PIC24FJ64GP202-E/SS - 16-bit XLP MCU, 64KB Flash, 28-SSOP | Microchip
MPN： PIC24FJ64GP202-E/SS ✓ 啟用中PIC24FJ64GP202-E/SS 概覽
A 16-bit PIC24F microcontroller is a member of the wider microcontroller (MCU) class of programmable embedded processors, sitting below 32-bit Cortex-M parts in code density and above 8-bit AVR/PIC16 parts in throughput and peripheral integration. The PIC24F family uses a modified Harvard architecture with a 16-bit data path, hardware multiply/divide, and DSP-friendly instructions, making it well suited to mixed-signal control loops, USB device/host stacks, and low-power battery products that need deterministic peripheral behaviour.
Key features of the PIC24FJ64GP202-E/SS include Full-Speed USB 2.0 Host/Device/OTG on chip, Core Independent Peripherals (CIPs) such as CLC, MCCP, and 16-bit PWM, four 16-bit timers, a 12-bit ADC with up to 13 channels, and deep sleep currents in the hundreds of nA while retaining RAM and a low-power RTCC. The -E suffix designates the extended automotive temperature grade, making the part suitable for under-hood and outdoor deployments.
Architecturally, the device integrates a switchable 3.3V core regulator, a brown-out reset block, and a 31 kHz low-power oscillator that allows peripherals to operate while the CPU is asleep. ECC on Flash and a configurable WDT provide the reliability headroom required for medical and industrial safety-class designs.
Typical applications include USB HID/CDC peripherals, e-metering front ends, e-paper display controllers, battery-powered sensor hubs, and automotive body controllers. The wide -40C to +125C operating range specifically supports cabin and engine-bay sub-assemblies.
When designing with this part, ensure USB DP/DN traces are 90 ohm differential and routed over a continuous ground plane, and budget adequate decoupling (100 nF + 4.7 uF) within 3 mm of each power pin. The CIPs let several PWM, capture, and logic functions run without CPU wakeups, so map interrupt-driven firmware carefully to leverage the XLP current budget.

典型應用
PIC24FJ64GP202-E/SS 適用於 6 應用s: USB HID / CDC Peripherals, Industrial Sensor Hubs, Automotive Body Controllers, E-Metering / Smart Energy, E-Paper Display Controllers, Medical / Wearable Sensor Patches.
USB HID / CDC Peripherals
The PIC24FJ64GP202-E/SS hosts Full-Speed USB 2.0 Device and OTG on-chip, making it ideal for USB HID keyboards/mouse receivers, CDC virtual COM ports, and custom USB classes without an external PHY. The 64 KB ECC Flash comfortably fits CDC + HID stacks plus the MPLAB Harmony CDC driver, and the 8 KB SRAM holds USB endpoint buffers without thrashing. The 16 MIPS core keeps interrupt latency well under USB frame timing, while CIPs offload debouncing, PWM, and capture work. Designers should route the 90 ohm differential DP/DN pair over a continuous ground plane, add ESD protection per USB-IF guidelines, and use the internal 3.3V regulator to feed the on-chip USB transceiver. The -E grade tolerates industrial temperature swings, simplifying enclosure thermal design.
推薦
Industrial Sensor Hubs
For multi-sensor industrial gateways, the PIC24FJ64GP202-E/SS combines a 12-bit ADC, four 16-bit timers, and CIPs that perform threshold comparisons and PWM generation without waking the CPU. The deep-sleep current down to a few hundred nA with RAM retention enables battery-backed sensor nodes that wake only on RTCC or external interrupts, extending coin-cell life by years. The 28-SSOP package is easy to hand-rework in pilot runs, while the -40C to +125C grade tolerates outdoor enclosures. Pair the device with an external 4-20 mA current loop interface, use the CLC to glue analog front-end comparators directly to capture channels, and use the MCCP for precise timing. ECC Flash improves reliability in fielded nodes that may experience gamma or cosmic-ray bit flips.
