PIC24FJ128GA202T-I/MM - 16-bit 32MHz 128KB Flash MCU | Microchip
MPN: PIC24FJ128GA202T-I/MM ✓ Hoạt độngPIC24FJ128GA202T-I/MM Tóm tắt
A PIC24F family microcontroller belongs to the broader category of 16-bit RISC microcontrollers within Microchip's PIC family. The PIC24F line specifically targets ultra-low-power applications through XLP technology, and is widely deployed in battery-powered IoT, consumer, and industrial sensor products where long battery life, deterministic interrupt response, and integrated cryptographic peripherals are required. The 16-bit data path and 24-bit instruction word enable efficient C-code execution while preserving a deterministic PIC architecture that engineers have trusted for decades.
Key features of the PIC24FJ128GA202T-I/MM include 128 KB of Flash program memory (43K x 24 words), 8 KB of SRAM, hardware crypto acceleration, multiple communication peripherals (UART, SPI, I2C), and a 10/12-bit ADC subsystem. The integrated crypto engine accelerates AES, DES, and 3DES operations, making the part suitable for secure-connected applications. XLP technology delivers nanoWatt deep-sleep currents, allowing years of operation from a single coin-cell battery in duty-cycled sensor nodes.
The device operates from a 2.0 V to 3.6 V supply, supports industrial -40 °C to +85 °C temperature range, and is qualified to AEC-Q100 for automotive deployment in non-safety-critical subsystems. The 28-QFN-S package with exposed pad provides low thermal resistance and a compact 6 x 6 mm footprint suitable for space-constrained wearable and IoT designs.
Typical applications include secure IoT sensor nodes, low-power wireless Mote platforms (when paired with an RF transceiver), battery-powered medical wearables, automotive body controllers, smart metering, and secure authentication peripherals. When designing with this part, follow Microchip's MPLAB X IDE and XC16 toolchain for firmware development, and consult the family datasheet (DS39747) for crypto engine register definitions and power-management mode transitions.

Ứng dụng tiêu biểu
PIC24FJ128GA202T-I/MM phù hợp cho 6 Áp dụngs: Battery-Powered IoT Sensor Nodes, Secure Wearable Health Monitors, Automotive Body Control Modules, Smart Metering and Utility Endpoints, Secure Authentication Peripherals, Low-Power Industrial Sensor Hubs.
Battery-Powered IoT Sensor Nodes
The PIC24FJ128GA202T-I/MM is well-suited to battery-powered IoT sensor nodes because its XLP nanoWatt technology delivers sub-microamp deep-sleep currents while the integrated AES/DES/3DES crypto engine secures uplink payloads without burdening the 16 MIPS core. With 128 KB Flash the part runs an MQTT-SN or CoAP stack plus application code; the 2.0-3.6 V supply runs directly from a 3 V coin-cell or 2xAA pack, removing the need for a boost converter and extending field-deployment life to several years on a duty-cycled measurement cycle.
Được đề xuất
Secure Wearable Health Monitors
The PIC24FJ128GA202T-I/MM fits wearable health monitors where AES-accelerated BLE pairing and XLP battery life are mandatory. The 28-QFN-S (6x6 mm) footprint fits inside a wristband form factor, while the on-chip 10/12-bit ADC digitizes pulse-oximeter or temperature sensors without an external analog front-end. Compared to a discrete crypto IC + general MCU solution, the integrated engine cuts BOM cost and quiescent draw, and the 2.0 V minimum supply lets the design run from a single rechargeable Li-ion cell down to the safe cutoff.
Được đề xuất
Automotive Body Control Modules
The PIC24FJ128GA202T-I/MM is qualified to AEC-Q100 Grade 3 and operates across -40 C to +85 C, qualifying it for non-safety automotive body controllers such as interior lighting, seat controllers, and door modules. Its 21 I/O pins drive LED drivers and relay FETs directly, the UART/SPI/I2C peripherals connect to the vehicle CAN gateway via an external transceiver, and the hardware crypto engine secures diagnostic (UDS) sessions without a separate secure element. The exposed-pad QFN-S package improves thermal dissipation under high I/O switching loads.
Được đề xuất
Smart Metering and Utility Endpoints
The PIC24FJ128GA202T-I/MM is well-matched to electricity, gas, and water meter endpoints where secure communication, decade-long battery life, and compact packaging are required. Its 128 KB Flash stores the DLMS/COSEM or wireless M-Bus stack; the XLP sleep mode drops below 1 uA so a primary lithium cell lasts the calibration interval; and the integrated AES engine authenticates the meter against the head-end system, preventing tamper and replay attacks. The 28-QFN-S footprint fits inside the meter base without a daughter board.
Được đề xuất
Secure Authentication Peripherals
The PIC24FJ128GA202T-I/MM's hardware AES/DES/3DES engine makes it ideal for accessory authentication, anti-counterfeiting tokens, and secure peripherals that pair with a host over USB, SPI, or I2C. The 16 MIPS core handles the authentication handshake in firmware while the crypto engine offloads the cipher; the 8 KB RAM buffers challenge-response exchanges without external memory; and the 2.0-3.6 V supply matches the host rail. The exposed-pad QFN-S eases thermal management during sustained crypto workloads.
Được đề xuất
Low-Power Industrial Sensor Hubs
The PIC24FJ128GA202T-I/MM serves as a low-power hub in industrial sensor networks that aggregate multiple analog and digital sensors over UART, SPI, and I2C and forward them to a central PLC or gateway. The 10/12-bit ADC subsystem reads 4-20 mA or 0-10 V transducer channels through external signal conditioning; the XLP sleep mode drops to nanoWatt levels between scan cycles; and the 21 I/O pins drive status LEDs, isolated outputs, and relay coils. The -40 C to +85 C range handles factory-floor temperatures.

Ghi chú thiết kế
Route the QFN-S exposed pad to a continuous ground plane on the top layer stitched with at least 8 thermal vias to the inner ground plane. Estimated: with a 0.6 mm via diameter and 1 oz copper, this via array drops theta_JA from ~50 C/W (no vias) to approximately 28 C/W, allowing the part to source 30 mA continuously from the I/O bank without exceeding 100 C junction at 25 C ambient.
Place a 100 nF ceramic decoupling capacitor within 3 mm of the VDD pin (pin 6) and a bulk 10 uF X5R ceramic within 10 mm. For RF-noise-sensitive applications, add a ferrite bead on the analog VDD rail and a separate 100 nF cap on the analog supply pin. The exposed pad must NOT be used as the sole ground - it must be soldered to a thermally-via'd ground pad AND a digital ground plane.
Do not enable the crypto engine without first initialising the peripheral clock and clearing the CRYCONbits.PICKEY bit - leaving the PICKEY unset blocks crypto operations silently. When migrating from PIC24FJ64GA202 firmware, remember the memory map shifts because Flash is doubled; verify linker scripts and __ICD2__ vectors before flashing. The MCLR pin (pin 18) requires a 10 kohm pull-up to VDD for reliable reset.
Estimated: at 32 MHz / 3.3 V core supply, the part dissipates roughly 25 mW of active power plus I/O switching losses. With theta_JA of 28 C/W (after via stitching), junction temperature rise is only 0.7 C - well within the 125 C automotive limit. At maximum I/O sourcing (21 pins x 10 mA) the I/O bank adds another 70 mW, raising the junction to ~50 C above ambient.
