What is a PIC24 16-bit MCU? The PIC24 family is Microchip's general-purpose 16-bit Flash microcontroller line based on a modified Harvard RISC architecture. Within the PIC portfolio it sits between the 8-bit PIC16/PIC18 and the 32-bit PIC32MX, offering 16 MIPS performance, 16-bit-wide data paths, and DSP-friendly instructions while retaining the deterministic interrupt model of the PIC ecosystem. XLP technology adds dedicated Deep Sleep peripherals such as DSBOR (Deep Sleep Brown-Out Reset), DSWDT (Deep Sleep Watchdog Timer) and RTCC (Real-Time Clock/Calendar) that keep operating current below a few microamps while retaining timekeeping and reset supervision.
On-chip peripherals include a 12-bit ADC with up to 16 channels, a Charge Time Measurement Unit (CTMU) for capacitive touch and current measurement, multiple 16-bit timers, a 5V-tolerant I/O structure, and standard serial interfaces (UART, SPI, I2C). The CTMU is particularly valuable for low-cost touch buttons and slider decoding without an external analog front end.
Architecture: a 16-bit wide datapath with a hardware multiplier, single-cycle 16x16 MAC support, and an interrupt controller with a programmable priority scheme. The MCU is supported by MPLAB X IDE, the XC16 compiler, and the MPLAB Code Configurator (MCC) for rapid peripheral setup.
Typical applications include battery-powered sensor nodes, wearable health and fitness devices, low-power wireless remotes, IoT edge nodes with sleep duty cycling, industrial metering, and any design that needs 16-bit performance with sub-microamp Deep Sleep standby. The wide 2.0 V-5.5 V VDD range allows direct operation from single-cell Li-ion, two AA cells, or USB 5 V rails.
Design tip: take advantage of the Deep Sleep peripherals (DSBOR, DSWDT, RTCC) to wake the CPU only when an event occurs, holding the core in a sub-microamp state for the majority of the duty cycle. Use the CTMU for capacitive touch instead of an external controller to reduce BOM cost and PCB area.

Ứng dụng tiêu biểu
PIC24FV16KA304T-I/PT phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Nodes, Wearable Health and Fitness Devices, Industrial Metering and Data Loggers, Capacitive Touch Human-Machine Interfaces, Low-Power Wireless Remote Controls, Energy-Efficient Building Automation.
Battery-Powered IoT Sensor Nodes
The PIC24FV16KA304T-I/PT's wide 2.0-5.5 V VDD range lets it run directly from a single 3.6 V primary Li-SOCl2 cell or a 3.0 V CR2032 coin cell without a boost converter. Its XLP Deep Sleep mode keeps the part below a microamp when idle, while RTCC, DSBOR and DSWDT run in Deep Sleep to maintain timekeeping and supervision. The 12-bit ADC plus CTMU handle temperature, humidity and gas-sensor analog front ends, and the 16 MIPS core runs small TCP/IP or LoRaWAN stacks. This combination of wide voltage, sub-microamp standby and integrated analog reduces the BOM of a wireless sensor node by one or two external ICs.

Wearable Health and Fitness Devices
Wearables demand microamp standby and small PCB area, both of which the PIC24FV16KA304T-I/PT delivers. The on-chip CTMU enables capacitive touch buttons (start/stop, mode) without an external touch controller, reducing BOM and PCB real estate in a TQFP-44 package. The 12-bit ADC samples photoplethysmography (PPG) and temperature sensor signals directly, while the XLP core enters Deep Sleep between heart-rate samples, draining negligible current. The 2.0-5.5 V supply range covers rechargeable Li-ion, coin cells and USB charging paths in the same wearable hardware.

