Hi, 

I need an FPGA to store a lookup table a to control a DAC. Suppose I know the size of the lookup table (X data entries of Y bits each), how can I know what is the smallest FPGA I can use for that purpose? 

 

Thanks in advance

A lookup table would be preferably stored in an internal ROM and not need much logic resources beside it. Internal RAM/ROM sizes can be found in the overview chapter of a device hardware manual. A small device (EP3C5) has e.g. 23 k words of 18 bit wide memory
