DSPIC33FJ128GP804-H/ML

Microcontrollers Overview

The dsPIC33FJ128GP804-H/ML is a 16-bit Digital Signal Controller featuring a 40 MIPS CPU, 128 KB Flash program memory, and 16 KB RAM. It operates at 3.0V to 3.6V with an industrial temperature range of -40°C to +85°C. The device utilizes a 44-pin QFN package and includes an 8-channel DMA controller, Enhanced CAN module, dual UARTs, dual SPIs, I2C, ADC, and Audio DAC.

Microcontrollers Feature Summary

• Integrated 16-bit DSP engine with single-cycle multiplication and hardware divide capabilities for optimized signal processing performance.
• Hardware Direct Memory Access (DMA) controller enables data transfers without CPU stalls or overhead across multiple peripheral sources.
• Enhanced CAN module supports high-speed communication up to 1 Mbaud with full support for CAN 2.0B protocol standards.
• Programmable Peripheral Pin Select (PPS) allows flexible software remapping of input and output pin functions.

Microcontrollers Applications

• Industrial motor control systems requiring precise timing and signal processing
• Automotive networks utilizing the Enhanced CAN interface for reliable data transmission
• Audio equipment leveraging the integrated 16-bit dual channel Audio DAC
• Battery management systems requiring real-time monitoring via analog inputs

Microcontrollers Procurement Notes

Verify the specific suffix 'H' against official Microchip documentation to confirm extended temperature ratings or automotive qualification status. Ensure the ML package designation matches the required QFN footprint and pitch specifications for your PCB layout. Confirm RoHS compliance and export classification requirements prior to ordering.

Microcontrollers Selection Notes

Select this component when a balance of moderate memory capacity and advanced analog peripherals is required. The 44-pin QFN form factor suits space-constrained designs needing extensive I/O flexibility through PPS. Consider alternative family members if higher clock speeds or larger memory arrays are necessary for complex algorithmic loads.

Microcontrollers Part Context

This device belongs to the dsPIC33FJ128GPX04 product family within the broader dsPIC33F series. It shares architectural similarities with the dsPIC33FJ64GP804 but offers double the program memory capacity. The GP variant indicates general-purpose availability with standard peripheral sets suitable for diverse embedded applications.

Microcontrollers Replacement Considerations

Direct substitutes include other devices from the dsPIC33FJ128GPX04 family, such as the dsPIC33FJ128GP804 in different packages. Cross-referencing pinouts and peripheral availability is essential when considering upgrades to higher-memory variants like the dsPIC33FJ256GP710.
