DSPIC33EP64GS504-I/ML

dsPIC33EP64GS504-I/ML is Microchip’s 16‑bit dsPIC33E microcontroller with an integrated DSP engine for real‑time control and signal processing. It combines a 16‑bit dsPIC core (DSP MAC) with MCU peripherals for motor control, power electronics, audio, and sensor DSP tasks. Typical performance is up to about 40 MIPS at standard clock speeds. Memory options on this device include roughly 64 KB of Flash and about 8 KB of RAM (sizes vary by part family).
Key peripherals include dual 12‑bit ADCs, multiple PWM channels with dead‑time, capture/compare, DAC, comparators, op‑amps, multiple timers, and Configurable Logic Cells (CLC). Communication interfaces typically cover UART, SPI, I2C, and CAN, with some variants offering USB FS. Peripherals also feature Peripheral Pin Select (PPS) for flexible pin mapping, DMA, and robust reset and watchdog options.
I/ML indicates Industrial temperature range with a lead‑free (ML) packaging option; verify exact package and features in the datasheet. Development is via MPLAB X IDE with the XC16 compiler.
