PIC24FJ64GA104-I/ML

PIC24FJ64GA104-I/ML - 16-Bit 32MHz 64KB Flash MCU | Microchip

The Microchip PIC24FJ64GA104-I/ML is a 16-bit PIC® XLP™ 24F microcontroller running at 32 MHz with 64 KB Flash program memory, 8 KB RAM, and a 44-pin QFN (8x8 mm) package with exposed pad. The /ML suffix indicates industrial temperature range (-40C to +85C) and a QFN surface-mount form factor. A 16-bit microcontroller (MCU) is a programmable processor that uses a 16-bit data path and instruction set, sitting in the hierarchy: 16-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. PIC24F devices from Microchip are mid-range 16-bit MCUs that bridge 8-bit PIC® parts and 32-bit PIC32 parts, offering higher computational throughput and richer peripherals than 8-bit parts while remaining easier to use than ARM Cortex-M parts in many low-power designs. The 'FJ' series adds nanoWatt XLP extreme low-power technology, which makes the family well suited to battery-powered products. Key features include a 32 MHz MIPS16e core delivering up to 16 MIPS, a 10-bit ADC with up to 13 channels, multiple UART/SPI/I2C peripherals, a hardware RTCC, and nanoWatt XLP sleep currents in the microamp range. The 64 KB Flash supports self-programming and the 8 KB SRAM provides ample workspace for TCP/IP stacks such as Microchip's free MPLAB® Harmony networking libraries. The 44-QFN package provides a small 8 mm x 8 mm footprint and uses an exposed thermal pad to reduce junction-to-PCB thermal resistance for higher-power peripherals. Architecture-wise the PIC24FJ64GA104 is built on a modified Harvard architecture with separate program Flash and data SRAM buses, plus a 16-bit instruction word that allows single-cycle 16-bit ALU operations. The peripheral set includes five 16-bit timers, comparators, a charge-time-measurement-unit (CTMU) for touch and capacitance sensing, and parallel master port (PMP) for external bus interfaces. This combination makes the part unusually flexible for its small pin count. Typical applications include portable consumer devices, IoT sensor nodes, low-power wireless sensor hubs, industrial control panels, and USB-CDC/HID human-interface peripherals. Industrial automation front-ends, e-paper / segment LCD control, and battery-powered data loggers also commonly use this family. Design consideration: leverage the XLP sleep modes (typically <1 uA in deep sleep with RTCC running) and use the internal 8 MHz fast RC oscillator with PLL to maximise active-mode performance while still achieving nanoWatt-level standby. Always expose the thermal pad on the QFN to a continuous ground pour with multiple thermal vias for best thermal and EMI performance. This page synthesizes distributor pricing, drop-in alternative MPNs (with same-brand priority), and practical design notes not found in the manufacturer datasheet alone, all anchored to Microchip's published 39951C family data sheet (DS39951C).

It is housed in a 64-pin TQFP (10 x 10 mm) package with an industrial -40C to +85C temperature rating, and provides 16 KB of RAM for data buffering in mixed-signal and connected designs. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (typically flash), volatile data memory (RAM), and a rich set of peripheral IP into one package. The PIC24F sub-family sits within Microchip's 16-bit MCU hierarchy above the 8-bit PIC16/PIC18 and below the dsPIC and 32-bit families, and is engineered for low-power (<100 nA standby current) connected applications. Within that hierarchy the 'GA1' pin-count family adds multiple serial ports, timers, and analog peripherals to the base PIC24F feature set. Key features of the PIC24FJ64GA106-I/PT include: 64 KB flash, 16 KB RAM, up to 32 MHz operation, three I2C and three SPI ports, four UART channels, 23 independent timers, a 16-channel 10-bit ADC, and a charge time measurement unit (CTMU). The CTMU enables capacitive-touch sensing, while the 10-bit ADC supports general analog conversion. These peripherals are exposed across the 64 TQFP pins, giving designers flexibility to map multiple communication buses simultaneously. Architecturally, the device uses a modified Harvard core with a 16-bit instruction word, 24-bit program address space, and a peripheral bus supporting DMA between memory and select peripherals. The XLP core minimizes dynamic power consumption and provides deep-sleep current below 100 nA, while the on-chip RTCC keeps calendar time across sleep states. The internal 8 MHz Fast RC oscillator with PLL can be selected for low BOM designs. Typical applications include low-power consumer and industrial sensor nodes, capacitive touch user interfaces, USB- and UART-connected embedded products, motor control peripherals, and battery-powered data loggers. The multiple UARTs and I2C/SPI buses make the part especially useful as a sensor hub. The 16 KB RAM buffer is large enough for Ethernet or display frame-buffer support when paired with a MAC/PHY or graphic controller. A key design consideration is the 2.5V/3.3V dual supply operation: the core logic runs from an internal regulator fed by VDD, while I/O pads are powered by a separate VDDCORE/VDDIO rail and tolerate up to 5V. Decoupling caps must be placed close to every VDD/VSS pair, and unused I/O must be configured as outputs low to minimize leakage.

