Issues with PIC16F1503

[AAnkur]

I am using PIC16F1503 for my automotive application. I want to understand few things:-

1)I have gone through through the schematic present in the "https://ww1.microchip.com/downloads/en/DeviceDoc/50002295A.pdf". In this, PIC 16F1503 is not having external oscillator. I want to know if it is possible to connect external crystal oscillator to PIC16F1503. If yes, which are the pin numbers to which external crystal oscillator can be connected? What is the difference if micro-controller runs on external crystal or on internal oscillator?

2)How to implement UART on PIC16f1503 ? I did not find any RX and TX pin on PIC16F1503.
3)How to implement OTA on PIC16F1503?

Hello,

There seems not to be an UART in the PIC16F1503.

Read the full datasheet:

No UART posted in a few forums and has been answered.

I am using PIC16f1503 for my automotive application. It has all the features which I require.
Please suggest if PIC16f1503 is a good choice for automotive application or should I go for another micro-controller.

That would depend on the details you haven't included on what you are trying to do.
