Product Overview
The DSPIC33FJ64GS606-I/PT is a 16-bit Digital Signal Controller with high-speed PWM, ADC and comparators. The PGECx and PGEDx pins are used for In-circuit Serial Programming™ (ICSP™) and debugging purposes. It is recommended to keep the trace length between the ICSP connector and the ICSP pins on the device as short as possible. The 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-bit wide and addresses up to 4M x 24 bits of user program memory space.
