A typical B.Tech syllabus for Microprocessors and Microcontrollers includes topics like 8085 and 8086 microprocessors, 8051 microcontroller, interfacing with peripherals, and assembly language programming. You'll also find coverage of Arduino and Raspberry Pi, along with IoT applications. The syllabus often includes practical components like interfacing with LCDs, keyboards, and sensors. 

Microprocessors:

1. 8085 Microprocessor:
   Architecture, pin configuration, bus organization, instruction set, addressing modes, memory and I/O interfacing, interrupts.
2. 8086 Microprocessor:
   Architecture, register organization, memory segmentation, instruction set, addressing modes, assembly language programming, interrupts. 

Microcontrollers:

• 8051 Microcontroller: Architecture, pin configuration, memory organization, I/O ports, addressing modes, instruction set, timers, counters, interrupts, serial communication. 

Interfacing and Applications:

• Interfacing with peripherals: LCD, keyboard, external memory, ADC, DAC, DC motor, stepper motor. 
• Serial communication: UART, I2C, SPI. 
• IoT applications: Interfacing with sensors (temperature, humidity), playing tones and melodies using Arduino, controlling speed and direction of motors. 
• Arduino: Introduction to the Arduino platform, creating programs, using libraries, and interfacing with sensors and devices. 
• Raspberry Pi: Introduction to Raspberry Pi, programming environment (Python), GPIO pins, interfacing with devices and sensors. 
• Assembly Language Programming:
• Assembly language programming for both microprocessors and microcontrollers, including writing programs for arithmetic operations, logical operations, data manipulation, and control flow.
