PIC24FV32KA304-E/PT 概述
A PIC® microcontroller is a self-contained 16-bit computing system on a single CMOS die, integrating CPU core, Flash program memory, SRAM data memory, EEPROM, multiple timers, ADC, communication peripherals, and flexible I/O. Within the broader taxonomy, this device belongs to the 16-bit PIC24F family -> Microchip PIC® MCU family -> Microcontrollers (MCU) -> Embedded Processors & Controllers -> Semiconductor ICs. It is designed for general-purpose embedded use, with the FV (wide-voltage) variant supporting both 3.3V and 5V system rails from a single part.
Key features include 32 MIPS CPU throughput, 32KB self-programmable Flash, 2KB SRAM, 512B EEPROM, hardware RTCC with calendar mode, two I²C/SPI, two comparators, and 5 CCP/PMP/EPMP modules. The CTMU enables capacitive touch sensing, while the 12-bit A/D converter provides up to 500 ksps conversion. eXtreme Low Power (XLP) technology adds Deep Sleep mode with current down to tens of nA, plus DSBOR and DSWDT for robust battery operation across the -40°C to +125°C (E = Extended) temperature range.
Architecturally, the PIC24FV32KA304 uses a 16-bit modified Harvard CPU with a hardware multiplier, 17 x 17-bit working registers, and a 24-bit instruction word — delivering 1.5x the throughput of 8-bit PIC16 MCUs at the same clock. The 5V-tolerant I/O and wide 2.0V-5.5V supply make it ideal for mixed-voltage designs, while dedicated peripherals like the RTCC calendar with Deep Sleep and CTMU simplify battery-aware designs.
Typical applications include battery-powered IoT sensor nodes, portable medical monitors, smart thermostats, capacitive touch user interfaces, e-metering data loggers, and ultra-low-power remote controls. The 32KB Flash, 12-bit ADC and CTMU combination is a frequent choice for capacitive-touch human-machine interfaces.
When designing with this part, ensure the 5V-tolerant pins observe the absolute maximum ratings and that decoupling is placed within 5 mm of each VDD pin. The 44-TQFP package enables easy hand-soldering and rework, and the same footprint is shared across the entire PIC24F(V)32KA304 family, allowing PCB reuse across Flash/RAM variants and temperature grades.

典型应用
PIC24FV32KA304-E/PT 适用于 6 应用s: Battery-Powered IoT Sensor Node, Capacitive-Touch Human-Machine Interface, Portable Medical Monitor, Smart Thermostat / HVAC Controller, Electronic Meter / Data Logger, Ultra-Low-Power Remote Control / Wireless Node.
Battery-Powered IoT Sensor Node
The PIC24FV32KA304-E/PT is purpose-built for battery-powered IoT sensor nodes. Its nanoWatt XLP Deep Sleep mode holds current in the tens of nA with full RAM retention, while the hardware RTCC with calendar wakes the device periodically without CPU involvement — extending coin-cell and Li-ion battery life to multi-year horizons. The integrated 12-bit ADC and CTMU enable temperature, light, or capacitive-touch sensing in a single chip. The 2.0V to 5.5V supply range covers both 3.3V coin cells and USB/5V sources without level shifting. The 44-TQFP package exposes 38 I/O for sensor I/O expansion, while 32 KB of Flash holds application code plus an over-the-air (OTA) bootloader for remote firmware updates.
推荐
Capacitive-Touch Human-Machine Interface
The PIC24FV32KA304-E/PT pairs its 12-bit ADC with the on-chip CTMU (Charge Time Measurement Unit) to scan up to 38 capacitive-touch electrodes without an external touch controller. Touch processing runs entirely on the 32 MIPS CPU, eliminating extra BOM and firmware complexity. The XLP feature set keeps the touch-scanning standby current in the low-µA range, suitable for mains-powered or battery-powered appliances. The wide 2.0V to 5.5V supply removes the need for a separate 3.3V rail when used on 5V white goods. With 32 KB of Flash and 2 KB of RAM, the device holds touch libraries plus UI animation code on-chip.
