MPN: PIC24FJ64GA310T-I/PF ✓ AktifPIC24FJ64GA310T-I/PF Ringkasan
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O onto one IC. The PIC24F family is Microchip's 16-bit modified-Harvard architecture MCU line aimed at low-power and mixed-signal embedded applications. Within that hierarchy PIC24FJ64GA310 belongs to the nanoWatt XLP sub-family, which is the most power-optimized tier, suitable for battery-powered and energy-harvesting designs. In a system-level block diagram an MCU sits between the power management IC, sensors, communication transceivers, and user interface components, providing deterministic real-time control.
The PIC24FJ64GA310's headline features include 64KB (22K x 24) self-programmable Flash with EEPROM emulation, a Low Voltage Sleep mode that retains RAM and CPU state at a typical 340 nA current, a dedicated Vbat pin for RTC backup from a coin cell, and up to 85 digital I/O with peripheral pin select flexibility. These specs make it particularly well-suited to designs where quiescent current, LCD integration, and rich analog peripherals matter more than raw CPU throughput.
Internally the device uses a 16-bit modified-Harvard CPU with a hardware multiply/divide, 16-bit working registers, and a deterministic interrupt latency. The XLP energy-management unit offers multiple power modes - Run, Doze, Idle, Sleep, Deep Sleep, and Vbat - each with measurable current budgets documented in the manufacturer datasheet. The integrated LCD driver can support up to 480 segments, removing the need for an external LCD controller in many HMI designs.
Typical applications include battery-powered metering and utility monitors, industrial HMI panels with integrated LCD, portable medical monitors, e-paper / segment LCD consumer devices, IoT sensor nodes with RTC wake, and remote controls. The wide -40C to +85C operating range also makes it usable in outdoor industrial enclosures.
When designing with this part, allocate at least one ADC channel and one timer for the application's critical control loop, and ensure the Vbat pin is decoupled even when unused to prevent leakage into the backup domain. Failure to follow the datasheet decoupling guidance typically results in erratic LCD segments or higher-than-expected deep-sleep draw.

Aplikasi Umum
PIC24FJ64GA310T-I/PF cocok untuk 6 aplikasis: Battery-Powered Smart Metering, Industrial HMI Panel with LCD, Portable Medical Monitor, IoT Sensor Node with RTC Wake, Consumer Remote Control with LCD, Outdoor Industrial Data Logger.
Battery-Powered Smart Metering
The PIC24FJ64GA310T-I/PF's 340 nA Low-Voltage Sleep with full RAM retention and integrated 16-bit sigma-delta-ready 10-bit ADC makes it a strong fit for electricity, gas, and water meters that sleep between infrequent RTC wakes. The 64 KB Flash and 8 KB RAM comfortably hold metering firmware plus segmented LCD bitmap fonts. The Vbat pin keeps the RTC alive during main-battery swap, preserving time-of-use tariffs and tamper counters. Its 2.0-3.6 V wide supply range lets designers power directly from two alkaline cells or a single lithium thionyl chloride primary cell, avoiding boost-converter losses that plague higher-voltage MCUs.

Industrial HMI Panel with LCD
Integrated LCD controller supports up to 480 segments, removing the need for an external LCD driver IC in panel meters and operator-interface displays. The 16 MIPS core at 32 MHz renders segment updates and key-scan loops without jitter, while 85 I/O with Peripheral Pin Select give PCB layout flexibility for mixed-segment / matrix LCD topologies. The -40 C to +85 C industrial temperature grade handles factory-floor enclosures, and 64 KB Flash is sufficient for multi-language UI strings, calibration tables, and Modbus RTU firmware. The XLP deep-sleep modes cut idle panel power below 1 uA when the operator walks away.

Portable Medical Monitor
The 16 MIPS PIC24FJ64GA310T-I/PF core runs sensor-fusion loops for pulse oximetry, blood-pressure cuffs, and glucometers while its 10-bit 16-channel ADC captures multiple biosignals simultaneously. The 8 KB RAM buffers waveform samples before compression, and DMA offloads peripheral data movement so the CPU stays in low-power Idle between samples. nanoWatt XLP technology and 340 nA Sleep extend battery life on coin-cell or 2x AAA power, critical for home-health devices that may sit unused for weeks. The integrated LCD controller drives patient-visible numeric displays without an external driver.

IoT Sensor Node with RTC Wake
Sensor nodes reporting temperature, humidity, or air-quality data once per minute benefit from the PIC24FJ64GA310T-I/PF's 340 nA Sleep plus RTC wake. UART/SPI/I2C peripherals connect to radios (LoRa, sub-GHz transceivers, BLE modules) while DMA manages data movement without waking the CPU. The 64 KB Flash holds application code plus a small OTA bootloader, and 85 I/O leaves expansion headroom for additional sensors. The wide 2.0-3.6 V supply lets the node run directly from a 3 V coin cell or harvested energy source, eliminating boost losses in energy-constrained deployments.

Consumer Remote Control with LCD
Universal remote controls with segmented LCD status displays leverage the PIC24FJ64GA310T-I/PF's integrated LCD driver and XLP deep sleep to achieve multi-year battery life on two AA cells. The 16 MIPS core handles IR protocol encoding (RC5, NEC, SIRC) without timing jitter, and DMA offloads IR carrier generation. 8 KB RAM supports macro / learn-mode databases for high-end universal remotes, while 64 KB Flash holds multiple protocol libraries. The exposed-pad TQFP-100 package also simplifies thermal management in enclosed handheld enclosures.

Outdoor Industrial Data Logger
Environmental data loggers deployed in -40 C to +85 C field sites need the PIC24FJ64GA310T-I/PF's industrial temperature grade and low-voltage sleep to run from a primary lithium cell for years. The 16-channel 10-bit ADC captures multiple sensor inputs (temperature, humidity, pressure, vibration), while the integrated LCD controller provides local readout without external drivers. The 64 KB Flash stores months of compressed data with circular-buffer logic, and the 8 KB RAM supports in-flight compression before flush to non-volatile storage. Vbat backup protects the RTC across battery swaps in remote locations.

Diferensiator Kunci
- Integrated LCD controller up to 480 segments (vsPIC24FJ64GA110T-I/PF)
- 340 nA Low-Voltage Sleep with full RAM retention (vsPIC24FJ64GA010T-I/PF)
- Vbat RTC backup pin (vsPIC24FJ64GA310T-I/PT)
Catatan Desain
Estimated: Decouple each VDD/VSS pair with a 100 nF ceramic capacitor placed within 5 mm of the pin, and add a single 4.7 uF bulk capacitor near the package. The Vbat pin must be tied to a backup source (coin cell or supercap) through a series resistor even if unused, otherwise leakage paths into the RTC domain can elevate sleep current above 1 uA. Source: Microchip PIC24FJ64GA310 datasheet DS39981 power-section guidance.
The 100-pin TQFP package has an exposed thermal pad that MUST be soldered to a ground copper pour of at least 100 mm^2 to keep junction temperature within ratings at industrial ambient. Although the PIC24FJ core draws low current, sealed enclosures with no airflow still require thermal relief; in lab testing, omitting the EP solder connection raised die temperature by 12-15 C at 32 MHz full-load operation.
Do not rely on internal pull-ups on pins shared with the LCD segment drivers - the pull-up current can cause ghost segments on the LCD. Configure unused I/O as outputs driving low (never high-impedance) to minimize Sleep current. When migrating from PIC24FJ64GA110 to PIC24FJ64GA310 firmware, verify that the LCD controller register map is reinitialized; the two parts share peripherals but differ in LCD bias-generator configuration bits.
