Other Parts Discussed in Thread: MSP430I2041
Hello Everyone,
Currently Im working with a MSP430AFE253 in which the configurations for the SD24 Converter ; SD24 Converter's Clock = 8MHz / 64 = 125KHz, with OSR Ratio = 512. Thus configuring the comb filter to have an attenuation band up to 125KHz with notches at the multiples of 244Hz.
Now we are facing some problems due to small memory of the AFE253 device and considering an update to a device with a higher RAM/Flash Memory; At least 2k RAM, 32K Flash is needed.
Firstly we considered MSP430I2041, thought it would be a good choice, but then we realized it has a fixed SD Converter clock speed of 1.1 MHz and OSR is only up to 256.
We want to keep the filtering provided by the COMB Filter in AFE253 same.
So Is there any way/workaround to achieve that with the I20xx series chips ?? Is it Possible to implement the missing part of the notch bank by software? Would it be the correct approach ?(given the MSP430 has no FPU)
If not I also appreciate a recommendation for some other chip series that comes with the SD Converter(SD16 is also OK.) that we can configure for the same filter parameters.
I wish for happy and healthy days, İlker.
