DSPIC33CK32MC102-I/SS

Microcontrollers Overview

The dsPIC33CK32MC102-I/SS is a 16-bit Digital Signal Controller from the dsPIC33CK64MC105 family, manufactured by Microchip Technology. It features a high-performance CPU with a 16-bit data path and 40-bit accumulators, operating at frequencies up to 100 MHz within the -40°C to +125°C temperature range. The device integrates 32 Kbytes of Flash program memory and 8 Kbytes of SRAM data memory. Key peripherals include four high-speed PWM pairs, a 12-bit ADC with up to 3.5 Msps conversion rate, three operational amplifiers, and multiple communication interfaces such as SPI, I2C, and UART.

Microcontrollers Feature Summary

• Integrates a high-performance 16-bit DSP RISC CPU with single-cycle multiply and accumulate capabilities for efficient digital signal processing.
• Provides high-speed pulse width modulation with up to 2 ns resolution and dedicated fault inputs for motor control applications.
• Includes a 12-bit analog-to-digital converter with flexible trigger sources and integrated digital comparators for precise signal acquisition.
• Features robust safety mechanisms including flash error correcting code, RAM built-in self-test, and dual watchdog timers.

Microcontrollers Applications

• Brushless DC (BLDC) and Permanent Magnet Synchronous Motor (PMSM) drives
• AC Induction Motor (ACIM) and Switched Reluctance Motor (SRM) control
• Power factor correction (PFC) and DC/DC converter systems
• Industrial lighting and AC/DC power supply designs

Microcontrollers Procurement Notes

Verify the specific suffix 'I/SS' corresponds to the industrial temperature range (-40°C to +125°C) and SSOP-28 package configuration. Confirm that the ordered component matches the dsPIC33CK32MC102 variant with 32K Flash memory rather than other family members like the 64K or 128K variants. Ensure compatibility with the required voltage supply range of 3.0V to 3.6V for proper operation.

Microcontrollers Selection Notes

Select this controller when a compact 28-pin solution is required for motor control or power management applications. It is suitable for designs needing high-resolution PWM and fast analog conversion without the pin count of larger packages. Consider the available peripheral set, including three op amps and four SCCP modules, against system requirements for sensor interfacing and timing generation.

Microcontrollers Part Context

This component belongs to the dsPIC33CK64MC105 family, which unifies MCU control attributes with DSP computational power in a single core. The family supports functional safety standards including IEC 60730 Class B and ISO 26262 ASIL B. Devices in this series are qualified under AEC-Q100 Grade 1 specifications for automotive reliability.

Microcontrollers Replacement Considerations

Other devices within the dsPIC33CK64MC105 family, such as the dsPIC33CK64MC102, share identical pinouts and peripheral sets but offer increased memory capacity. Substitution requires verification that the additional memory does not impact boot time or configuration bit settings. Ensure the replacement part maintains the same package type and temperature rating.
