PIC24FV16KA301-I/SS - 16-Bit XLP MCU 16KB Flash 32MHz | Microchip
MPN: PIC24FV16KA301-I/SS ✓ פעילPIC24FV16KA301-I/SS סקירה
A microcontroller (MCU) is a single-chip computer integrating a CPU core, program memory, data memory, and peripherals on one die. The PIC24F family sits in the 16-bit microcontroller hierarchy above 8-bit PIC MCUs and below 32-bit ARM-based devices, targeting embedded control applications where power budget and peripheral integration matter more than raw processing throughput.
Key features include Microchip's XLP technology with Deep Sleep mode running dedicated DSBOR, DSWDT, and RTCC peripherals for industry-leading nanoamp-level standby power, an on-chip 12-bit ADC with up to 12 channels plus the Charge Time Measurement Unit (CTMU) for capacitive touch and precision measurement, and a wide 2.5V to 5V supply range that tolerates a 5V industrial bus directly.
Architecturally, the PIC24F core executes C-efficient 16-bit instructions from a modified Harvard bus with flash organized as 5.5K x 24-bit words. Code-Guard security partitions flash for bootloader protection, and the 17 I/O lines map rich peripherals including two UARTs, SPI, I2C, output compare, input capture, and a real-time clock calendar.
Typical applications include battery-powered sensor nodes, capacitive touch user interfaces, industrial sensor front-ends using the CTMU, and low-power data loggers where the RTCC must run for years on a coin cell.
For design, exploit the 2.5V-5.5V supply range to eliminate LDOs in 5V systems, and budget sleep currents against DSWDT period for battery-life estimates.

יישומים טיפוסיים
PIC24FV16KA301-I/SS מתאים עבור 6 יישוםs: Battery-Powered Sensor Nodes, Capacitive Touch User Interfaces, Industrial 5V Sensor Front-Ends, Real-Time Clock Data Loggers, Portable Medical and Wearable Monitoring, Home Appliance and White-Good Control.
Battery-Powered Sensor Nodes
The PIC24FV16KA301-I/SS is purpose-built for battery-powered sensing: XLP Deep Sleep mode keeps only the DSWDT and RTCC alive while the core is unpowered, allowing periodic wake-sample-transmit cycles that stretch battery life to years. The 2.5V minimum supply supports two-cell alkaline or coin-cell architectures without boost converters, and the 12-bit ADC digitizes sensor outputs directly. With 16KB flash, a complete sensor acquisition plus simple radio or UART protocol fits in code space. Place the MCU in Deep Sleep between samples and use the DSWDT interval to set duty cycle; the trade-off is slower wake latency versus continuous-run modes.
מומלץ
Capacitive Touch User Interfaces
With the integrated CTMU (Charge Time Measurement Unit), the PIC24FV16KA301-I/SS implements capacitive touch buttons and sliders without external touch controllers. The CTMU charges user pads with a constant current and measures charge time via the 12-bit ADC, detecting finger-induced capacitance changes at a fraction of the cost of dedicated touch ICs. The 17 GPIO provide up to a dozen independent touch keys plus LED or relay feedback lines. Microchip mTouch firmware libraries supply scanning, filtering, and calibration. Performance consideration: scan the CTMU in the main loop or timed interrupts and budget 1-2 mA average current during active scanning, returning to Deep Sleep between polls.
מומלץ
Industrial 5V Sensor Front-Ends
Many industrial systems still run 5V logic, and the PIC24FV16KA301-I/SS accepts a 5V rail directly, eliminating level shifters and LDOs that 3.3V-only MCUs would require. The 12-channel 12-bit ADC with internal reference digitizes 4-20 mA-derived, potentiometer, or ratiometric sensor signals, while the CTMU supports precise current and time measurements. UART, SPI, and I2C interfaces connect to displays, EEPROM, and field transceivers such as RS-485 adapters. Noise consideration: in electrically noisy panels, enable the ADC averaging and place 100 nF plus bulk decoupling at VDD; the wide 2.5-5V tolerance also rides out supply droop on long cable runs.
