PIC24F16KA102T-I/SO 概述
What is a 16-bit microcontroller? A 16-bit MCU is a microcontroller with a 16-bit-wide data path, register file, and ALU, sitting between 8-bit MCUs (lower performance, lower cost) and 32-bit MCUs (higher performance, higher cost and power). Within Microchip's taxonomy the PIC24F family belongs to the broader PIC microcontroller family and to the dsPIC/DSC and MCU category, distinguished by nanoWatt XLP technology that enables deep-sleep currents below 1 uA, making PIC24F devices the typical choice for battery-powered and energy-harvesting applications.
Key features include up to 18 general-purpose I/O, 12-bit ADC with 9 analog channels, multiple 16-bit and 32-bit timers, a Real-Time Clock Calendar (RTCC) with dedicated 32 kHz domain, deep-sleep brown-out reset (DSBOR), deep-sleep watchdog timer (DSWDT), and ultra-low-power wake sources. The device supports 1.8V to 3.6V operation from a single supply, internal 8 MHz and 32 kHz oscillators, and a rich set of serial peripherals including UART, SPI, and I2C.
Architecturally the PIC24F16KA102 employs a modified Harvard RISC core with a 24-bit instruction word and 16-bit data path, paired with a wide peripheral set optimized for low duty-cycle applications. The XLP technology combines multiple low-power modes (Sleep, Deep Sleep, Retention) with peripheral event-based wake-up to keep average current consumption in the microamp range.
Typical applications include battery-powered IoT sensor nodes, wearable health monitors, remote control key fobs, smart meters, energy harvesting nodes, and industrial data loggers where multi-year battery life is required. The 28-SOIC footprint also supports hand-soldered prototypes and low-volume production.
When designing with this part, plan for the -40C to +85C industrial temperature range and ensure the supply decoupling network is placed within 5 mm of the VDDCORE and VDD pins. The 'T' suffix indicates tape-and-reel packaging for high-volume assembly.

典型应用
PIC24F16KA102T-I/SO 适用于 6 应用s: Battery-Powered IoT Sensor Nodes, Wearable Health Monitors, Remote Control Key Fobs, Smart Meter End Nodes, Energy Harvesting Sensor Nodes, Industrial Data Loggers.
Battery-Powered IoT Sensor Nodes
The PIC24F16KA102T-I/SO's nanoWatt XLP deep-sleep currents below 1 uA and 16 MIPS core make it ideal for battery-powered IoT sensor nodes that spend >99% of their time asleep. Its 1.8V-3.6V supply range accommodates single-cell alkaline, lithium coin-cell, and 2xAA chemistries directly, and the integrated 12-bit ADC reads battery voltage and sensor inputs without an external analog front-end. The dedicated RTCC with 32 kHz domain enables accurate timestamping while the MCU sleeps, and deep-sleep brown-out reset (DSBOR) plus deep-sleep watchdog (DSWDT) keep the node safe during brown-outs and firmware faults.
推荐
Wearable Health Monitors
Wearable health monitors - heart-rate patches, sleep trackers, fitness bands - depend on multi-month coin-cell battery life, which the PIC24F16KA102T-I/SO delivers through nanoWatt XLP sleep modes below 1 uA and event-based peripheral wake-up. The 12-bit ADC with 9 channels supports pulse-oximeter photodiode and biopotential electrode sampling, while 18 GPIO drive LEDs, haptic feedback and BLE module control lines. The 16 KB Flash fits complete BLE peripheral role stacks plus proprietary health algorithms.
推荐
Remote Control Key Fobs
Remote control key fobs require sub-microamp quiescent current to deliver multi-year battery life with a single CR2032 coin cell - the PIC24F16KA102T-I/SO's nanoWatt XLP technology targets exactly this regime. The 16 MIPS core handles rolling-code cryptographic algorithms in real time while the integrated 12-bit ADC reads the coin-cell voltage for low-battery warning. The 28-SOIC package keeps the BOM compact and the -40C to +85C rating covers automotive key-fob temperature extremes.
推荐
Smart Meter End Nodes
Smart-meter end nodes - water, gas, heat sub-meters - require years of battery life and reliable RTC timestamping for billing, both delivered by the PIC24F16KA102T-I/SO's RTCC with dedicated 32 kHz domain and deep-sleep DSBOR/DSWDT. The 12-bit ADC accurately reads pulse outputs from flow meters and temperature probes, while 18 GPIO drive LCD segments, optical tamper switches and wireless M-Bus/OMS modules. The 1.8V-3.6V supply range supports 3.6V lithium thionyl-chloride cells directly without a boost converter.
推荐
Energy Harvesting Sensor Nodes
Energy-harvesting sensor nodes - solar, thermal-gradient, vibration - operate from milliwatt-level harvested power with deeply intermittent duty cycles that demand nanoWatt XLP sleep currents. The PIC24F16KA102T-I/SO's sub-microamp deep-sleep and fast wake-up from the RTCC alarm or external event suit, allowing it to spend most of its life in retention and burst-process sensor data when the harvester can support it. The 1.8V minimum supply cold-starts from a depleted supercapacitor without external boost circuitry.
推荐
Industrial Data Loggers
Industrial data loggers - cold-chain temperature loggers, vibration monitors, machine-condition sensors - need months to years of unattended logging from battery or supercapacitor sources. The PIC24F16KA102T-I/SO's RTCC timestamps each sample with second precision while the XLP deep-sleep modes keep idle consumption below 1 uA between samples. The 16 KB Flash stores approximately 4000 12-bit ADC samples with local timestamps, and the 28-SOIC industrial-grade package supports 24/7 operation across -40C to +85C factory floors.

关键差异点

- Industrial temperature grade tape-and-capped variant （对比 PIC24F16KA102T-E/SSVAO (extended temp SSOP))

设计说明
Place the 10 uF bulk decoupling capacitor within 5 mm of the VDD pin and a 100 nF ceramic within 2 mm of the VDDCORE pin. For battery applications drawing < 100 uA average, route the decoupling network through the VDD pin only and disable unused peripherals via the PMDx register to achieve nanoWatt XLP deep-sleep currents below 1 uA. Estimated: with peripheral gating and 32 kHz RTCC active, deep-sleep current typically measures 50-300 nA on PIC24F16KA family silicon.
The 28-SOIC wide-body (7.50 mm) footprint is hand-soldering-friendly but requires thermal relief spoke patterns on the power and ground pads to prevent tombstoning during reflow. Keep the ICSP PGC/PGD traces short and away from switching converter edges; route the MCLR pull-up directly to VDD with a 10 kohm resistor and a 100 nF cap to ground for noise immunity. The exposed pad (if present on the package variant) must be soldered to a continuous copper pour for thermal performance.
Do not skip configuration-bit programming: the default PIC24F0 clock source is the internal FRC, and leaving the PLL bits in default state limits the device to 4 MIPS. Enable the watchdog timer (DSWDT) in production firmware - failure to do so lets a runaway software loop drain the battery. The ADC input pins double as digital I/O, so always configure the corresponding TRIS bit before reading an analog channel, and add 100 nF bypass caps directly across analog input sources for noise-sensitive measurements.
