Scenario:

You are a junior computer engineer at a company that manufactures remote and radio control cars. Your R&D team is currently working on designing a new line of RC cars, which requires your knowledge on microcontrollers to make integral design decisions for upcoming products.

The design has the following base requirements:

Driving multiple DC motors for wheels

Buttons and joysticks on the controllers to accelerate, brake, reverse

Status LED's

Ultrasonic distance sensors for automatic braking

LCD display speedometer

You are required to determine an appropriate microcontroller for this project by performing a survey of the available options and justifying their applicability to the requirements by providing written reports on the asked tasks below to your supervisor.

Task $1$

Select a microcontroller from the following list of microcontrollers and, using the official datasheet, examine whether it meets the project requirements:

ATmega $328$

ATmega $2560$

PIC$16$F$877$

MK$20$DX$128$

Your examination$/$investigation should give an indication of the following metrics for your selected microcontroller:

Internal architecture and instruction set and instruction set architecture

Hardware interfaces including. $10$ ports $($number of $10$ ports and multiplexed capabilities, if present$),$ peripherals, $($including counters$/$timers$,$ ADCs, PWM$,$ SPI, UART, USART, $1^{2}C,$ as applicable$)$

Ensure that an explanation of the various functions of the microcontroller elements $($including a diagram$/$schematic$)$ is included in your report. Ensure that you cite all sources accordingly.
