PIC24FJ32GB002-I/SP

PIC24FJ32GB002-I/SP - 32KB Flash USB MCU 28-SPDIP | Microchip

The Microchip PIC24FJ32GB002-I/SP is a 16-bit PIC microcontroller from the PIC24F XLP family, integrating Full-Speed USB 2.0 on-chip with 32 KB of Flash program memory and 8 KB of RAM, housed in a 28-pin SPDIP (SP) through-hole package. It runs at up to 32 MHz (16 MIPS) from a 2.0-3.5V supply, making it one of the lowest-power USB-capable 16-bit MCUs in the Microchip portfolio. The part suffix /SP designates the 28-SPDIP industrial temperature range (-40C to +85C). A microcontroller (MCU) is a single-chip computer containing a CPU core, program and data memory, and integrated peripherals. The PIC24F family sits in the 16-bit tier of Microchip's product hierarchy: 8-bit PIC10/12/16 -> 16-bit PIC24F/dsPIC -> 32-bit PIC32. Within PIC24F, the 'J' family is the ultra-low-power XLP variant while 'GB' indicates Full-Speed USB 2.0 device support - a unique combination for battery-powered USB peripherals. Key features include 32 KB self-programmable Flash (11K x 24 words), 8 KB RAM, a 10-bit ADC up to 500 ksps with up to 9 analog channels, three 16-bit timers, two UART modules, two SPI modules, two I2C modules, and a CTMU for capacitive touch sensing. The integrated USB 2.0 Full-Speed (12 Mbps) device controller with an internal transceiver eliminates external USB PHY components, lowering BOM cost for HID, CDC, and custom-class USB devices. The architecture uses a Harvard RISC core with 16-bit instructions and a modified Harvard memory map, achieving 16 MIPS throughput. The nanoWatt XLP technology delivers sleep currents below 50 nA typical, and the part supports multiple low-power modes (Sleep, Idle, Deep Sleep) with multiple clock sources including the on-chip 8 MHz FRC and the 31 kHz LPRC oscillator. Typical applications include USB Human Interface Devices (HIDs) such as keyboards and mice, USB-to-UART bridges, USB data loggers, battery-powered USB medical sensors, and capacitive touch user interfaces. The 28-SPDIP package is favored for hobby, educational, and through-hole prototyping designs where socketed or hand-soldered replacement is desired. When designing with this part, ensure the USB VBUS pin is properly decoupled and that the internal 3.3V regulator is bypassed per datasheet. The 28-SPDIP form factor requires through-hole pads - for SMD designs the SOIC-28 or QFN variants of the same die are available in the family. The integrated USB transceiver reduces code complexity but the firmware stack (Microchip Harmony or MLA) should still be used for enumeration.

PIC24F devices use a 16-bit modified Harvard architecture with single-cycle instruction execution and a 16 x 16 hardware multiplier, occupying the mid-tier of Microchip's 8-bit/16-bit/32-bit microcontroller hierarchy (PIC10/12/16 -> PIC24F/dsPIC -> PIC32). The 'FJ' suffix denotes the Flash-based, low-power variant. Key features include Full-Speed USB 2.0 device support with on-chip transceiver, up to 33 general-purpose I/O pins, a 10-bit ADC with up to 13 input channels, five 16-bit timers (Timer1 plus four Timer2/3/4/5 type modules configurable as pairs), two UART modules, two SPI modules, and two I2C modules. The CTMU (Charge Time Measurement Unit) provides touch sensing and precise time measurement, and the RTCC keeps time in deep sleep modes. The device includes a hardware CRC and a Parallel Master Port on certain package variants. The PIC24FJ32GB004 is built on a CMOS process with nanoWatt XLP technology that delivers sleep currents below 1 uA with RAM retention, suiting battery-powered designs. Its 16-bit core, hardware multiply/divide, and C-optimized instruction set accelerate DSP-style tasks (FIR/IIR filtering, control loops) compared with 8-bit MCUs, while the Full-Speed USB 2.0 integrated transceiver eliminates the external PHY needed by many competing parts, reducing both BOM cost and PCB area in USB peripherals. Typical applications include USB Human Interface Devices (HID) such as keyboards, mice, and game controllers; USB-to-UART bridges; USB data loggers; medical instrumentation with USB connectivity; industrial USB sensor nodes; consumer electronics with USB charging/communication; and low-power IoT edge devices that require sporadic USB-driven updates. The wide 2.0V-3.6V supply range supports direct Li-Ion battery operation. When designing with this device, place the 4.7 kohm pull-up on D+ (or D- for low-speed) per the USB specification, add 100 nF decoupling on each VDD pin and a bulk 4.7-10 uF near the regulator, and ensure the VUSB pin sees 3.3V for the on-chip transceiver. Failure to do so is the most common cause of USB enumeration failures.

