PIC24FJ128GB202T-I/SS Présentation
What is a 16-bit microcontroller? A 16-bit microcontroller is an embedded processor with a 16-bit data path and instruction word, sitting between 8-bit MCUs (limited performance, simple peripherals) and 32-bit MCUs (higher performance, more complex ecosystem). The PIC24F family is Microchip's 16-bit entry, falling under the broader PIC microcontroller hierarchy: PIC24F -> 16-bit MCU -> microcontroller -> embedded processor -> semiconductor. eXtreme Low Power (XLP) variants like this one target battery-powered applications by combining multiple low-power modes with peripheral operation that does not require CPU intervention.
Key features include 128 KB Flash program memory, 8 KB RAM, 16 MIPS performance at 32 MHz, hardware crypto engine with key storage and RNG, USB 2.0 full-speed On-The-Go with integrated PHY, a 10-bit ADC (1.1 Msps) configurable up to 12-bit mode via acquisition time, four 16-bit timers, two UART, two SPI, two I2C, RTCC, and multiple PWM/OC channels. The device operates from 2.0 V to 3.6 V, supports industrial -40 °C to +85 °C temperature range, and offers deep sleep currents in the nanoamp range typical of the XLP family.
The PIC24FJ128GB202T-I/SS uses a 16-bit modified Harvard architecture with a 24-bit instruction word and 16-bit data path, giving it 16 MIPS performance at 32 MHz core clock. The integrated crypto engine accelerates AES, DES, 3DES, and SHA-1/MD5/SHA-256 hash operations, while dedicated key storage keeps secrets isolated from general Flash. USB On-The-Go adds host- or device-role capability without an external PHY, reducing BOM and PCB area. The combination of eXtreme Low Power (XLP) sleep modes, hardware crypto, and full-speed USB makes this part especially well suited to battery-powered secure peripherals.
Typical applications include secure USB peripherals (token, smart card reader, authentication dongle), low-power IoT sensor nodes with secure boot and firmware update, medical data loggers requiring tamper-resistant local storage, industrial HMI panels with secure USB firmware update, secure access control readers, and consumer wearables that need authenticated USB charging or pairing. The hardware crypto engine and 128 KB Flash accommodate firmware overhead for TLS, secure boot, and OTA update logic.
When designing with this device, allocate a dedicated 0.1 µF decoupling capacitor per power pin and place it within 5 mm of the IC. The on-chip voltage regulator requires an external bulk cap; consult the datasheet for the recommended value. Use Microchip's MPLAB X IDE with the XC16 compiler and the MPLAB Code Configurator for peripheral setup; the CryptoAuthLibrary and USB framework are reference integrations. The 'T' suffix denotes tape-and-reel packaging for high-volume assembly.

Applications typiques
PIC24FJ128GB202T-I/SS convient pour 7 applications: Secure USB Authentication Token, Battery-Powered IoT Sensor Node, Medical Data Logger, Industrial Secure USB Firmware Update, Smart Card / NFC Reader, Wearable Fitness / Health Dongle, Secure Access Control Reader.
Secure USB Authentication Token
The PIC24FJ128GB202T-I/SS suits secure USB authentication tokens because the integrated hardware crypto engine accelerates AES-256, SHA-256, and 3DES while a dedicated RNG and isolated key storage protect secrets from main Flash. With USB 2.0 Full-Speed On-The-Go plus an internal PHY, the MCU enumerates as a USB HID or CCID device without an external transceiver, shrinking BOM and PCB area. The XLP deep-sleep current in the nanoamp range allows the token to remain plugged in indefinitely without draining the host. Engineers pair the part with the CryptoAuthLibrary and USB stack in MPLAB X with XC16. A 2.0 V minimum VDD accommodates single-cell Li-ion operation for portable authenticators.
Recommandé
Battery-Powered IoT Sensor Node
The PIC24FJ128GB202T-I/SS targets battery-powered IoT sensor nodes that need authenticated wireless connectivity or secure OTA updates. Its 16 MIPS at 32 MHz is more than enough to run an encrypted MQTT or CoAP stack, while the XLP sleep modes drop core current into the nanoamp range between transmissions. The 10-bit ADC at 1.1 Msps handles multiple analog sensors, and the hardware crypto engine accelerates TLS handshakes without burdening the CPU. The 2.0 V to 3.6 V VDD range supports direct connection to a single Li-ion or two alkaline cells. Real-world deployments routinely achieve multi-year battery life with duty-cycled sensing.
Recommandé
Medical Data Logger
Medical data loggers need tamper-resistant local storage of patient measurements, and the PIC24FJ128GB202T-I/SS delivers that through its hardware AES/SHA crypto engine plus isolated key storage. The 128 KB Flash accommodates long-term firmware while 8 KB RAM buffers continuous sensor streams. The 10-bit ADC integrates directly with thermistor or pulse-oximeter front-ends, and USB OTG allows secure retrieval to a clinician PC. The -40 °C to +85 °C industrial temperature range supports body-worn and ambient clinical environments. The XLP sleep modes keep standby current negligible between measurement cycles, critical for wearable medical devices.
Recommandé
Industrial Secure USB Firmware Update
Industrial HMIs and PLCs increasingly require authenticated firmware updates over USB, and the PIC24FJ128GB202T-I/SS fits that role with its USB OTG plus crypto engine. The MCU verifies signed firmware images via SHA-256 and decrypts payloads with AES before booting, preventing malicious injection. The 128 KB Flash allows dual-bank or A/B firmware schemes for failsafe updates. The wide 2.0 V to 3.6 V VDD range tolerates industrial 24 V bus rails stepped down with a simple buck regulator. The 28-SSOP package is easy to hand-solder for low-volume industrial prototypes.
Recommandé
Smart Card / NFC Reader

