DSPIC33EP256GM706-H/PT

Microcontrollers Overview

The dsPIC33EP256GM706-H/PT is a 16-bit Digital Signal Controller from the dsPIC33E family, featuring 256 KB of Flash program memory and 32 KB of RAM. It operates at up to 70 MIPS within the industrial temperature range (-40°C to +85°C) and up to 60 MIPS in the extended range (-40°C to +125°C). The device utilizes a modified Harvard architecture with a 16-bit data path and 24-bit instructions. Key peripherals include high-speed PWM modules, dual ADCs, four Op Amps/Comparators, CAN interfaces, and a Charge Time Measurement Unit (CTMU).

Microcontrollers Feature Summary

• Features a high-performance 16-bit dsPIC33E CPU optimized for code efficiency and single-cycle multiply-accumulate operations.
• Incorporates advanced analog capabilities including configurable 10-bit or 12-bit ADCs and integrated operational amplifiers.
• Provides flexible motor control support via high-speed PWM generators with programmable fault inputs and dead time.
• Supports robust communication through multiple UART, SPI, I2C, and CAN modules with remappable pin functionality.

Microcontrollers Applications

• Brushless DC (BLDC), PMSM, ACIM, and SRM motor drives
• DC/DC and AC/DC power converters
• Active Power Factor Correction (PFC) circuits
• Industrial lighting systems

Microcontrollers Procurement Notes

Verify that the -H suffix corresponds to the extended temperature grade (-40°C to +125°C) as specified in the official Microchip product identification system. Confirm package availability and lead times directly with authorized distributors, as standard documentation may reference general family specifications rather than specific ordering suffix constraints.

Microcontrollers Selection Notes

Select this component when an application requires deterministic real-time performance combined with integrated analog signal conditioning. The inclusion of Op Amps and CTMU reduces external component count for sensor-based designs. Ensure the 64-pin TQFP package meets board space requirements and that the voltage range aligns with the 3.0V to 3.6V operating specification.

Microcontrollers Part Context

This device belongs to the dsPIC33EPXXXGM3XX/6XX/7XX family, which integrates core-independent peripherals to offload the CPU. The GM7xx series specifically adds CAN module support compared to the GM3xx variants. It serves as a bridge between standard MCUs and higher-end DSPs, offering dedicated hardware acceleration for control loops without requiring complex external interfaces.

Microcontrollers Replacement Considerations

Direct replacements within the same package and pinout include other members of the dsPIC33EP256GM7xx series, such as the dsPIC33EP256GM706-I/PT for industrial temperature ranges. Cross-family migration to dsPIC33CK or dsPIC33AK series requires schematic redesign due to architectural differences.