推荐
Portable Medical Monitor
In portable medical monitors such as blood-pressure cuffs, pulse oximeters, and glucose meters, the PIC24FV32KA304-E/PT combines the precision of a 12-bit 500 ksps ADC with XLP extreme low power to deliver accurate biosignal measurements on small batteries. The 5V-tolerant I/O accepts analog signals from standard sensor front-ends, while the 38 I/O drive TFT/LCD panels directly for on-device display. Deep Sleep mode with RTCC calendar keeps the device ready for periodic measurement reminders without draining the battery. The Extended -40°C to +125°C operating range supports storage and use from refrigerator to bedside. Hardware math support from the 16-bit core accelerates DSP-style filtering of biometric signals in firmware.
推荐
Smart Thermostat / HVAC Controller
The PIC24FV32KA304-E/PT is well-suited for smart thermostats and HVAC controllers where mixed-voltage I/O, capacitive touch, and long battery life converge. The 5V-tolerant pins interface directly to triac-driving opto-isolators for 24 VAC furnace control, while the wide 2.0V to 5.5V supply accepts the 3.3V rail from a Wi-Fi/BLE module. The RTCC tracks time-of-day scheduling even in Deep Sleep. The CTMU enables sleek glass-front-panel touch interfaces with no mechanical buttons, and the 38 I/O leave plenty of headroom for relays, TRIACs, and sensor fan-out. The Extended temperature grade operates reliably in unconditioned equipment closets.
推荐
Electronic Meter / Data Logger
The PIC24FV32KA304-E/PT excels in e-metering and data-logging designs that need precise analog sampling, real-time clocking, and long battery life. The hardware RTCC with calendar stamps logs with absolute time even in Deep Sleep, while 32 KB of Flash stores months of measurements with the EEPROM available for non-volatile parameter storage. The 12-bit ADC with 500 ksps captures current/voltage transients for power-quality metering. The 38 I/O interface to displays, isolated comm ports, and tamper-detection switches. Wide-voltage operation tolerates battery droop and AC-derived rails alike.
推荐
Ultra-Low-Power Remote Control / Wireless Node
For RF remotes, BLE beacons, and LoRaWAN endpoints, the PIC24FV32KA304-E/PT provides the lowest standby current and a wake-on-event architecture that pairs cleanly with sub-1GHz or BLE modules. Deep Sleep with RTCC calendar and external interrupt wake lets a coin cell last for years while still keeping accurate time-stamping. The 32 KB Flash holds simple RF stacks and remappable MAC addresses. The wide supply range lets the same design run from 3V coin cells, 3.3V LDO rails, or 5V USB power, while the CTMU handles touch or push-button wake.

设计说明
Place a 100 nF ceramic decoupling capacitor within 5 mm of every VDD pin, with a 10 µF bulk capacitor near the largest VDD/VSS pair. The PIC24FV32KA304-E/PT draws significant current spikes on internal regulator switching during Flash programming; insufficient decoupling will cause programming failures and erratic resets. For Deep Sleep mode below 1 µA, isolate analog and digital VDD planes and use a low-IQ LDO (e.g. MCP1700) for the always-on rail.
Route the MCLR pin through a 10 kΩ pull-up to VDD and place the ICSP programming header (PGC/PGD on RB6/RB7) so that production firmware programming and debug can be done without removing the chip. The 44-TQFP footprint allows a 4-layer PCB with full power plane; keep switching signals (SPI, I²C) short and avoid routing them under the MCU to minimize noise injection into the analog pins.
Do not assume the PIC24FV32KA304-E/PT is a drop-in for PIC24F-only designs at 3.3 V — both work, but the 'FV' is what you want if your design can ever run on 2 V (e.g., from a nearly-depleted coin cell). Conversely, swapping the PIC24FV32KA304 for the F-only PIC24F32KA304 in a 5V design is fine. Watch out for VDD minimum at full MIPS — at 32 MHz, full-speed operation may require at least 3.0 V VDD per the datasheet, so verify your 3.3 V rail has enough margin.
For capacitive-touch designs using the CTMU, the touch electrode traces must be guarded by a driven shield ring and not run parallel to high-frequency signals. Use the Microchip AN1250 and TB3065 application notes for tuned electrode geometries. The internal ADC reference stability depends on a clean VDD; for absolute ADC accuracy, add a 10 µF + 100 nF filter at the AVdd pin.
