Hi Shahriari,

I think the Kinetis K50 series can meet your requirements. Attached is K50 Family Product Brief which provide a lot information of K50 series and you can browse it.

Freescale also provide Glucose Monitor application based on K50 for customer.

First link is about Continuous Glucose Monitor and the second is about Pulse Oximeter Fundamentals and Design

Is there any other MUC that I can use instead of the Kinetis series?

Hi Shahriari,

Does not the K50 series MCU meet your requirement? If not, you can choose K60 or K70 as replacement.

The K50 MCU family provides designers with an analog measurement engine consisting of

integrated operational and transimpedance amplifiers as well as high-resolution ADC and DAC

modules and is very suitable for medical measurement.

Hi Shahrzad,

K50 Family is suited for medical applications. Here is the K50 Family block diagram; as you can see the analog part has ADC, DAC, OPAMP and TRIAMP

And here is the Glucose Meter Fundamentals and Design AppNote: http://cache.freescale.com/files/microcontrollers/doc/app_note/AN4364.pdf?fpsp=1&WT_TYPE=Application%20Notes&WT_VENDOR=F…
