MStar Datasheets

Scart to HDMI
A common example of the SCART to HDMI adaptors found on Aliexpress, eBay, etc

I've previously blogged about Chinese SCART adaptors. These are very low cost adaptors which convert RGB SCART to HDMI, with two main variations based on their board labels: SCART+HD2 HDMI 2014/12/23 and SHD1000 V1.

In the comments, readers identified that the main IC driving these is the MST6M182 (specifically mst6m182xst-z1). After much searching online and a hint from reader mmuman I managed to track down the datasheet or at least one close enough.

Of note to retro-gaming and retro-computing enthusiasts will be the registers for de-interlacing, including options to disable it entirely (USR_INTLAC). I'm keen to hook-up a micro and start fiddling with registers, as I suspect these could be a very good low-cost option if adequate control of the images was possible

In addition, I've created a source repository to collect these datasheets. It's available at If you have any further datasheets, please submit a pull request, as I'd be happy to put them up on that repo.
