Pin Count: TQFP packages are available with 32 to 256 pins, with varying lead pitch options such as 0.4 mm, 0.5 mm, 0.65 mm, and 0.8 mm. Higher pin counts are suitable for complex applications like microcontrollers (MCUs) and digital signal processors (DSPs), while lower pin counts work well for simpler integrated circuits.
