Q: Best Microcontroller for this job

Hello i was looking at using a atmel 8515 or a pic (not sure which variant yet) for a project.



The microcontroller will be connected to a max186 for analog aquisitions which will be stored in an eeprom, also looking at a keypad ,lcd,x10 and serial pc interface to configure the unit and download data from the eeprom..



one of my concerns on the 8515 is the price @10$ but i can use gcc, i don't want to get into assembly so i'd be looking at c / basic options for the pic (lowest cost possible )



Any suggestions?

TI MSP430? Can have the 12-bit ADC on-chip.

Unless you are aiming at high-volume production (in which case you should look wider than just 8515 and PIC): why bother about a few $? My first advice for a PIC/uC newbie is to choose a chip for which you can get help, that is far more valuable than the few $ price difference between het varous uC's.

PS don't take me wrong, I am a convinced PIC user. But I am not convinecd other people are wrong when they use AVR, 8051 or whatever.

Hi Chris, I think you can use Z8 encore microcontroller from zilog. It has 8 channel ADC , uart, 64Kb flash, price from 4$ to 12$, evaluation kit(C compiler & debug included) 30$. Check

The PICDEM Plus (or is that the PICDEM-2 Plus?) development kit has the following:

  • serial eeprom
  • LCD
  • MAX232 serial interface

Then connect the Max186 to the SPI of the PIC.

Then again, pretty much any microcontroller family you mentioned can do what you want. I don't know how much more powerful is the MAX186, but haven't you considered using internal eeproms and a/d channels that these microcontrollers have?

don't

Looks like single unit pricing. Try to get a free sample ? You should also look at the ATmega8515....
