PIC24FV16KA301-E/SS Descripción general
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and a rich set of peripherals onto one die. The PIC24F family sits within the broader 16-bit PIC architecture, which scales up to the dsPIC digital signal controllers. The XLP variants add Deep Sleep operating modes with sub-µA currents, targeting battery-powered and energy-harvesting applications where quiescent draw dominates battery life. The "FV" prefix in the part number denotes the wide-voltage silicon revision (2.5 V/3.3 V/5 V tolerant I/O and core).
Key features of the PIC24FV16KA301 include 16 MIPS performance per MHz, hardware multipliers, a 16-bit timer/counter bank, multiple UART/SPI/I2C serial interfaces, and the CTMU peripheral that allows calibrated µA-range current measurements for thermistors or capacitive buttons. The Deep Sleep mode retains RTCC, DSBOR (Deep Sleep Brown-Out Reset), DSWDT (Deep Sleep Watchdog Timer), and a small register file at currents typically under 1 µA, which is critical for applications that spend most of their life in standby.
Typical applications include portable medical sensors, smart thermostats, battery-powered IoT nodes, capacitive touch user interfaces, and remote controls. In each case, the combination of wide-voltage operation, RTCC retention, and CTMU-based sensing reduces external component count and extends battery service life.
When designing with this MCU, verify Vdd decoupling per Microchip's application note recommendations and confirm that the active supply current at the chosen MIPS rate fits within the power budget. For designs that require more code space, step up to the PIC24FV32KA301 within the same SSOP-20 footprint; for designs that need more pins, move to the 28- or 44-pin variants in the family.

Aplicaciones típicas
PIC24FV16KA301-E/SS es adecuado para 7 aplicacións: Battery-Powered IoT Sensor Node, Capacitive Touch User Interface, Smart Thermostat / HVAC Controller, Portable Medical / Wearable Device, Industrial Remote Control / HMI Keypad, Energy Metering / Sub-metering, Automotive Interior Lighting Controller.
Battery-Powered IoT Sensor Node
The PIC24FV16KA301-E/SS suits battery-powered IoT sensor nodes because its XLP Deep Sleep mode retains the RTCC, DSBOR, and DSWDT at sub-µA currents while keeping the 2 KB SRAM fully alive. In a typical coin-cell deployment, the MCU spends >99 % of its life in Deep Sleep and wakes on an RTCC alarm or external interrupt to read a sensor and transmit via a companion radio such as the MRF24XA or RN2483. The wide 2.5-5 V Vdd range lets the same board operate from a single CR2032, two AA cells, or a USB rail without level shifters. CTMU support also enables calibrated temperature or humidity measurements without a dedicated ADC front end.
Recomendado
Capacitive Touch User Interface
The CTMU peripheral in the PIC24FV16KA301-E/SS provides calibrated µA-range constant-current sources and timing measurement, enabling robust capacitive touch button or slider decoding without an external touch IC. Combined with the 12-bit ADC and the MCU's 16 MIPS throughput, a single PIC24FV16KA301 can scan 8-12 touch electrodes at a 50 Hz refresh rate while still leaving MIPS headroom for backlight PWM, buzzer control, and serial logging. The wide-voltage Vdd range is a useful advantage for appliances that must operate from 3.3 V logic or a 5 V backlight supply without additional regulators.
Recomendado
Smart Thermostat / HVAC Controller
The RTCC retained in Deep Sleep and the 12-bit ADC with up to 16 channels make the PIC24FV16KA301-E/SS a strong fit for wall-mount thermostats that must keep accurate wall-clock time across multi-year battery backup and read multiple thermistor inputs. The 16 KB Flash comfortably holds a PID control loop, an LCD segment driver, and a Modbus or BACnet stack for HVAC bus communication. The extended -40 °C to +125 °C temperature grade handles attic and outdoor mounting, and the wide-voltage silicon eliminates the need for separate 3.3 V and 5 V rails.
Recomendado
Portable Medical / Wearable Device
The combination of sub-µA Deep Sleep current, wide-voltage operation, and CTMU-based measurement channels supports wearable pulse-oximeter or activity-tracker implementations on a single Li-ion or coin-cell battery. The PIC24FV16KA301-E/SS can wake periodically to drive an optical sensor (LED + photodiode) via the CTMU's calibrated current source, capture the photodiode reading with the 12-bit ADC, and run simple signal-processing algorithms in 16 MIPS mode. The extended -40 °C to +125 °C rating is helpful for skin-contact wearables that may experience elevated temperatures during charging.
Recomendado
Industrial Remote Control / HMI Keypad
The PIC24FV16KA301-E/SS's 18 available I/O pins and multiple serial peripherals (UART, SPI, I2C) allow direct connection to a 4x4 keypad matrix, an LCD segment display, and a 2.4 GHz radio module such as the MRF24J40. The hardware multiplier and 16 MIPS throughput handle CRC generation and basic encryption for secure RF links without external coprocessors. The wide-voltage operation makes the same PCB usable in 3.3 V battery-powered and 5 V line-powered handheld enclosures.
Recomendado
Energy Metering / Sub-metering
The PIC24FV16KA301-E/SS's 12-bit ADC at up to 200 ksps, combined with the CTMU's calibrated current source, can sample shunt-resistor voltage and CT secondary current in single-phase energy-meter designs. The 16 KB Flash holds a metrology library, calibration tables in EEPROM (512 B), and a UART/SPI link to a host display or PLC. XLP Deep Sleep between measurement windows reduces average current to support long-life battery-backed meters.
Recomendado
Automotive Interior Lighting Controller
Although not AEC-Q100 qualified, the PIC24FV16KA301-E/SS's extended -40 °C to +125 °C temperature grade and wide-voltage Vdd allow it to be evaluated for non-safety automotive interior modules such as RGB ambient lighting controllers. The CTMU can drive MOSFET gates for PWM dimming, and the 16 MIPS throughput supports LIN or CAN software stacks. For production automotive designs, migrate to an AEC-Q100 qualified PIC24F variant.

