I m using MSC1210Y5 for some application Features i require: 1. 1 uart(atleast) 2. Keil UV2 compatibility 3. Working on 5V supply 4. 12 Port pins(atleast) Can any of you suggest me some other controller that has the above mentioned features but on the same, costs less? MSC1210Y5 comes for 12$. That is very costly. Plus it has A/D section which lies redundant.
Can any of you suggest me some other controller that has the above mentioned features but on the same, costs less?<p> I'm sure there are dozens, if not hundreds of '51 derivatives out there that fit your requirements (and you didn't even specify how much ROM/XRAM you need or how fast the thing needs to run). And pretty much all of them will cost less than $12 (that's a really whopping price for a '51). May I suggest having a look at the device database ? http://www.keil.com/dd/search_parm.asp I m using MSC1210Y5 for some application Hm. I wonder what design decision prompted the use of an extremely expensive '51 derivate whose main feature is a high-precision ADC in an application that doesn't use the ADC.
Thanks Christoph when i compile the program this is what it shows: Program Size: data=63.0 xdata=0 code=1815 i hope that gives you a fair amount of idea Also i m not sure if i m using ROM!! Does the above information tell you anything about that? The link that you provided does not open!!
i hope that gives you a fair amount of idea Yes, it does. The program requires very little code and data memory, and no xram. You will have a huge number of derivatives to chose from and can probably find some that only cost a fraction of $12. The link that you provided does not open!! Oops, it looks like the forum is messing up links. It works if you type it in manually, or copy&paste the text (not the link) to your browser's address bar. Or go to Keil's main page, click on "Supported Microcontrollers", and then on "Parametric search".
The program requires very little code and data memory, and no xram. 1.How do we calculate the exact size in bytes or kB(of the hex file) by looking at "Program Size: data=63.0 xdata=0 code=1815". 2.Do ROM and Flash functionally mean the same?
2.Do ROM and Flash functionally mean the same? a) YES, they both hold the code to be executed b) NO, ROM can only be programmed once, flash can be programmed many times. c) the above is assuming that you speak of cases where ROM can be used, there are other uses for flash. Erik
