PIC24FJ128GA310T-I/PT 개요
A 16-bit microcontroller is a microprocessor core with a 16-bit data path, program counters, and ALU, offering a meaningful step up from 8-bit MCUs in code density, arithmetic precision, and interrupt handling while remaining simpler and lower-cost than 32-bit Cortex-M parts. The PIC24FJ family is the general-purpose branch of Microchip's PIC24F line, sitting in the broader hierarchy of microcontroller -> embedded controller -> semiconductor. The GA310 sub-family adds a segmented LCD driver and Vbat backup-domain features tailored for battery-powered human-interface products.
Key features include 128KB flash (43K x 24 organization), 8KB SRAM, up to 85 I/O pins, a segmented LCD driver supporting up to 480 segments, USB 2.0 full-speed OTG, multiple UART/SPI/I2C peripherals, 16-bit timers, a 10-bit 1.1 MSPS A/D converter, and nanoWatt XLP power management with deep sleep, sleep, idle, and doze operating modes. The PT package provides 100 TQFP pins for ample peripheral expansion on a moderate-density 0.5 mm pitch footprint.
The PIC24FJ128GA310 architecture uses a 16-bit modified-Harvard RISC core with 24-bit instructions and 16-bit data paths, enabling 16 MIPS throughput at 32 MHz and C-friendly compiler support through MPLAB XC16. The integrated LCD controller with on-chip charge pump and contrast stabilization reduces BOM cost, while Vbat backup with RTCC retention keeps the real-time clock alive during main-rail loss.
Typical applications include battery-powered medical devices such as glucose meters and portable patient telemetry, industrial HMI panels with on-board segmented displays, home automation controllers, electronic shelf labels, low-power wireless sensor hubs, and metering products requiring long battery life and on-board LCD glass. The 340 nA sleep retention with RAM preservation makes it well suited for products that sleep 99% of the time.
When designing with this part, route the segmented LCD signals to dedicated pins and follow the Microchip application note on LCD board layout to minimize ghost segments. Provide a clean 2.0V-3.6V supply, watch the ADC acquisition timing carefully, and use the ULPBOR for brown-out protection in battery applications.

일반적인 애플리케이션
PIC24FJ128GA310T-I/PT 적합 용도: 6 애플리케이션s: Battery-Powered Medical Devices, Industrial HMI Panels with LCD, Home Automation Controllers, Electronic Shelf Labels (ESL), Portable Metering and Data Loggers, Low-Power Wireless Sensor Hubs.
Battery-Powered Medical Devices
The PIC24FJ128GA310T-I/PT is well suited to battery-powered medical devices such as glucose meters, pulse oximeters, portable patient monitors because of its 340 nA Sleep current with full RAM retention and integrated segmented LCD controller for direct glass connection. The 2.0V-3.6V supply range supports single-cell lithium and two-AAA alkaline chemistries, enabling multi-year battery life when the device wakes only briefly to take a measurement. The 16 MIPS core runs the full signal-processing pipeline for sensor acquisition and algorithm execution within tight latency budgets while keeping average current in the microamp range.
추천
Industrial HMI Panels with LCD
Use the PIC24FJ128GA310T-I/PT in industrial HMI panels with on-board segmented LCD glass where the integrated LCD controller drives up to 480 segments without an external driver. The combination of 128 KB flash, 85 I/O, and the Vbat pin with RTCC retention keeps the display and clock alive across main-rail loss, which is essential for fault loggers and event recorders. The 32 MHz / 16 MIPS core executes keypad debouncing, menu navigation, and Modbus protocol stacks in real time without external DSP or logic.
추천
Home Automation Controllers
The PIC24FJ128GA310T-I/PT is ideal for home automation hubs and thermostat controllers where on-glass display, low standby power, and USB device connectivity for commissioning all matter. The 340 nA Sleep current allows multi-year battery life on wireless room sensors, and the integrated USB 2.0 Full-Speed OTG supports field updates and direct PC configuration without external bridges. With 8 KB SRAM, the device handles Zigbee or sub-GHz wireless protocol stacks via SPI-attached radios while keeping responsive UI on the segmented display.
추천
Electronic Shelf Labels (ESL)
The PIC24FJ128GA310T-I/PT powers electronic shelf labels where multi-year battery life, integrated segmented LCD driver, and 2.0V-3.6V supply range from coin cells or printed batteries are decisive. The Sleep mode with 340 nA retention keeps the label showing the last price while the wireless link is dormant, and the device wakes briefly for RF refresh cycles. The Vbat pin with RTCC retention lets the label maintain accurate time-of-day pricing across main-rail battery swaps.
추천
Portable Metering and Data Loggers
The PIC24FJ128GA310T-I/PT is well suited to portable utility meters, environmental data loggers, and field instruments where the segmented LCD shows instantaneous readings and a 128 KB flash history buffer stores months of samples. The 340 nA Sleep current with RAM retention lets the device sleep between samples while preserving the data buffer and real-time clock, dramatically extending field deployment intervals. The 10-bit 1.1 MSPS ADC handles sensor front-ends directly, and the USB OTG port enables fast data offload in the lab without an external bridge.
추천
Low-Power Wireless Sensor Hubs
Deploy the PIC24FJ128GA310T-I/PT as the host MCU in low-power wireless sensor hubs that combine sub-GHz or Bluetooth Low Energy radios with on-glass segment displays for local readout. The 16 MIPS core runs the wireless protocol stack and sensor-processing algorithms while the integrated LCD driver shows live readings and connection status without an external display IC. The 340 nA Sleep current and Vbat backup keep the hub responsive across battery changes, while the USB OTG port enables direct PC tethering for firmware updates and commissioning.

설계 노트
Use the nanoWatt XLP Sleep mode with RTCC and RAM retention to reach 340 nA typical standby current. Configure the ULPBOR (Ultra-Low-Power Brown-Out Reset) for battery applications to ensure deterministic restart on voltage droop. Provide bulk decoupling of 10 uF ceramic plus 0.1 uF high-frequency bypass on VDD within 5 mm of the package pins to handle the inrush during Sleep-to-active transitions.
Route segmented LCD signals to dedicated pins and follow Microchip application note AN1368 for LCD board layout to minimize ghost segments and AC coupling. Keep LCD traces short, surrounded by ground, and isolated from switching signals. Place the VLCD charge-pump capacitors close to the VLCD pins and use the charge-pump mode rather than external resistive bias to reduce BOM cost.
Do not exceed the absolute maximum VDD of 3.6 V even in USB-active mode; if the design includes USB, route the internal 3.3 V USB regulator output to VUSB and add 0.1 uF plus 10 uF decoupling per the family datasheet. Configure the PLL carefully when USB is enabled (48 MHz USB clock requires specific PLL divider ratios) - misuse causes USB enumeration failures. Always enable the RTCC write-protection lock bits in production firmware to prevent accidental time loss.
