manual and soon will be available.
>Is it? 20$ for 4xCortexA7 with integrated 512MB DDR, Single core A7 with memory is in the few dollars range now. A complete solder down module for a RK3308 with memory and storage is ~$10. The octavo SiP with the TI SoCs in them are this sort of price range. >with additional ARM926 core and 8051 microcontroller The extra ARM core is nice. You usually get something like an 8051 or a cortex m on SoCs like this for power management though. >and all of that in easy to use QFP176. It’s better than BGA for 2 layer boards but… Read more »
Octavo is nice but their price is so out of 20$ range., example: https://pl.mouser.com/ProductDetail/Octavo-Systems/OSD32MP157C-512M-BAA-ES?qs=%2Fha2pyFaduiA2shJvuMjqMkkPsiuOj9Vapno5MT1ZAt2TxSUGSgE7Q==
2 cores, slower BGA, etc.
Or maybe I can’t find what you mean.
> On the other hand the chips I’ve been messing with that have integrated memory are really small (QFN80) and > very cheap.
I’d be more than happy if you shared some more info like symbol, manufacturer, links, anything.
>Octavo is nice but their price is so out of 20$ range., example:
>Or maybe I can’t find what you mean.
Octavo say they are $26 at 1k units. Of course the specs aren’t the same but if you want a solid platform they would make sense. If you really need 4 cores the RK3308 modules might make more sense and so on. $20 seems expensive for an unknown brand with older A7 cores.
>I’d be more than happy if you shared some more info like symbol, manufacturer, links, anything.

It’s true that this chip is something new but it doesn’t sound reasonable to rule it out just because of that. SUNPLUS is that unknown. It costs 20$ at 1 piece. I still think it’s not that expensive. Chips you linked are not general purpose devices. They are dedicated and probably not easy to buy. They are fine for what they were designed but not for general purpose as SP7021 is for. I was looking for some alternative few weeks ago and couldn’t find anything so if the chip works fine then the price is really fine too. But I’m… Read more »
>It costs 20$ at 1 piece. I still think it’s not that expensive. $20 means it’s no good really for quick projects that might not work out. Of course if it works for your situation more power to you. >Chips you linked are not general purpose devices. They work just fine for a lot of things. Being IP camera chips is why they have DDR built in and are in QFN (so it’s easier to get the sensor on the other side of the board). I have one driving a t-slot bar/3d printed rover around at the moment.. >They are… Read more »
> If you want one or two find my email address on github and I’ll send you some. Thanks for that. Some of the chips are really, really nice. I also prefer QFN packages because I find them easier to solder than QFP even with hotair. But I have an reflow oven, thanks to which QFN is nothing special. And QFN are significantly smaller than QFP which is quite important in almost every of my projects. But SP7021 specs fits perfectly to one of current projects for my client so I will give it a try first. Today I received… Read more »
Do you mind sharing some of the reverse engineering results you have gotten?
Checked the spec, but it seems no ADC ?
Anyone have the idea of where to buy this official demo board or evaluation kit? The Banana BPi-F2S board still not yet open for sell
There’s often a six months lag between Banana Pi announcements and actual availability.
BPI-F2S board is now available on
