PIC24FJ64GB110T-I/PF - 16-bit USB OTG MCU, 64KB Flash, 100-TQFP | Microchip

The Microchip Technology PIC24FJ64GB110T-I/PF is a 16-bit PIC24F microcontroller with USB On-The-Go (OTG) support, 64 KB of Flash program memory organized as 22K x 24 words, 16 KB of RAM, and a 100-pin TQFP (14x14 mm) surface-mount footprint. It is part of Microchip's PIC24FJ64GB110 family and integrates a modified-Harvard CPU core delivering up to 16 MIPS at 32 MHz CPU clock. A 16-bit microcontroller is a class of embedded processor that uses a 16-bit-wide data path, register file, and ALU - sitting architecturally between 8-bit MCUs (PIC16, AVR) and 32-bit Cortex-M parts. Within the MCU hierarchy it belongs to the PIC24F -> PIC24 -> 16-bit MCU -> microcontroller -> embedded processor -> semiconductor lineage. The "FJ" prefix denotes the Flash-based, low-power family; the "GB" infix signals integrated USB OTG; and "110" is the 100-pin pin-count and 64 KB Flash code member of that sub-family. Key features include 64 KB Flash, 16 KB RAM, an 8 MHz internal oscillator with 4x PLL (giving the 32 MHz CPU clock), a 17-bit x 17-bit single-cycle hardware multiplier, a 16-bit hardware divider, and a 16-bit working register array that the C compiler can target directly. Integrated peripherals include 3x I2C, 3x SPI, 4x UART, 23 independent timers, a 16-channel 10-bit ADC, and a full-speed USB 2.0 OTG controller with on-chip transceiver. The CPU is a five-stage modified-Harvard pipeline with a deterministic interrupt model and a C-friendly orthogonal instruction set, so it can execute compiled C at near-assembler efficiency. The on-chip 2.5 V/3.3 V regulator, deep-sleep modes drawing <100 nA standby current, and rich mixed-signal peripherals make the device attractive for low-power connected embedded nodes. Typical applications include USB peripherals and embedded hosts, human-interface devices, data loggers, industrial sensor nodes, low-power medical and consumer devices, and any battery-powered product that needs USB connectivity plus generous RAM buffering. The wide peripheral count also suits multi-protocol bridging such as USB-to-UART/SPI/I2C gateways. When designing with the PIC24FJ64GB110T-I/PF, allocate at least the bottom 4 KB of Flash for the USB stack and bootloader, respect the TQFP-100 PCB layout guidelines for the exposed thermal pad on the package family, and use Microchip's MPLAB X IDE plus the free MPLAB XC16 compiler for firmware development.

The combination of low standby current, ample RAM buffering, and multiple serial channels also makes it suitable for industrial sensor hubs, data loggers, and battery-powered IoT bridges. Industrial-grade temperature rating supports silicon design through the -40C to +85C range, while the 100-pin TQFP provides generous I/O headroom. When designing with this device, ensure that the USB OTG pin configuration matches the target role (device, host, or OTG) and that decoupling capacitors are placed close to the VDD/VSS pairs. The TQFP-100 footprint allows easy routing on 2-layer PCBs but a 4-layer stack-up with a dedicated ground plane is recommended for USB signal-integrity compliance.

