DSPIC33EP32GP504T-E/PT

Microcontrollers Overview

The dsPIC33EP32GP504T-E/PT is a 16-bit Digital Signal Controller from the dsPIC33EPXXXGP50X family, manufactured by Microchip Technology. It features a 32 KB Flash program memory and 4 KB RAM within a 44-pin TQFP package. The device operates on a 3.0V to 3.6V supply voltage and supports clock frequencies up to 70 MIPS at -40°C to +85°C, or up to 60 MIPS at -40°C to +125°C. It includes two UARTs, two SPI modules, two I2C modules, and an ECAN module.

Microcontrollers Feature Summary

• Features a 16-bit dsPIC33E CPU core with code-efficient architecture for C and Assembly programming.

• Supports advanced analog functions including configurable ADC and Charge Time Measurement Unit (CTMU).
• Provides remappable peripherals via Peripheral Pin Select (PPS) for flexible I/O configuration.

Microcontrollers Applications

• DC/DC and AC/DC power conversion systems
• Brushless DC (BLDC), PMSM, and AC induction motor drives
• Active Power Factor Correction (PFC) circuits
• Automotive electronics requiring AEC-Q100 Grade 1 qualification

Microcontrollers Procurement Notes

Verify the specific ordering suffix 'T-E/PT' to confirm the tape-and-reel packaging, extended temperature range (-40°C to +125°C), and automotive-grade AEC-Q100 REVG qualification. Ensure compatibility with the required 44-pin TQFP footprint during PCB layout. Cross-reference the manufacturer's latest datasheet DS70000657J for any errata or design updates relevant to this component revision.

Microcontrollers Selection Notes

Select this controller when a 16-bit DSP architecture is required alongside general-purpose microcontroller features. It is suitable for applications needing precise motor control PWM generation and robust communication interfaces like CAN and LIN. Consider the 32 KB Flash size for complex algorithm storage and verify that the 44-pin TQFP package fits the mechanical constraints of the target enclosure.

Microcontrollers Part Context

This component belongs to the dsPIC33EPXXXGP50X General Purpose family, designed for cost-sensitive applications requiring DSP performance. It shares the same core and peripheral set as the MC20X/50X Motor Control families but lacks dedicated motor control PWM channels in the GP variant. The 'E' suffix denotes the extended industrial temperature range, while '/PT' specifies the surface-mount TQFP package type.

Microcontrollers Replacement Considerations

Direct pin-compatible substitutes within the same package include other devices from the dsPIC33EP32GP504 series with different suffixes (e.g., /ML for QFN). For functional equivalents with larger memory, consider the dsPIC33EP64GP504 or dsPIC33EP128GP504 variants, ensuring peripheral availability matches the application requirements.
