PIC24F16KA101-E/SS 概要
A 16-bit microcontroller (MCU) is a programmable processor that executes instructions on 16-bit data paths, offering higher code density and arithmetic precision than 8-bit parts while remaining simpler than 32-bit ARM Cortex-M devices. Within the broader taxonomy, this PIC24F belongs to the PIC24 MCU family, then to 16-bit microcontrollers, then to microcontrollers, then to embedded processors, and finally to integrated circuits. It is purpose-built for power-constrained and battery-powered designs where the XLP feature set (DSBOR, DSWDT, deep sleep, RTCC) extends battery life into the multi-year range.
Key specifications include a 32 MHz maximum operating frequency, 18 user I/O pins, a 10-bit ADC with multiple channels, and integrated peripherals such as comparators, UART/SPI/I2C, and a Real-Time Clock Calendar. The device operates from 1.8V to 3.6V and is qualified to the -E (extended) temperature grade. The 20-SSOP package provides a compact footprint well suited to space-constrained consumer and industrial modules.
Architecture-wise, the PIC24F core uses a 16-bit modified Harvard architecture with a wide 24-bit instruction word, enabling efficient C compilation through DecodeOne. XLP technology incorporates a deep sleep mode with sub-microamp current draw, an ultra-low-power watchdog timer, and a power-saving RTCC that can wake the part periodically - critical for energy-harvesting and primary-cell applications.
Typical applications include battery-powered sensor nodes, portable medical and wellness devices, remote controls, energy-harvesting wireless transmitters, low-power IoT end nodes, and industrial data loggers. The combination of wide operating voltage (1.8V-3.6V) and extended temperature range also suits automotive under-hood and outdoor installations.
When designing with this part, ensure decoupling capacitors are placed within 5 mm of the VDDCORE and VDD pins and that unused I/O are configured as outputs to minimize current draw. The XLP sleep mode requires the RTCC, DSWDT, or an external interrupt to be the wake-up source; relying on a busy-loop delay will defeat the nanoWatt current target.

主な用途
PIC24F16KA101-E/SS の用途: 6 件s: Battery-Powered Wireless Sensor Nodes, Portable Medical and Wellness Devices, Remote Controls and Consumer IR/RF Keys, Energy-Harvesting Wireless Transmitters, Industrial Data Loggers and HVAC Sensors, Low-Power IoT End Nodes.
Battery-Powered Wireless Sensor Nodes
The PIC24F16KA101-E/18-SS is ideal for battery-powered wireless sensor nodes because its XLP nanoWatt technology achieves sub-microamp deep-sleep current, dramatically extending battery life to 10+ years on a single CR2032 coin cell. The 16 KB Flash (5.5K x 24) accommodates typical sensor protocol stacks like Bluetooth Low Energy profiles or proprietary sub-GHz MAC layers, while 1.5 KB RAM supports buffering of recent samples. Its 1.8V-3.6V VDD range lets the MCU run directly from a single Li-ion, alkaline, or coin-cell battery without a regulator, reducing BOM cost. The 32 MHz / 16 MIPS core easily handles periodic sensor reads and radio transmits within tight duty cycles, and the integrated 10-bit ADC captures analog sensor data without an external converter.
おすすめ
Portable Medical and Wellness Devices
For portable medical and wellness devices such as pulse oximeters, glucose meters, and fitness bands, the PIC24F16KA101-E/18-SS delivers the low-power performance and analog integration required for battery-safety-critical products. The 10-bit ADC with multiple input channels directly digitizes sensor outputs from photodiodes, thermistors, or load-cell bridges, while the XLP deep-sleep mode keeps quiescent current below 1 uA so the device can sleep between measurements. The -40C to +125C extended temperature grade supports storage and transport across extreme conditions, important for outdoor and home-health devices. The 512-byte EEPROM safely stores patient calibration constants and usage logs through firmware updates, and the 18 I/O are sufficient to drive an OLED or segment LCD, read button inputs, and talk to a BLE module.
おすすめ
Remote Controls and Consumer IR/RF Keys
The PIC24F16KA101-E/18-SS suits remote-control and consumer IR/RF key fob designs because its deep-sleep current of less than 1 uA lets a coin cell last the typical 5-10 year shelf and use life of such products. The 16 KB Flash comfortably fits complex button-mapping and IR/RF protocol code (NEC, RC5, or proprietary), while the 32 MHz core delivers the precise timing required for carrier generation. Its 1.8V-3.6V supply range matches a single CR2032 (3V) directly without a boost regulator. The 18 I/O easily drive a 5x5 key matrix plus LED indicators, and the integrated UART/SPI/I2C interface allows pairing with low-cost RF transmitter companions for RF remote control products.