מומלץ
Real-Time Clock Data Loggers
The internal RTCC with 32.768 kHz crystal support continues counting time in Deep Sleep, making the PIC24FV16KA301-I/SS a self-contained time-stamped data logger. Combine the RTCC with the 512B EEPROM for calibration identifiers and the 16KB flash ring buffer for logged samples; the 12-bit ADC captures analog channels on scheduled wakeups. A supercapacitor or small lithium cell on VDD sustains the RTCC during main-battery replacement. Design consideration: crystal accuracy determines long-term timestamp error, so choose a 20 ppm crystal or apply the firmware temperature-compensation routines documented in Microchip's RTCC application notes.
מומלץ
Portable Medical and Wearable Monitoring
For portable diagnostic patches and wearable monitors, the PIC24FV16KA301-I/SS offers the combination of nanoamp-class Deep Sleep, on-chip RTCC for event timing, and a 12-bit ADC for physiological front-ends such as pulse or temperature channels. The 20-SSOP small footprint and surface-mount body suit compact enclosures, and the 5V-tolerant I/O simplifies charging-circuit interfacing. Firmware can use the DSWDT as a failsafe that resets a hung application without waking the RTCC. Compliance note: final products must complete IEC 60601 system certification independently; the MCU's low sleep current directly translates to smaller batteries and longer patient-use intervals between charges.
מומלץ
Home Appliance and White-Good Control
Appliance control boards benefit from the PIC24FV16KA301-I/SS's 5V direct supply, robust industrial temperature range of -40C to +85C, and capacitive touch capability replacing mechanical switches that wear out. Timer2/Timer3 plus output-compare peripherals generate PWM for fan, blower, or heater control, while the 12-bit ADC reads NTC thermistors and user potentiometers. The Code-Guard flash partitioning protects a bootloader from field firmware corruption. Design tip: drive triacs or relays through GPIO with adequate opto-isolation, and use the CTMU touch keys behind a grounded shield plane to reject mains-borne interference from adjacent motor drives.

הערות תכנון
The VCAP pin (pin 19) connects the PIC24F internal 2.5V core regulator to an external stabilizing capacitor; Microchip specifies a low-ESR 10 uF tantalum or ceramic capacitor to VSS on this pin. Omitting it or using an undersized/high-ESR part causes brown-outs and erratic execution. This capacitor must be placed within a few millimeters of pin 19 with a short, wide ground return. Do not drive or load the VCAP pin externally, and never use it as a low-voltage supply output for other circuitry.
Estimated: the 20-SSOP package dissipates only a few tens of milliwatts in typical operation (3-5 V x 10-20 mA active current, roughly 15-100 mW), so no heatsinking is needed. Thermal management attention should instead target Deep Sleep current: every microamp through pull-ups, divider chains, or the RTCC crystal circuit multiplies across months of battery life. Disable unused peripheral clocks via PMD registers and configure unused I/O as outputs driving low or inputs with internal pull-downs to eliminate floating-input shoot-through current.
For ICSP programming and debugging, route MCLR (pin 1), PGD (RB0/pin 11), and PGC (RB1/pin 12) to a standard 5-pin Microchip programming header. Keep RB0/RB1 free of strong pull-downs or load switches during programming. Decouple VDD (pin 7) with 100 nF ceramic plus 1-10 uF bulk, placed close to the pin. If using the secondary oscillator for the RTCC, keep the 32.768 kHz crystal traces short and guard them with ground pour, because the low-amplitude swing is highly susceptible to capacitive coupling from fast digital lines.
Three frequent migration errors: (1) the non-V PIC24F16KA301 cannot replace this part in 5V sockets - check the V in the ordering code; (2) K-series (KM) drop-ins have no EEPROM, so code storing calibration data in EEPROM must move to flash emulation; (3) ADC results differ between the KA and KM ADC implementations - re-verify scaling constants when porting firmware. Also note the I suffix temperature limit is +85C; designs exceeding that must use extended-temperature variants such as PIC24FV08KM202-E/SS.
