Microcontrollers Procurement Notes

Verify the specific ordering suffix '-E/SS' corresponds to the industrial temperature range (-40°C to +125°C) and the 28-pin SSOP package as defined in the official datasheet. Confirm that the 'dsPIC33CK32MC102' designation matches the required 32 Kbyte Flash capacity rather than the 64 Kbyte variant. Ensure compatibility with the 3.0V to 3.6V supply voltage requirements for your design.

Microcontrollers Selection Notes

Select this component when a compact 28-pin solution is required for digital signal processing tasks. It is suitable for applications needing high-speed PWM generation and analog-to-digital conversion within a small footprint. Consider the available General Purpose I/O count and peripheral set against the system requirements before choosing over larger pin-count variants in the same family.

Microcontrollers Part Context

This device belongs to the dsPIC33CK64MC105 family, which combines MCU control attributes with DSP computational capabilities. The family supports functional safety standards including IEC 60730 Class B and ISO 26262 ASIL B. It offers various package options ranging from 28 to 48 pins, allowing flexibility in board space constraints while maintaining consistent core functionality across the series.

Microcontrollers Replacement Considerations

The dsPIC33CK64MC102-I/SS is a compatible alternative within the same family offering identical peripherals but with 64 Kbytes of Flash memory instead of 32 Kbytes. Designers must verify software compatibility and ensure the additional memory does not cause address mapping conflicts if migrating to this higher-capacity part.
