PIC24F04KA200T-I/ST 概要
A 16-bit microcontroller (MCU) is an embedded processor whose arithmetic logic unit operates on 16-bit data words in a single instruction, balancing code density and throughput for low-to-mid power applications. The PIC24F family sits in Microchip's hierarchy below 32-bit PIC32 and ARM Cortex-M MCUs but above 8-bit PIC16/PIC18, targeting ultra-low-power battery and energy-harvesting designs where processing headroom beyond 8 bits is required but system cost must stay minimal. The 'XLP' (eXtreme Low Power) designation indicates specialized low-power peripherals such as DSBOR, DSWDT, and RTCC retained in deep sleep.
Key features include 4 KB flash (1.375K x 24 instructions), 512 bytes SRAM, hardware multiplier, 3 x 16-bit timers, 2 x UART, 1 x SPI, 1 x I2C, 10-bit 500 ksps ADC with up to 9 channels, and 12 I/O pins with interrupt-on-change. The device supports -40C to +85C industrial temperature operation and offers 5 x 5 mm TSSOP-14 form factor compatible with hand-solderable prototypes.
The PIC24F04KA200 architecture combines a modified Harvard RISC core with DSP-like instructions, enabling efficient C compilation while retaining small code footprint. The nanoWatt XLP technology extends battery life through multiple sleep modes including deep sleep with RTCC retention at sub-microamp currents, making the family suitable for always-on IoT endpoints and remote sensor nodes.
Typical applications include IoT sensor nodes, battery-powered medical wearables, home automation peripherals, smart meters, remote controls, and consumer electronics requiring low-power 16-bit processing. The TSSOP-14 package is preferred when PCB area is constrained but moderate I/O count suffices.
When designing with this device, ensure the ICSP programming interface pins (PGEDx/PGECx) are accessible for in-circuit programming. The internal oscillator can drift over temperature; use the RTCC calibration for time-critical applications. Always derate the ADC input impedance per datasheet for accurate conversions above 200 ksps.

Battery-Powered IoT Sensor Nodes
The PIC24F04KA200T-I/ST fits battery-powered IoT sensor nodes through its nanoWatt XLP technology delivering sub-microamp deep sleep current with RTCC retention. The 4 KB flash supports small sensor-fusion firmware while 512 bytes RAM handles periodic measurement buffers. At 1.8V-3.6V operation the MCU accepts direct coin-cell or lithium battery input without regulators, and the 10-bit ADC at 500 ksps handles temperature, humidity, and analog sensor reads. Compared to 8-bit PIC16 alternatives, the 16-bit core (16 MIPS) processes sensor data faster, reducing wake time and total energy per measurement cycle - critical for multi-year battery life targets.

設計ノート
The PIC24F04KA200T-I/ST's nanoWatt XLP technology provides deep sleep currents below 1 uA with RTCC retention, but only when all peripherals are properly disabled before sleep entry. Sequence peripherals in this order: disable ADC, switch unused pins to digital outputs (not analog), disable unused peripherals via PMDx registers, then issue PWRSAV instruction. Without peripheral gating, deep sleep current can exceed 10 uA, dramatically shortening coin-cell battery life in sensor node applications.
Place a 0.1 uF decoupling capacitor as close as possible to the VDD pin (pin 8) with trace length under 5 mm. Add a bulk 10 uF capacitor on the same supply rail within 25 mm. The 14-TSSOP package's exposed thermal pad is not present on this part - ground is pin 5 (VSS). For ICSP programming access, route PGC (pin 11) and PGD (pin 12) to a programming header without series resistors greater than 100 ohm to ensure reliable in-circuit programming.
Do not leave unused I/O pins floating - configure as digital outputs tied low to minimize leakage current in sleep modes. The MCLR pin (pin 4) requires a 10 kohm pull-up to VDD if not used for external reset. The internal oscillator accuracy is typically +/- 2% over temperature; for UART communication use the RTCC calibration register or external crystal for reliable baud rates above 9600. Above 200 ksps ADC sampling, source impedance above 2.5 kohm introduces gain errors - use a low-impedance buffer or reduce sampling rate.
