Hi everybody, I am looking for an ARM MCU with the following constraints (in the order of importance):
- 4 channel ADC with >= 500 k samples/s
- Price in 1k units < $1.50
- Frequency "as high as possible" but at least 32 MHz
- 1 UART
- RAM and Flash negligeable (1k RAM and 4k Flash would be largely enough).
I found the LPC2102 from NXP which almost hit the price mark. I also got the impression that the Stellaris chips from TI and the STM series don't come in my 'low cost range'.
Thanks for any comments and greetings from Germany M'
