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.

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 - 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.

PIC24FJ64GB204T-I/ML

PIC24FJ64GB204T-I/ML - 16-bit 32MHz USB OTG MCU 64KB Flash | Microchip

The Microchip Technology PIC24FJ64GB204T-I/ML is a 16-bit microcontroller from the PIC24F XLP family that integrates 64 KB Flash, 8 KB RAM, a full-speed USB On-The-Go (OTG) transceiver, an ISO 7816 smart-card interface, and a hardware cryptographic engine in a 44-pin 8x8 mm QFN package. 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. This page synthesizes distributor pricing, drop-in alternative listings, and design notes on the QFN-44 thermal/USB layout that go beyond what is printed in the manufacturer datasheet, giving embedded engineers and procurement teams a faster path from selection to a working prototype.

PIC24FJ64GB204T-I/PT - 16-bit 64KB Flash USB OTG MCU | Microchip

The Microchip Technology PIC24FJ64GB204T-I/PT is a 16-bit microcontroller from the PIC24F XLP family that integrates a full-speed USB 2.0 On-The-Go (OTG) transceiver, a hardware crypto engine, and 64 KB of Flash program memory in a 44-pin TQFP (PT) package. The device operates at up to 16 MIPS (32 MHz internal oscillator with 2:1 instruction-cycle divisor) from a 2.0V to 3.6V supply, and includes 8 KB of SRAM plus peripherals such as a Real-Time Clock and Calendar (RTCC), 9-channel 10-bit ADC, multiple UART/SPI/I2C interfaces, and configurable logic cells. The integrated crypto module accelerates AES, DES, and 3DES operations, making the part attractive for embedded devices that require authenticated firmware updates or secure sensor telemetry without external companion ICs. Background Knowledge: A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and peripheral interfaces into one IC. The PIC24F XLP (eXtreme Low Power) family is Microchip's 16-bit flash MCU line built on a modified Harvard architecture with 16-bit instructions and 16 working registers, optimized for battery-powered applications where nanoWatt sleep currents and fast wake-up times dominate the energy budget. PIC24F parts typically slot below PIC24H/dsPIC33 performance MCUs but above 8-bit PIC16/PIC18 devices in both performance and peripheral integration. Key features of the PIC24FJ64GB204 include: nanoWatt XLP technology with typical sleep current below 1 µA, integrated USB 2.0 full-speed OTG with internal transceiver (no external PHY required), on-chip hardware crypto accelerator, configurable logic cells (CLC) for glue-logic replacement, Peripheral Pin Select (PPS) for flexible pin mapping, and a wide 2.0V to 3.6V operating range that supports direct 2xAA / 3xAA / Li-Ion battery operation. The 44-pin TQFP package offers a balance between hand-solder-friendly lead pitch and small footprint, which simplifies prototype and low-volume production. Typical applications include low-power USB peripherals (HID, CDC, mass-storage), secure IoT sensor nodes with on-board encryption, medical telemetry dongles, industrial data loggers with authenticated firmware, consumer fitness wearables with USB charging/data, and battery-powered barcode scanners. The integrated OTG controller also allows the device to act as either a USB device or a limited USB host (for low-power peripherals such as keyboards or mice). When designing with this part, allocate sufficient decoupling (100 nF + 4.7 µF) near both VDD pins and reserve the D+/D- USB traces as a 90-ohm differential pair routed directly to the connector with the 15 kΩ pull-down resistors on the host side. The crypto engine consumes DMA channels that are shared with the ADC, so plan DMA arbitration in firmware. XLP sleep modes require careful peripheral clock gating to achieve the datasheet's sub-µA standby numbers.

PIC24FJ64GB406T-I/PT - 16-bit 32MHz MCU, 64KB Flash, USB OTG, Crypto | Microchip

The Microchip PIC24FJ64GB406T-I/PT is a 16-bit microcontroller from the PIC24F XLP family, featuring an integrated hardware crypto module, USB On-The-Go (OTG) controller, segmented LCD driver, and eXtreme Low Power (XLP) technology. It delivers 16 MIPS performance at 32 MHz from a 64 KB Flash program memory and 8 KB SRAM, all housed in a 64-pin TQFP (10x10 mm) package with 52 digital I/O pins. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals such as timers, communication controllers, ADCs, and I/O pins. The PIC24FJ64GB406 belongs to the 16-bit PIC24F sub-family, which sits hierarchically above 8-bit PIC MCUs and below 32-bit ARM Cortex-M devices, offering higher code density and richer peripherals while retaining low power consumption. This makes the part especially suitable for battery-powered embedded products that need more compute than 8-bit cores can offer but cannot justify a Cortex-M0 design cost. Key features include 64 KB Flash (22K x 24 instruction words), 8 KB SRAM, integrated USB 2.0 full-speed OTG with PHY, hardware AES/SHA crypto engine, up to 52 GPIO pins, a segmented LCD driver supporting up to 192 segments, multiple UART/SPI/I2C interfaces, a 10-bit ADC, and ultra-low-power sleep modes drawing less than 1 uA with RTCC retention. The wide 2.0 V to 3.6 V operating range lets the device run directly from a single Li-ion cell or two AA cells. Typical applications include secure IoT sensor nodes, USB HID peripherals, smart meters with LCD displays, electronic shelf labels, medical portable monitors, and secure payment terminals where the on-chip hardware crypto accelerator offloads AES/SHA workloads from the CPU. The combination of USB OTG, LCD, and crypto in a single die reduces both BOM cost and PCB area. When designing with this device, ensure the 64-pin TQFP land pattern matches the variant ordered. The trailing "/PT" suffix confirms the 10x10 mm TQFP-64 package; the related "/MR" suffix denotes a smaller 64-pin QFN package and is therefore NOT drop-in compatible. For long battery life, leverage the deep-sleep and Retention modes documented in the Microchip XLP family datasheet rather than relying on Idle mode.
