Cheap alternatives to Mach 210s

Depending on the voltages you want to use (Mach210 is a 5V device). You could use the M4A5-32/32 which has a very similar spec and architecture (I once did the excercise). If you want to drive the cost further down and have 3.3V on the PCB you could use the LC4032V (superset of the M4A5). The device is 5V tolerant. You will need to work with your locl disti or direct Lattice sales channel for pricing.

Many thanks for your reply.

It's not essential I use the Lattice devices although it is an obvious migration. Some time ago there was talk of an equivalent Cypress part. It doesn't have to be a direct equivalent. I need 64 macrocells and around 36 I/Os. One device of twice the macrocells and I/Os is a possibility but these have historically cost more than 2 x the cost of a single smaller device. I just wanted a feel for what's around.

Many thanks again.

Xilinx XC9572XL is the best choice for cost and logic density. It is in system programmable. However it needs a 3.3V supply voltage, and has only 34 I/O's availlable in a 44pin package, so use a VQ64 package:

I understand that you like the architecture of the 9500. However in PLD terms this device family is mature. Nevertheless this family is widely used as is the Mach4K. If price is the major concern, I suggest to work with the distributor or the supplier.
