The uCsimm module is a microcontroller module built specifically for the uClinux Operating System. It stands an inch high, with a standard 30-pin SIMM form factor. The uCsimm is a perfect microcontroller for embedded systems that require stability, single process functionality, and ethernet capability, in a compact and modular form factor. There are innumerable uses for the uCsimm , but in the past, it has been used as everything from a webserver to a Programmable Logic Controller.
Good things come in small packages.
There is also a built-in LCD panel driver capable of displaying QVGA at a resolution of 320 x 240. We have also taken a few pictures of the first completed prototypes. 3 wire serial a 3.3 Volt draw. When idle, it draws only microamps. A copy of an early oscilloscope tracing can be found on the uCsimm Real-time port page .