おすすめ
Energy-Harvesting Wireless Transmitters
The PIC24F16KA101-E/18-SS is well matched to energy-harvesting wireless transmitters (solar, thermal, vibration) because its XLP deep-sleep mode draws under 1 uA, allowing the MCU to operate from tiny harvested energy reservoirs that would otherwise be inadequate for conventional microcontrollers. The wide 1.8V-3.6V VDD range accepts the variable output of a harvester without complex regulation. The 32 MHz CPU can wake, take a sensor reading, transmit a packet, and return to sleep within tens of milliseconds - critical for minimizing energy per wake cycle. The RTCC and DSWDT provide autonomous wake sources without external components, and the 18 I/O are sufficient for interfacing energy-harvesting power management ASICs.
おすすめ
Industrial Data Loggers and HVAC Sensors
The PIC24F16KA101-E/18-SS is a strong fit for industrial data loggers, HVAC environmental sensors, and building-automation nodes where the -40C to +125C extended temperature grade is required. The 512-byte EEPROM provides reliable storage for calibration data and rolling event counters without external memory. Its 10-bit ADC digitizes 4-20 mA loop sensors, thermistors, and 0-10V HVAC analog signals with adequate resolution for trend applications. The XLP feature set ensures maintenance-free operation for years on battery or solar power, and the UART/SPI/I2C peripherals connect directly to RS-485 transceivers, LCDs, or wireless modules.
おすすめ
Low-Power IoT End Nodes
The PIC24F16KA101-E/18-SS powers low-power IoT end nodes such as smart-home sensors, occupancy detectors, and BLE beacons because its XLP nanoWatt technology and flexible wake sources enable multi-year battery life without external RTC chips. The 16 KB Flash holds BLE beacon profiles or simple MQTT-SN payloads, and the 32 MHz CPU encrypts and transmits data within sub-second wake windows. The 18 I/O support driving LEDs, reading push-buttons or PIR sensors, and communicating over SPI/I2C with sensor peripherals. Its compact 20-SSOP package fits inside small sensor enclosures, and the wide operating voltage range accepts a USB-charged Li-Po cell or two AA batteries directly.

設計ノート
Estimated: with VDD=3.3V and MCU drawing 20 mA active, decoupling the VDDCORE pin with a 100 nF X7R ceramic placed within 5 mm is mandatory for PIC24F XLP parts. Connect a bulk 10 uF tantalum or ceramic at the VDD pin to handle PLL inrush. Decoupling loop inductance of more than 10 nH can cause spurious brown-out resets in deep-sleep transitions - keep traces short and wide. The VDDCORE pin must NOT be driven externally; it is the output of the internal LDO and only accepts a decoupling cap.
Configure all unused I/O as outputs (not inputs) to prevent floating-input current draw that can erase the XLP nanoWatt sleep budget. Floating CMOS inputs on the PIC24F can source or sink tens of microamps per pin, which completely defeats deep-sleep power targets. Also, after programming via ICSP, remember that the PGEC1/PGED1 pins default to analog mode and must be reassigned to digital I/O in user code if used as general-purpose pins.
Place the 32.768 kHz crystal as close to the SOSCI/SOSCO pins (or the chosen low-power oscillator pins on the 20-SSOP) as possible and guard the traces against noisy digital lines like PWM or switcher SW nodes. Route the ICSP clock and data lines PGEC1/PGED1 with no series resistors (10 k pull-ups to VDD are recommended per Microchip programming spec). Avoid running high-frequency traces parallel to the crystal traces to minimize coupling into the RTCC.
For ADC measurements on noisy power rails, add an external RC filter (typically 1 kohm + 100 nF) at the analog input pin to band-limit switching noise below the ADC's Nyquist rate. The PIC24F16KA101 10-bit ADC samples at up to 500 ksps; if the source impedance is above 2.5 kohm, the internal sample-and-hold will not settle within the acquisition window. Use the dedicated VDDCORE/AVSS pair for ADC reference, not the noisy digital VDD rail.
