Hitachi has announced
the availability of a new H8S
series microcontroller, the H8S/2674R. The new H8S is a 33 MHz, 16
bit microcontroller with a built-in SDRAM interface, DMA, DTC, 6
channel 16 bit timer, watchdog timer, programmable pulse generator, 12
channel 10 bit A-to-D convertor, 4-channel 8-bit DAC, 3 serial ports,
and up to 115 I/O lines. Evaluation boards are $199 and include Ethernet
and serial ports, 4MB flash, and 8 MB SDRAM. And, suprise, there's
already an H8S uClinux
Hitachi appears to be burdened with old style dealer/vendor networks.
Thus you have to deal with a local vendor or distributor to get
anything. So if the vendor doesn't see a lot of money in it, they won't
deal with you. Unless it is obsololete or surplus you usually can't get
the parts off the internet or through any of the regular internet
vendors. Of course maybe there is one I missed. Arrow, Pioneer, Digikey
doesn't sell them.
Also the Hitachi HEW IDE development environment has a 30 day timelimit
on usage, and costs at least $1,200 US to get. There looks to be a GCC
version compiler but I haven't tried it yet. No one else seems to have
alternate compiler IDE programmer sources for the H8... chips. Which
isn't a good sign. Hitachi might be overly repressive on allowing third
party languages and IDE's to be developed.
Although, I like the Hitachi chips, it doesn't look to be hobbyist
friendly, or even whether they want small businesses to use their
products. They seem to cater to large corporate accounts.
It looks like the PICs, Atmels, Cypress, Cygnal, Ubicom, Dallas Maxim,
TI MSP430's, Motorola H08Q series have effectively out manuevered
Hitachi in the MCU markets.
It would help more if their web site was easier to navigate through.
Other than that, they are pretty neat chips. I wanted to use the 16bit
H8's for quite a while now. Really nice for easy 16bit ADC readings.
Well basically i am an student and i am intrested in knowing about
microcontrollers ,well i found ur microcontroller very intresting and i
just want to have more information on the same along with the various
price for ur microcontroller.
well mail back to me at ,
well waiting for ur earnest reply,
Sometimes someone on Ebay puts up some H8's for sale.
There is a company in Europe with some development boards for sale now.
IAR has a compiler but it appears to be expensive. It may be the same
one Hitachi is promoting too.
There is the GCC cross compiler which looks pretty good.
Hitachi has a "board in the bag" H8tiny promotion going, but you have
to get it through your local distributor.
Hitachi has finally gotten their H8tiny 64k limited edition IDE
compiler available. It's somewhere on their website, you'll have to
hunt for it. Earlier they had it available but the way it was worded
made it seem like it was going to expire in 30 days anyway. But it was
almost impossible to find unless a distributor gave you the URL to it.
They also have a Flash Programming Utility that is separate that works
well for programming the MCU's.
Now if they would have a forum site like www.avrfreaks.net has the
chips might take off pretty well.
Except for what shows up surplus, they still have no easy source for
buying the chips except through a distributor.
