It supports real-time Over-The-Air (OTA) updates via Dual Partition Flash with EEPROM Emulation, making it suitable for in-field firmware servicing. A 16-bit microcontroller (MCU) is a programmable semiconductor device that executes instructions on a 16-bit data path, sitting in the hierarchy between 8-bit MCUs and 32-bit ARM Cortex-M parts. PIC24F devices use a modified Harvard architecture with a 16-bit instruction word, 24-bit instruction set encoding, and a 16 MIPS core designed for low-power embedded applications with rich peripheral integration. Within the broader taxonomy, the PIC24FJ falls under microcontroller -> embedded MCU -> semiconductor IC. Key features of the PIC24FJ256GU408 include 256 KB ECC Flash (single partition option) with 32 KB RAM, hardware crypto support on selected variants, a full-speed USB 2.0 device/host/OTG controller, an integrated LCD driver (up to 64 segments x 4 commons), a 12-bit ADC, multiple UART/SPI/I2C peripherals, and Core Independent Peripherals (CIPs) such as CLC, MCCP, and DMA. The 80-TQFP package provides ample I/O with 69 remappable I/O pins. Architecturally, the part uses Microchip's nanoWatt XLP eXtreme Low-Power technology, supporting sleep currents below 1 µA in deep sleep with full RAM retention and multiple wake-up sources. The dual-partition flash arrangement allows one partition to run while the other is updated, enabling safe OTA upgrades. Typical applications include USB peripherals (HID, CDC, mass storage), industrial HMI with LCD, medical point-of-care devices, IoT sensor hubs with USB diagnostics, automotive body/comfort modules, and consumer appliances with segmented LCD UI. The integrated LCD and USB eliminate the need for external display drivers or interface chips. When designing, consider that the 80-TQFP requires a 12x12 mm PCB footprint with thermal pad handling and that the dual-partition OTA bootloader requires firmware design considerations for safe rollback. Choose the QFP part for hand-reworkable prototypes, and the QFN/BGA equivalents for space-constrained production.

PIC24FJ32GA002-I/SP

PIC24FJ32GA002-I/SP - 16-bit 32KB Flash MCU 28-SPDIP | Microchip

The Microchip Technology PIC24FJ32GA002-I/SP is a 16-bit PIC24F general-purpose flash microcontroller delivering 16 MIPS performance at 32 MHz, integrating 32 KB of self-programmable Flash program memory and 8 KB of SRAM in a 28-pin SPDIP (Skinny Plastic DIP) through-hole package. The die combines a modified Harvard architecture with a 17-bit x 17-bit single-cycle hardware multiplier and a 32-bit x 16-bit hardware divider, and it includes a 16-channel, 10-bit ADC capable of 500 ksps, two I2C, two SPI, and two UART peripherals plus five 16-bit timers. What is a PIC24F microcontroller? The PIC24F is Microchip's lowest-power 16-bit MCU family built on a modified Harvard architecture: program and data buses are physically separate (16-bit wide for instructions, 8 or 16-bit for data) which lets the CPU fetch an instruction and read/write a data operand in the same cycle, sustaining up to 16 MIPS at 32 MHz while a simpler von-Neumann core would stall. The 'F' suffix indicates on-chip Flash memory and the 'J' indicates the nanoWatt technology extensions used for low-power sleep and idle modes. PIC24F devices sit in Microchip's portfolio between the 8-bit PIC18 and the 32-bit PIC32, offering a C-friendly instruction set, mature toolchains (MPLAB X, XC16), and pin compatibility with many PIC18/dsPIC30 footprints for easy migration. Key features of the PIC24FJ32GA002-I/SP include 21 general-purpose I/O pins, a 2.0 V to 3.6 V single-supply operating range, an on-chip 8 MHz internal oscillator with 4x PLL and multiple postscaler options, 5 PWM channels with 16-bit resolution, two analog comparators, and a real-time clock/calendar with RTCC alarm. The CTMU (Charge Time Measurement Unit) enables capacitive touch sensing and precise time measurements, and the Parallel Master Port (PMP) supports external graphics or bus peripherals. The PIC24FJ32GA002 belongs to the PIC24FJ64GA004 family, sharing a uniform register map and peripheral set with the 64 KB Flash sister parts, so firmware written for one device generally ports to another with a single compiler switch. Program memory is organized as 11K x 24 instruction words, executed from Flash with no external memory interface required. The C-compiler-optimized instruction set, hardware stack, and 16 working registers keep interrupt latency deterministic at 5-6 cycles. Typical applications include low-power industrial sensor nodes, USB/HID human-interface devices (paired with the on-chip UART and a USB-serial bridge), capacitive touch keypads (using CTMU), battery-powered metering, and general-purpose 16-bit embedded control. The wide -40C to +125C operating temperature range also suits it to industrial and certain automotive chassis applications. A key design consideration: at 2.0 V minimum VDD, brown-out and power-on reset thresholds must be respected, and any analog reference for the ADC should be bypassed with at least 0.1 uF plus 10 uF bulk capacitance placed within 5 mm of the AVDD pin.

Typical applications include low-power USB peripherals, sensor data loggers, handheld consumer devices, and industrial control nodes where USB connectivity and battery life are both critical. A primary design consideration is supplying the part from a clean 3.3 V rail within the 2.0 V to 3.6 V window; the internal 1.8 V LDO requires an external bulk capacitor on Vcap. Decoupling 100 nF ceramics near every VDD/VSS pair is mandatory per Microchip reference designs.

