Applications
The PIC24F16KA302-I/ML is a strong fit for portable consumer products, smart home touch panels, and low-power IoT nodes that require 16-bit processing at 32 MHz with integrated EEPROM for calibration data storage. The built-in CTMU module simplifies capacitive touch interface design for 1 to 16 touch buttons or sliders without external touch controllers. Its 28-pin VQFN package and 1.8 V to 3.6 V supply range suit coin-cell or single-cell Li-Ion battery-powered wearables and wireless sensor nodes.

Frequently Asked Questions
What makes the on-chip EEPROM of PIC24F16KA302-I/ML useful for calibration-heavy sensor designs?
The PIC24F16KA302-I/ML integrates 512 bytes of EEPROM that retains data through power cycles without external memory ICs. This is sufficient to store factory calibration coefficients for the 12-bit ADC, sensor offset values, and device configuration parameters, reducing BOM cost and I2C/SPI bus utilization in sensor nodes operating at 1.8 V to 3.6 V.
How does the CTMU module in PIC24F16KA302-I/ML simplify capacitive touch implementation?
The Charge Time Measurement Unit (CTMU) integrated in PIC24F16KA302-I/ML generates a precisely controlled current source used to charge a sense pad capacitance in under 1 µs, enabling up to 16 touch channels through the 12-bit ADC without external touch controller ICs. This reduces total system component count and PCB area compared to dedicated touch-controller solutions running from the same 1.8 V to 3.6 V supply.
For a 32 MHz embedded control design, when is PIC24F16KA302-I/ML a better choice than an 8-bit PIC18 MCU?
The 16-bit PIC24 architecture of PIC24F16KA302-I/ML provides 16 MIPS at 32 MHz with native 16-bit arithmetic and a larger address space compared to an 8-bit PIC18 at 20 MHz. This is advantageous when the application involves 16-bit sensor data processing, floating-point emulation, or more than 8 KB of program logic, while still keeping supply current below 5 mA active and entering sub-1 µA deep-sleep mode.
What supply voltage range does PIC24F16KA302-I/ML support and which battery chemistries are directly compatible?
PIC24F16KA302-I/ML operates from 1.8 V to 3.6 V, covering a discharged single-cell Li-Ion battery at 3.0 V down to 1.8 V, as well as 2 AA alkaline cells in series (nominal 3.0 V). This range also aligns with the 3.3 V logic levels common in Bluetooth and Wi-Fi SoC designs, allowing direct I/O interfacing without level shifters.