The Microchip Technology PIC24FJ64GA110-I/PF is a 16-bit RISC Flash microcontroller from the PIC24F family, delivering 16 MIPS at 32 MHz with 64 KB of program Flash and 16 KB of on-chip data RAM, housed in a 100-pin TQFP (14x14 mm) package. It belongs to the PIC24FJ64GA110 series which targets low-power (<100 nA standby current) and connectivity-rich general-purpose embedded applications, integrating 3x I2C, 3x SPI, 4x UART, and 23 independent timers alongside a 10-bit ADC and parallel master port. Background knowledge - what is a PIC24F microcontroller? The PIC24F is a 16-bit modified-Harvard RISC microcontroller family from Microchip Technology, sitting between the 8-bit PIC16/PIC18 families and the 16-bit dsPIC families in the Microchip portfolio. PIC24F devices use a 16-bit instruction word with 24-bit instruction encoding, deliver up to 16 MIPS performance, and are recognized for eXtreme Low Power (XLP) technology with nanoWatt sleep currents. They target the same role in the system hierarchy as Cortex-M0/M0+ parts from other vendors: low-power, cost-sensitive, connectivity-rich embedded control where an 8-bit core is too constrained but a full Cortex-M3/M4 is overkill. Key features include 64 KB (22K x 24) self-programmable Flash, 16 KB SRAM, a hardware Real-Time Clock and Calendar (RTCC) with calendar mode, a 16-channel 10-bit ADC with 500 ksps conversion rate, and the Peripheral Pin Select (PPS) remapping system that allows flexible assignment of digital peripherals to I/O pins. The device supports 2.0V to 3.6V single-supply operation and offers four power-managed modes: Run, Idle, Sleep with RTCC, and Deep Sleep. The PIC24FJ64GA110 uses a modified-Harvard architecture with separate 24-bit program and 16-bit data paths, hardware multiply/divide, and a 16-element working register array. The PPS subsystem maps digital peripheral functions (UART, SPI, I2C, timer outputs, interrupt inputs) onto selected RPn pins via configuration bits, simplifying PCB routing. The integrated RTCC with timestamp and tamper-detection features is uncommon in this class and reduces external RTC component count. Typical applications include low-power IoT sensor nodes, industrial HMI panels, USB-less consumer devices, motor control reference designs (with companion dsPIC), and connectivity-rich embedded control (UART/SPI/I2C bridges). The combination of 23 timers and four UARTs makes it well suited to multi-protocol gateway applications. The 100-TQFP package exposes all 85 I/O pins, enabling direct bus or parallel-master-port interfaces to external peripherals or external memory. Design consideration - when designing with this device, leverage the Peripheral Pin Select system to optimize PCB layout flexibility, but be aware that PPS remapping is set at runtime and must be re-initialized on every reset. For battery-powered applications, the Deep Sleep mode with RTCC retention provides the lowest quiescent current and is preferable over Idle or Run modes. The 100-TQFP package has a larger footprint than 64-pin variants - choose the 100-pin device only when its 85 I/O pins are genuinely required.

