Frequently Asked Questions
At what minimum supply voltage can PIC24F16KA102-I/SP operate and what clock speed does it support at that voltage?
PIC24F16KA102-I/SP operates down to 1.8 V minimum supply, running at up to 8 MHz at that voltage. Raising the supply to 2.0 V or higher enables the full 32 MHz clock speed and 16 MIPS throughput. This makes the device suitable for single-cell lithium (discharged to 2.0 V) or two-cell alkaline battery designs without an additional boost regulator.
How does the integrated CTMU module enable capacitive touch sensing without external ICs?
The Charge Time Measurement Unit (CTMU) generates a precision current source that charges an external sense electrode, and the 12-bit ADC measures the resulting voltage to detect touch events. With electrode capacitance typically in the range of 10 pF to 100 pF, the CTMU resolves capacitance changes of about 1 pF to 2 pF, allowing 4 to 16 touch buttons to be implemented using only copper pads on the PCB and no additional touch controller.
What memory resources does PIC24F16KA102-I/SP provide for data-logging applications?
The device includes 16KB Flash program memory and 2KB RAM. For logging beyond RAM, up to 512 bytes of the Flash can be used as non-volatile data storage, and an SPI or I2C external EEPROM can be added through the on-chip serial ports. The integrated RTCC maintains time with a 32.768 kHz watch crystal, stamping log entries without an external RTC chip.
How does PIC24F16KA102-I/SP compare to PIC24F08KA102 for designs needing more code space?
PIC24F16KA102-I/SP doubles the Flash from 8KB (PIC24F08KA102) to 16KB while keeping the same 28-pin SPDIP footprint, 1.8 V minimum supply, and peripheral set. When firmware exceeds 8KB — common once USB bootloaders, sensor drivers, and communication stacks are added — the 16KA102 is a pin-compatible, drop-in upgrade requiring no PCB changes, available with a typical 7-week factory lead time.
