PIC24FJ128GB202-E/MM Visão geral
A 16-bit microcontroller (MCU) is a programmable processor whose arithmetic logic unit, registers, and internal bus are 16 bits wide, balancing the 8-bit MCU's code density with the 32-bit MCU's throughput. PIC24F devices sit in Microchip's mid-range 16-bit portfolio between 8-bit PIC16/PIC18 parts and 32-bit PIC32 parts, sharing the same MPLAB X toolchain, XC16 compiler, and Harmony framework as the wider dsPIC/PIC24/PIC32 family. The "FJ" prefix denotes Flash program memory with the XLP sleep architecture, "GB" denotes integrated USB plus crypto, and "202" identifies the 28-pin pinout with 128 KB Flash.
Key features of the PIC24FJ128GB202-E/MM include: 128 KB (43K x 24) Flash program memory with self-programming and live update, 8 KB SRAM, integrated hardware crypto engine supporting AES, DES, 3DES, SHA-1/SHA-256 and RNG, USB 2.0 FS device/host/OTG with on-chip transceiver and PHY, two I2C, two SPI, up to two UART, two comparators, a 10-bit ADC with up to 9 channels, 5-bit DAC, three 16-bit timers, RTCC with calendar, and a chargeable nanoWatt XLP deep-sleep mode drawing sub-µA currents. The on-chip 32 kHz crystal-less USB PLL and the CTMU touch-sensing peripheral reduce external BOM cost. The QFN-S (6x6 mm) package provides a thermally efficient exposed paddle suitable for hand-held and USB-powered devices.
The PIC24FJ128GB202 architecture pairs a modified Harvard CPU with a 24-bit instruction word for compact code density, a single-cycle hardware multiplier, and a deterministic interrupt controller. The integrated crypto block offloads AES-128/192/256 and SHA operations from the core, so secure firmware updates, signed firmware boot, and TLS-style handshakes run in milliseconds rather than tens of milliseconds. The USB block shares DMA with the rest of the peripherals and supports device, host, and OTG roles, eliminating the need for an external PHY in most token, HID, CDC, and Mass Storage designs.
Typical applications for this part include USB smart-card and authentication tokens, secure medical data loggers with USB charging/docking, encrypted industrial sensor hubs that stream over USB, low-power IoT edge nodes that need both USB firmware update and secure boot, e-metering and tamper-resistant metering devices, and battery-powered consumer accessories such as USB-C hearables and wearables. Designers choose the "E" temperature grade (-40C to +125C) for industrial and extended-temperature environments.
A practical design tip: route the USB D+/D- pair as a 90-ohm differential microstrip with ground stitching vias on both sides, keep the 27-ohm series resistors within 4 mm of the IC, and place the VBUS bulk capacitor as close as possible to the VBUS pin to pass USB compliance and ESD tests. The QFN exposed paddle must be soldered to a continuous ground copper pour with thermal vias to meet the 1.5 W dissipation budget in enclosed industrial enclosures.

Aplicações típicas
PIC24FJ128GB202-E/MM é adequado para 6 aplicaçãos: USB Secure Authentication Tokens, Encrypted Industrial Sensor Hubs, Secure Medical Data Loggers with USB Dock, Low-Power IoT Edge Nodes with USB Firmware Update, Battery-Powered USB-C Wearables, Tamper-Resistant Smart Energy Meters.
USB Secure Authentication Tokens
The PIC24FJ128GB202-E/MM is purpose-built for USB authentication and secure-token products because its on-chip USB 2.0 full-speed controller eliminates the external PHY while the hardware AES/SHA/RNG engine signs challenges in milliseconds. The 128 KB Flash stores FIDO2/U2F applets and the 8 KB SRAM holds AES-256 session keys without external memory. Designers route D+/D- as a 90-ohm differential pair and rely on the integrated 3.3V LDO to power the core directly from VBUS. Compared to a discrete MCU plus external crypto IC, the single-chip GB202 cuts BOM cost and PCB area by roughly 40 percent.
Recomendado
Encrypted Industrial Sensor Hubs
The PIC24FJ128GB202-E/MM serves industrial sensor-hub designs that must encrypt field telemetry before forwarding via USB to a host PC or PLC. Its hardware AES engine encrypts each sensor sample on the fly, and the 32 MHz MIPS core plus DMA can sample the 10-bit ADC and push encrypted packets over USB CDC without bottleneck. The -40 C to +125 C E-grade survives outdoor cabinets and motor-drive enclosures. The XLP nanoWatt sleep with RTCC retention lets a battery-backed hub idle at sub-microamp until a sensor interrupt wakes it for a burst transmission.
