PIC24FJ128GU406-I/MR - 16-Bit 32MHz 128KB Flash MCU | Microchip

The Microchip Technology PIC24FJ128GU406-I/MR is a 16-bit microcontroller from the PIC24F eXtreme Low-Power 'GU4' family, featuring 128KB of Flash program memory, 32KB RAM, and a 64-pin QFN (9x9mm) package. It runs at up to 32MHz (16 MIPS) with a 2V to 3.6V supply range and is built around the PIC® 24F modified Harvard RISC architecture. What is a 16-bit microcontroller? A microcontroller (MCU) is a single-chip computer containing a CPU core, memory (Flash/RAM), peripherals, and I/O. 16-bit MCUs like the PIC24F balance higher computational throughput than 8-bit parts (e.g. PIC16) with lower cost and power than 32-bit MCUs (e.g. PIC32, ARM Cortex-M). Within Microchip's taxonomy, PIC24FJ belongs to the eXtreme Low-Power family (F-core), which emphasizes low active and sleep current consumption for battery-powered and always-on applications. Key features include dual-partition Flash supporting real-time Over-The-Air (OTA) firmware updates with EEPROM emulation, a segment LCD controller with up to 60 segments, a full-speed USB 2.0 full-speed (12 Mbps) device/host/OTG transceiver, and 53 digital I/O pins. The device also integrates multiple Core Independent Peripherals (CIPs) such as Configurable Logic Cells (CLC), Multiple Output Capture/Compare/PWM (MCCP/SCCP), 32-bit timers, a 12-bit 200 ksps ADC, and multiple UART/SPI/I2C interfaces that offload tasks from the CPU. The architecture uses a 16-bit modified Harvard bus, hardware Multiply/Divide for DSP-style operations, and an 8-deep programmable software stack. Wide on-chip peripherals let the device perform sensor fusion, LCD driving, USB communication, and OTA firmware updates without external logic, reducing BOM cost and PCB area in space-constrained designs. Typical applications include IoT sensor nodes with USB-C charging and OTA updates, low-power medical devices with LCD displays (glucose meters, infusion pumps), industrial HMI panels with segmented LCDs, USB human-interface devices (HID) such as keyboards and mice, e-metering / smart utility metering, and portable consumer electronics with always-on displays. When designing with this device, plan the dual-partition Flash carefully: the two partitions allow safe OTA updates by writing to the inactive partition, then atomically switching the boot pointer. For LCD designs, allocate sufficient bias resistor network and consider eXtreme Low-Power sleep modes (Deep Sleep, Sleep, Idle) to extend battery life to microamp-level standby currents.

The PIC24FJ16GA002 targets low-power, mixed-signal embedded applications where deterministic response, small footprint, and extended temperature are required. Key features of this part include 16 KB self-programmable Flash with 10K erase/write cycles, 4 KB SRAM, an internal 8 MHz FRC oscillator with 4x PLL to 32 MHz, a 5-channel DMA controller, and CTMU support for capacitive touch. The on-chip 3.3V LDO powers the core from a 2.0-3.6V supply, eliminating external regulation. Five 16-bit timers (Timer1-Timer5) provide capture, compare, and PWM capability for motor and lighting control. The architecture is built on an enhanced 16-bit CPU core with 24-bit instruction words and two address spaces (program/data), enabling C-compiler optimization. The 10-bit ADC with 13 effective channels and the Peripheral Pin Select (PPS) remapping allow flexible signal routing without board rework. Together these give the PIC24FJ16GA002 a strong analog/digital balance for sensing and control. Typical applications include LED lighting controllers, industrial sensor nodes, home automation, low-power IoT battery devices, HVAC controls, and automotive interior modules. The wide operating voltage and built-in touch support make it popular in user-interface and human-machine interface designs. When designing with this MCU, place a 0.1 uF decoupling capacitor adjacent to each VDD/VSS pair and route analog/digital grounds to a single point. Use Peripheral Pin Select carefully, as remapped functions still share priority and conflict resolution logic. Programming is supported by MPLAB X IDE, XC16 compiler, and PICkit ICD tools. This page consolidates distributor pricing, drop-in alternatives, and design notes synthesized from the manufacturer datasheet and application notes, providing practical engineering context beyond the factory datasheet alone.

