PIC24FJ128GA202-I/SS 개요
A 16-bit flash microcontroller is a microprocessor that fetches and executes 16-bit-wide instructions from non-volatile Flash memory, providing higher code density and richer peripherals than 8-bit MCUs while remaining easier to program than 32-bit cores. Within the broader semiconductor taxonomy, the PIC24FJ128GA202 sits in the PIC24F XLP subfamily, which extends the PIC microcontroller line -> PIC24F family -> 16-bit MCU -> microcontroller (MCU) -> embedded processing IC -> semiconductor. Its integrated crypto engine with ISO 7816 support makes it especially attractive for contactless smart-card, secure-element, and authentication endpoints that previously required a companion secure IC.
Key features include 128 KB self-programmable Flash with ECC, 8 KB SRAM, hardware AES/SHA/DES/Triple-DES/RSA/ECC acceleration (Microchip proprietary crypto library), four 16-bit timers, two UART/I2C/SPI modules, a 10/12-bit ADC with up to 16 channels, five 16-bit PWM/CCP/SCCP channels, a Real-Time Clock and Calendar (RTCC) with calendar mode, and an integrated 32 kHz low-power oscillator. The XLP nanoWatt technology delivers standby currents below 20 nA (typical) in deep-sleep modes, while the 32 MHz internal oscillator eliminates an external crystal in cost-sensitive designs.
Typical applications include secure contactless payment terminals, IoT sensor nodes with TLS acceleration, smart energy meters with cryptographic signing, battery-powered medical wearables, and ISO 7816 smart-card interface boards. In each case the part combines the right mix of secure-element hardware and eXtreme Low Power run/sleep modes to extend battery life while offloading cryptographic primitives from the main CPU.
When designing with this part, plan for a decoupling network of 100 nF + 4.7 uF ceramic caps on VDD/AVDD with traces kept short to the SSOP body. Use the 32 kHz SOSC crystal only if RTCC calendar drift below ±5 ppm is required; otherwise the internal LPRC oscillator is sufficient for low-power timekeeping.

설계 노트
Per Microchip datasheet DS39747A, place a 100 nF ceramic decoupling capacitor on every VDD pin within 5 mm of the package body, plus a single 4.7 uF bulk capacitor on the main VDD rail. Use a ferrite bead or pi-filter on AVDD if ADC measurements are noisy. The XLP Sleep+RTCC current is specified at 20 nA typical only when all GPIO are configured as outputs driving defined levels, so set unused pins to output-low rather than floating input to minimize phantom current draws.
The 28-SSOP package has a junction-to-ambient thermal resistance (theta_JA) of approximately 78 °C/W in still air. At maximum active current (around 12 mA at 32 MHz, 3.3 V) dissipation is approximately 40 mW, yielding a junction rise of just 3 °C - well within the 85 °C industrial limit. For Extended -E variants at +125 °C ambient, no heatsink is required because the SSOP is rated to that maximum junction temperature.
Keep the 28-SSOP trace lengths under 25 mm to minimize EMI and ADC sampling error. Per Microchip datasheet DS39747A, use a continuous ground plane under the SSOP body and route analog traces (AN0-AN9, VREF+, VREF-) away from digital switching lines like PWM outputs. If using the external 32.768 kHz SOSC crystal for RTCC, place the crystal within 5 mm of SOSCI/SOSCO and guard the traces with ground pour to keep RTC drift below ±20 ppm.
Do not exceed 3.6 V on VDD - the PIC24FJ128GA202-I/SS is NOT 5 V tolerant on any pin. Per datasheet DS39747A, the brown-out reset is factory-trimmed; do not bypass the BOR fuse or the part may corrupt Flash during power-down. When programming with ICSP, ensure PGECx/PGEDx lines are not assigned to peripherals in user firmware or debug access will fail. Do not rely on the internal 8 MHz FRC accuracy above ±2 % over temperature; use the PLL-locked 32 MHz only for protocols tolerant of this drift, otherwise fit an external crystal.
Per Microchip datasheet DS39747A, the 10-bit ADC achieves 10 ENOB only with an input bandwidth below 500 Hz and an external 4.7 uF + 100 nF capacitor network on VREF+ when used. The crypto engine produces brief current spikes during AES/DES/RSA operations; isolate AVDD with a ferrite bead from VDD if ADC sampling coincides with crypto tasks. Use hardware CRC and DMA for ADC double-buffering at full 200 ksps throughput.