Recomendado
Secure Medical Data Loggers with USB Dock
The PIC24FJ128GB202-E/MM fits medical wearables and bedside loggers that record patient data to internal Flash and then securely transfer it over USB to clinician workstations. Its 128 KB Flash holds days of compressed vital-sign data, and the integrated SHA-256 engine signs each log block for tamper-evident audit trails. The 28-QFN-S package at 6x6 mm fits wrist-worn form factors, while the E-grade temperature range tolerates body-heat operating conditions and sterilization cycles. The RTCC provides regulatory-grade timestamps for HIPAA-compliant logs.
Recomendado
Low-Power IoT Edge Nodes with USB Firmware Update
The PIC24FJ128GB202-E/MM is ideal for IoT edge nodes that spend 99 percent of their time in deep sleep and wake occasionally over USB to download signed firmware updates. The XLP nanoWatt Sleep with RTCC draws sub-microamp current, extending coin-cell life beyond five years for periodic telemetry applications. The integrated USB block doubles as both a CDC telemetry port and a DFU bootloader host, eliminating external USB-to-UART bridges. The CTMU peripheral adds capacitive wake-up buttons without a dedicated touch controller.
Recomendado
Battery-Powered USB-C Wearables
The PIC24FJ128GB202-E/MM drives hearables, fitness bands, and USB-C wearables where the same silicon must act as both a USB device (for charging and data sync) and a low-power sensor hub. Its integrated USB 2.0 full-speed OTG handles USB-C CC logic with minimal external FETs, and the 3.3V LDO can be powered directly from a 5V VBUS rail. The E-grade temperature rating tolerates skin temperature and pocket thermal spikes, while the 6x6 mm QFN-S fits inside sub-10 mm wearables. The hardware crypto engine enables secure pairing with companion phones.
Recomendado
Tamper-Resistant Smart Energy Meters
The PIC24FJ128GB202-E/MM is well suited for electricity, water, and gas meters that must securely log consumption, sign tariff data, and occasionally expose the meter through USB for service technicians. The hardware AES/SHA engine ensures signed firmware and signed billing events, while the 128 KB Flash retains months of interval data. The RTCC with calendar and the 32 kHz crystal-less USB PLL keep BOM minimal for cost-sensitive metering deployments. The E-grade temp range withstands outdoor meter enclosures from -40 C to +125 C.

Notas de projeto
Estimated: For USB compliance, route the D+ and D- pins (RC0/RC1) as a 90-ohm differential microstrip over a continuous ground plane, with ground stitching vias spaced every 4 mm along the trace length. Place the 27-ohm series resistors within 4 mm of the IC pins and tie VBUS to a 4.7 µF X5R ceramic bulk capacitor within 3 mm. The QFN exposed paddle must be soldered to a continuous ground pour with at least 9 thermal vias (0.3 mm drill) to meet the 1.5 W dissipation budget in sealed enclosures. Skipping the paddle solder connection causes thermal runaway at moderate loads.
The integrated 3.3V LDO from the USB block can power VDD directly from a 5V VBUS rail, eliminating an external regulator for bus-powered designs. Decouple VDD with a 100 nF plus 4.7 µF ceramic pair within 3 mm of the pin. For self-powered designs where the host can be disconnected, add a load-sharing FET so the LDO back-fees VBUS only when USB is connected, and never let VBUS exceed 5.5V. Sleep current with RTCC retention is sub-µA, so choose a low-leakage load switch on any sensor rail to preserve nanoWatt XLP currents.
Do not assume the PIC24FJ128GB202-E/MM boots with the internal FRC oscillator at 32 MHz - the default is 8 MHz FRC with PLL enabled, which can confuse USB enumeration timing on first power-up. Configure FOSC and PLL prescaler bits in the FOSCSEL/FOSC configuration words during programming, otherwise USB timing will violate the ±0.25 percent clock accuracy requirement. Also, the MCLR pin (RA5) must be pulled high through a 10 kohm resistor; leaving it floating produces intermittent reset events in noisy USB environments.
When using the integrated USB PHY in host mode, ensure the VBUS pin is properly current-limited per USB 2.0 spec (one unit load maximum without external boost). EMI from the USB block couples into adjacent analog inputs (AN0-AN8), so keep ADC traces at least 5 mm away from D+/D- and gate ADC sampling with a software blanking window during USB transmit. Use the CTMU as a guard-ring driver around touch sensors to prevent false wake-ups from USB packet noise.
