DSPIC33CH128MP203-E/M5

Microcontrollers Overview

The dsPIC33CH128MP203-E/M5 is a dual-core 16-bit digital signal controller from the dsPIC33CH family. It features a Master Core operating up to 90 MIPS and a Slave Core up to 100 MIPS, with 128 Kbytes of Flash for the Master and 24 Kbytes of PRAM for the Slave. The device includes four ADC modules (one Master, three Slave), high-resolution PWM, and multiple communication interfaces including UART, SPI/I2S, and I2C. Operating conditions range from -40°C to +125°C at 3V to 3.6V.

Microcontrollers Feature Summary

• Dual-core architecture enabling independent code execution on Master and Slave cores
• Integrated analog peripherals including multiple ADCs, DACs, and comparators
• High-resolution PWM generation with fine edge placement capabilities
• Support for CAN FD and SENT protocols alongside standard serial interfaces

Microcontrollers Applications

• Motor control applications such as BLDC, PMSM, and ACIM drives
• Power supply systems including DC/DC converters and UPS units
• Automotive electronic control units requiring functional safety compliance
• Industrial automation systems utilizing precise timing and control loops

Microcontrollers Procurement Notes

Verify the specific suffix 'E' indicates extended temperature range operation up to +125°C. Confirm the '/M5' designation corresponds to the 36-pin UQFN package type. Ensure compatibility with required programming tools and development environments for dual-core debugging support.

Microcontrollers Selection Notes

Select this model when dual-core processing is required to separate time-critical control tasks from system management functions. Consider the 36-pin footprint if space constraints exist. Evaluate peripheral availability against application needs, noting that certain modules are exclusive to either the Master or Slave core.

Microcontrollers Part Context

This component belongs to the dsPIC33CH128MP508 family, which offers various pin counts and memory configurations. The MP203 variant specifically lacks CAN FD hardware but retains other advanced features like SENT and high-speed analog modules. It serves as a mid-range option within the series balancing performance and interface requirements.

Microcontrollers Replacement Considerations

Direct substitutes include other members of the dsPIC33CH128MP20X family such as the dsPIC33CH128MP205 or dsPIC33CH128MP206, provided pin count and peripheral requirements match. Verify software compatibility and register mapping differences between variants before implementation.
