PIC24FJ128GA202-I/SP 概要
A microcontroller (MCU) is an integrated circuit that combines a CPU core, program and data memory, and a rich set of on-chip peripherals such as timers, communication interfaces, ADC/DAC modules, and GPIO into a single chip. The PIC24FJ family belongs to the modified Harvard RISC architecture family and uses 16-bit instruction words with up to 24-bit opcode extensions, balancing deterministic real-time performance with low active and sleep currents. PIC24F devices are positioned within Microchip's portfolio between 8-bit PIC16/PIC18 MCUs (cost-optimized, simpler) and dsPIC/PIC32 (32-bit, higher MIPS) — useful when code density, numeric range, and low energy are all required.
Key features of the PIC24FJ128GA202-I/SP include 128KB Flash, 8KB SRAM, an integrated crypto module for secure data handling, multiple serial interfaces (UART, SPI, I2C), 10-bit ADC, capture/compare/PWM modules, and deep-sleep current in the microamp range enabled by XLP technology. The integrated crypto engine accelerates AES-like operations without external companion ICs, reducing BOM and PCB area.
Architecturally, the device uses a 16-bit modified Harvard core with a 7-channel DMA controller, hardware multiplier, and multiple clock sources including a 32kHz low-power oscillator and an 8MHz internal RC. The crypto module provides a hardware-accelerated block for encryption/decryption, and the eXtreme Low Power design lowers run and idle currents compared with prior PIC24 generations.
Typical applications include secure IoT edge nodes, battery-powered sensor hubs, low-power wireless gateways, secure access control modules, smart metering, and industrial HMI panels. The combination of XLP current profiles and on-chip crypto is particularly attractive for devices that must sleep most of the time and encrypt rare bursts of telemetry.
When designing with this MCU, plan oscillator start-up timing and use the XLP deep-sleep retention mode wherever possible to extend battery life. Validate AES throughput against your protocol's session rate, and ensure the SPDIP-28 footprint provides sufficient thermal headroom at the target ambient.

主な用途
PIC24FJ128GA202-I/SP の用途: 6 件s: Secure IoT Edge Sensor Nodes, Battery-Powered Wearable Health Bands, Industrial HMI Control Panels, Smart Metering and Utility Endpoints, Secure Access Control Modules, Low-Power Wireless Gateways.
Secure IoT Edge Sensor Nodes
The PIC24FJ128GA202-I/SP fits secure IoT sensor nodes because its integrated crypto engine accelerates AES-like encryption for uplink telemetry without an external companion IC. Its 128 KB Flash holds a complete wireless MAC plus application firmware, while 8 KB SRAM supports buffering between sample bursts. XLP deep-sleep currents below 1 microamp extend coin-cell life for years of duty-cycled sensing. Engineers typically place the part on a 2-layer SPDIP carrier, route the 32 kHz crystal to the XLP oscillator pins, and use the 10-bit ADC to read temperature, humidity, or analog sensors directly.
おすすめ
Battery-Powered Wearable Health Bands
The PIC24FJ128GA202-I/SP suits battery-powered wearable bands thanks to XLP run and idle currents that keep average consumption under 50 microamps in a typical heart-rate sensing duty cycle. Its 32 MHz core executes signal processing for accelerometer and PPG data, while 8 KB SRAM is sufficient for short sample buffers. The integrated crypto engine secures Bluetooth pairing keys and over-the-air firmware updates. Designers commonly combine it with a low-cost BLE or sub-GHz radio and coin-cell, harvesting residual energy through the ADC reference path when the host is asleep.
おすすめ
Industrial HMI Control Panels
The PIC24FJ128GA202-I/SP drives small industrial HMI panels where its 16-bit core handles button scanning, LED PWM dimming, and serial protocol bridging without an external display controller. The 28-pin SPDIP package simplifies through-hole assembly for low-volume industrial SKUs that need long service life and easy field replacement. Its 2.0V to 3.6V supply tolerates 24V industrial rails when paired with a small switching regulator, and the 10-bit ADC reads potentiometers and analog sensors for closed-loop control with deterministic interrupt latency for safe panel response.
おすすめ
Smart Metering and Utility Endpoints
The PIC24FJ128GA202-I/SP is a strong fit for utility metering endpoints because its integrated crypto engine secures tariff and consumption data sent over narrowband PLC or wireless M-Bus links. The 128 KB Flash accommodates segmented metering firmware with rolling buffer support in 8 KB SRAM, while XLP sleep keeps the device below 30 microamps between transmissions. The SPDIP-28 package is field-replaceable and compatible with hand-soldered repair, which utility technicians prefer in deployed meter installations.
おすすめ
Secure Access Control Modules
The PIC24FJ128GA202-I/SP supports secure access control modules where the integrated crypto engine performs authentication for RFID, NFC, or BLE credentials without external secure elements. Its 32 MHz core completes HMAC and AES operations quickly enough to keep door-cycle latency under 200 ms, while 8 KB SRAM buffers credential lists. The 10-bit ADC reads tamper switches and supply monitors, and the SPDIP-28 through-hole package suits legacy access panel hardware that field technicians upgrade by replacing a single chip.
おすすめ
Low-Power Wireless Gateways
The PIC24FJ128GA202-I/SP works as a low-power wireless gateway controller that aggregates sensor frames over UART or SPI from a sub-GHz radio and forwards them to a backhaul modem. Its 128 KB Flash stores the gateway protocol stack plus a small web interface, while 7-channel DMA moves radio buffers into SRAM without CPU intervention. XLP sleep profiles drop the gateway into standby when no traffic is pending, and the SPDIP-28 package simplifies bench prototyping during gateway bring-up.

主な差別化要因

設計ノート
Estimated: At VDD = 3.3V and an active current of approximately 8 mA at 32 MHz, the PIC24FJ128GA202-I/SP dissipates about 26 mW. Decoupling the VDD/VSS pair with 100 nF X7R plus 10 uF bulk tantalum is recommended. Place the 100 nF within 3 mm of pin 16 and pin 15 to suppress switching noise.
Route the 32 kHz crystal traces to OSC1/OSC2 with short, symmetric paths and guard them with a ground ring. Keep digital switching signals away from the analog VDD/VSS pair and the ADC reference traces to minimize coupled noise during conversions. Leave room for ICSP test points on MCLR, ICSCLK, and ICSLAT to simplify in-circuit programming.
Do not assume the integrated crypto MCU activates per default — firmware must explicitly configure and key the engine before use. The internal RC oscillator is suitable for most tasks, but USB timing requires the precise primary oscillator. Avoid enabling unused peripherals in firmware to keep deep-sleep current at its minimum.
