The DSPIC33EP512GP504-I/PT is a 16-bit Digital Signal Controller (DSC) from Microchip in TQFP-44, running at 60 MIPS (120MHz effective with 2-cycle MAC) with 512KB Flash and 48KB SRAM. The dsPIC33E series combines a 16-bit MCU core with a DSP engine: the DSP engine provides a single-cycle 16×16 MAC (Multiply-Accumulate), 40-bit accumulator, barrel shifter, and modulo addressing, enabling efficient digital filter and control loop computation. The device includes: (1) High-Speed PWM module with 9 outputs, 1.04ns duty cycle resolution, dead-band, and auto-shutdown for motor control; (2) Two 12-bit ADCs at 1.1Msps each, with simultaneous sampling on 4 channels for 3-phase motor current measurement; (3) Three comparators with DAC references for overcurrent protection; (4) Two UARTs, two SPI ports, two I2C ports, and CAN 2.0B; (5) Four Configurable Logic Cells (CLC) for custom hardware logic without CPU intervention. The 512KB Flash supports 10,000 write/erase cycles. The auxiliary Flash (12KB) can store bootloaders separately from application code. The -I/PT suffix specifies industrial temperature (-40C to +85C), TQFP-44. The dsPIC33EP is the go-to choice for motor control (BLDC, PMSM, stepper), digital power supplies (PSU, UPS, solar inverter), and sensor signal processing.