PIC24FJ64GB202-E/MM

PIC24FJ64GB202-E/MM - 16-bit USB MCU, 64KB Flash, 28-QFN | Microchip

The Microchip PIC24FJ64GB202-E/MM is a 16-bit microcontroller from the PIC24F XLP family featuring an integrated full-speed USB 2.0 device controller, a hardware crypto engine with key storage and random number generator, 64KB Flash and 8KB RAM, packaged in a 28-pin QFN-S (6x6 mm) with exposed thermal pad. It runs at up to 32 MHz CPU clock (8 MIPS), operates from 2.0V to 3.6V, and is rated for the -40C to +125C extended industrial temperature range. What is a PIC24F XLP microcontroller: PIC24F XLP (eXtreme Low Power) is a 16-bit MIPS-based MCU family from Microchip Technology designed for ultra-low-power embedded applications. It belongs to the broader hierarchy microcontroller -> embedded processor -> semiconductor, and is engineered to consume nanoamp-level sleep currents while integrating USB, cryptographic, and analog peripherals on-chip. The GB2 sub-family adds full-speed USB and a hardware crypto module for secure connected nodes. Key differentiating features include hardware AES/SHA encryption, a random number generator, and a dedicated crypto key storage area; integrated USB 2.0 full-speed device with on-chip transceiver; eXtreme Low Power modes with sub-uA sleep currents (typical 100 nA in Deep Sleep); up to 16 channels of 10/12-bit ADC; and a 16-bit enhanced PMP/EPMP for parallel displays or memory expansion. The integrated crypto accelerator offloads AES, DES and SHA from the CPU, freeing MIPS for application code. Architecturally, the PIC24FJ64GB202 uses the standard PIC24F core with a 16-bit modified Harvard architecture, hardware multiply/divide, and a 7-channel DMA controller. The integrated USB PHY eliminates external transceivers, and the 28-QFN exposed pad provides a low-thermal-resistance path (~28 C/W theta_JA on a 4-layer JEDEC JESD51 board) for reliable operation at full 32 MHz. Typical applications include USB HID or CDC sensor and metering dongles, secure IoT edge nodes that authenticate and encrypt over USB, low-power portable medical accessories, battery-powered secure token/authenticator products, industrial HMI panels with USB diagnostics, and consumer wearables with USB charging/communication. The hardware crypto engine is especially useful in payment terminals, electronic locks and secure firmware update over USB. Design consideration: when laying out the PCB, the exposed thermal pad of the 28-QFN MUST be soldered to a sufficiently sized ground plane with thermal vias; this is critical for both electrical grounding of the MCU substrate and for heat dissipation at 32 MHz full load. Decouple VDD with a 100 nF ceramic placed within 3 mm of the VDD pin, and route the USB DP/DM pair as a 90 ohm differential with matching length to keep the Full-Speed eye diagram compliant. This page synthesizes distributor pricing, drop-in same-package alternatives, and PCB design notes that go beyond the manufacturer datasheet, helping engineers select and lay out the PIC24FJ64GB202-E/MM with confidence.

It operates at up to 32 MHz CPU clock delivering 16 MIPS of throughput, supports a wide 2.0-3.6 V supply range, and includes peripherals such as ADC, comparators, RTCC, and multiple UART/SPI/I2C interfaces. The part is rated for the -40C to +125C extended automotive temperature range, indicated by the "-E" suffix. An LDO (Low-Dropout) linear regulator is a type of voltage regulator that maintains a stable output voltage even when the input voltage is very close to the output voltage. This is part of the broader category hierarchy: microcontroller -> embedded processor -> integrated circuit -> semiconductor. 16-bit PIC24F devices fill the gap between 8-bit PIC MCUs and 32-bit ARM Cortex-M parts, balancing code density, deterministic interrupt latency, and low-power operation. The XLP (eXtreme Low Power) sub-family extends this with sub-uA sleep modes, making these parts suitable for battery-backed devices. Key features include eXtreme Low Power (XLP) technology with sub-uA sleep currents, an integrated crypto engine for AES and a random number generator, full-speed USB 2.0 OTG with on-chip transceiver, 64 KB self-programmable Flash, and a 16-channel 10-bit ADC with auto-scan.

PIC24FJ64GB202-I/MM

PIC24FJ64GB202-I/MM - 16-bit 32MHz 64KB Flash USB MCU | Microchip

The Microchip Technology PIC24FJ64GB202-I/MM is a 16-bit microcontroller from the PIC® XLP™ 24F family featuring an integrated full-speed USB 2.0 transceiver, hardware crypto engine, and eXtreme Low Power (XLP) technology. It integrates 64 KB Flash and 8 KB RAM, runs at up to 32 MHz (16 MIPS), and is housed in a 28-pin QFN-S (6x6 mm) package. A 16-bit microcontroller is a microprocessor whose data path, registers and ALU operate on 16-bit words, providing higher code density, more precise arithmetic, and richer peripheral integration than typical 8-bit MCUs. PIC24F devices sit in the PIC microcontroller taxonomy as: PIC microcontroller -> 16-bit MCU -> PIC24F family -> PIC24FJ XLP sub-family. They are widely used in battery-powered and USB-connected embedded designs where deterministic performance, low power, and small package size are required. The PIC24FJ64GB202 is differentiated by its built-in USB 2.0 Full-Speed OTG transceiver, integrated crypto engine with secure key storage, hardware random-number generator, and nanowatt XLP sleep currents. Core-independent peripherals (CIPs) such as the 16-bit PWM, multiple UART/SPI/I2C, a 10/12-bit ADC, and a real-time clock/calendar offload tasks from the CPU and let the device stay asleep longer. The on-chip 32 kHz low-power oscillator and wide peripheral set further reduce external component count. Architecturally, the device uses a 16-bit modified Harvard core with a 24-bit instruction word and 16-bit data path, supported by a deterministic interrupt controller and a flexible pin-mapping PPS (Peripheral Pin Select) layer. The combination of ECC-protected Flash, hardware crypto acceleration, and eXtreme Low Power modes makes the part well suited to designs where both data security and battery life are critical. With its small 6x6 mm QFN footprint, the device enables compact board layouts for space-constrained IoT products. Typical applications include USB peripherals such as HID keyboards, mice and CDC bridges, secure IoT sensor nodes, wearable health monitors, smart meters, secure remote controls, and low-power industrial sensor hubs. The integrated USB and crypto blocks reduce BOM cost in connected devices that must also meet IEC 60730 class-B or similar functional-safety check routines. When designing with this part, note that the 28-pin QFN-S package lacks an integrated debug header; route the dedicated PGECx/PGEDx programming pins to test pads or a tag-connect footprint for in-circuit programming. Plan USB DP/DM trace routing as a 90-ohm differential pair and provide a 5V-tolerant Vbus sense input through a divider.

