I’m specifically interested in the SH7145 (SH-2 core)

Digikey part# HD64F7145F50V-ND

GNU toolchain support

Also, the M32/R core looks very interesting

So, how about it Olimex? :slight_smile:

Hi,

$16/100 pcs for 8bit micro @50Mhz? who will use these when there are ARMs at 1/3 of this price with better capabilities?

Best regards

Hi Tsvetan,

I see your point. The SUPER-H series is (from my understanding) a 32 bit processor solution. It looks like it may have better support with the GNU toolchain.

I have purchased quite a few different development platforms now (Olimex via Sparkfun) trying to find the ultimate solution. Microchip has wayyy to many problems with their hardware for my tastes (i.e. Errata and compiler issues). Not trying to start a war here, but I am done with them. Amazingly people must still buy them.

AVR ATMega128 has been very good to me so far, but I am looking for more powerful solution right now. The ARM core is definitely the main candidate on my list, but I’m not convinced that the debugging tools are completely polished yet. The OpenOCD project / ARM-USB-OCD combo seems to still need some work. It isn’t working too well for me anyway. I’m trying to find a good solution for development with Linux as the host platform and have the development tools “just work as expected”.

I think there would be others that would think along the same lines. I know I would be willing to pay the extra for system cost if the development tools are rock solid (mature) on Linux host platform… I am a newcomer to the 32 bit microcontroller arena, so I might be way off. Suggestions are welcome.

Thanks!

The Rowley CrossWorks ARM debugger is very good, and their tools are available for Linux.

That GNU C compiler looks very interesting! I have been patiently waiting the arrival of the Renesas R8C/23 (http://www.renesas.com/fmwk.jsp?cnt=r8c … c23_group/)

It seems to be quite similar to, say, an AVR, but with one very nice addition: CAN. It comes in a 9mmx9mm leaded package, while the CAN AVRs come in 16mmx16mm leaded packages and 9mmx9mm QFNs. Neither of those will work for my application as I need a chip that can fit on a 15mm wide board (3mm on each side of the QFN is not enough space to route traces around, and you can’t run traces on the top layer beneath the QFN as it has a ground pad).

So, do you know if that compiler will support the R8C/23? Also, how does one program one of these chips?

Looks like all of their cores are supported. Here is a list of tools

It appears RFLASH is the programming utility.

So, do you know if that compiler will support the R8C/23? Also, how does one program one of these chips?

Thanks. I will check that out. I looked at their compiler once, but I think I prefer GNU GCC environment. I had not thought of just using their debugger solution though… That might be a great combo.?
