  The direct answer to your question is that there is no microcontroller that Parallax sells that is equal to the PIC16F690. On the other hand, it's a pretty meaningless question because it depends on what tasks you need to accomplish. The PIC16F690, like many of Microchip's microcontrollers, has a lot of functional units ... timers, UARTs, USARTs, ADCs, on-chip data EEPROM, on-chip flash program memory, on-chip SRAM. Very few applications need all that stuff (although some do). What functions do you need for this project? Parallax's SX and Propeller microcontrollers can provide some of those functions, but not all of them. They can also provide other functions that the PIC16F690 can't provide. So again, what do you need?

  You posted a program with no explanation (it would have helped). I assume that's something that is written for the PIC16F690 that you'd like to duplicate with a Parallax microcontroller.
  
  You've included no explanation of the program (it would have helped), but it looks like it manages a couple of 7-segment display digits and a relay and it reads one or two channels of analog data including the setting of a pot. It uses virtually none of the PIC16F690 functional units, just a channel or two of the ADC.
  
  The SX could certainly handle this application. The Stamps could probably handle it, but they're more expensive than a plain SX. A Propeller could handle it easily, but it would also be more expensive than an SX and mostly unused.
  
  Please do not post these open-ended questions unless you provide some explanation. It's impossible to give you a good answer without more information. Please provide some additional information in your original question. If you're honestly just curious about something, say so. If some project you're working on made you curious, say so and give a little information about what got you thinking.

  I've used the 16F690, it's a very nice chip. The $35 Microchip PICkit 2 will program it, or you could build your own serial port programmer for about $6. I use the Microchip ICD 2. Using an SX chip or a Propeller for that application will cost a lot more than using the PIC, as a external ADC will be needed, and the PIC is a very cheap device. The software will also need to be rewritten.

  For this application, it looks like you would not need an external ADC if you used an SX or Propeller since you're either measuring a pot's value or a relatively slowly changing voltage with 8-bit resolution.
  
  I agree, the PIC16F690 is a nice chip. I've also used the PICkit2 to program and experiment with it.