PIC24FJ64GB202-I/SO

PIC24FJ64GB202-I/SO - 16-bit MCU 64KB Flash USB OTG Crypto | Microchip

The Microchip PIC24FJ64GB202-I/SO is a 16-bit microcontroller from the PIC® XLP™ 24F family that integrates a hardware crypto engine, secure key storage, and a true random number generator alongside a Full-Speed USB 2.0 On-The-Go (OTG) controller, all housed in a 28-pin SOIC package. The device combines 64 KB of ECC Flash program memory with 8 KB of RAM, executes instructions at 32 MHz (16 MIPS), and is fabricated on an ultra-low-power nanowatt XLP process. The integrated crypto module and tamper-resistant key storage make the part ideally suited for low-power embedded security applications such as secure peripherals, access-control terminals, and connected sensor nodes. Background: A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (RAM), and a set of peripherals onto one silicon die. The PIC24F family sits in Microchip's 16-bit modified-Harvard tier between the 8-bit PIC16/PIC18 families and the 32-bit PIC32MX/PIC32MZ families, sharing the MPLAB X IDE and XC16 toolchain ecosystem. Within the broader taxonomy: MCU -> 16-bit MCU -> PIC24F -> PIC24FJ (Flash, Java-friendly) -> PIC24FJ64GB2 family (USB OTG + crypto). Choosing a 16-bit part instead of an 8-bit MCU buys more deterministic interrupts, more code space, hardware peripherals such as USB and crypto, and a richer DSP-like instruction set, while staying in a far lower power budget than a 32-bit Cortex-M alternative. Key features include the PIC24F core with single-cycle 16x16 MAC, a USB OTG Full-Speed peripheral that supports Host, Device, and OTG roles without an external PHY, a hardware crypto engine supporting AES, DES, 3DES, and SHA-1/SHA-256 hash, an integrated true random number generator, dual analog comparators with programmable reference, a 10-bit ADC with up to 9 channels, four 16-bit timers, and an RTCC with calendar mode. Sleep current is rated in the nanoampere range in deep sleep modes, which is the defining characteristic of the XLP nanowatt technology. Typical applications include USB secure peripherals (key fobs, smart-card readers, authentication tokens), battery-powered IoT sensor nodes with on-device encryption, USB-OTG-enabled data loggers, secure industrial HMI panels, and consumer devices that need hardware-accelerated cryptography without a discrete security IC. The wide -40 °C to +85 °C operating range and the 28-pin SOIC footprint also make it easy to drop into legacy through-hole boards that have been migrated to surface mount. A primary design consideration is that the USB D+/D- pins must be routed as a 90-ohm differential pair to the connector, with the VBUS sensing pin tied to a divided-down 5 V. Decoupling must include a 100 nF ceramic on every VDD/VSS pair placed within 2 mm of the pins, and programmers must ensure the ICSP™ programming pins (PGECx/PGEDx) remain accessible for in-circuit firmware updates. This page synthesizes distributor pricing, drop-in SOIC alternatives, and practical USB+OTG design notes not found in the manufacturer datasheet, giving engineers a single reference for part selection, layout, and substitution.