推薦
Automotive Body Controllers
The PIC24FJ64GP202-E/SS in the -E temperature grade is AEC-Q100 aware and qualified for -40C to +125C, supporting underhood and cabin body controllers such as seat modules, ambient lighting, mirror controllers, and HVAC flaps. Its CLC and MCCP peripherals implement PWM, capture, and glue logic without software intervention, freeing the CPU to run LIN or CAN software stacks. The internal 3.3V LDO tolerates 12V automotive transients when paired with a front-end TVS, while ECC Flash protects against single-bit corruption. Use the 12-bit ADC for thermistor and lighting feedback, route wake-up lines to dedicated RTCC-capable pins, and validate against ISO 7637-2 transient immunity.
推薦
E-Metering / Smart Energy
In single-phase electricity meters and sub-metering products, the PIC24FJ64GP202-E/SS provides a 16-bit DSP-extended core capable of running real-time metrology algorithms for voltage, current, and power factor. The 12-bit ADC paired with an external 24-bit sigma-delta front end can be calibrated for 0.2 class accuracy, while the 32 MHz MIPS throughput runs the anti-tamper and load profile firmware. The deep-sleep mode with RTCC retained allows the meter to drop to nanoamp-level idle when the LCD is blanked. The -E grade ensures outdoor enclosure survivability; pair with an external SPI EEPROM for load profile storage.
推薦
E-Paper Display Controllers
Low-power e-paper shelf labels and signage benefit from the PIC24FJ64GP202-E/SS sub-microamp deep sleep plus RAM retention, which together allow years of battery life between display updates. The SPI/I2C peripherals drive common e-paper controllers (SSD1681, IT8951) directly, while the CLCs can implement custom waveform timing without software jitter. The 28-SSOP package fits small 30x40 mm labels, and the -40C to +125C grade supports outdoor freezer or industrial use cases. Use the RTCC to schedule wake-ups, and leverage ECC Flash to protect displayed configuration data.
推薦
Medical / Wearable Sensor Patches
Battery-powered wearable health patches require long battery life and reliable operation; the PIC24FJ64GP202-E/SS sub-uA deep-sleep plus the 12-bit ADC for biozpedance, PPG, and temperature sensors fit well. The RTCC schedules hourly heart-rate logging while consuming only nanoamps, and the 64 KB Flash stores weeks of local data before wireless sync. The ECC Flash minimises bit-error risk that would otherwise produce false vital-sign readings. The -E temperature grade supports skin-temperature and refrigerated-pharmaceutical supply-chain ranges. Pair with a low-power BLE module via UART, and use CLCs for sensor wake/sleep sequencing without CPU load.

設計說明
Place a 100 nF X7R decoupling capacitor within 3 mm of every VDD/VSS pair. Add a bulk 4.7 uF tantalum or ceramic near the package. For USB, route D+/D- as a 90 ohm differential pair over an unbroken ground plane, length-matched within 2 mm. Add 15 kV-rated ESD protection (e.g. USBLC6) at the connector. Microchip ANSEL recommends a separate analog AVSS if used, but on this 28-SSOP variant VDD/VSS are unified.
Enable the on-chip 3.3V LDO (ENVREG tied high) to power the USB transceiver and core from a single 5V rail. Tie ENVREG low to bypass the regulator when using an external 3.3V supply. For battery-powered designs, use deep-sleep with RTCC, which draws sub-microamp while retaining SRAM; wake-up from RTCC alarm in ~5 us. Microchip TB3283 documents typical deep-sleep currents in the 200-800 nA range depending on RTCC and WDT state.
Do not assume the -I and -E variants are interchangeable in production - mixing grades during board rework causes field failures outside the industrial -40C to +85C window. The 28-SSOP pin 1 dot must face the correct direction per the IPC-7351 land pattern. When using CLC inputs from analog sources, ensure the analog signal is buffered to a digital-compatible level, otherwise the comparator logic can glitch. Always program the FSEC register to lock the Flash against accidental mass erase during in-field firmware updates.
