Gerade auf der VLSI Website entdeckt.
VS23S010C-L
Ein SPI/Parallel RAM Chip mit eingebautem PAL/NTSC Video Controller.
Samples und komplettes Datenblatt scheint es schon zu geben.
Sowas wollte ich schon immer haben :)
Die Grafikeinheit ist frei programmierbar was Auflösung und
Farbtiefe betrifft. Natürlich durch die 128K RAM begrenzt.