The 8 KB RAM holds transaction buffers, and 128 KB Flash accommodates application logic plus secure boot. The industrial temperature range supports outdoor payment terminals and access readers. Developers use MPLAB Code Configurator to bring up peripherals quickly.
Recommandé
Wearable Fitness / Health Dongle
Wearable fitness dongles that pair over USB to host PCs benefit from the PIC24FJ128GB202T-I/SS combination of XLP low power, USB OTG, and on-chip crypto for authenticated pairing. The MCU streams activity data over USB HID while a deep-sleep current below 1 µA preserves coin-cell life between syncs. The 10-bit ADC reads optical heart-rate or skin-conductance sensors, and 8 KB RAM buffers minutes of activity between transfers. The small 28-SSOP footprint fits wristbands and clip-on dongles. Reference firmware from Microchip's USB stack shortens time-to-market.
Recommandé
Secure Access Control Reader
Physical access control readers - door controllers, elevator floor locks - increasingly authenticate credentials locally to avoid network round trips. The PIC24FJ128GB202T-I/SS holds the credential database in protected Flash, verifies signatures via the hardware crypto engine, and logs events through UART or USB. The 128 KB Flash supports thousands of credential records, and 8 KB RAM holds the active transaction. The 32 MHz core runs the access decision in microseconds, and the industrial temp range handles outdoor reader enclosures. USB OTG enables field updates without opening the reader housing.

Notes de conception
Place a 0.1 µF ceramic decoupling capacitor within 5 mm of each VDD pin and a 10 µF bulk capacitor near the VUSB/VDD2 pin. The on-chip voltage regulator requires the bulk cap for stability across load transients. For battery-powered designs, route the 2.0-3.6 V VDD directly from the cell or regulator; do not exceed 3.6 V absolute maximum. Use the XLP sleep modes (Sleep, Deep Sleep, Retention) to drop core current into the nanoamp range when idle.
The 28-SSOP package (5.30 mm body, 0.65 mm pitch) requires precise SMT stencil apertures - use 0.4 mm pads with 0.1 mm web for reliable paste release. Keep the 32.768 kHz crystal traces short and symmetric to minimize jitter in RTCC applications. Route USB D+/D- as a 90-ohm differential pair with matched length and a common-mode choke near the connector to meet USB 2.0 FS eye compliance.
Do not leave the MCLR pin floating - tie it to VDD through a 10 kΩ pull-up for normal operation, or drive it directly for in-circuit debugging. PGED1/PGEC1 and PGED2/PGEC2 are mandatory for ICSP programming; leave them accessible. The peripheral pin select (PPS) feature remaps digital functions to RPn pins - configure via __builtin_write_OSCCONL before use. Do not assume the USB PHY operates below 3.0 V; verify against the datasheet USB electrical section.
Estimated: at full 32 MHz core, 3.3 V VDD, and active ADC + USB, the PIC24FJ128GB202T-I/SS typically dissipates under 30 mW. The 28-SSOP thermal resistance (theta_JA) is approximately 80 °C/W on a 4-layer JEDEC test PCB, giving a junction rise of only 2.4 °C above ambient at full load. The XLP sleep modes drop dissipation into the single-digit microwatt range. No heatsink is required for typical embedded designs.
