I am looking for some programable logic, something pretty small - i guess no more than 20 flip flops and just a few i/o, running at <1MHz. The key is that it needs to be very low power, so no more than 1mA when running, preferably <0.5mA.
I found ATF16LV8C from atmel, but now that I read the datasheet again it seems to be very power hungry, so do you guys have any recommendations for something that might actually work for me?
I have, I am using MSP430 as a main controller, but what I wanted was a hardware decoder for the modified muller encoding used in rfid cards, but the 8mhz was not enough for the decoding scheme I wanted to do, leaving just 12 clocks between samples. Now that I have a better understanding of the encoding I think I should be able to do the logic using just the micro.
But anyway this detour sure showed me how big is the gap between discrete logic chips and programmable logic.
Because the thing is powered from the RF field of the card reader, and the max. current I can get is 3mA without any headroom for modulation. Thankfully the MSP430 takes only 350uA per MHz.
