Infineon Interview Questions- General for freshers

-

1. Basic digital electronics, mostly based on timers, counters and FFs.

2. Microcontroller- ARM architecture/ 8051

3. Interrupts,  NVICs, memory organization in uC, watchdog timers, PWMs etc.

4. Basic C programming, like masking, nested loops, bitwise operations

5. Op-Amps and their usage in uC

6. ADC and DACs internal structure and working 

7. Any projects you've worked on!

8. Communication protocols like CAN, IIC, SPI, UART etc. And their internal functioning!

9. Clocks - difference between PLL, FLL, and how to create clock divider circuit (both odd division and even) and how to upscale 

10. Power electronics - buck, boost, LDOs and their internal working! 

11. Ripple currents and use of inductors, also, decoupling capacitors

12. Difference between single ended lines and differential pairs and why we use them

13. Some basic validation procedure including PVTF flow
