PIC24FV16KA304-I/PT Overview
A 16-bit microcontroller (MCU) is a microprocessor that uses a 16-bit data path, a 16-bit ALU, and 16-bit-wide registers, sitting in the hierarchy between 8-bit MCUs (PIC16, AVR, 8051) and 32-bit MCUs (Cortex-M, PIC32). PIC24F parts belong to Microchip's 16-bit DSC/MCU family and target low-power embedded designs that need more performance and richer peripherals than 8-bit PIC MCUs but want lower cost than PIC32. Within the PIC24F umbrella, the KA3 sub-family emphasizes eXtreme Low Power (XLP) consumption in the microamp range with multiple Deep Sleep modes.
Key features include a 16 MIPS CPU from a 32 MHz oscillator, 16 KB Flash (5.5K x 24 instruction words), 2 KB SRAM, 512 B EEPROM, 12-bit ADC, CTMU for capacitive touch or current measurement, RTCC with alarm, and up to 39 I/O pins on the 44-pin TQFP package. The wide Vin range and XLP modes give nanoWatt sleep currents that match competing low-power MCUs while preserving an easy migration path within the PIC24F family.
Typical applications include handheld battery-powered instruments, sensor hub nodes with capacitive touch, always-on metering, low-power wireless sensor nodes (when paired with a radio like MRF24WG0MA), and industrial 24V-sensor interface boards. Each use case benefits from the part's nanoWatt XLP sleep, RTCC retention, and the CTMU for direct sensor front-ends.
When designing with this part, observe Microchip's Deep Sleep best-practice notes in the datasheet: configure DSBOR/DSWDT for your safety budget, retain RTCC for scheduled wakeups, and use CTMU calibration for accurate capacitive readings. Run-time selection of low-power modes must be paired with careful peripheral gating to fully realize the nanoWatt XLP benefit.

Typical Applications
PIC24FV16KA304-I/PT is suitable for 6 applications: Battery-Powered Sensor Hub with Always-On RTCC, Capacitive Touch User Interface, Industrial 24V Sensor Interface, Portable Medical / Health Monitoring, Low-Power Wireless Sensor Node, Metering and Energy Monitoring.
Battery-Powered Sensor Hub with Always-On RTCC
The PIC24FV16KA304-I/PT's nanoWatt XLP Deep Sleep mode and RTCC retention enable sensor-hub nodes that sleep in the microamp range and wake on a scheduled basis. The retained RTCC keeps wall-clock time during Deep Sleep while DSBOR/DSWDT protect the device from brown-out and watchdog events, and the CTMU allows direct capacitive or current sensing without an external front-end. Combined with 16 KB Flash / 2 KB SRAM / 512 B EEPROM, this device suits multi-year battery-life sensor platforms.
Recommended
Capacitive Touch User Interface
The PIC24FV16KA304-I/PT's integrated CTMU plus 12-bit ADC delivers button, slider, and proximity-sensing front-ends without a dedicated touch controller. With 16 MIPS and 16 KB Flash, it can also host a small UI state machine and serial back-channel (UART/I2C). Per the Microchip CTMU application note, the CTMU calibration routine must be copied into RAM for production-grade accuracy. This makes the part ideal for white-goods, appliance, and industrial HMI panels.
Recommended
Industrial 24V Sensor Interface
Industrial sensor interfaces typically run from 24V industrial buses that must be regulated down to MCU-friendly levels. The PIC24FV16KA304-I/PT's wide 2.0 V to 5.5 V Vin allows direct supply from a regulated 5V rail and its 5V-tolerant I/O simplifies level shifting to 5V industrial transceivers. Its -40C to +85C industrial temperature range and 16 MIPS performance accommodate standard 4-20 mA loop and binary-sensor industrial protocols.
Recommended
Portable Medical / Health Monitoring
The PIC24FV16KA304-I/PT's nanoWatt XLP consumption, RTCC retention, and CTMU are well-matched to portable, body-worn devices where multi-year battery life and continuous timekeeping are mandatory. The 12-bit ADC supports precision measurement of bio-z or temperature front-ends, and the 5V-tolerant I/O permits simple 3.3V or coin-cell operation. Per the family datasheet, the part is designed to deliver nanoamp Deep Sleep currents suitable for medical-device duty cycles.
Recommended
Low-Power Wireless Sensor Node
Paired with a sub-GHz or 2.4 GHz radio, the PIC24FV16KA304-I/PT forms a wireless sensor node that spends most of its life in Deep Sleep and wakes briefly to measure, transmit, and return to sleep. The RTCC schedules wakeups; the CTMU handles sensor readout; the UART/SPI interfaces drive the radio. With 16 KB Flash and 2 KB RAM the part comfortably fits a small MAC layer plus sensor stack while running from a CR2032 cell.
Recommended
Metering and Energy Monitoring
The PIC24FV16KA304-I/PT is well-suited for energy metering and data-logging endpoints thanks to its 12-bit ADC, CTMU current measurement, RTCC retained in Deep Sleep, and wide Vin for direct 5V or 3.3V supply. The 512 B EEPROM supports calibration constants and rolling-energy-log storage, while the nanoWatt sleep current keeps idle power budget near zero. This makes it a strong fit for gas, water, and electricity metering peripherals.

Key Differentiators
- Wide 2.0V-5.5V Vin with nanoWatt XLP Deep Sleep (vs PIC24F16KA304-I/PT)
- Drop-in upgrade to 32 KB Flash in same 44-pin TQFP (vs PIC24FV32KA304-I/PT)
- CTMU + 12-bit ADC integrated (vs PIC24FJ48GA004-I/PT)

Design Notes
Use the PIC24FV16KA304-I/PT's Deep Sleep mode (DS) for nanoWatt-class sleep current (under 1 uA with RTCC retained). Per the Microchip XLP family datasheet, configure DSBOR and DSWDT as the safety nets - DS deep-sleep may not wake on every interrupt source. Estimated: assuming a CR2032 cell at 220 mAh and 2 uA average idle, total runtime reaches ~12 years before depletion near 2.0V cutoff.
Do not assume the standard-voltage PIC24F16KA304-I/PT and the wide-voltage PIC24FV16KA304-I/PT are interchangeable. The 'F' (1.8V-3.6V) variant has no 5V tolerance and no 5V regulator; exposing it to a 5V rail will damage the part. Use the 'FV' (2.0V-5.5V) variant for 5V-tolerant industrial designs. Source: Microchip PIC24F KA3 family datasheet section on voltage regulators.
Place VDD bypass capacitors (typically 10 uF bulk + 100 nF ceramic) within 5 mm of the VDD pins (11 and 28) and VSS pins (8, 27, 39) on the 44-pin TQFP. For ADC use, add a small ferrite or pi-filter on analog VDD to keep the 12-bit ADC below 1 LSB noise. Per the PIC24F KA3 PCB guidelines, the exposed pad (if present on TQFP variant) should be tied to VSS for thermal dissipation.
Route the 32 MHz primary oscillator and the 32.768 kHz secondary oscillator (SOSC) traces as short, ground-screened pairs to avoid coupling noise into the RTCC or ADC. The CTMU current source is sensitive to ground bounce, so isolate its analog ground from noisy digital returns. Per the Microchip CTMU application note, dedicate a clean analog ground island for CTMU-measured nodes.
Compliance Information
