DSPIC33CK256MP306-E/MR

Microcontrollers Overview

The dsPIC33CK256MP306-E/MR is a 16-bit Digital Signal Controller from the dsPIC33CK512MP608 family, housed in a 64-pin TQFP or QFN package. It features a single dsPIC33CK CPU core operating up to 70 MIPS at temperatures up to +150°C. The device includes 256 Kbytes of Flash program memory with ECC and 64 Kbytes of Data RAM. Key peripherals include five 12-bit ADC modules providing up to 20 conversion channels, eight High-Resolution PWM channels with 250 ps resolution, three UARTs, three SPI/I2S modules, three I2C modules, one Quadrature Encoder Interface (QEI), four Configurable Logic Cells (CLCs), and two SENT modules.

Microcontrollers Feature Summary

• Integrates high-resolution PWM generation with fine edge placement capabilities for precise control applications.
• Features advanced analog subsystems including multiple 12-bit SAR ADCs and hardware slope compensation DACs.
• Supports robust communication protocols via dedicated SENT modules alongside standard UART, SPI, and I2C interfaces.
• Includes safety mechanisms such as Error Correcting Code (ECC) for flash memory and RAM Memory Built-In Self-Test (MBIST).

Microcontrollers Applications

• Motor Control: BLDC, PMSM, SR, ACIM
• DC/DC Converters
• AC/DC Power Supplies

Microcontrollers Procurement Notes

Verify the specific suffix '-E/MR' against the manufacturer's official documentation to confirm the extended temperature range (-40°C to +150°C) and the 64-pin Thin Quad Flatpack (TQFP) or Quad Flat No-Lead (QFN) package type. Ensure that the absence of CAN FD modules aligns with system requirements, as this variant belongs to the 'No CAN FD' product family within the dsPIC33CK series.

Microcontrollers Selection Notes

Select this component when designing systems requiring high-speed digital signal processing without CAN FD connectivity. The device is suitable for applications demanding high-resolution timing control and multiple analog input channels. Consider the 64-pin form factor for space-constrained designs while ensuring compatibility with the available peripheral set, specifically the lack of CAN FD but presence of SENT and extensive PWM capabilities.

Microcontrollers Part Context

This controller belongs to the dsPIC33CK512MP608 family, which unifies motor control and power supply architectures. The MP30x designation indicates devices within this family that do not include CAN Flexible Data-Rate (FD) modules. This specific model offers a balance of processing power and peripheral density, targeting embedded control tasks where deterministic timing and analog precision are critical.

Microcontrollers Replacement Considerations

Direct substitutes within the same family include the dsPIC33CK256MP308 (80-pin) and dsPIC33CK256MP305 (48-pin). For pin-compatible upgrades or downgrades, verify the pinout differences between the 64-pin MR package and other variants in the MP30x series.