PIC24FJ32GP202-E/MV - 32KB Flash, 16-bit XLP MCU | Microchip
PIC24FJ32GP202-E/MV

PIC24FJ32GP202-E/MV - 32KB Flash, 16-bit XLP MCU | Microchip

The Microchip Technology PIC24FJ32GP202-E/MV is a 16-bit PIC24F microcontroller from the GP2/GU2 family featuring 32KB of ECC Flash, 8KB of RAM, and a 32 MHz (16 MIPS) core, housed in a 28-pin UQFN (4x4 mm) MV package with extended (-40C to +125C) temperature range. It integrates core independent peripherals (CIPs) and a Full Speed USB 2.0 Host/Device/OTG controller, with sleep current measured in the hundreds of nA while retaining the complete RAM and interrupt state. What is a PIC24F microcontroller? The PIC24F is Microchip's 16-bit microcontroller family using a modified Harvard RISC architecture with 16 MIPS performance at 32 MHz. It sits above the 8-bit PIC16/PIC18 families in performance and below the dsPIC/PIC32 families. It is widely used in ultra-low-power (XLP) battery applications, mixed-signal designs, and USB-enabled embedded products where 32-bit performance is overkill but 8-bit MCUs lack the throughput or peripherals. Key features include hardware ECC on Flash for greater data integrity, 4 channels of DMA, up to 22 channels of 10/12-bit ADC at 500 ksps, 5 16-bit timers, configurable logic cells (CLC), and multiple serial interfaces (UART, SPI, I2C). The integrated USB 2.0 FS OTG controller with on-chip transceiver eliminates the need for external PHY chips, significantly shrinking the BOM for low-power USB devices. Architecturally, the PIC24FJ32GP202 uses a 16-bit modified Harvard core with a 24-bit instruction word for compact code density. The CIPs (configurable logic cells, comparators, PWM, RTCC, etc.) operate independently of the CPU, allowing events such as ADC-triggered conversions and PWM-shutdown on comparator faults without CPU wake-up - a key reason the XLP sleep current stays in the nanoamp range. Typical applications include USB HID peripherals, IoT sensor nodes, e-metering, low-power medical wearables, consumer battery chargers, and industrial control with USB diagnostic interfaces. The extended -40C to +125C temperature range (the 'E' suffix) makes it suitable for automotive under-hood and outdoor industrial deployments. When designing, ensure VDD decoupling uses a 100 nF ceramic placed within 2 mm of the VDD pin and a 10 uF bulk on the main rail. The UQFN-28 exposed pad must be soldered to the PCB ground plane for proper thermal dissipation and electrical ground reference - missing this connection causes erratic USB operation.

The device integrates two I2C, two SPI, two UART peripherals, six timers, two DMA controllers, multiple analog comparators, configurable logic cells (CLC), and a USB 2.0 Full-Speed Host/Device/OTG controller on-chip. An MCU (Microcontroller Unit) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and configurable peripherals. Within the PIC24F family, the 'GP2' sub-family targets general-purpose ultra-low-power designs with embedded USB, while the 'GU2' sub-family adds additional features. PIC24FJ devices sit in Microchip's hierarchy as: 16-bit MCU -> PIC24 -> PIC24F -> eXtreme Low-Power (XLP) family -> power-efficient embedded controllers for sensor, HMI and USB edge-node applications. Key features of this part include ECC Flash for enhanced program-memory reliability, XLP (eXtreme Low-Power) technology with sleep currents down to a few hundred nanoamps while retaining SRAM and peripheral state, an on-chip 32 kHz low-power oscillator, and a 10-bit 1.1 Msps ADC. Five flexible package options (28-pin SSOP/SOIC/QFN, 44-pin QFN/TQFP) allow board-level scaling across product variants. Architecturally, the PIC24FJ32GP202 uses a 16-bit modified Harvard RISC core with hardware multiply/divide, a 24-bit instruction word, and a peripheral pin-select (PPS) system that lets most digital peripherals be remapped to a wide range of I/O pins. This PPS flexibility simplifies PCB routing when several I2C, SPI or UART channels must be distributed across the 28-pin SSOP footprint. Typical applications include USB peripherals (HID, CDC, MSD), portable medical and fitness sensors, low-power wireless sensor nodes, e-metering and home-automation gateways, and battery-powered industrial data loggers. The combination of USB-OTG, ECC Flash and XLP makes the device a frequent choice for edge nodes that must reliably store firmware while spending most of their lifetime in deep sleep. When designing with this MCU, ensure the USB bus pins (D+, D-) are routed as a 90-ohm differential pair, that the VUSB pin is supplied from VDD or the internal USB regulator per the datasheet, and that the Vcap decoupling capacitor follows the recommended value to stabilize the core logic voltage domain.

