Discussion Groups | Rabbit-Semi | Wich module is better
This is a group for folks designing and programming embedded systems using the Rabbit Semiconductor C-programmable microcontroller. Rabbit Semi is a spin-off from Z-World who makes a variety of embedded modules and tools. This group is not affiliated with either Rabbit or Z-World, but is a user forum for sharing ideas, asking questions, flaunting knowledge, and other typical user group stuff. The Rabbit is a powerful uC, supported by a full-featured C-compiler.
Wich module is better - Taris - Oct 30 15:02:31 2009
Hello
Could you help me with choosing a rabbit module. I need less 8 UDP and 8 TCP/IP connection at the same time for communication with other devices, web server for configuration and set up some parameters of module, possibility reliable firmware updates through ethernet. Is it possible to make this application with one of rabbit modules? Please advice.
Best regards

Almost any of them can do this many connections. If you want to be able
to support more, use a module with more than 128K of RAM.
I like the RCM3000/32xx/33xx/3900 as they are pin-compatible and have
lots of I/O.
The RCM3700 is one of the cheaper ones to use. I use them but they don't
have good mechanical mounting (add holes in the main board for zip ties.0
I don't care for the 4k modules as they have limited I/O (and with DC's
compiler, they are no faster than 3k modules.) The 5k module slook good,
but most only have 128k RAM.

Hello,
Before writing this program, I am afraid that I will miss the root program and data memory. At first glance, some of rabbit cores have a lot of data and program memory (512KB SRAM and 512KB Flash), but with large numbers of TCP / IP, UDP channels and RabbitWeb and DLM/DLP (download manager for upgrade firmware) the program requires a lot of both ROOT program and data storage (not XMEM which are a lot of and usually enough). It's my opinion. I am also afraid a lack of speed through TCP/IP channels. My program must parse a request and answer less than 10ms. The TCP and UDP listener shall be capable of at least 8 simultaneous connections. I think that RCM3xxx it is not powerful enough for this purpose. It's my opinion.
I would like hear your point of view.
Best regards
