PIC24EP32GP202T-E/SO Descripción general
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, volatile and non-volatile memory, and programmable peripherals. The PIC24E family uses Microchip's 16-bit modified-Harvard architecture with DSP instructions, occupying the mid-range performance tier between 8-bit PIC MCUs and 32-bit ARM Cortex-M devices. Within the broader MCU taxonomy, PIC24EP devices sit under: PIC24 family -> dsPIC33/PIC24E 16-bit MCU class -> general-purpose MCU -> embedded microcontroller -> semiconductor.
Key features include a 16-channel 10-bit ADC (1.1 Msps), two UART, one SPI, one I2C, one CAN (in GP variants), and peripheral trigger generator (PTG) for hardware-accelerated sequencing. The device includes a Charge Time Measurement Unit (CTMU) for capacitive touch sensing and on-chip op-amps for signal conditioning. A high-speed 70 MIPS core and DSP engine deliver up to 40 DMIPS and support fractional arithmetic for motor-control and digital-filter routines.
The PIC24EP architecture uses a 24-bit instruction word with 16-bit data paths, allowing single-cycle MAC operations. Internal Phase-Locked Loop (PLL) multiplies an external crystal or oscillator to the full core clock. Hardware stack and 16x16-bit working-register array accelerate context switching and interrupt latency.
Typical applications include automotive body modules, BLDC motor control, sensor interface boards, and industrial automation nodes. The AEC-Q100 qualification also extends use cases into chassis electronics and instrument clusters. The 28-SOIC footprint simplifies hand-prototyping and rework-friendly designs.
When designing with this MCU, ensure the VDD rail is decoupled with 100 nF and 10 µF capacitors placed within 5 mm of each VDD pin. Leave room for an ICSP programming header (PGECx/PGEDx pins) accessible on the PCB edge for in-circuit firmware updates.

Aplicaciones típicas
PIC24EP32GP202T-E/SO es adecuado para 7 aplicacións: Automotive Body Control Module, BLDC Motor Commutation Controller, Capacitive Touch User Interface, Industrial Sensor Node with CAN, Battery-Powered Data Logger, USB-to-CAN Bridge / Diagnostic Tool, Medical Monitoring Sensor Hub.
Automotive Body Control Module
The PIC24EP32GP202T-E/SO's AEC-Q100 qualification and -40C to +125C operating range make it ideal for automotive body control modules controlling lighting, mirrors, and door locks. Its ECAN module interfaces with the vehicle CAN bus at 500 kbps, while the 60 MIPS core handles debounced switch inputs and PWM-driven LED dimming without offloading to a companion IC. Using a 32 KB Flash budget allows feature-rich body modules (central locking, welcome animation, RKE) with margin for bootloader and diagnostics.
Recomendado
BLDC Motor Commutation Controller
Although the PIC24EP32GP202T-E/SO is a GP device, its 16-bit DSP instructions and 5x 16-bit timers allow it to act as a small BLDC commutation controller driving external gate drivers via PWM. The 60 MIPS throughput handles back-EMF sampling at 25 kHz with proportional-integral (PI) loop closure, while the on-chip op-amps condition motor-phase current for ADC measurement. For full motor-control peripheral integration, choose the PIC24EP32MC202 pin-compatible variant.
Recomendado
Capacitive Touch User Interface
The PIC24EP32GP202T-E/SO integrates Microchip's CTMU (Charge Time Measurement Unit) which, combined with the 10-bit ADC and 16 channels, delivers reliable capacitive touch sensing for up to 16 buttons or a small matrix keypad. The DSP engine runs touch-software libraries (mTouch) to provide proximity, water-tolerance, and gesture algorithms. Designers benefit from the -40C to +125C range for outdoor appliance and industrial control panels.
Recomendado
Industrial Sensor Node with CAN
The PIC24EP32GP202T-E/SO fits industrial sensor nodes that report temperature, pressure, and vibration over ECAN to a master PLC. Its 10-bit 1.1 Msps ADC captures fast analog signals, while DMA channels move conversion data to RAM without CPU intervention, leaving the 60 MIPS core free to run calibration and diagnostic algorithms. The 28-SOIC package is hand-solderable for prototype builds and supports wider thermal margins than QFN.
Recomendado
Battery-Powered Data Logger
The PIC24EP32GP202T-E/SO with its 3.0-3.6 V supply and wide temperature grade is well suited to battery-powered automotive data loggers (e.g., event-data recorders, fleet telematics). The 32 KB Flash stores firmware and small log buffers; the 2 KB RAM accommodates circular buffers before flush-to-Flash events. Sleep current and 16-bit DSP efficiency favor longer battery life when running periodic ADC sampling at 1 Hz.
Recomendado
USB-to-CAN Bridge / Diagnostic Tool
The PIC24EP32GP202T-E/SO with its UART and ECAN can act as a low-cost USB-to-CAN diagnostic adapter for automotive service. UART bridges to a USB-UART IC (FTDI/MCP2200) on the host side, while ECAN connects to the OBD-II bus through an MCP2551 transceiver. The 60 MIPS core runs the ISO 15765 (CAN diagnostic) transport layer in software, eliminating a dedicated protocol controller.
Recomendado
Medical Monitoring Sensor Hub
The PIC24EP32GP202T-E/SO's extended temperature grade and AEC-Q100 reliability data extend its use into medical sensor hubs (non-life-support) where IEC 60601 EMC margins are challenging. The on-chip op-amps condition ECG/EMG analog front-ends, while the CTMU drives pulse-oximeter timing. The 32 KB Flash accommodates custom DSP-filter and feature-extraction routines.

Notas de diseño
Decouple each VDD/VSS pair with a 100 nF X7R ceramic capacitor placed within 5 mm of the package pins. Add a bulk 10 µF tantalum or ceramic capacitor on the main 3.3 V rail to support transient loads from the ADC and ECAN modules. The PIC24EP32GP202T-E/SO draws up to 70 mA at 70 MHz FCY, so verify regulator headroom.
Do not leave the MCLR pin floating. Microchip datasheets require MCLR tied to VDD through a 10 kΩ pull-up for normal operation, or driven low through a 470 Ω resistor for manual reset. A floating MCLR can trigger spurious resets or prevent code execution on power-up. Add a 100 nF cap on MCLR to filter noise spikes from the wiring harness in automotive environments.
Route the ICSP clock and data lines (PGEC1/PGED1) with no more than 15 cm total trace length and avoid running them parallel to switching power or CAN lines. Keep an unobstructed path from the programming header to the MCU pins to support field firmware updates. The 28-SOIC package is wide-body, so leave room for a 0.1" header footprint on a PCB edge.
Use twisted-pair or shielded cable for the CANH/CANL lines routed through the ECAN module to comply with ISO 11898-2. Place a 120 Ω termination resistor at each end of the bus, and add common-mode chokes if the harness exceeds 30 cm. The ECAN peripheral requires MCU firmware to configure the CAN timing parameters to match the desired baud rate (e.g., 500 kbps).
