There was some recent discussion of having an ARM based Arduino which runs at 5V. Before I embark on a design, does anyone know if such a thing is already available? Searching of google reveals nothing.
To be clear, I mean a device that has a supply voltage of 5V and all IOs are 5V, not just a device that has some 5V tolerant IOs. An additional requirement is that the devices are widely available through retail distributors like RS, Farnell, Mouser, Digikey and not trade oriented ones. A bonus would be DIY friendly packages such as DIP or SOIC.
The second question is what chips are commonly available ? So far I have :
- NXP Kinetis E,L series
- Infineon XMC
- Cypress PSOC 4
- Spansion FM3
- Fujitsu MB9A110
As I have worked with NXP and Infineion devices, I would favour those. The MKL26Z128VLH4 looks nice, ARM Cortex M4 MCU, 48MHz, 128 kB Flash, 64-Pin LQFP.