PIC24FJ32GP202T-I/SO - 16-bit 32MHz 32KB Flash MCU w/ USB | Microchip

The Microchip Technology PIC24FJ32GP202T-I/SO is a 16-bit PIC24F microcontroller featuring a 32MHz CPU core, 32KB of ECC Flash program memory and 8KB of RAM, housed in a 28-pin SOIC package with industrial-grade -40C to +85C operating range. The 'T' suffix indicates tape-and-reel packaging for high-volume assembly lines, and the part integrates Full-Speed USB 2.0 Host/Device/OTG alongside several core-independent peripherals (CIPs) including Real-Time Clock, CRC, and PMP. The supply voltage range is 2.0V to 3.6V with a nominal 3.3V rail typical of the PIC24F XLP (eXtreme Low Power) family, and sleep currents are documented in the low hundreds of nA with full RAM/CPU retention. A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory (Flash/ROM), data memory (RAM), and a rich set of peripherals (timers, ADC, communication blocks, I/O) on a single die. The 16-bit class sits between 8-bit AVR/PIC-MCU parts and 32-bit ARM Cortex-M devices, offering a balance of code density, deterministic interrupt latency, and richer peripheral integration than 8-bit cores. PIC24F parts in particular target low-power, mixed-signal, USB-equipped embedded designs where 32-bit performance is not required.

The 28-SOIC package suits hand-soldered prototypes and through-hole-style manufacturing flows while still offering all peripheral capability of the larger pin-count siblings. Architecture-wise, the part uses a modified Harvard bus with separate instruction and data paths, a 16-element register file, and CIP blocks that operate independently of the CPU. The XLP technology achieves deep-sleep retention modes drawing only a few hundred nanoamps while preserving RAM and interrupt context, enabling coin-cell or energy-harvesting powered designs. Typical applications include USB HID/CDC peripherals (keyboards, custom sensors, debug probes), low-power IoT sensor nodes, USB battery chargers, and industrial data-loggers.

A 16-bit microcontroller (MCU) is an embedded processor with a 16-bit data path, register file, and ALU, positioned between 8-bit entry-level MCUs and 32-bit Cortex-M class devices. The PIC24FJ family extends Microchip's 16-bit dsPIC/PIC24 line with XLP nanoWatt technology and dedicated USB-OTG silicon, targeting battery-powered and tethered peripherals that demand deterministic interrupt response, hardware CIPs for offloading the CPU, and USB connectivity in a single die. Key differentiating specifications include integrated Full-Speed USB 2.0 Host/Device/OTG, 32 KB ECC Flash with hardware error correction for improved reliability in harsh environments, 8 KB RAM that supports USB endpoint buffers plus application stack/heap, and XLP sleep currents in the hundreds of nanoamperes while retaining SRAM and interrupt context. The 16 MIPS performance at 32 MHz gives 62.5 ns instruction cycle, suitable for real-time control loops. Peripherals typically include multiple UART/SPI/I2C, a 10/12-bit ADC, comparators, and RTCC. Typical applications are USB Human Interface Devices (HID), USB-to-UART bridges, low-power sensor loggers, industrial data loggers with USB upload, medical point-of-care USB peripherals, and battery-powered consumer accessories. The 28-SOIC footprint eases hand-soldering and rework for prototypes and small-volume production. When designing, allocate the 8 KB RAM carefully between USB endpoint FIFOs and application data to avoid overrun, place the USB DP/DM traces as a 90-ohm differential pair, and bypass VDD/VUSB with 100 nF plus 4.7 µF bulk capacitors placed within 5 mm of the pins.

PIC24FJ32GU202-E/SS - 16-Bit 32MHz USB MCU, 32KB Flash | Microchip
PIC24FJ32GU202-E/SS

