Parallel Slave Port (PSP)
The Parallel Slave Port (PSP) is a feature found in some Microchip PIC microcontrollers, particularly in the PIC16 and PIC18 families. It allows the microcontroller to interface with external devices in a…
Difference between ARM and Thumb states (ARM vs. thumb)
In ARM-based processors, ARM and Thumb states serve different purposes, primarily affecting code size and memory efficiency. The ARM state operates with a full 32-bit RISC instruction set, while the…
BJT – Bipolar Junction Transistors

Difference between microprocessors and microcontrollers
MicroprocessorMicrocontrollerA microprocessor requires multiple external support devices such as ROM, RAM, Serial interface, Timers, and I/O ports. These components are connected via a system bus, which includes an address bus,…