PIC24FJ16GA002-I/ML

PIC24FJ16GA002-I/ML - 16KB Flash 16-bit MCU 28-QFN | Microchip

The Microchip Technology PIC24FJ16GA002-I/ML is a 16-bit PIC24F microcontroller with 16 KB of Flash program memory, 4 KB of RAM, and 21 I/O pins, housed in a 28-pin QFN (ML) package rated for industrial -40C to +85C operation. It delivers up to 16 MIPS performance from a 32 MHz CPU clock, features a modified Harvard architecture with a 17-bit x 17-bit single-cycle hardware multiplier, and integrates an 8 MHz internal oscillator with 4x PLL and multiple divide options for flexible clocking. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, I/O peripherals, and interrupt logic onto one die. The PIC24F family specifically uses Microchip's 16-bit enhanced RISC architecture and is positioned in the mid-range performance tier between 8-bit PIC MCUs and 32-bit PIC32 devices. Within Microchip's hierarchy, this part sits in the PIC24F eXtreme Low Power sub-family, which targets battery-powered and energy-sensitive embedded designs where dynamic power consumption must be minimized without sacrificing compute throughput. Key features include the eXtreme Low Power (XLP) sleep modes that draw nano-amp-level currents, a 16-channel 10-bit ADC with 500 ksps conversion rate, multiple serial interfaces (UART, SPI, I2C), and four 16-bit timers. The device also supports ICSP (In-Circuit Serial Programming) and JTAG boundary scan for development and manufacturing programming workflows. The 28-QFN package provides a compact 6 mm x 6 mm footprint suitable for space-constrained PCB designs. The architecture uses a 24-bit instruction word with 16-bit data path, allowing most instructions to execute in one cycle. The hardware multiply/divide unit accelerates DSP-style computations (filtering, FFT, motor control loops) that would otherwise burden software loops, and the peripheral pin select (PPS) feature lets most digital peripherals be remapped to alternate I/O pins, simplifying PCB routing. Typical applications include industrial sensor interfaces, low-power IoT edge devices, USB human-interface device (HID) controllers, battery-powered data loggers, and consumer white goods. The combination of XLP sleep, integrated ADC, and 16 MIPS throughput makes it well-suited for portable instrumentation that must wake periodically, sample, process, and return to deep sleep. Design consideration: at 32 MHz with 3.3V supply the core draws roughly 15 mA active and 20 nA in deep sleep, so duty-cycling the CPU is the most effective power-reduction lever. Use the internal 8 MHz oscillator with PLL to keep BOM cost low, but add an external crystal when USB or CAN timing accuracy is required.

The 16-bit-wide instruction word (24-bit instructions in PIC24) accelerates C-compiler-generated code, and the instruction set is C-compiler optimized. The peripheral set is mapped via a Peripheral Pin Select (PPS) system on most pins, providing routing flexibility for serial interfaces. Typical applications include LED lighting controllers, capacitive-touch user interfaces, low-power sensor nodes, USB-to-UART bridges, and battery-powered industrial monitors. The combination of XLP sleep current and 16 MIPS throughput makes the PIC24FJ16GA002 a popular choice for designs where the part sleeps most of the time and wakes briefly to process data. When designing with this MCU, select a 2.5 V or 3.3 V LDO for the rail (a typical 100 mA rail is sufficient), place a 100 nF decoupling capacitor on every VDD pin plus bulk 10 uF near the IC, and use the PPS system to remap peripherals if your chosen I/O pins clash with default assignments. Programming is via ICSP using a PICkit or MPLAB programmer; firmware can be developed in MPLAB X IDE with the XC16 compiler.

