Introduction to 16-bit MCU technology designed with PIC24FJ256DA210

PIC24FJ256DA210 is a 16-bit MCU with a graphics controller (GFX) module that can interface with LCD displays and up to 96KB of data RAM. The PIC24FJ256DA210 high-performance CPU uses a modified Harvard architecture, with performance up to 16MIPS at 32MHz, an internal oscillator of 8MHz, a 17-bit x 17-bit single-cycle hardware multiplier, and a 32-bit x 16-bit hardware divider. The device operates at 2.2V-3.6V and digital inputs can reach 5.5V. It is mainly used in consumer electronics such as electric heating controls, cordless phones, remote control units, home appliances, sales terminals (POS) and portable medical devices such as blood glucose meters, blood pressure machines, portable ECGs, etc. This article introduces the main features, block diagrams of the PIC24FJ256DA210 series and the main features, block diagrams and detailed circuit diagrams of the PIC24FJ256DA210 development board.
