PIC24FJ128GA202-E/SS 개요
What is a PIC24 microcontroller? A PIC24 is a 16-bit modified-Harvard RISC microcontroller from Microchip's PIC24F family, positioned between the 8-bit PIC16/PIC18 families and the 32-bit PIC32MX devices. Within the wider taxonomy, PIC24 sits inside the MCU (microcontroller unit) class, which itself is part of embedded computing, sitting under the broad semiconductor hierarchy. PIC24F parts use the XLP technology portfolio to deliver sleep currents as low as nanoamperes while retaining peripheral activity, and the cryptographic engine in this part provides hardware acceleration for AES, DES, and 3DES plus a true Random Number Generator (RNG).
Key features include 128 KB Flash, 8 KB RAM, four DMA channels for low-CPU-overhead data movement, three enhanced analog comparators with rail-to-rail inputs, three on-chip programmable voltage references, a 10/12-bit A/D converter with up to 13 channels and 500 ksps throughput, and a Charge Time Measurement Unit (CTMU) used for capacitive touch sensing. Communication peripherals include I2C, SPI, UART with IrDA and LIN bus support, and a Parallel Master Port (PMP) for graphics or external memory expansion.
The architecture uses a 16-bit modified-Harvard core with a 24-bit instruction word, separate program and data paths, and a hardware Multiply/Divide unit. This enables 32-bit arithmetic in a single cycle and deterministic interrupt latency, which is essential for real-time control loops. The hardware crypto engine offloads AES/DES/3DES from the CPU, reducing firmware footprint and improving throughput versus software implementations on Cortex-M0 class parts.
Typical applications include low-power IoT endpoints with secure firmware updates, smart cards and RFID readers using ISO 7816, capacitive touch user interfaces with the CTMU, battery-powered medical monitors leveraging XLP sleep modes, and industrial sensor hubs with LIN or UART connectivity. The extended (-E) temperature grade supports -40C to +125C operation for harsh environments.
When designing with this part, choose a stable 3.3V rail for VCAP/VDD and follow the datasheet decoupling scheme. The internal FRC oscillator typically suffices without an external crystal, but low-USB-noise designs still benefit from a 32.768 kHz secondary oscillator for RTC accuracy.

일반적인 애플리케이션
PIC24FJ128GA202-E/SS 적합 용도: 7 애플리케이션s: Secure Low-Power IoT Sensor Node, Capacitive Touch User Interface, Smart Card / Secure Peripheral Reader, Battery-Powered Medical Wearable, Industrial Sensor Hub with LIN Bus, Secure Smart Meter Endpoint, Home Automation Touch Panel.
Secure Low-Power IoT Sensor Node
The PIC24FJ128GA202-E/SS fits secure IoT sensor nodes because its hardware cryptographic engine offloads AES-128 for TLS handshakes while the XLP sleep controller drops quiescent current to under 100 nA between transmissions, enabling multi-year battery life on a single CR2032 cell. The 13-channel 12-bit ADC handles multiple analog sensor inputs (temperature, humidity, battery voltage) at 200 ksps, and the 4-channel DMA moves ADC samples into RAM without waking the CPU, reducing active-mode energy per measurement.
추천
Capacitive Touch User Interface
The PIC24FJ128GA202-E/SS is ideal for capacitive touch UI designs because its on-chip Charge Time Measurement Unit (CTMU) measures capacitance changes on touch electrodes with sub-pF resolution, eliminating the need for an external touch controller IC. Combined with the 128 KB Flash for touch algorithms and gesture detection state machines, and the XLP sleep modes that keep average current under 5 uA in standby, the device powers sealed membrane keypads and small touch panels in white goods and medical equipment.
