We are looking closely at the STMicroelectronics STM32F205RBT6 for a new ARM7 based auto board design.  I see atmel has some options and  I'd much prefer atmel.

 

The requirements are as follows.

 

  1. We have a need to communicate over Can on 2 buses simultaneously.
  2. We need to use a bootloader USB.
  3. The chip much have eeprom.
  4. And a program size > 128k.
  5. We only need about a 16mhz clock.

 

We'd like to stay near $4 a chip @ 1k volume. Anyone have a recommendation on the atmel side?

 

p.s. Is STMicroelectronics compatible with avr32program, so avrstudio 7 would work?

STM32F205RBT6 for a new ARM7

That is not an ARM7!

No!

 

AVR is entirely proprietary to Atmel.

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

Right I forgot we switched to Cortex®-M3. Still would prefer something atmel based (SAM3 family maybe). SAM3X price is a bit high.

ATSAM3X4C is looking like a pretty good match. Did microchip buy out atmel?

Was that a joke without an emoticon?

 

Yes.

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.
