• Includes advanced analog peripherals such as a 10-bit ADC with four sample-and-hold channels and three comparators.
• Supports motor control applications with up to three PWM pairs and dedicated fault inputs.
• Provides flexible peripheral pin select (PPS) capabilities for remappable communication interfaces.

Microcontrollers Applications

• Inverter and PFC systems
• BLDC, PMSM, ACIM, and SRM motor drives
• UPS systems
• Capacitive touch sensing via CTMU

Microcontrollers Procurement Notes

Verify the specific suffix 'I/SS' corresponds to the required industrial temperature grade (-40°C to +85°C) and the 28-lead SSOP package format. Confirm that the AEC-Q100 Grade 0 qualification meets automotive reliability standards if applicable. Ensure the selected variant aligns with the necessary program memory size and I/O count requirements for the target design.

Microcontrollers Selection Notes

Select this component when a balance of moderate flash memory capacity and robust motor control features is required. The GP series offers general-purpose I/O flexibility compared to the MC series. Consider the 28-pin SSOP package for space-constrained surface-mount designs requiring through-hole compatibility alternatives like SPDIP during prototyping.

Microcontrollers Part Context

This part belongs to the dsPIC33FJ32(GP/MC)101/102/104 family, which shares a common core architecture but varies in pin count, memory size, and peripheral availability. The GP designation indicates general-purpose I/O configuration, while the MC designation typically includes additional motor control-specific pins. The '102' suffix denotes the 28-pin package variant with 32KB Flash.
