PIC24F16KA102-I/SO - 16KB Flash XLP 16-bit MCU 28-SOIC | Microchip
MPN: PIC24F16KA102-I/SO ✓ Hoạt độngPIC24F16KA102-I/SO Tóm tắt
A 16-bit MCU (microcontroller unit) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), non-volatile EEPROM, and configurable peripherals (timers, ADC, communication interfaces). The PIC24F16KA family belongs to the broader category of mixed-signal microcontrollers -> microcontrollers -> integrated circuits -> semiconductors. The 16-bit modified-Harvard RISC architecture delivers deterministic interrupt latency and rich peripheral integration for embedded designs.
Key features include the nanoWatt XLP technology for industry-leading low-power operation with multiple deep-sleep modes (DSBOR, DSWDT, Deep Sleep), Real-Time Clock and Calendar (RTCC) with VBAT retention, an integrated 10-bit ADC with up to 9 channels, multiple Enhanced Capture/Compare/PWM (ECCP) modules, and configurable peripherals including UART, I2C, and SPI. The 28-SOIC package exposes 19 general-purpose I/O pins and supports In-Circuit Serial Programming (ICSP) and In-Circuit Debug (ICD) for development workflows.
Technically, the device operates from 1.8 V to 3.6 V across an industrial temperature range of -40 °C to +85 °C, with hardware multiplier, 16 x 16-bit working register array, and selectable internal/external oscillator topologies. The integrated brown-out reset (BOR), watchdog timer (WDT), and dual oscillator fail-safe clock monitor add reliability to safety-conscious applications.
Typical applications include battery-powered IoT sensor nodes, wearable health monitors, remote controls, energy-harvesting devices, low-power wireless sensor nodes, and industrial metering. The XLP features allow standby currents in the nanoampere range, enabling multi-year battery life on a single coin cell.
When designing with this MCU, use Microchip's MPLAB X IDE with the XC16 compiler for firmware development. Decouple VDD with at least a 100 nF ceramic capacitor placed close to the pins, and route the ICSP/PGD/PGC lines with short traces to programming header pads.

Ứng dụng tiêu biểu
PIC24F16KA102-I/SO phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Node, Wearable Health Monitor, Industrial Wireless Sensor Tag, Smart Remote Control, Energy-Harvesting Sensor Module, Battery-Backed Data Logger.
Battery-Powered IoT Sensor Node
The PIC24F16KA102-I/SO is an ideal host MCU for battery-powered IoT sensor nodes that wake intermittently to capture measurements and forward them via a low-power radio. Its nanoWatt XLP technology delivers deep-sleep currents around 20 nA with RTCC retention, enabling multi-year coin-cell operation. With 16 MIPS compute, 16 KB Flash, 2 KB RAM, and integrated I2C/SPI peripherals, the part interfaces directly with temperature, humidity, and motion sensors. Compared with 8-bit PIC MCUs, the 16-bit core accelerates on-node data aggregation and lightweight encryption. Place a 100 nF decoupling capacitor within 3 mm of VDD pins and route the ICSP/PGD/PGC traces away from switching rails to maintain noise-free programming.

Wearable Health Monitor
For wearable health monitors (heart-rate, SpO2, step-counter wristbands), the PIC24F16KA102-I/SO offers the small 28-SOIC footprint, XLP nanoWatt sleep currents, and sufficient RAM to buffer biosignals before BLE transmission. The 10-bit ADC and configurable PWM support LED driver control for SpO2 photoplethysmography, while the RTCC with VBAT retention keeps wall-clock time when the main battery is removed for charging. Operating from 1.8 V to 3.6 V aligns with single-cell Li-ion chemistries after regulation. Designers should optimize firmware for short active windows with longest possible deep-sleep intervals to maximize battery life between charges.

