any D1s/F133-A chips available ???

after researching datasheets and example board designs (thanx to all provided) and seeing all the people making boards I think I'm ready for a first pass prototyping board. Our focus is on RT-Thread or FreeRTOS lighting controllers with Ethernet to SDIO FPGA data handling. No LCD or video in/out. We've worked with SSD210 but are tired of no documentation of registers etc. even with a signed NDA.

I've looked all over for some sample quantities to prototype with. does anyone have on-hand or access to a modest supply? payment from USA but shipping to my agent in Guangzhou for assembly (or agent can pay in China).

Thanx,

Thanx all for input. Next Month is Monday, i'll order then  ;^)

@Blueskull
Not targeting SDIO, just an example. i can control the interface into my FPGA but can't on other chips. i may have need for other chips that will use SPI and by moving FPGA hi speed channel to SDIO it would free up SPI channels. Not reinventing the wheel, just porting years of knowledge/development on MCU platforms to this environment.

here's a 3D of a pre-production SSD212 design. considering jumping to F133-A ...

after years of fighting flash/ram sizes in MCU (PIC32, PSOC5, XMC4500, etc) the ability to program/buffer in a 64MB memory is unbelievable. we've had 10Base-T, then 100Base-T but very few MCU have 1000Base-T. one thing we fight in professional lighting displays is latency so the faster/wider the pipelines the better. we use an FPGA to take a buffer of lighting data and custom generate peripherals that are tailored to the pixel protocols. no need for fooling spi/uart to do the job with our custom drivers nailed to the protocol. not the only way to get there, just a path we are taking. we are near production on SSD212 products but they have been so difficult to work with on documentation. porting the drivers from linux to freertos when you don't know the register bits has been a pain in the ....

just our humble opinion after many years of product development.