추천
Smart Card / Secure Peripheral Reader
The PIC24FJ128GA202-E/SS fits ISO 7816 smart card readers because the hardware AES and DES/3DES engines handle card authentication and session key generation in microseconds, offloading the CPU and freeing MIPS for application logic. The UART peripheral supports ISO 7816 T=0/T=1 protocols, the PMP can drive external secure memory or display, and the cryptographic RNG seeds key material without CPU post-processing. Security-sensitive peripherals such as payment terminals and eID readers benefit from the dedicated crypto engine and -40C to +125C extended temperature range.
추천
Battery-Powered Medical Wearable
The PIC24FJ128GA202-E/SS suits battery-powered medical wearables because XLP technology keeps deep-sleep current below 100 nA while retaining RAM and the real-time clock, extending coin-cell runtime to multi-year operation for continuous vital-sign monitors. The 32 MHz core and 16 MIPS handle ECG or SpO2 DSP front-end processing, the 12-bit ADC samples bioelectric signals at 500 sps per channel, and the hardware crypto engine secures BLE pairing keys. The extended -40C to +125C grade covers body-temperature and sterilization environments.
추천
Industrial Sensor Hub with LIN Bus
The PIC24FJ128GA202-E/SS fits industrial LIN-bus sensor hubs because the UART peripheral natively supports LIN 1.3/2.0/2.1 slave communication, the CTMU handles capacitive level sensing in tanks, and the extended -40C to +125C temperature grade survives under-hood and outdoor installations. The 128 KB Flash stores LIN node configuration and diagnostic logs, the hardware AES authenticates LIN bus diagnostics, and the four DMA channels allow parallel sampling of multiple sensors without CPU load.
추천
Secure Smart Meter Endpoint
The PIC24FJ128GA202-E/SS is well-suited to smart meter endpoint designs because the hardware AES engine secures DLMS/COSEM or Wireless M-Bus communications, the CTMU and 12-bit ADC measure energy pulses with high accuracy, and XLP sleep modes keep average consumption below the IEC 62053-22 idle budget. The 128 KB Flash holds metering firmware plus secure bootloader, and the 8 KB RAM buffers tariff tables and time-of-use data for billing intervals.
추천
Home Automation Touch Panel
The PIC24FJ128GA202-E/SS fits home automation touch panels because its CTMU drives up to 13 capacitive touch electrodes with no external controller, the PMP peripheral drives small TFT or OLED displays up to 320x240 resolution, and the hardware AES engine secures ZigBee or Thread commissioning keys. The XLP sleep modes keep quiescent current low for always-on wall-mounted panels, while the 32 MHz core renders UI animations smoothly.

설계 노트
Place a 10 uF bulk capacitor in parallel with a 100 nF ceramic decoupling capacitor close to each VDD/VSS pair (pins 8/9 and 19/20) to suppress switching transients from the core and I/O toggling. Connect the VCAP pin (pin 28) to VSS through a 10 uF ceramic capacitor with low ESR; the internal voltage regulator requires this capacitor for stable 1.8 V core operation. Estimate: total bulk capacitance should be at least 10 uF per VDD pin plus 1 uF per active peripheral cluster.
Keep the trace from VCAP (pin 28) to its decoupling capacitor as short as possible, ideally under 5 mm, because long traces add parasitic inductance that destabilizes the internal LDO and can cause core voltage droop during DMA bursts. Route the MCLR line (pin 1) with a guard ring or keep it short to avoid false resets from EMI. Place the 32.768 kHz crystal traces (RA4/RA5) symmetric and short, with a ground guard trace beneath to reduce noise injection into the secondary oscillator.
Do not assume any PIC24FJ128GA202-I/SS substitute automatically supports the -40C to +125C extended temperature range; the /I industrial variant is limited to -40C to +85C, so designs qualified at high temperature must use the /E suffix. Avoid using the internal FRC oscillator for UART baud rates above 115200 bps without enabling the PLL; FRC accuracy (~2%) is insufficient for reliable LIN or RS-485 communication. When the cryptographic engine is enabled, ensure firmware does not leave partial key values in RAM after use; clear key buffers with the CLR RAM instruction to reduce side-channel leakage.
