Hi,
why not using another PIC??
There are many out there with 2 USART, 2 SPI.....(example PIC24FJ128GA010)

Best regards

You can use the PIC18F6620-6720 family PIC processor, there are two serial available. I've used this micro to build a custom PLC with 14 optoisolated I/O, two serial port (one for a modem and one used to communicate with a embedded PC), 3 analog input, two 4-20mA current loop input, 14 NPN outputs, 4 relay output and 2 output with two interleaved relay (used to drive a DC motor). I've built this just to do some experiment with this micro and also to have a developing board with several I/O, also I've do some experiment with the 4-20mA current loop. Now I'm planning to build a home made PLC with a structure like the real commercial PLC (SIEMENS, OMRON), then make a card with the CPU, a card with the power-supply, a card with I/O and make all together by using a dedicated bus to have some modularity.
