PIC24FJ192GA108T-I/PT 概要
What is a PIC24F microcontroller? A PIC24F is a 16-bit RISC microcontroller from Microchip that sits in the hierarchy: microcontroller (MCU) -> 16-bit MCU -> flash MCU -> low-power MCU -> PIC24F family. It is the lower-power complement to the dsPIC/PIC24H line, and is engineered for battery-friendly applications where 8-bit PICs lack memory or peripheral bandwidth but the system does not need a DSP engine. The 'F' suffix denotes Flash program memory and the 'J' denotes the nanoWatt XLP-style ultra-low-power process.
Key features include 192 KB self-reprogrammable flash, 16 KB SRAM, an operating voltage range of 2.0 V to 3.6 V with 5.5 V tolerant digital inputs, three I2C, three SPI, four UART, and 23 independent timers. The device supports multiple power management modes (Sleep, Idle, Doze) with fast wake-up, configurable open-drain outputs, and high-current 18 mA sink/source capability on every I/O pin. It also integrates a Parallel Master Port (PMP) for off-chip memory or graphics expansion.
Architecturally, the PIC24FJ192GA108T-I/PT uses a modified Harvard architecture with a 16-bit datapath and 24-bit instruction word. The CIP (Core Independent Peripherals) approach allows hardware state machines to handle timing-sensitive tasks without CPU intervention, reducing active time and current draw. The 32 MHz core delivers 16 MIPS of throughput while operating from as low as 2.0 V.
Typical applications include industrial control and HMI panels, portable medical instrumentation, low-power sensor hubs, USB and serial gateway bridges, and battery-backed telemetry devices. The 16 KB RAM buffer is particularly useful for protocol stacks and audio sample buffering in DSP-lite workloads.
Designers should pay attention to the 2.0-3.6 V supply constraint and avoid 5 V system buses unless using the 5.5 V tolerant digital inputs. Decoupling requires at least one 100 nF ceramic capacitor per VDD/VSS pair plus a bulk 10 µF near the ICSP programming header. For firmware development, MPLAB X IDE with the XC16 compiler is the standard toolchain.

主な用途
PIC24FJ192GA108T-I/PT の用途: 6 件s: Industrial HMI Control Panels, Portable Medical Instrumentation, Battery-Backed Sensor Hubs, Serial Protocol Bridges and Gateways, Automotive Body and Comfort Modules, Consumer Audio and Display Peripherals.
Industrial HMI Control Panels
The PIC24FJ192GA108T-I/PT's 192 KB Flash and 16 KB RAM comfortably host full graphical HMI state machines, while the Parallel Master Port interfaces directly to TFT LCD drivers or external SRAM for framebuffering. Its four UART channels support simultaneous RS-232/RS-485 field-bus links, and three SPI buses drive digital potentiometers, DACs, and isolated comms. Industrial-grade -40C to +85C operation suits factory floor deployment without extra thermal hardening.
おすすめ
Portable Medical Instrumentation
Sub-100 nA standby and fast wake-up Sleep/Idle modes let the PIC24FJ192GA108T-I/PT run on coin-cell or Li-ion packs for pulse oximeters, glucose meters, and bedside monitors. The 16 KB RAM holds raw sensor sample buffers, while the 18 mA I/O drive directly energizes LED arrays, piezo buzzers, and segmented LCDs. Five-volt-tolerant digital inputs simplify interfacing with legacy hospital bus transceivers without level shifters.
おすすめ
Battery-Backed Sensor Hubs
The PIC24FJ192GA108T-I/PT is ideal for wireless sensor hubs aggregating data from multiple SPI or I2C sensor chains. Its 32 MHz throughput and DMA-driven peripherals can sample multi-axis IMUs, environmental sensors, and gas sensors concurrently while leaving CPU bandwidth for stack processing. The 192 KB Flash hosts full 6LoWPAN or BLE HCI host code, and 5.5 V tolerant inputs ease integration with industrial 5 V sensor rails.
おすすめ
Serial Protocol Bridges and Gateways
Three I2C, three SPI, and four UART channels let the PIC24FJ192GA108T-I/PT act as a multi-protocol bridge between Modbus RTU, I2C sensor clusters, SPI displays, and Ethernet or cellular modems. The 16 KB RAM supports protocol translation buffers, while the 32 MHz core runs Modbus, MQTT-SN, and proprietary protocols in parallel. CIP (Core Independent Peripherals) handle UART framing and CRC without CPU load.
おすすめ
Automotive Body and Comfort Modules
Although not AEC-Q100 qualified, the PIC24FJ192GA108T-I/PT's industrial -40C to +85C range and CIP peripherals are used in non-safety body modules such as seat controllers, mirror adjusters, and ambient lighting. The 18 mA I/O drive directly powers LED drivers and small relays, while three SPI buses drive CAN-transceiver-equipped peripherals. For AEC-Q100 requirements, designers migrate to the PIC24HJ or dsPIC33 families.
おすすめ
Consumer Audio and Display Peripherals
The PIC24FJ192GA108T-I/PT's high-current 18 mA I/O lines can source LED strings and segmented LCD bias rails directly, while the three SPI ports drive audio DACs, AMOLED controllers, and SD cards. 16 KB RAM buffers audio sample frames for software codecs, and the 32 MHz core handles UI rendering with a small TFT. The PMP (Parallel Master Port) interfaces to 8/16-bit parallel LCDs without external glue logic.

設計ノート
The PIC24FJ192GA108T-I/PT requires four VDD/VSS pairs (pins 11/12, 32/33, 54/55, 76/77) properly decoupled with 100 nF X7R ceramic capacitors placed within 3 mm of each pair. Add a bulk 10 uF tantalum or ceramic capacitor near the ICSP programming header to suppress inrush during flash programming. The 2.0 V to 3.6 V supply must remain within tolerance during Sleep-mode wake-up transients, where the FRC stabilizes within 10 us.
Do not apply voltages above 3.6 V to VDD even though digital inputs tolerate 5.5 V. A common mistake is powering the MCU from a 3.3 V LDO and switching 5 V signal lines - this works for inputs but the absolute maximum on any analog pin (AVDD) is still 3.6 V. Use the ADC only with 0 to VDD analog rails, and configure the band-gap reference selection carefully if using external VREF+.
Route the ICSP pins (RB6/ICSPCLK and RB7/ICSPDAt) as a dedicated 2-wire bus with no series resistors above 100 ohm and keep traces under 50 mm to ensure reliable in-circuit programming. Avoid routing high-speed signals under the MCU's exposed pad (note: TQFP-80 has no EP, but DQFN variants do). The 80-pin TQFP allows 0.5 mm pitch routing on a 4-layer board with 4 mil traces and 4 mil spacing.
