microcontroller

Hi friends,
can any one please suggest me a micro controller which will have the following features.
1.minimum five 12bit ADC(To convert voltage range 0-5V)
2.minimum three 12bit DAC(outut should be 0-5V range only)
3.UART connectivity.
4.minimum 16 bit micro controller.
5.minimum 32 I/O lines

i have searched so much time for this type of micro controller but failed to find it.
can any one please tell me is there any micro controller which will have above features or near to that features,thanks in advance.
 

Re: microcontroller

only arm controller may fit.
but for extra adc and dacs you have to connect external ones only.
search for philips 'lpc ' series arm controllers .

Hi,
You can take a look at the PIC24, dsPIC33, ATxmega, PIC32, AVR32. All of these are quite impressive chips.

Hope this helps.

Hi,
thanks for your suggestions,i have a doubt some of microcontrollers suggested by you people are operated in the range of 0-3.6V, but as i told you my ADC and DAC should be operate on 0-5V,if the microcontrollers are operate on 3.6V may i give 5V to ADC pin if not , please suggest me microcontroller which will operate on 5V and it should be having above features.
 

as far as i know most arm controllers use standard supply is 5volts .

low voltage versions are special types.

can you please specify one micro controller with 5V , it is very urgent requirement for me
 

please check str731 or 735 series.
may suit you.

Hi,
What about dsPIC30F5015? It has an operating range of 2.5v to 5.5v. 30MIPS maximum. 16-bit. 16-ch 10-bit ADC. UART, SPI, I2C.

Hope this helps.
Tahmid.
 

lot of help are avialable in this post in choosing the rquired controller.

choose any one , PIC , atmega or arm whichever is suitable to you.

PIC is always less costlier in some version , if cost is the factor for you.

Logic high of most 16bit/32bit controllers are less than 5v (<=3.6v).

Totally. Always use what you think would suit you best, cause all of them are very good chips.

I guess this depends a lot on where you live or work and the popularity of the microcontrollers at that location. Over here a PIC12F675 is the same price as an ATmega8, ATmega88 slightly more expensive and an 18F2550/4550 about 4 to 5 times as expensive. So you see what I mean.

I don't know about ARM, but dsPIC33, PIC24, PIC32, AVR32, ATxmega all operate at <= 3.6v. Of course, there is an exception: the dsPIC30.

Hope this helps.

Ya, PIC16 series controllers are very cheaper here (less expensive than AVR) but PIC18 series controllers are a little bit expensive than AVR. But I am always using
my microchipdirect account to buy PIC controllers etc (Mass purchasing [cost of PIC<cost of AVR])...and AVR controllers from local stores.

Tahmid.

working voltage of most high end processors and mid range controllers are always less than 3.6v, increase in integration density cause reduction in supply voltage but IO pins of these controllers are 5v tolerant.

Try any op-amp with suitable gain.


Good luck.
 

Well,
one ARM Cortex-M3 based devices that comes somewhat close to your requirements is the Toshiba TMPM380
**broken link removed**
There are (very few) new 5V types and this device is one of them.

Well Is it possible to resolve the ADC issue of 3.6V or 5V using a suitable precesion voltage divider at the input and accomodating the same in the software! This could reduce one majour constraint. So far as DAC goes either a similar approach could be adapted or external DAC's could be resorted to as having all the requirements of ADC's and DAC's in one package seems critical.