It executes instructions at up to 32 MHz (16 MIPS) from a 2.0-3.6 V supply, combining nanoWatt XLP sleep modes with a peripheral set that targets low-power connected embedded designs. A 16-bit microcontroller (MCU) is a programmable processor that fetches, decodes and executes 16-bit-wide instructions while moving 8- or 16-bit data on internal buses. PIC24F devices sit in Microchip's MCU taxonomy between the 8-bit PIC16/PIC18 families and the 32-bit PIC32MX/dsPIC families. They offer higher code density and DSP-friendly arithmetic than 8-bit cores, with a lower cost and simpler toolchain than 32-bit Cortex-M parts, making them a common choice for mid-range embedded designs that need deterministic interrupt response and modest computational throughput. Key features of the PIC24FJ64GB204T-I/ML include 64 KB self-programmable Flash with ECC, 8 KB SRAM, the previously mentioned USB 2.0 full-speed OTG controller with on-chip PHY, a true random number generator, AES/SHA-1/SHA-256 hash hardware accelerator, four 16-bit timers, three UARTs, three SPI, three I2C, a 10-bit 1.1 Msps ADC with up to 13 channels, and a 9-bit 16-channel capacitive touch hardware module. The device operates across an industrial -40 C to +85 C range, supporting battery-powered applications such as portable medical monitors and energy-harvesting sensor nodes. From an architectural perspective, the PIC24FJ64GB204 uses a modified Harvard layout with a 16-bit data path, 24-bit instruction words, and a 16 x 16 hardware multiplier that accelerates DSP-style loops. The integrated USB OTG PHY eliminates the need for an external transceiver and supports Host, Device and On-The-Go dual-role operation, while the cryptographic engine off-loads AES-128/192/256, SHA-1, SHA-256 and MD5 from the CPU. Combined with nanoWatt XLP idle/sleep/retention modes drawing under 100 nA, the device lets engineers build USB-connected products that spend most of their life in deep sleep. Typical applications include USB HID/CDC devices such as PC peripherals and HID key fobs, secure payment terminals and contactless smart-card readers, wearable fitness and medical sensor pods, low-power IoT edge nodes with on-board crypto, and industrial sensor hubs that bridge UART/SPI/I2C peripherals to USB hosts. The integrated cryptographic engine is especially useful for firmware authentication and encrypted data logging. When laying out a board for this device, place the 12 MHz primary crystal within 5 mm of OSC1/OSC2 and keep the VUSB 3.3 V rail and its 0.1 uF + 1 uF ceramic bypass network as close to the USB power pin as possible. The QFN-44 package uses an exposed pad that must be soldered to a continuous ground plane for thermal and electrical performance - omitting this connection will degrade USB signal integrity and ADC accuracy.

Key features of the PIC24FJ64GC006T-I/MR include: dual ADC architecture (12-bit pipeline up to ~1 Msps plus 12-bit Sigma-Delta for high-resolution readings), on-chip op-amps usable as signal-conditioning gain stages, a charge-time measurement unit (CTMU) for capacitive touch and accurate time measurement, USB 2.0 Full-Speed On-The-Go with integrated PHY, a segmented LCD driver (up to 256 segments), and eXtreme Low Power (XLP) nanoWatt technology with deep-sleep currents below 1 uA typical. The 64-pin VQFN (MR) package exposes up to 52 digital I/O, RTCC with calendar, five 16-bit timers, two I2C, three SPI and four UART interfaces. The architecture uses a 16-bit modified Harvard core with a 16-element working register array and hardware multiply/divide. The Intelligent Analog chain is tightly coupled to the ADC, allowing hardware oversampling and a digital accumulator for 16-bit effective results. An internal 8 MHz FRC with PLL delivers the 32 MHz system clock, with options for 32 kHz secondary oscillator for low-power modes. Typical applications include portable medical and glucose meters, industrial sensor transmitters, USB data loggers, smart thermostats with segmented LCD, weighing scales, and battery-powered IoT edge nodes. The combination of low-noise analog, USB and LCD in one die allows a single MCU to replace multi-chip analog front-end designs. When designing with this part, route the analog supply/ground separately from the digital rails and place the VQFN-9x9 thermal pad with a 4x4 via array to keep junction temperature within spec during continuous USB + ADC sampling. The "T" suffix indicates tape-and-reel packaging; pinout and software are identical to the tray-version PIC24FJ64GC006-I/MR.

It belongs to the PIC24F 'GL' family of microcontrollers designed for ultra-low-power applications with Core Independent Peripherals (CIPs) and autonomous LCD animation support. A PIC microcontroller (MCU) is a single-chip computer integrating a CPU core, program memory (Flash), data memory (RAM), and peripherals such as timers, communication interfaces, and analog blocks. The PIC24F family uses a 16-bit modified Harvard architecture, positioning it between 8-bit PIC16/PIC18 MCUs and 32-bit PIC32 devices in Microchip's portfolio. Within power management hierarchy, PIC24FJ GL MCUs are classed as low-power embedded controllers under the broader category of embedded processors and microcontrollers. Key specifications include up to 256 LCD segments (8 commons and 32 segments), an integrated charge pump for battery-powered contrast management, sleep current down to a few hundred nanoamps with full RAM retention, and Core Independent Peripherals (CIPs) that offload animation tasks from the CPU. The 'GL' family specifically extends Core Independent animation to the segmented LCD driver through alternating dual display, blinking, and blanking functions. Operating voltage range is 2.0V to 3.6V with extended temperature (E-temp) range of -40C to +125C. The PIC24FJ64GL302 uses a 16-bit MIPS-based CPU with hardware multiplier, 64KB ECC Flash (64K x 8), 8KB SRAM, and multiple communication peripherals including UART, SPI, and I2C.
