Microcontroller with 100+ I/O's?

Post by Gouron73 »

I have a project that needs a ton of I/O's and I don't want to deal with the nightmare of trying to synchronize several FPGA's to achieve the 100+ I/O's that I need.

Does anyone know of a reasonably priced FPGA that provides that many I/O pins?

If you have a processor with i2c, you can get hundreds of GPIO pins using these:

There's two options you can look for. Since your title says MCU and the OP says FPGA, I'll post both.

First there's the PIC32MZ from Microchip which is available in a 144-pin surface mount package: http://www.microchip.com/wwwproducts/en ... 1024EFE144
Word of warning: read the errata.

There's also the Spartan 6 from Xilinx, which is a FPGA that starts with 132 IO.

Both options likely have pre-built boards available if you look hard enough; I've seen a Sr. Design student last year use an evaluation board with a Spartan 6 on it to construct his final project.

Hope this helps.
