Goodday people,
Last week i finished a prototype of a product which uses an 8-bit Atmega2560 (running at 8Mhz) to sample data from 6 sensors, This data is then send to an online database. This prototype works good, however from the beginning i knew that the atmega had to go and make place for a microcontroller with more performance. Also the atmega lacks some peripherals that i need like more accurate timers.
Now i have been looking at 32-bit microcontrollers from STmicroelectronics, Atmel, NXP and Texas instruments. Mainly their ARM Cortex M0+/M3 and M4 based ones. But right now I am at a loss of which one to choose
During my search i am mainly focussing on the following:
1) low-cost, order quantity 50+ per order, so they need to be fairly cheap
2) If the vendor has an ultra low power consumption series (which they all do)
3) Free IDE with debugging capabilities en build in toolchain
Here are my findings:
Atmel SAM series -- Atmel Studio 7
TI
