DSPIC33CH512MP206-E/MR

Microcontrollers Overview

The dsPIC33CH512MP206-E/MR is a dual-core 16-bit digital signal controller from the dsPIC33CH family, housed in a 64-pin TQFP/QFN package. It features a main core operating up to 90 MIPS and a secondary core up to 100 MIPS. The device includes 512 Kbytes of program flash with ECC and 48 Kbytes of data RAM with BIST for the main core, alongside 72 Kbytes of PRAM and 16 Kbytes of data RAM for the secondary core. Operating conditions range from -40°C to +125°C at 3V to 3.6V. Key peripherals include four ADC modules, three DAC/Analog Comparator modules, three PGA modules, two UARTs, two SPI/I2S modules, two I2C modules, one QEI, four CLCs, and high-resolution PWM capabilities.

Microcontrollers Feature Summary

• Dual-core architecture with independent peripherals and configurable shared resources for parallel processing.
• High-resolution PWM generation with fine edge placement suitable for advanced motor control and power supply applications.
• Integrated safety features including ECC, MBIST, and functional safety readiness for automotive and industrial standards.
• Advanced analog subsystem comprising multiple ADCs, DACs, comparators, and programmable gain amplifiers.

Microcontrollers Applications

• Brushless DC (BLDC), PMSM, SR, and ACIM motor control
• DC/DC converters and AC/DC power supplies
• Uninterruptible Power Supply (UPS) systems

Microcontrollers Procurement Notes

Verify the specific suffix 'E' indicates extended temperature operation (-40°C to +125°C) as per Microchip documentation. Confirm the 'MR' suffix corresponds to the 64-pin TQFP or QFN package variant. Ensure compatibility with MPLAB X IDE for development. Check for any current errata sheets related to silicon revision before finalizing procurement.

Microcontrollers Selection Notes

Select this component when dual-core processing is required for complex control loops and communication handling simultaneously. The absence of CAN FD distinguishes it from the MP50x variants; choose this model if CAN FD is not needed but high-performance motor control and analog processing are priorities. Evaluate pin count requirements against the 64-pin footprint.

Microcontrollers Part Context

This device belongs to the dsPIC33CH512MP508 family, specifically the MP20x sub-family which lacks CAN FD modules. It shares the same core architecture and memory map as the MP50x series but offers different peripheral configurations tailored for applications where CAN FD is unnecessary. It competes in the high-performance 16-bit DSC market for industrial and automotive sectors.

Microcontrollers Replacement Considerations

Direct replacements within the same family include dsPIC33CH512MP208-E/MR (80-pin) or dsPIC33CH512MP205-E/MR (48-pin). For single-core alternatives, consider the dsPIC33CK series. Verify pinout compatibility and peripheral availability when substituting.
