PIC24FJ128GA308T-I/PT Обзор
What is a PIC microcontroller? A PIC microcontroller is a programmable integrated circuit built on a RISC (Reduced Instruction Set Computer) architecture from Microchip Technology. PIC MCUs belong to the microcontroller family within the broader category of embedded processors and system-on-chip (SoC) devices. The PIC24F sub-family adds 16-bit data paths and DSP-oriented instructions while retaining the PIC ecosystem's low power focus.
Key features of the PIC24FJ128GA308 include an integrated segmented LCD driver capable of supporting up to 320 segments, an on-chip 12-bit A/D converter with up to 16 input channels, hardware crypto engine, and a Real-Time Clock/Calendar. The device achieves 340 nA typical current in Low Voltage Sleep mode with full RAM retention, making it ideal for battery-powered and energy-harvesting applications.
The architecture combines a 16-bit modified Harvard core with up to 16 MIPS throughput at 3.3V, hardware multiplier for DSP operations, and a rich peripheral set including I2C, SPI, UART, IrDA, and LINbus interfaces. The device operates from 2.0V to 3.6V, supporting both 2.5V and 3.3V system rails commonly found in portable and industrial designs.
Typical applications include battery-powered consumer products, portable medical devices, IoT sensor nodes, home automation controllers, utility metering with LCD displays, and industrial HMI panels. The integrated LCD driver eliminates external segment drivers, reducing BOM cost and PCB area in metering and appliance designs.
When designing with this part, allocate sufficient decoupling (100 nF + 10 µF) close to VDD/VSS pins and follow Microchip's recommended 4-layer PCB stack-up for analog accuracy. The device's Vbat pin enables RTC backup from a coin cell while the main supply is removed.
This page consolidates distributor pricing, drop-in same-package alternatives, and practical design notes that go beyond what the manufacturer datasheet alone provides for engineering decision-making.

Типичное применение
PIC24FJ128GA308T-I/PT подходит для 6 применениеs: Battery-Powered Utility Meter with LCD, Portable Medical Monitoring Device, Home Automation HMI Controller, Industrial Sensor Hub with LCD Display, Wearable Fitness Tracker, IoT Edge Sensor Node.
Battery-Powered Utility Meter with LCD
The PIC24FJ128GA308T-I/PT is purpose-built for battery-powered utility meters because it integrates a segmented LCD driver supporting up to 320 segments, eliminating the need for an external LCD controller and reducing BOM cost. Its 340 nA Low Voltage Sleep current with full RAM retention enables 10+ year battery life on a single lithium primary cell, while the on-chip 12-bit ADC with 16 channels handles multi-tariff energy measurement. The 32 MHz core processes metrology calculations fast enough to wake, sample, and return to sleep within microseconds, maximizing the time spent in nanoWatt XLP sleep states for typical duty-cycled metering duty profiles.
Рекомендуется
Portable Medical Monitoring Device
The PIC24FJ128GA308T-I/PT fits portable medical monitoring applications where its nanoWatt XLP sleep modes stretch battery life between patient-charging cycles. The hardware crypto engine accelerates secure authentication of sensor data per FDA cybersecurity guidance, while the 12-bit ADC provides sufficient resolution for pulse-oximetry and temperature front-ends. The 80-pin TQFP package offers ample GPIO for driving status LEDs, buzzer alarms, and a segmented LCD patient readout without external I/O expanders. Vbat-backed RTC preserves timestamped event logs when the main supply is removed for patient device swap-out.
Рекомендуется
Home Automation HMI Controller
For home automation HMI panels, the PIC24FJ128GA308T-I/PT provides an integrated segmented LCD driver for status display plus a 32 MHz core to handle multi-protocol bridging between UART, SPI, and I2C sensor networks. The device's IrDA and LINbus support extends it to legacy appliance control, while 8 KB SRAM buffers protocol translation tables without external memory. Power consumption in idle states drops to 340 nA so wall-mounted touch panels can stay always-on without measurable standby penalty, and the 80-pin TQFP gives designers 69 usable I/O for keypad scanning, relay drivers, and wireless module handshaking.
Рекомендуется
Industrial Sensor Hub with LCD Display
The PIC24FJ128GA308T-I/PT serves industrial sensor hubs that aggregate multiple analog and digital sensors and display readings on a local segmented LCD. Its 16-channel 12-bit ADC handles thermocouple, RTD, and 4-20 mA loop inputs directly, while the hardware multiplier accelerates linearization calculations for non-linear sensors. The wide 2.0-3.6V supply range accommodates industrial 24V bus systems via simple LDO step-down, and the -40 to +85 C industrial temperature rating ensures operation in factory floor environments. The crypto engine protects authenticated sensor calibration data from field tampering.
Рекомендуется
Wearable Fitness Tracker
Wearable fitness trackers benefit from the PIC24FJ128GA308T-I/PT's nanoWatt XLP architecture, which keeps sleep current under 1 µA while preserving Bluetooth Low Energy link-layer timing. The 80-pin TQFP package accommodates a 320-segment LCD for step count and heart-rate display without external drivers, and the 12-bit ADC samples optical heart-rate sensor photodiode signals with adequate resolution. Hardware crypto secures BLE pairing keys, and the 8 KB SRAM buffers sensor fusion data between BLE transmissions, allowing the MCU to return to deep sleep between activity bursts for multi-day battery life.
Рекомендуется
IoT Edge Sensor Node
The PIC24FJ128GA308T-I/PT works in IoT edge sensor nodes where its nanoWatt XLP sleep modes dominate the energy budget for duty-cycled environmental monitoring. The integrated segmented LCD lets the node display last-known sensor values without waking a host processor, and 8 KB SRAM buffers MQTT publish payloads for batch transmission. Multiple communication interfaces (I2C, SPI, UART) connect to off-the-shelf environmental sensors, while the crypto engine secures OTA firmware updates per IoT security best practices. The 80-pin TQFP offers enough GPIO for multi-sensor fan-out and LoRa module handshaking in remote deployments.

Заметки по проектированию
Estimated: At 32 MHz active mode with all peripherals enabled, the PIC24FJ128GA308T-I/PT consumes approximately 15 mA at 3.3V. In Low Voltage Sleep with RAM retention, current drops to 340 nA typical. For battery life calculations, assume 0.1% active duty cycle (e.g., 1 ms active per second) to achieve average system current under 20 µA. Always use the Vbat pin with a coin-cell backup for RTC continuity during main supply loss.
Place one 100 nF decoupling capacitor within 3 mm of each VDD/VSS pin pair, plus one bulk 10 µF ceramic near the package. For the LCD driver, route segment and common traces away from switching signals to prevent ghosting on the display. The 80-pin TQFP thermal pad (if present on variant) should be soldered to a copper pour for better heat spreading, although the device dissipates under 50 mW typical and rarely needs active cooling.
Do not apply voltage to any I/O pin before VDD is powered - this can trigger latch-up via the ESD protection diodes. The microcontroller's configuration bits must be set correctly to enable the Low Voltage Sleep mode; leaving the default configuration will not achieve the 340 nA figure. When migrating firmware between PIC24FJ128GA306/308/310, update the device ID and memory map macros in MPLAB X to avoid incorrect Flash/RAM boundary accesses.