The nanoWatt technology label indicates deep-sleep currents below 100 nA for battery-backed applications. Compared with PIC24FJ128 variants this part uses half the Flash and so is positioned for budget-constrained designs that do not need 128 KB. Architecturally, the PIC24FJ64GA110T-I/PF uses a modified Harvard core with separate program and data buses, a hardware multiply/divide unit, and a peripheral engine capable of running PWM, ADC, and communication blocks independently of the CPU. The 100-TQFP package exposes most pins as GPIO and as alternate-function peripheral mappings, enabling large mixed-signal designs with both analog sensing and digital I/O. Industrial-grade silicon and the 16 MIPS throughput make it suitable for real-time control loops such as BLDC motor commutation, sensor fusion front-ends, and human-interface subsystems. Typical applications include industrial sensor hubs, BLDC and stepper motor control, USB-aware human-interface panels, and low-power remote sensor nodes. Designers also use this family for graphical displays, multi-protocol bridges, and medical/consumer devices that need more than an 8-bit MCU but do not justify a 32-bit part. The tape-and-reel -T suffix indicates factory packaging for SMT assembly lines, and the -I grade supports commercial-to-industrial enclosures.

It integrates 64 KB self-programmable Flash, 8 KB SRAM, multiple timers, UART/SPI/I²C interfaces, a 10/12-bit ADC, and eXtreme Low Power (XLP) sleep modes that drop quiescent current below 1 µA, ideal for battery-powered secure nodes. The device combines a 16-bit modified-Harvard CPU with dedicated crypto peripherals and rich analog/digital peripherals on the same die. This integrated approach reduces BOM count and PCB area compared to discrete MCU plus external crypto IC designs, while preserving the low-power advantages of the PIC24F XLP architecture. Typical applications include IoT secure end nodes, smart sensors with authenticated firmware updates, industrial data loggers with secure storage, medical wearable monitors, and wireless sensor networks. The hardware crypto engine accelerates TLS/DTLS handshakes and secure boot verification on edge devices. When designing with this MCU, ensure VDDCORE decoupling follows the datasheet reference layout - typically a 10 µF bulk plus 0.1 µF ceramic on each VDD pin. The 'T' suffix in the MPN indicates tape-and-reel packaging and the 'I' suffix denotes the -40 °C to +85 °C industrial temperature grade.

The device is part of the 64/80/100-pin general-purpose PIC24F family with integrated LCD controller and ultra-low-power features including a Low-Voltage Sleep mode that maintains state and RAM at a typical current of 340 nA. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a rich set of peripherals such as timers, communication interfaces, and analog blocks. Within the broader taxonomy, the PIC24FJ64GA306 sits in the 16-bit MCU category - between 8-bit PIC16/PIC18 parts and 32-bit PIC32 parts - and within Microchip's hierarchy it belongs to the PIC24F XLP family of low-power microcontrollers. This positioning gives designers a balance of deterministic 16-bit performance and battery-friendly sleep current. Key features include 64 KB Flash organized as 22K x 24 words, 8 KB RAM, up to 53 general-purpose I/O pins, six DMA channels for offloading the CPU, and up to 16 channels of 12-bit A/D conversion with 10-bit A/D option. Connectivity peripherals cover I2C, SPI, UART/USART, IrDA and LIN, while dedicated peripherals include Brown-out Detect/Reset, POR, PWM, WDT, LCD controller, and RTCC with VBAT backup. The 32 MHz oscillator drives the 16 MIPS pipeline; operation spans 2.0 V to 3.6 V across the -40C to +85C industrial temperature range. Architecturally, the device uses a modified Harvard core with separate program and data paths, allowing concurrent fetch and access. XLP technology combines multiple power management modes (Sleep, Deep Sleep, Low-Voltage Sleep with RTCC) and a fast wake-up from 1.6 us to deliver nano-amp sleep currents with active-mode run currents in the mA range, enabling years of battery life on coin cells or two-AA packs. Typical applications include industrial HMI panels with segment-LCD displays, medical monitoring devices, energy metering, battery-powered sensor nodes, home appliances with LCD user interfaces, and automotive body/comfort modules. The integrated LCD controller removes the need for an external driver for segment displays up to a few hundred segments. Designers should note that the 'I' suffix denotes the industrial -40C to +85C temperature grade and the 'PT' suffix denotes the 64-pin TQFP package. When migrating within the PIC24FJ64GA3xx family, pinout is shared across -64-, -80- and -100-pin variants of the same die, enabling easy PCB re-spins with the same firmware.

