- 16-bit PIC24 core delivers 16 MIPS at 32 MHz for efficient real-time control at low power
- 12-bit ADC with CTMU supports capacitive touch sensing and precision analog measurement in a single device
- Compact 44-pin QFN package minimizes board area for space-constrained handheld and wearable designs
Applications
The PIC24F32KA304-I/ML is targeted at low-power embedded control applications such as home appliance panels, capacitive touch interfaces, and portable measurement instruments that benefit from on-chip EEPROM for calibration data storage. Its 16-bit PIC24 architecture and 16 MIPS throughput at 32 MHz provide ample processing headroom for sensor fusion and simple communication stacks in IoT edge nodes. The integrated CTMU peripheral further enables direct capacitive touch sensing without dedicated touch controller ICs, reducing overall BOM count.

Frequently Asked Questions
How much non-volatile storage does the PIC24F32KA304-I/ML provide without external Flash?
The PIC24F32KA304-I/ML integrates 32 KB of Flash program memory and 512 bytes of on-chip EEPROM data memory, allowing firmware and calibration constants to be stored and updated independently without requiring external SPI or I2C Flash devices, which simplifies PCB design and lowers system cost.
Can the PIC24F32KA304-I/ML support capacitive touch interfaces natively?
Yes, the built-in CTMU (Charge Time Measurement Unit) peripheral on the PIC24F32KA304-I/ML enables direct capacitive touch sensing, measuring charge time differences on up to several touch electrode inputs and eliminating the need for a separate touch controller IC, saving BOM cost in appliance control panels and consumer devices.
What clock frequency does the PIC24F32KA304-I/ML reach and how does it affect ADC sampling speed?
The PIC24F32KA304-I/ML runs at up to 32 MHz, delivering 16 MIPS, and its 12-bit successive-approximation ADC can achieve sample rates sufficient for audio-range and general sensor digitization tasks; the 16-bit architecture allows efficient post-processing of multiple ADC channels in industrial or medical measurement applications.
For a portable device requiring -40°C cold-start, does the PIC24F32KA304-I/ML qualify?
The PIC24F32KA304-I/ML in the I-grade temperature rating supports operation from -40°C to +85°C, confirming reliable cold-start in outdoor equipment, automotive accessories, and industrial handheld instruments that must function across wide ambient temperature extremes without de-rating performance.
