A highly specialized microcontroller is used in a robotic arm designed for precision manufacturing. The arm has 6 degrees of freedom, and each joint is controlled by a servomotor. The microcontroller receives joint position commands in the form of Pulse Width Modulation (PWM) signals.

The servomotors operate on a PID control loop to achieve precise positioning. The PID constants (Kp, Ki, Kd) for each joint are stored in the microcontroller's EEPROM. Each joint's feedback is provided by a 12-bit absolute encoder.

The robotic arm also has a sensor array that includes an accelerometer, a gyroscope, and a magnetometer, all communicating with the microcontroller via I2C protocol. The microcontroller has to process data from these sensors to maintain the arm's stability and to correct for any deviations in real-time.

In addition, the arm must execute a specific task sequence within a tolerance of 0.1mm precision. This task involves picking up objects from a conveyor belt moving at a speed of 0.5 m/s. The microcontroller calculates the exact position of each object using machine vision processed through an FPGA.

Given that:

• The servomotor's PWM frequency is 50 Hz and each PWM period is 20ms, where the pulse width varies from 1ms to 2ms to represent 0 to 180 degrees of rotation.
• The base address in EEPROM for storing PID constants is 0x200, and each joint's PID constants occupy 16 bytes.
• The FPGA used for machine vision processing has a model number ending in A7F9.

Calculate the unique identifier by concatenating:

1. The hexadecimal representation of the microcontroller's EEPROM memory address that stores the PID constants for the third joint.
2. The 12-bit binary feedback value from the absolute encoder for the fifth joint at its mid-range position.
3. The last four hexadecimal digits of the FPGA's model number.