The Microchip Technology PIC24FJ64GA306T-I/MR is a 16-bit microcontroller from the PIC24F XLP family featuring 64 KB (22K x 24) of Flash program memory and 8 KB of RAM, integrated into a 64-pin VQFN (9x9 mm) package with 85 configurable I/O pins. It executes up to 16 MIPS at 32 MHz from a 2.0V to 3.6V supply, leveraging a modified Harvard architecture for deterministic single-cycle instruction execution and deterministic interrupt latency. A 16-bit microcontroller is a single-chip computer that uses an internal data path 16 bits wide, enabling more efficient arithmetic on larger integers and richer peripheral addressing than 8-bit cores while retaining low power consumption. PIC24F microcontrollers sit within the broader hierarchy of microcontroller -> embedded controller -> semiconductor; the FJ sub-family adds nanoWatt XLP technology and integrated LCD driver support, positioning this device for low-power human-machine interface designs. Key features include nanoWatt XLP technology with a Low Voltage Sleep current of approximately 340 nA that retains RAM and core state, a real-time clock and calendar (RTCC) module, a 10-bit ADC capable of up to 500 ksps, multiple UART/SPI/I2C peripherals, and a dedicated LCD segment driver interface. The CTMU charge-time measurement unit enables touch sensing and capacitance measurement, while a 16-bit parallel master port and EPMP support external bus expansion for graphics or memory. Architecturally, the PIC24FJ64GA306T-I/MR pairs a wide 16-bit ALU with a 24-bit instruction word to balance code density and execution speed. The integrated voltage regulator supports operation down to 2.0V, and the peripheral pin select (PPS) feature allows digital peripheral I/O to be remapped to most general-purpose pins, simplifying PCB routing. Hardware crypto and unique MAC address support are absent on this part; cryptographic options are addressed by separate PIC24Fxx and dsPIC33 families. Typical applications include battery-powered IoT sensor nodes, portable medical monitors, smart metering with LCD readouts, industrial HMI panels, USB peripherals using an external transceiver, and low-power remote controls. The wide operating temperature range of -40C to +85C makes the device suitable for industrial and outdoor installations. When designing with this device, ensure that Vcap decoupling is provided per datasheet recommendations and that unused I/O pins are configured as outputs to minimize transient current. PPS configuration should be locked early in initialization to prevent bus contention during bootstrap.

A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory (typically flash), volatile data memory (RAM), and a rich set of on-chip peripherals such as timers, ADCs, communication interfaces, and I/O. The PIC24F family is Microchip's 16-bit Modified Harvard architecture line, positioned between the 8-bit PIC16/PIC18 families and the 32-bit PIC32MX/DA families, and is widely used in consumer, industrial, and battery-powered embedded applications. The "FJ" suffix denotes the flash-based, nanoWatt XLP ultra-low-power variant family. Key features include 64KB (22K x 24 instructions) self-programmable flash, 8KB SRAM, an integrated 10-bit/12-bit ADC (per LCSC description), up to 16 channels of ADC input, multiple serial interfaces (I2C, IrDA, LINbus, SPI, UART/USART), a segmented LCD controller supporting up to 480 segments, and peripherals including DMA, PWM, brown-out detect/reset, watchdog timer, and POR. The nanoWatt XLP technology offers multiple power-saving modes and a low-voltage Sleep mode retaining RAM at roughly 340 nA. The device uses Microchip's PIC24F core with a 16-bit wide datapath and 24-bit instruction word, supporting C and assembly development under MPLAB X IDE and the MPLAB XC16 compiler. The architecture features deterministic interrupt latency, a hardware multiply/divide engine, and rich DMA capability, making it suitable for real-time control loops and event-driven firmware. The segmented LCD controller can directly drive glass displays without external driver ICs in many configurations. Typical applications include battery-powered portable products, IoT edge sensor nodes, industrial metering with LCD readouts (gas/water/heat meters), medical handheld devices, consumer electronics with LCD UI, automotive body and HVAC subsystems, and home appliance control boards with segment displays. The combination of low-power sleep, RTC backup via VBAT, integrated LCD, and ample I/O makes it well suited for mains-and-battery hybrid designs. When designing with this part, ensure that the on-chip voltage regulator's decoupling (a 10 uF bulk capacitor on VDDCORE / AVDD plus 0.1 uF ceramic bypass) is placed close to the package, and verify the trace length on MCLR to avoid in-circuit programming glitches. The wide operating voltage range simplifies both 3.3 V and 5 V mixed designs, and the segmented LCD controller can simplify BOM cost compared to designs that pair an MCU with an external LCD driver.