The Microchip Technology PIC24FJ32GA104T-I/ML is a 16-bit microcontroller from the PIC® XLP™ 24F family featuring 32KB Flash program memory and 8KB RAM, operating at up to 32 MHz (16 MIPS) in a 44-pin QFN (8x8 mm) package with exposed pad. It integrates a nanoWatt XLP power-management architecture designed for ultra-low-power applications requiring extended battery life. A 16-bit microcontroller (MCU) is a microprocessor that processes data and instructions 16 bits at a time, sitting between 8-bit MCUs and 32-bit MCUs in the embedded hierarchy. 16-bit -> microcontroller -> embedded processor -> semiconductor. The PIC24FJ family specifically targets low-power, mixed-signal applications where 8-bit MCUs lack the throughput but 32-bit MCUs over-consume power, making PIC24F parts a sweet spot for portable medical, sensor, and human-interface designs. Key features include 32 KB Flash (11K x 24 organization), 8 KB SRAM, hardware 16x16 multiply and 32/16 divide in single-cycle execution, and a C-compiler-optimized instruction set. Peripherals span up to 5 timers, 3 UART, 3 SPI, 2 I2C, 10-bit ADC up to 500 ksps with up to 13 input channels, and a Real-Time Clock Calendar (RTCC). The nanoWatt XLP modes offer deep sleep currents below 1 µA (per datasheet characterization), enabling years of operation from coin-cell or lithium batteries. Architecturally, the device uses a modified Harvard bus with separate program and data paths, supporting linear program memory up to 32 KB and linear data memory up to 8 KB. Five I/O ports (RA/RB/RC/RD/RG) provide up to 35 digital I/O pins with individual bit-manipulation control via Peripheral Pin Select (PPS). The 2.5V-3.6V single-supply range and -40°C to +85°C industrial temperature support enable deployment in consumer, industrial, and portable medical end products. Typical applications include handheld medical instruments (glucometers, pulse oximeters), IoT sensor nodes, home automation controllers, HVAC thermostats, and consumer electronics with graphical LCD or capacitive touch interfaces. The PIC24FJ32GA104 family also serves as a low-power companion MCU in multi-processor designs where a higher-performance host offloads always-on sensor and housekeeping tasks. When designing with this MCU, allocate the PPS mapping carefully because each peripheral signal can be routed to one of several pins; conflicts between UART, SPI, and I2C assignments must be resolved at compile time. The QFN-44 package benefits from a central thermal pad that should be soldered to a ground pour for both electrical ground and thermal dissipation. This page synthesizes distributor pricing, drop-in same-package alternatives from the PIC24FJ family, and practical design notes that complement - but do not replace - the manufacturer datasheet.

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.

PIC24FJ32GB002T-I/SS

PIC24FJ32GB002T-I/SS - 16-bit 32KB Flash MCU w/USB OTG | Microchip

The Microchip Technology PIC24FJ32GB002T-I/SS is a 16-bit microcontroller from the PIC® XLP™ 24F family, featuring a 32 MHz core, 32 KB of Flash program memory (organized 11K x 24), and 8 KB of RAM in a 28-pin SSOP package. It integrates a USB 2.0 full-speed On-The-Go (OTG) controller alongside traditional serial peripherals (I²C, IrDA, SPI, UART/USART), and exposes 19 general-purpose I/O pins. A 16-bit microcontroller (MCU) is a class of embedded computing device that processes instructions on 16-bit-wide data paths, delivering a strong balance between 8-bit simplicity and 32-bit performance. Within the broader taxonomy, a 16-bit MCU sits inside the microcontroller hierarchy -> microcontroller -> embedded processor -> semiconductor device. The PIC24FJ family specifically emphasizes eXtreme Low Power (XLP) operation, positioning it for battery-powered applications where nanoWatt sleep currents and active-mode efficiency directly extend operating life. Key differentiating features of the PIC24FJ32GB002T-I/SS include its integrated USB OTG peripheral, the XLP nanoWatt technology sleep manager, and the 16 MIPS performance at 32 MHz (when operating at 3.3 V). The device provides 32 KB of self-programmable Flash and 8 KB of RAM, plus multiple 16-bit timers and configurable I/O. Compared to the non-USB PIC24FJ32GA002 sibling, the GB002's USB OTG controller makes it purpose-built for embedded USB-device and USB-host applications. From an architectural perspective, the part uses a modified Harvard RISC core with a 16-bit instruction word, supporting C-optimized code generation through Microchip's MPLAB XC16 compiler. Peripheral DMA, parallel master port, and on-chip temperature sensor round out the integration level. The internal 8 MHz FRC oscillator with PLL allows flexible system clocking without external crystals in many designs. Typical applications include USB HID peripherals such as custom keyboards, mice, and game controllers; embedded data-logging with USB mass-storage interfaces; low-power sensor hubs; and human-interface devices on consumer and industrial equipment. The USB OTG capability also makes the part suitable for point-of-sale terminals and portable medical instruments that must communicate directly with tablets or host PCs. A key design consideration when using this device is that the USB PHY requires a precise 48 MHz clock derived from the system oscillator; designers must configure the PLL correctly and respect the VUSB 3.3 V regulator pin. The DISVREG (disable-voltage-regulator) pin must be properly tied to ensure stable operation across all temperature and load conditions. This page consolidates distributor pricing, drop-in alternatives, and applied design notes not found in the manufacturer datasheet alone, helping engineers source and integrate the PIC24FJ32GB002T-I/SS with confidence.
