PIC24FJ128GL406-E/MR 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and peripherals. The PIC24F 'GL4' family specifically targets ultra-low-power embedded applications, combining a 16-bit modified Harvard architecture with sleep currents in the few-hundred-nA range while retaining RAM. This hierarchy places it as: microcontroller -> embedded MCU -> ultra-low-power MCU -> 16-bit PIC -> PIC24FJ GL4 family. Compared with 8-bit MCUs, PIC24F devices deliver higher MIPS-per-mW and richer CIP (Core Independent Peripherals) such as the segmented LCD driver and USB.
Key features include 128KB (128K x 8) ECC Flash with Dual Partition for live Over-The-Air firmware updates, 32KB RAM, 60 I/O pins (from the 64-pin package), and integrated peripherals: USB 2.0 full-speed, segmented LCD controller, multiple UART/SPI/I2C, 12-bit ADC, and CIPs that offload tasks from the CPU. The 'GL4' family supports EEPROM emulation and animation features for the LCD driver, useful in user-interface-heavy IoT nodes.
The device operates across -40C to +125C (E = Extended temperature grade), supports 2.0V-3.6V, and uses a 32 MHz internal oscillator with PLL. Hardware math acceleration, DMA, and configurable logic cells (CLC) enable efficient peripheral interconnection. Security features include Flash code-protect and a unique device ID.
Typical applications include IoT sensor hubs, home automation controllers, medical glucose/patient monitors with LCD, industrial HMI, USB-CDC/HID peripherals, and battery-powered metering. The dual-partition OTA Flash is particularly attractive for field-deployed firmware upgrades.
Design with this MCU by budgeting the 32KB RAM across the LCD frame buffer, USB descriptors, and application heap; use ECC Flash for safe OTA rollback. Place a 1uF + 100nF decoupling pair near each VDD/VSS pin pair and route the 32 kHz secondary oscillator traces short to avoid RTC drift.

主な用途
PIC24FJ128GL406-E/MR の用途: 6 件s: IoT Sensor Hub with OTA Updates, Medical Glucose/Patient Monitor with LCD, Industrial HMI Controller, USB HID / CDC Data-Acquisition Dongle, Battery-Powered Smart Meter, Home Automation / Smart-Home Gateway Node.
IoT Sensor Hub with OTA Updates
The PIC24FJ128GL406-E/MR is engineered for battery-powered IoT sensor hubs thanks to its dual-partition 128KB ECC Flash that supports live Over-The-Air firmware swaps without service interruption, plus few-hundred-nA sleep current with full 32KB RAM retention per the Microchip PIC24FJ GL4 datasheet. It integrates USB 2.0 full-speed for tethered provisioning, segmented LCD for local status display, and 60 GPIO for sensor fan-out. Designers can run an RTOS or Microchip's MPLAB Harmony at 16 MIPS / 32 MHz and wake on peripheral events via the RTCC and CLC (Configurable Logic Cell) CIPs to keep average current under 50 uA.
おすすめ
Medical Glucose/Patient Monitor with LCD
In medical glucose meters, pulse oximeters, and patient wearables, the PIC24FJ128GL406-E/MR drives the segmented LCD directly (up to 64 segments, 1/8 duty) without an external driver IC, shrinking BOM and lowering quiescent draw. ECC Flash protects patient log integrity, while the 12-bit ADC and CIPs handle sensor conditioning. The Extended -40C to +125C temperature grade supports IEC 60601-1 environmental tests, and the few-hundred-nA sleep enables coin-cell operation across multi-month dosing logs.
おすすめ
Industrial HMI Controller
The PIC24FJ128GL406-E/MR serves as the HMI controller for industrial panels where a 64-segment segmented LCD plus capacitive-touch buttons via the CLC and 12-bit ADC replace mechanical keys. The DMA engine streams LCD frame-buffer updates from the 32KB RAM without CPU intervention, freeing the 16 MIPS core for Modbus or CANopen logic via UART. The 64-QFN (9x9) package suits high-vibration mounting where leaded parts would fatigue.
おすすめ
USB HID / CDC Data-Acquisition Dongle
Engineers select the PIC24FJ128GL406-E/MR for USB-CDC/HID data-acquisition dongles because the on-chip USB 2.0 full-speed transceiver, 16-MIPS throughput, and 32KB RAM eliminate an external PHY and support high-speed bulk transfers. DMA moves ADC samples directly into USB endpoint RAM while the CIPs sustain timing. USB bus-powered operation is straightforward via the internal 3.3V regulator, and 128KB Flash accommodates multi-protocol firmware stacks.
おすすめ
Battery-Powered Smart Meter
Battery-powered electricity, water, and gas meters benefit from the PIC24FJ128GL406-E/MR's segmented LCD (for kWh digits and icons), few-hundred-nA sleep with RAM retention, and 16 MIPS core for metrology math. The RTCC with 32 kHz crystal domain keeps time-of-use tariffs accurate while the MCU sleeps, and the integrated 12-bit ADC handles sensor inputs. OTA via dual-partition Flash enables regulatory tariff updates without site visits.
おすすめ
Home Automation / Smart-Home Gateway Node
As a smart-home node, the PIC24FJ128GL406-E/MR aggregates sensor data over I2C/SPI/UART, exposes a USB-CDC provisioning port, and displays status on its integrated segmented LCD. The 32KB RAM hosts a small TCP/IP stack via the on-chip peripheral set, while 128KB Flash accommodates Matter, Zigbee, or proprietary stacks. The Extended temperature grade ensures reliability in unheated attics or basements.

設計ノート
Power the PIC24FJ128GL406-E/MR from a clean 2.0-3.6 V supply with a 1 uF + 100 nF decoupling pair within 5 mm of each VDD/VSS pin. For battery-powered designs, the internal 3.3V LDO can supply the core from a single Li-ion cell; verify that peak USB inrush (per USB 2.0 spec) does not sag VDD below 2.7V or USB enumeration fails. Place a 4.7 uF bulk cap on VBUS when running USB bus-powered.
Keep the 32.768 kHz secondary oscillator traces under 5 mm and guard them with a ground ring to avoid RTC drift in metering designs. Route the USB D+/D- pair as a 90-ohm differential with length matching within 2 mm, and place the USB series ferrite near the connector. Expose the exposed pad of the 64-QFN package with at least 8 thermal vias to a 1 oz copper pour for ground and thermal dissipation.
Do not exceed VDD 3.6 V or the on-chip brown-out reset may mis-trigger. Configure unused I/O as outputs (not inputs) to avoid shoot-through in sleep mode. When using dual-partition Flash OTA, always validate the new image's CRC32 in the bootloader before swapping partitions, otherwise a corrupted OTA can brick the device in the field.
Estimated: at 32 MHz / 3.3 V active, the PIC24FJ128GL406-E/MR core draws around 8-15 mA typical; the 64-QFN 9x9 mm package with 8-via thermal pad holds theta_JA near 30 C/W. At 85C ambient the junction rises 20-30C, well within the +125C Extended limit. For sealed enclosures, derate by 10-15%.