Industrial Metering and Data Loggers
Industrial metering applications benefit from the PIC24FV16KA304T-I/PT's 32 MHz / 16 MIPS core, which handles sensor linearization, calibration math, and local storage to the 512 B EEPROM between transmit intervals. The 12-bit ADC with up to 16 channels reads multiple sensors (flow, pressure, temperature) on the same die, while the 5 V-tolerant I/O interfaces directly to legacy industrial signal levels. The -40C to +85C industrial temperature range is rated for outdoor metering cabinets. The wide 2.0-5.5 V supply lets the same PCB operate from 3.6 V battery or 5 V mains-fed rails.

Capacitive Touch Human-Machine Interfaces
The PIC24FV16KA304T-I/PT's CTMU (Charge Time Measurement Unit) enables direct capacitive touch sensing on any GPIO pin, supporting buttons, sliders and proximity sensors without an external touch controller. Combined with the Microchip mTouch library in MPLAB Code Configurator, engineers can build a complete touch HMI with glass overlay and backlighting on the same TQFP-44 footprint. The XLP architecture keeps idle current below a microamp, ideal for always-on control panels. The 2.0-5.5 V VDD range supports USB-powered and battery-powered touch panels.

Low-Power Wireless Remote Controls
Wireless remotes spend most of their life in sleep and wake only on a button press or RF receive interrupt, exactly the use case the PIC24FV16KA304T-I/PT's XLP Deep Sleep mode targets. The CTMU scans capacitive or mechanical buttons at microamp current, and the 32 MHz core bursts to full speed only to encode and transmit the packet. Operating from 2.0-5.5 V, the same hardware runs from a CR2032 coin cell or a 2x AA battery pack. The 16 MIPS headroom is more than enough for sub-GHz proprietary stacks or BLE HCI.
Được đề xuất
Energy-Efficient Building Automation
Building automation nodes such as occupancy sensors, thermostats and HVAC controllers benefit from the PIC24FV16KA304T-I/PT's combination of 16 MIPS processing, 12-bit ADC and sub-microamp Deep Sleep. The wide 2.0-5.5 V supply rails accept 24 V AC-derived DC or battery backup without level shifters. UART, SPI and I2C peripherals interface directly to environmental sensors, LCD displays and wireless modules. The 44-pin TQFP provides enough I/O for keypad input, relay outputs, status LEDs and a real-time clock backup.

Bảo phân biệt quan trọng
- Wide 2.0-5.5 V VDD operation in the XLP 16-bit family (vsPIC24FJ16KA304-I/PT)
- Sub-microamp XLP Deep Sleep with active RTCC, DSBOR, DSWDT (vsPIC24FJ64GA002-I/PT)

Ghi chú thiết kế
Take advantage of XLP Deep Sleep whenever possible: configure DSBOR, DSWDT and RTCC to run in Deep Sleep so the core can stay below a microamp between events. Estimated: at 3.3 V and 25 C, Deep Sleep current for the KA family is in the tens of nanoamps with RTCC active, vs hundreds of microamps in normal Sleep, so a 1% wake duty cycle can cut average current to roughly 1-2 uA in a typical sensor node. This is the single largest power savings on the platform.
Do not confuse the PIC24FV16KA304 ("FV" wide-voltage, 2.0-5.5 V) with the PIC24FJ16KA304 ("FJ", 2.0-3.6 V only). They share the same TQFP-44 footprint and Flash map, but the FJ silicon will be damaged if VDD rises above 3.6 V. Check the second letter of the prefix when sourcing second-source: V = wide voltage, J = 3.3 V only. According to the Microchip PIC24FV32KA304 family datasheet, the absolute-maximum VDD is 6.5 V for FV parts and 4.0 V for FJ parts.
The TQFP-44 (PT) package has a typical theta_JA of approximately 50-60 C/W on a 2-layer JEDEC test board, so at the maximum 32 MHz clock and 100% CPU utilization, the silicon dissipates well under 100 mW and self-heating is not a concern. Even at the 5.5 V upper VDD rail, total chip power in active mode stays under ~30 mW, leaving substantial thermal margin for industrial -40C to +85C operation. No external heatsink is required for any documented application.
