Vampire 600: Vampire 600 V2
Posted on Thursday, March 19 2015 @ 16:43:01 CDT by majsta

Since demand for Vampire 600 V1 was so high I decided to redesign the board, add some more features, bigger FPGA, make board smaller and in any way better designed. Real reason for doing this was high demand for V1 I was unable to fulfill. All day night I was soldering to produce enough boards and I just couldn't keep up with that. Also my problems with customs I have mentioned number of times on various forums. Another reason was bug we had in V1 regarding RESET, bug was solved later in code but I didn't liked the idea to continue development of that card who has hardware bug. In V1 we had small FPGA, at the time that was more than enough but after apollo-team started to port Phoenix core to Vampire design soon enough we end up with lack of LE in our FPGA. For emulating MC68000 8K LE FPGA was enough but after we decided to emulate MC68020 instructions each day this FPGA was telling us that we are wasting our time. This time we will try to not create the same mistake. For easier soldering we are going with FPGA build in BGA package. This FPGA also have some benefits because his PLL can directly accept 7MHz signal from Amiga motherboard so we don't need to use external crystal oscillator on the board to get system synchronization to the mentioned clock signal. Memory size and model will stay the same, so for FastRam we will have 64MB of SDRAM memory who is better designed now regarding traces length. PCB itself is done in 4-layers and that will secure better GND plane and such thing is important if we aim for higher frequencies. For voltage regulation this time switching regulators are used instead linear ones and that will ensure proper work with any Amiga power supply because it will give enough power no matter how core inside of FPGA become complex and how much current it will take. On the board more capacitors are added, and there also we pickup smaller sizes 0402. All of that ensured that this board with his size of 50mmX100mm have good chances to become fastest and smallest Amiga accelerator board ever produced. Designing such board was nightmare because FPGA pads pitch was 0.8mm so Via hole diameter between those pads needed to be 0.2mm and that is something hard to produce for most of the PCB manufacturers. I played a risky game here now knowing how much production of such board can cost and placed the price of the board to 90 Eur before quotation from PCB manufacturer is finished. But after so much work it is about the time to have some luck. Board can be pre-ordered on Amibay or directly contacting me. To understand complexity of this design please look at the pictures found in (Read More, Pictures, Files...) of this article.

URGENT UPDATE: March 29, 2015
Quick update to explain new situation. As the Phoenix core getting bigger and more complex (having 3 instructions per clk as we speak) with future possibility to add FPU and get into never seen performance at least in Amiga world I had to change few things regarding design. This will affect the price since I just can't find a way to produce card for 90Eur and satisfy Phoenix core needs in the same time. Inside apollo-team we had 3 day long discussion about this. 10K LE Altera Cyclone III could easily fit in that price range but simply that is not enough for Phoenix. So new redesign is taking place and we will use 40K LE Cyclone III FPGA device instead and that is something I can't get cheap. What is discovered that price needs to go up to 120Eur now to cover everything. Also I have decided to cover all loses for early pre-ordered cards so this will not have any affect to those who already ordered and paid for their cards. So from now I can only accept 120EUR for pre-orders. Shipping for Europe 5EUR, rest of the world 10EUR.