Industrial Wireless Sensor Tag
Industrial wireless sensor tags benefit from the PIC24F16KA102-I/SO's industrial -40 °C to +85 °C temperature range and robust on-chip peripherals. The 16-bit RISC core runs Modbus, IO-Link, or proprietary sensor protocols over UART, while the 10-bit ADC and ECCP modules handle analog signal conditioning and process control outputs. XLP nanoWatt technology allows multi-year operation on lithium-thionyl-chloride primary cells in remote tank-level or pipeline-monitoring installations. The 28-SOIC package is well suited to through-hole or hand-soldered industrial enclosures where QFN parts are difficult to rework.

Smart Remote Control
Smart remote controls for TVs, set-top boxes, and home automation hubs run on coin-cell or 2xAAA batteries and benefit from the PIC24F16KA102-I/SO's nanoWatt deep-sleep mode. The MCU wakes on key-press interrupt, transmits an IR or RF command, and returns to sleep within milliseconds, drawing average current in the single-digit microampere range. The 16 KB Flash accommodates IR protocol libraries (RC5, RC6, NEC, SIRC) and pairing/encryption logic. The 28-SOIC package is easy to hand-prototype, and the ICSP interface supports in-circuit firmware updates via a header.

Energy-Harvesting Sensor Module
Energy-harvesting sensor modules (solar, piezoelectric, thermoelectric) require extreme sleep currents to operate from micro-watt power budgets. The PIC24F16KA102-I/SO's nanoWatt XLP technology with deep-sleep currents in the tens of nanoamperes is a strong fit. The integrated RTCC with VBAT retention keeps wall-clock time even when the harvested supply collapses, enabling precise duty-cycling of measurement cycles. The 16-bit MCU computes energy-availability checks and synchronizes wake intervals with energy buffer state. Operating from 1.8 V to 3.6 V matches typical supercapacitor or Li-ion buffer voltages without additional regulation.

Battery-Backed Data Logger
Battery-backed data loggers (cold-chain monitors, HVAC recorders, asset trackers) leverage the PIC24F16KA102-I/SO's 16 KB Flash for firmware, 2 KB RAM for sample buffering, and 512-byte EEPROM for non-volatile event logs that survive power-loss events. The RTCC with VBAT retention provides accurate timestamps even when the primary battery is replaced, and the 10-bit ADC handles thermistor or voltage measurements. XLP nanoWatt technology permits multi-year logging on a primary cell, with periodic Bluetooth or NFC dumps for data retrieval. The 28-SOIC package simplifies hand-assembly for low-volume industrial SKUs.

Ghi chú thiết kế
Estimated: For a coin-cell battery-powered sensor node, the PIC24F16KA102-I/SO's deep-sleep current (~20 nA with RTCC) plus a 100 ms active wake every 60 s yields an average system current of roughly 1-5 microamperes, supporting multi-year operation on a 220 mAh CR2032. Ensure the LDO chosen for the 3.3 V rail has quiescent current under 1 microampere (e.g., MCP1700 at 1.6 microamperes) to avoid dominating the sleep budget. Disable unused peripherals and oscillator sources in firmware during sleep to minimize active current.
Place a 100 nF ceramic decoupling capacitor within 3 mm of each VDD/VDDCORE pin pair on the PIC24F16KA102-I/SO, and a bulk 10 microfarad capacitor near the ICSP header to suppress programming glitches. Route the ICSP/PGD and PGC traces as short, parallel, length-matched paths; avoid routing them near switching power or RF traces. Provide a 10 kohm pull-up on MCLR/RE3 (pin 28) unless the application actively drives the reset line; missing pull-ups are a common cause of intermittent programming failures.
Do not assume the internal 8 MHz oscillator is accurate enough for UART communications: enable the PLL with calibration against a 32.768 kHz crystal via the RTCC for accurate baud rates in industrial temperature ranges. When migrating firmware from a PIC24F16KA101-I/SO or PIC24F08KA102-I/SO variant, verify the Flash erase block size and program-memory model registers are updated; the smaller-memory variants have a different configuration map. Finally, leaving the JTAG pins unconfigured at startup may cause unwanted analog activity on those pins - explicitly set them to digital I/O in the initialization code.
