Re: Terriblefire Accelerators

TF53x with SDRAM will be a pain in the @ss,
unless You'll go beyond 100x100mm... :roll:
There isn't much free space for level shifters..
Maybe it is possible to use one big cpld instead of two smaller? :geek:

Re: Terriblefire Accelerators

Sure, hope to help with some betatests as soon as i get my hands on pcb's :P

As about offered price - of course it will be higher than TF328 because of CPU socket, CPU itself, cpld price and other additional components, yet it will be very attractive compared to SX32..

Re: Terriblefire Accelerators

Oh i see..
These RAMs are (almost) same TSOPII 54pins, with the difference that Alliance are cheaper.
will test Alliance and Winbond RAM - already have these chips here, also Xilinx CPLD's!

Re: Terriblefire Accelerators

Exactly!
That is what i wanted to know!
I strongly recommend You to choose these SDRAM chips: AS4C16M16SA-6TIN
These are cheap, running @166Mhz, this will allow to go 64MB - that is enough for anything..