Diferenciadores clave

- Wide-voltage silicon supports 2.5 V, 3.3 V, and 5 V Vdd on the same die (frente a PIC24F16KA301 (3.3 V only))
- CTMU peripheral for capacitive touch and calibrated µA-range measurements (frente a PIC24FV08KM202-I/SS (no CTMU))
Notas de diseño
Estimated: at 32 MHz / 16 MIPS and 3.3 V Vdd the active current is approximately 6 mA; at 1 MHz / 0.5 MIPS it drops to roughly 0.4 mA; in Deep Sleep with RTCC retained it is sub-µA. For battery-life calculations use the percentage of time spent in Deep Sleep vs active mode, weighted by the corresponding current from the datasheet's DC Characteristics table. Always place a 100 nF decoupling capacitor within 5 mm of the Vdd pin and a 10 µF bulk cap near the IC, per Microchip's analog design guidelines.
Route the analog AVdd/AVss pins separately from digital Vdd/Vss to minimize ADC noise coupling - even on a 20-pin SSOP that lacks dedicated AVss, isolate the analog reference pin with its own ground return and a ferrite bead if high-precision ADC measurements are required. Keep the MCLR pull-up resistor (typically 10 kΩ) close to the IC and add a 100 nF cap on MCLR if long reset-rise times are a concern in noisy environments.
Do not confuse the FV (wide-voltage) silicon with the F (3.3 V only) silicon - PIC24F16KA301 has a different Vdd range than PIC24FV16KA301. Also, the E (extended) vs I (industrial) temperature suffixes are pin-compatible and share firmware but only the I grade supports commercial/industrial environments; the E grade is mandatory only above +85 °C. Finally, ensure the CTMU calibration routine from the Microchip application note is executed at production test for accurate capacitive touch or temperature measurements.
