Hi

I am currently doing a little research about microcontroller chips and I would appreciate to hear your valuable information. I need to know which kind of microcontroller chip have you been used in your previous projects and which chips are you planning to use in the future. Please just type the microcontroller chip and explain your reason of using it.

Thank you in advance

Maverickmax

16f628A, 16f877A

started with 16F628 due to there being so many tutorial/info on the net about is (it is an almost direct replacement for the 84). didnt have enough i/o ports so moved onto the 877.

I have used AVR, LPC930, Atmel ARM AT920 (?), M16C/62P, H8S series.

Moving forward, the new Freescale MC9S08RD8 looks cheap.

i usually used microchip ( 12F629 12F675 16F84A 16F74 16F676 16F877A 18F452 ) because other then microchip and atmel nothing is available in my country ( bangladesh) Very Happy

well i recently got a renesas skp 16MC and i m liking it

HI

I have used many type of microcontroller's started long time ago with the 8085 moved to 8051,pic,zilog,XA,AVR,Psoc...

And now I'm working with the MSP430 from TI and the LPC21xx from philips

I would like to recomed the MSP430 - i have found it best for mid range application and the LPC for More havy one and as the best replacement for the 8051

All the best

Use the "helped me" button instead of posting empty thank you messages like this.
Please read forum rules.

Anyway, I started on with PIC16F84 / 16F628 because we were bound to use this for a university project.
Later on I took a MCU course at the same university, and here we used the AVR family.
Since then I have used the AVR family. I prefer AVR over the PIC family. BOth becuase I like this MCU family better and I also had to use it for a task where the PIC was not fast enough. But the main reason why I prefer AVR over PIC is because I find the software tools much better and produces more bug free code than PIC compilers. And AVR compilers in general are cheaper than PIC compilers, you can even get a free GNU C compiler for AVR that is still a good quality compiler.
A good thing about AVR is the great STK500 kit, you can't get anything as good as this for any other microcontroller. Eespcially for beginners this is a good thing.

Hi!

I use Texas Instruments MSP430, because my project needs very low power consumption. I plan to use Renesas M16C in projects that require more processor power.

I dont think this is really usefull info unless we specify what we used it for so you can get an idea what the strong points are for each processor. I mean posting that i always use a P4- 3 Ghz, while i only switch a led with it isnt very usefull info is it?

I have used the 89C51RD2 from atmel for simple timebased projects. I used it for a data generator that had to calculated with a 3 digit number behind the "." and that still worked fine. Now im driving a 320x240 gfx display and one screen only takes about 100ms on 12Mhz. Good thing about the processor is that it has 64K flash and 1K extended RAM on board. You can also program it directly from your PC with a MAX232 buffer circuit, so REAL ISP. Bad thing can be 8 bit but Atmel has the AVR and ARM7 chips also so easy to migrate later on i think.

I user ATMEL AVRMega in my previous project because it is useful and suitable for the objectives.

In the future, I have no specific chip yet. It depends on what kinds of project that i want to do with and also if i think about mass production. I would prefer a cheaper price chip for need funciton.

I have started with PIC16F628/876 and AT90S2313/ATmega16. They were excellent for some simple projects (mainly timing applications).

Then I turned to 16 bit MSP430 family which allowed handling large numbers more easely, reducing development time (for the same type of projects)

Now I'm working on some complex projects which needs large amount of resources (both computational time and memory) so I'm using 32 bit microcontrollers (Fujitsu FR50 family)

Previous uC - pic16F84

Reason - Many application note available and a good starting uC for beginner with so little instructions in assembly and most important of all, a very active PICLIST forum. Of course equally important is that we can get it here at usd3.80. Use if for 1 year for a phone project and some simple control project.

Previous uC - 908JL3 Motorolla

Reason - Major suppliers push for this uC at that time, to the extent that they borrow us the development board for the duration of a project. Besides, it seems logical to use the 908 series since they have a quite complete range of uC from those 8 pins to those GP32 range with high nos of I/O and 'fortified' with usb,rf or CAN. Use it for automotive projects since it has a slightly better EMI immunity.

Current uC - 89S52

Reason - current employer uses 8051 controllers. Cheaply available at usd1.3 for low volume. and eversince using 8051 assembly, got hooked with it for it's simplicity.

Anyway, i am an assembly writer as such, i am not able to appreciate the development environment (ide) provided by various controllers, which i think should be taken into account.

Future uC - AVR or ATmega

Reason - try to move on to better things, but of course subject to chip availability in local market and cost of development board and availability of free C compiler like in AVR.

Hope this helps.

I am using the PIC 18f6720.

This was chosen as we are using it for another similar project, and it is a good fit for our requirements.
It was chosen for the other project because at the time it was one of the top of the line PIC's that ran quick anough and had enough IO.

I have also used PIC 16f84 for some small stuff, mainly cos we had some laying around.

Hi. I'm currently using an AVR family. I started from them, and there were people who could help. Besides, in my first serious project at work I had to use AVR and nothing else. And I like it!
For some future work I consider Cygnal C8051Fxxx controllers mainly because of USB 2.0 integrated features.
I was ready to start to use Winbond '51 controller family but I experienced difficulties to get it in my area.

hi
i recently switched to atmel's ATmega(AVR).
because of it's features like onchip ADC,RTC,Analog comprator,PWM Channels,TWI interface(I2C),EEprom and its simple and lowcost programmer and emulator(JTAGICE).
finally for it's low cost

Code:

Hi,
Past: MC680x, 68HCxx, many '51 clones, MSP430, MC68K, 808x and Alpha.

I used many different uP families, but it always cost me time to switch, learn, forget. It is not a good idea to switch between processors every now and then.

Therefore .....

Future: Self-designed SoftCore uP + FPGA.
There are many advantages.
Once the uP is created I can use it for all works in the future.
I know my uP very well.
Redesigning or resizing the project is a snap of a finger.
I can always pick a larger FPGA to fit the entire system with all gates,
FFs and other stuff.
I can have just one set of design tools.
All extra functions may be added at will as either processor extensions
or peripherals, still in a single FPGA chip.

That's a very abbreviated motivation, but I think that most of us have always wanted to design a processor suiting one's fancies, instead of coping with numerous ( annoying and illogical sometimes ) tradeoffs of commercialy available production, and that is the whole point.

i have used only ATMEL MCUs till today.
i have started to learn with AT89C51.
i am using right now AT89S52 MCU.
i am planning to use UPGARDED MCU from ATMEL or from PIC.
i dont know which one i'll use or not but i am planning to learn more and more..
finally thats sure i'll stick with ATMEL atleast because it has wide range of MCUs and also available in market easier than other as per my knowledge and experience.

Thank you

hi

ARM7 based 2368
reason,the company i worked in wants to move on to 32 bit architecture,with lot of peripherals on single chip,good enough ram,upto 72 mhz cpu clock frequency usb, dma,ethernet ,and lot more

AVR series
most of avr are available locally in Pakistan and are cheap,tools are easy to find.

ATMEL 89c51,8952,89s52
8051 based controllers were the start points in pakistan,included in course study
in most institutes,very cheap and most commonly availble.

I've used the ff µCs:
8051

Reason: Easy to use, low cost, diverse chips availabe.

LPC200
Reason: Powerful, low power, peripheral rich,

Future:
Arm9

The only reason someone would use an ancient 8051 is because they can't get anything else. AVR or PIC are much better choices.

this is the first time i had taken up a µc proj...............was using an ATMEL in AT89S8252..................i would prefer using these ones because of its FLASH memory!!!
