DSPIC33EP16GS505-I/PT

Microcontrollers Overview

The dsPIC33EP16GS505-I/PT is a 16-bit Digital Signal Controller from the dsPIC33EPXXGS50X family, designed for digital power applications. It features a 16-bit dsPIC33E CPU with dual 40-bit accumulators and operates up to 70 MIPS at -40°C to +85°C. The device includes 16 Kbytes of Flash program memory and 2 Kbytes of RAM in a 48-pin TQFP package. Key peripherals include five high-speed PWM generators, a 12-bit ADC with four dedicated cores, two Programmable Gain Amplifiers (PGA), and four rail-to-rail comparators.

Microcontrollers Feature Summary

• High-Speed PWM Generators: Five independent PWM generators with 1.04 ns resolution support center-aligned, redundant, complementary, and true independent output modes for AC/DC, DC/DC, inverters, PFC, and lighting applications.
• Advanced Analog Features: Includes a high-speed 12-bit ADC module with four dedicated SAR cores, two Programmable Gain Amplifiers (PGA) with selectable gains, and four rail-to-rail comparators with integrated DACs for precise signal conditioning.
• Interconnected Peripherals: Flexible trigger options allow direct interaction between PWM, ADC, and comparators, reducing CPU intervention for cycle-by-cycle current mode control and current reset modes.

Microcontrollers Applications

• Digital Power Supplies
• Motor Control Systems
• Solar Inverters

Microcontrollers Procurement Notes

Verify the specific ordering suffix '-I/PT' corresponds to the Industrial temperature range (-40°C to +85°C) and TQFP-48 package. Confirm AEC-Q100 Grade 1 qualification requirements if automotive compliance is needed. Check for any silicon errata sheets or programming constraints before finalizing the design.

Microcontrollers Selection Notes

Select this component when a 16-bit DSC with extensive analog integration is required for power conversion. The dsPIC33EP16GS505 offers a balance of processing speed and peripheral density suitable for complex control loops. Ensure the 48-pin TQFP package fits the board layout and that the 16 KB Flash size meets application code requirements.

Microcontrollers Part Context

This device belongs to the dsPIC33EPXXGS50X family, which specializes in interconnected high-speed PWM, ADC, PGA, and comparator modules. The family targets digital power applications requiring tight synchronization between analog sensing and pulse generation without heavy CPU overhead.

Microcontrollers Replacement Considerations

Other members of the dsPIC33EPXXGS50X family may serve as alternatives depending on memory size and pin count requirements. Verify pin compatibility and peripheral availability when considering cross-model replacements within the same series.
