PSLab Hardware V2 - new chip #79
There are better chips available for future versions of PSLab. One recommendation is LPC43S70FET256: 32-bit ARM Cortex-M4 + 2 x M0 MCU; 282 kB SRAM; Ethernet; two HS USBs; 80 Msps 12-bit ADC; configurable peripherals, AES engine
Because of the on board 80 MSPS ADC, 6 channel and so the oscilloscope function would be able to capture faster signals and 12 bit accuracy should be sufficient enough for most uses. It will still be available for at least 8 years, according to NXPs roadmap. The price is comparable to the STM32L4.
Hmmm but still, performance in terms of analog and digital sampling/signal generation is really down to the AD/DA converters and their specs. FPGA will drive the cost and design complexity up needlessly, compared to a MCU like the one suggested.
I don't see an application here that justifies the use for FPGA. Thoughts?
