PIC24FJ64GA310-I/PT - 16-bit 32MHz 64KB Flash MCU 100-TQFP | Microchip

The Microchip Technology PIC24FJ64GA310-I/PT is a 16-bit PIC® microcontroller featuring nanoWatt XLP (eXtreme Low Power) technology, delivering 32 MHz (16 MIPS) performance with 64 KB Flash and 8 KB RAM in a 100-pin TQFP (12x12 mm) package. The device integrates a 16-bit CPU, full-speed USB 2.0-compliant transceiver, an LCD controller, a 10-bit A/D converter (with 24 channels at this pin count) and a hardware crypto engine. What is a 16-bit microcontroller? A 16-bit MCU is a single-chip computer with a 16-bit data path that executes arithmetic and logic operations on 16-bit words per instruction, sitting between 8-bit controllers and 32-bit ARM Cortex-M cores in the embedded hierarchy. Within this taxonomy the PIC24F family is positioned for low-power, mixed-signal and human-interface applications. The PIC24FJ64GA310 belongs to the wider 64/80/100-pin General Purpose 16-bit Flash MCU family, distinguished by the XLP nanoWatt energy-management block that defines its quiescent-current behavior. Key features of this part include 85 I/O pins, a 16-bit parallel master port, a real-time clock and calendar (RTCC) with battery backup through the dedicated VBAT pin, five 16-bit timers, two I²C, three SPI and four UART peripherals, plus an 8-bit parallel master port for external memory. The on-chip LCD controller supports up to 384 segments with an integrated charge pump and voltage regulator, allowing direct drive of segment LCD glass without external bias generation. Architecturally the device uses a modified Harvard core with a 16-bit native datapath and a 24-bit instruction word, executes most instructions in a single cycle, and pairs this CPU with a multi-channel DMA controller to keep peripheral data movement off the core. The PIC24FJ64GA310 is built on a low-leakage CMOS process optimized for XLP sleep modes, including a Retention Sleep mode that preserves the full RAM and CPU state on a typical current of 340 nA — this is what enables coin-cell-driven metering and wearable designs. Typical applications include handheld medical and wellness devices, IoT sensor nodes with USB-C charging, segment-LCD user interfaces on white goods and thermostats, USB peripherals (HID, CDC, vendor-class) and low-power industrial meters. The wide operating voltage (2.0 V – 3.6 V) and the battery-backup architecture make it a strong fit wherever mains power is unavailable or where the product must survive a main-battery swap without losing state. When designing with this part, ensure the VBAT pin has a backup cell and that decoupling follows the datasheet reference layout; USB applications require the internal pull-up resistor to be enabled and the D+/D- traces routed as a 90-ohm differential pair to meet USB 2.0 signaling compliance.

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.

Operating voltage spans 2.0 V to 3.6 V across an industrial -40C to +85C temperature range. A 16-bit microcontroller (MCU) is a programmable processor that executes instructions on 16-bit-wide data paths, occupying the middle ground between 8-bit MCUs (low cost, simple control) and 32-bit MCUs (high performance, complex OS). The PIC24F family specifically targets low-power embedded applications where 8-bit parts lack peripherals or DSP capability, but 32-bit ARM Cortex-M parts are over-spec or power-hungry. PIC24F belongs to the broader category hierarchy: 16-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. Key differentiating features include hardware DMA that offloads memory-to-peripheral transfers from the CPU, ECC Flash for improved reliability in harsh environments, and dedicated CTMU hardware that simplifies capacitive touch button and slider implementations. The integrated 12-bit ADC at 200 ksps with 14 channels handles multiple sensor inputs without an external ADC, while the three analog comparators enable fast threshold detection for power and signal monitoring. Architecturally, the PIC24FJ64GA702 uses a modified Harvard architecture with separate program and data buses, a 16x16 hardware multiplier, and a barrel shifter, enabling single-cycle MAC operations suited for digital signal processing tasks such as audio codecs, sensor filtering, and motor control loops. The XLP technology with multiple deep-sleep modes typically draws under 1 uA in sleep, extending battery life in IoT endpoints. Typical applications include low-power IoT sensor nodes, capacitive touch user interfaces, battery-powered medical wearables, industrial control panels, USB peripherals, and consumer appliances requiring mixed-signal integration. The wide operating voltage and industrial temperature grade also suit automotive aftermarket and HVAC controller designs. When designing with this device, ensure the exposed pad on the bottom of the UQFN package is soldered to a sufficiently large copper pour (at least 16 thermal vias recommended) for thermal dissipation and ground reference. Configure the oscillator with appropriate PLL settings and use the internal 8 MHz fast RC oscillator as a fail-safe backup to the external crystal.

It integrates a 12-bit ADC at 200 ksps with up to 14 analog inputs, 3 comparators, a Charge Time Measurement Unit (CTMU) for capacitive touch sensing, and a DMA controller, targeting low-power embedded designs. What is a 16-bit microcontroller? A 16-bit microcontroller is a single-chip computer whose CPU datapath and ALU natively process 16-bit data words, offering a balance between 8-bit MCUs (lower cost, lower power) and 32-bit MCUs (higher throughput, richer peripherals). The PIC24F family is a 16-bit MCU -> microcontroller -> embedded processor -> semiconductor hierarchy, designed by Microchip as a low-power, mid-performance step-up from the PIC16 and PIC18 families and a step-down from PIC32 32-bit parts. Key features include 64KB (22K x 24 instruction words) Flash program memory with Error-Correcting Code (ECC) for improved reliability, 16KB SRAM, multiple low-power sleep modes (Idle, Doze, Sleep, Deep Sleep), peripheral pin select (PPS) for flexible I/O mapping, and 5V-tolerant digital inputs on a 3.3V core. Communication peripherals include UART, SPI, I2C, and parallel PMP, supporting a wide range of sensors and human-interface peripherals. The architecture is a modified Harvard RISC design with a 16-bit instruction word and 24-bit instruction width, providing deterministic interrupt latency and C-compiler-friendly instruction set. The CTMU enables capacitive touch buttons, sliders, and proximity sensing without external touch ICs, while the 12-bit 200 ksps ADC supports sensor conditioning and battery monitoring simultaneously with touch scanning via DMA. Typical applications include low-power IoT sensor nodes, capacitive touch user interfaces (white goods, automotive HMI, consumer electronics), battery-powered medical devices such as glucose meters and portable monitors, industrial control panels with segmented displays, and USB-CDC/HID human-interface peripherals. The 48-pin UQFN footprint balances compactness (6x6 mm) with sufficient I/O for mid-complexity designs. When designing with this part, consider the 2.0V-3.6V VDD range, plan for the 20ms POR/PWRT startup window, and reserve one ADC channel for bandgap-based VDD measurement to enable software battery monitoring. For touch applications, allocate the CTMU and place sense traces symmetrically to minimize noise coupling.
