DSP selection

Other Parts Discussed in Thread: TMS320F280049, TMS320F28375S, TMS320F28075

Hi Team,

One of my customers want to select a DSP to detect the residual current sensor, to achieve waveform sampling, FFT, waveform recognition, output action signal and other functions. It is expected that the sampling frequency is more than 50 kHz, the speed of digital to analog conversion is fast, and there are more than two ADCs and the size is about 1.5 cm × 1.5 cm

I can not find the sampling frequency option on the "Digital signal processors (DSP)" page so I posted the question here.
Also could you tell me why the filters on Microcontrollers page has the ADC option but the Processors page doesn't?

Beat Regards,

Hi, Tom,

It is not clear that if customer is looking for the DSP with ADC integrated solution. Could you be more elaborate on the set up?

Hi Rex,

We are looking for the DSP with ADC integrated solution.
Could you give us some advices?

Our C5000 and C6000 family of devices do not have integrated ADC

I would recommend looking at C2000 family of devices.

In the product selection matrix you should be able to find ADC and other features that maybe relevant for your application

the size limitation will keep this to devices with 100 pins or less

I would look at TMS320F280049 and related F28004x series which has a max of 100 pins, but also has smaller 7x7 devices.

There is also a higher end TMS320F28075 and TMS320F28375S that are available in 100-pin in their smallest configuration.

These are latest mid and high-performance DSP core based real-time controllers with integrated 12 and 16b high-speed ADC.