A 16-bit microcontroller (MCU) is a single-chip processor that fetches and executes 16-bit wide instructions, giving roughly 2-4x the code density and arithmetic throughput of legacy 8-bit microcontrollers while remaining simpler than 32-bit ARM Cortex-M parts. Within the broader taxonomy, the PIC24FJ16GA002 belongs to the PIC24F family (16-bit) -> PIC microcontrollers -> microcontrollers -> integrated circuits -> semiconductors. The 'FJ' suffix indicates the eXtreme Low Power (XLP) variant with nanoWatt technology, while 'GA002' identifies the general-purpose analog variant with USB-free peripherals.

Code-guard security and ICSP/In-Circuit Serial Programming are supported, and the device runs the MPLAB X IDE / XC16 toolchain. Applications include industrial sensing and control modules, low-power consumer devices, sensor hubs, simple USB-less human-interface designs (keypads, displays, motor control loops), and educational / hobbyist platforms where through-hole SPDIP is preferred for breadboarding and rework. The device is also AEC-Q100 qualified in the automotive equivalent (PIC24FJ16GA002-E/SP), making it attractive for non-safety automotive subsystems such as body controllers and lighting. A practical design consideration is the 2.0V-3.6V VDD range: 5V-tolerant I/O is NOT present, so level shifting is required if the design mixes 3.3V logic with 5V sensors or drivers. For new designs, prefer the smaller-footprint SOIC/SSOP/QFN variants (PIC24FJ16GA002-I/SO, -I/SS, -I/ML) when PCB real estate matters; the SPDIP is mainly chosen for prototyping and through-hole legacy boards.

The device operates from 2.0 V to 3.6 V, supports an internal 8 MHz oscillator with 4x PLL, and includes a 17-bit single-cycle hardware multiplier plus a 32-bit by 16-bit hardware divider that accelerate DSP-class routines in C. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, volatile data memory, and a rich set of peripherals (timers, ADC, communication controllers, GPIO). The PIC24F sits in Microchip's 16-bit MCU portfolio between 8-bit PIC16/PIC18 devices and 32-bit PIC32 devices, optimized for low power and deterministic interrupt response. nanoWatt technology adds multiple power-saving modes that are particularly useful in battery-powered and always-on sensor applications. Key features of the PIC24FJ16GA004-E/PT include 35 I/O pins, automotive AEC-Q100 grade 1 qualification for the -E temperature range (-40 °C to +125 °C), a 10-bit ADC with multiple channels, and a modified Harvard architecture with 16-bit instructions and 24-bit address space. The C-compiler-optimized instruction set reduces code size compared to legacy 16-bit cores and supports seamless migration within the PIC24F family. The PIC24FJ16GA004-E/PT architecture uses a modified Harvard bus with separate program and data paths, allowing simultaneous fetch and operand access. The 16-level deep hardware stack, deterministic interrupt response, and peripheral pin-select function enable flexible mixed-signal designs. Internal FRC oscillator trimming combined with PLL multiplication yields stable 32 MHz operation without an external crystal, BOM-reducing for cost-sensitive embedded designs. Typical applications include automotive body and chassis ECUs, industrial sensor interface modules, low-power IoT edge nodes, consumer appliance controllers, USB device peripherals, and portable medical instrumentation. The 16 KB Flash footprint targets applications that need more headroom than an 8-bit MCU but where a 32-bit part would be over-specified. When designing with this part, note that -E suffix denotes the extended temperature grade (-40 °C to +125 °C), which AEC-Q100 qualifies for automotive use. Designers should also evaluate power-budget vs MIPS requirements: at 32 MHz the part delivers 16 MIPS, but switching to 8 MHz FRC plus idle modes can drop nanoWatt sleep current to single-digit microamps. This page consolidates distributor pricing, drop-in same-family alternatives from the PIC24FJ family, and practical design notes that go beyond the manufacturer datasheet.
