DSPIC33EP32GP504T-I/PT

Microcontrollers Overview

The dsPIC33EP32GP504T-I/PT is a 16-bit Digital Signal Controller from the Microchip dsPIC33EPXXXGP50X family. It features a dsPIC33E CPU core with 32 KB of program Flash memory and 4 KB of data RAM. The device operates at clock frequencies up to 70 MIPS within an industrial temperature range of -40°C to +85°C, powered by a supply voltage between 3.0V and 3.6V. It is housed in a 44-pin TQFP package.

Microcontrollers Feature Summary

• High-speed PWM generation with independent timing and fault inputs for motor control applications
• Advanced analog capabilities including configurable ADC resolution and Charge Time Measurement Unit
• Flexible communication interfaces supporting CAN, SPI, I2C, and UART protocols

Microcontrollers Applications

• Brushless DC (BLDC) and Permanent Magnet Synchronous Motor (PMSM) drives
• AC Induction Motor (ACIM) and Switched Reluctance Motor (SRM) control
• Power factor correction (PFC) and lighting systems
• Industrial inverters and AC/DC converters

Microcontrollers Procurement Notes

Verify that the ordering suffix 'I' corresponds to the industrial temperature range (-40°C to +85°C) and 'PT' indicates the 44-lead thin quad flat pack package. Confirm the specific tape-and-reel quantity matches your production requirements. Ensure the component meets AEC-Q100 Grade 1 qualification standards if automotive application is intended.

Microcontrollers Selection Notes

Select this model when a balance of processing speed and peripheral richness is required for motor control. The GP504 variant offers sufficient memory for complex algorithms while providing dedicated hardware PWM and analog modules. Consider the TQFP package for standard surface-mount assembly processes requiring robust thermal dissipation.

Microcontrollers Part Context

This controller belongs to the dsPIC33EP series, designed for high-performance digital signal processing tasks. It integrates a 16-bit CPU with dual 40-bit accumulators and single-cycle multiply-accumulate units. The family supports code-efficient C and Assembly architectures, enabling efficient execution of control loops and signal processing routines.

Microcontrollers Replacement Considerations

Cross-reference with other devices in the dsPIC33EP32GP504 family or the PIC24EP32GP204 series for pin-compatible alternatives. Verify memory size and peripheral availability match before substitution.
