Microchip Technology dsPIC33FJ64MC802 16-bit Digital Signal Controllers

Microchip dsPIC33FJ64MC802 16-bit DSCs

Microchip Technology dsPIC33FJ64MC802 high-performance 16-bit digital signal controllers (DSCs) provide 64KB of programmable Flash memory and 16KB of RAM. Microchip dsPIC33FJ64MC802 DSCs operate at up to 40 MIPS (at 3.0V -3.6V) and feature a modified Harvard architecture, a C compiler optimized instruction set, 16-bit wide data path, and 24-bit wide instructions. Microchip dsPIC33FJ64MC802 DSCs include an 8-channel hardware DMA (Direct Memory Access), five 16-bit timers, and 21 digital I/O pins.
