Features & Applications

Microchip provides solutions for the entire performance range of 8-bit, 16-bit, and 32-bit microcontrollers, with a powerful architecture, flexible memory technologies, comprehensive easy-to-use development tools, complete technical documentation and post design-in support through a global sales and distribution network.16-bit PIC Microcontrollers & dsPIC Digital Signal Controllers. Microchip offers two 16-bit Microcontroller (MCU) families plus two 16-bit Digital Signal Controller (DSC) families that give you compatible options across a wide spectrum of price, performance and feature sets.

Common attributes among all 16-bit MCU and DSC families are pinouts, software, peripherals and development tools. Whether your design requires the lowest-priced 16-bit solution, the most powerful 16-bit MCU in the industry, or DSP capability, Microchip offers a broad range of products while preserving the compatibility that help save you time and money on subsequent designs.

The dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/X04, and dsPIC33FJ128GPX02/X04 CPU module has a 16-bit (data) modified Harvard architecture with an enhanced instruction set, including significant support
for DSP. The CPU has a 24-bit instruction word with a variable length opcode field. The Program Counter (PC) is 23 bits wide and addresses up to 4M x 24 bits of user program memory space. The actual amount of program memory implemented varies by device. A single-cycle instruction prefetch mechanism is used to help maintain throughput and provides predictable execution. All instructions execute in a single cycle,with the exception of instructions that change the program flow, the double-word move (MOV.D) instruction and the table instructions. Overhead-free program loop constructs are supported using the DO and REPEAT instructions, both of which are interruptible at any time.
