We currently use an RCM3200 in our main product line. It's a great chip for what we're doing with it, except that it's soon going to be not fast enough at 40MHz.
Can anyone recommend a suitable, faster, alternative to it?
The key features that we need are:
At least 2, preferably 3 or more serial ports. At least 10 general purpose I/O pins, 26 or more would be the bee's knees. At least 1 pwm output, preferably 2 or more programmable pwm like the rabbit. Ethernet port with a UDP/IP stack.
500KB data store (flash, ram, it's not stored between sessions so I don't care) Enough program flash space for the UDP/IP stack and a simple tftp application.The programming environment is less important to me. It does, however, need to be usable for a 2-man development team (I'm software, my boss makes the hardware). Price per unit, anything under $200 is fine -- more than that and it would just take some evaluation to determine the advantage of the product to see if it's worth it.
The key that we're needing is SPEED.
Thank you for any suggestions you've got.