PIC24FJ32GU202-E/SS - 16-Bit 32MHz USB MCU, 32KB Flash | Microchip

The Microchip Technology PIC24FJ32GU202-E/SS is a 16-bit microcontroller from the PIC24FJ GP2/GU2 family that integrates Full-Speed USB 2.0 Host/Device/OTG, 32KB of ECC Flash program memory (11K x 24 words), and 8KB of RAM in a 28-pin SSOP package. It executes up to 16 MIPS at a 32 MHz CPU clock and is targeted at low-power embedded designs with sleep currents down to a few hundred nanoamperes, retaining the complete SRAM and configuration state. The PIC24FJ family sits at the intersection of the 16-bit microcontroller class and the wider 8/16/32-bit MCU hierarchy. PIC microcontrollers (Peripheral Interface Controllers) are Harvard-architecture RISC devices originally introduced by Microchip in 1975. The 16-bit PIC24F sub-family targets low-power (XLP) applications and adds a modified Harvard bus, a 16-bit data path, and DSP-friendly instructions while staying within a 2V to 3.6V supply envelope. This particular part adds an integrated USB 2.0 Full-Speed transceiver, eliminating the need for an external PHY on USB-equipped designs. Key features include Core Independent Peripherals (CIPs) such as configurable logic cells, multiple capture/compare/PWM modules, a 10/12-bit ADC, and a hardware RTCC. The 32 KB ECC Flash improves reliability in harsh environments, while 8 KB of RAM supports modest buffering for USB and sensor pipelines. The device also offers multiple sleep modes (deep sleep, retention, and idle) with a few-hundred-nA typical sleep current. Architecturally, the PIC24FJ32GU202 uses Microchip's modified Harvard design with separate program and data buses, a 16-bit instruction word, and a 32 MHz maximum internal oscillator. The integrated USB module supports Host, Device, and On-The-Go roles, and the on-chip 1.5 kB USB endpoint RAM covers typical CDC/HID/MSD classes. Core Independent Peripherals operate without CPU intervention, allowing the core to remain in sleep and reducing overall system power. Typical applications include USB HID peripherals, USB-to-UART bridges, low-power sensor hubs, consumer medical data loggers, battery-powered IoT edge nodes, and embedded human-interface devices. Designers can also use the on-chip USB and the 8 KB RAM to implement small mass-storage or CDC virtual COM-port functions. The wide 2V to 3.6V operating range makes the part suitable for single-cell Li-ion powered hardware. A key design consideration is the 28-pin SSOP package: only 20 of the 28 pins are user I/O, so high-pin-count peripherals are limited; multiplexing with the integrated USB signals is essential. The E temperature grade extends operating range from -40C to +125C, suiting industrial and outdoor deployments. For prototyping, the MPLAB X IDE and the XC16 compiler form a complete toolchain, with the PICkit or ICD programming/debugging probes supporting on-board flash programming.

PIC24FJ32GU202-I/ML

PIC24FJ32GU202-I/ML - 16-bit USB MCU 32KB Flash 28-QFN | Microchip

The Microchip Technology PIC24FJ32GU202-I/ML is a 16-bit PIC microcontroller from the PIC24FJ GP2/GU2 family, featuring a 32 MHz MIPS core, 32 KB of ECC Flash program memory (11K x 24 words), 8 KB of RAM, and an integrated Full-Speed USB 2.0 Host/Device/OTG controller, all housed in a 28-pin QFN (6x6 mm) surface-mount package. According to the Microchip product page, the device operates from 2.0V to 3.6V and supports sleep currents down to a few hundred nanoamps while retaining complete SRAM and RTCC operation, making it a member of the eXtreme Low-Power (XLP) family. A 16-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/RAM), and peripherals on one silicon die. PIC24F devices use a 16-bit modified Harvard RISC architecture with a 24-bit instruction word, sitting in the hierarchy between 8-bit PIC16/PIC18 MCUs and 32-bit PIC32MX/ARM Cortex-M parts. The PIC24FJ32GU202 belongs to the broader category of embedded microcontrollers, which are the foundational building blocks of modern electronic systems, responsible for executing firmware that controls sensors, communication interfaces, displays, and actuators. The PIC24FJ32GU202 integrates several features that differentiate it within the PIC24FJ family: an integrated USB 2.0 Full-Speed transceiver supporting Host, Device, and OTG roles (a rare combination at this pin count), four 16-bit timers, a 10-bit ADC with up to 9 channels, multiple serial interfaces (UART, SPI, I2C), and a chargeable RTCC. Its eXLP (Extreme Low Power) design includes multiple low-power operating modes, deep sleep with RTCC retention drawing only hundreds of nA, and a peripherals-only mode that keeps CIPs running while the CPU sleeps. Typical applications include USB peripherals (HID, CDC, MSD class devices), wearable health and fitness sensors, battery-powered IoT end nodes with USB charging, low-power sensor hubs, industrial data loggers, and consumer devices that need a single MCU to handle both USB connectivity and low standby power. The 28-QFN package provides 20 usable I/O pins and is footprint-compatible with other PIC24FJ32GU2-series parts, allowing easy migration between memory sizes within the family. When designing with this part, plan for the integrated USB PHY's 48 MHz clock requirement: either use the internal PLL with an external 8 MHz crystal, or provide an external 48 MHz source. The CIPs (Core Independent Peripherals) such as the 16-bit PWM and configurable logic cells can offload tasks from the CPU, reducing firmware complexity and active time. Vcap pin decoupling per datasheet recommendations is required for core regulator stability.
