PIC24EP32GP202-I/SS Visão geral
A 16-bit microcontroller is a programmable computing device that uses a 16-bit wide data path and instruction set, sitting architecturally between 8-bit MCUs and 32-bit ARM Cortex-M parts. The PIC24EP family is part of the broader dsPIC33/PIC24E digital signal controller (DSC) lineage, optimized for deterministic real-time control with single-cycle MAC instructions, hardware multipliers, and zero-overhead looping. In the system hierarchy, MCUs belong to embedded processors, which sit within the wider category of power management and control semiconductors.
Key features of the PIC24EP32GP202 include up to 16 analog input channels with 10-bit and 12-bit ADC options, multiple UART/SPI/I2C peripherals, enhanced PWM modules, and integrated peripherals such as the Charge Time Measurement Unit (CTMU), operational amplifiers, and the Peripheral Trigger Generator (PTG) for offloading CPU-driven sequencing. The 70 MIPS core executes most instructions in one cycle, and code density is improved by Microchip's 24-bit instruction word.
Typical applications include industrial motor control (BLDC, PMSM, stepper), digital power conversion, LED lighting drivers, sensor signal conditioning with on-chip op-amps, and general-purpose embedded control for HVAC, appliances, and factory automation. The integrated peripherals allow designers to replace several external analog components.
When designing with this MCU, pay attention to the 28-pin SSOP variant's pinout limits - some peripherals share pins and require careful PPS (Peripheral Pin Select) configuration. The 3.3 V core voltage precludes direct 5 V GPIO; level shifters are needed when interfacing to legacy 5 V logic.

Aplicações típicas
PIC24EP32GP202-I/SS é adequado para 6 aplicaçãos: Industrial Motor Control, Digital Power Conversion (DC-DC, LED Drivers), Sensor Signal Conditioning and IoT Edge Nodes, HVAC and Appliance Control, Automotive Body and Lighting Modules, Test, Measurement, and Data Acquisition.
Industrial Motor Control
The PIC24EP32GP202-I/SS is well suited for low- to mid-performance industrial motor control tasks such as small BLDC fans, stepper drives, brushed DC motors, and pump controllers. With 70 MIPS performance and enhanced PWM modules, it can execute trapezoidal commutation at moderate switching frequencies (20-40 kHz). The 10/12-bit ADC and integrated op-amps (where present) allow direct current sensing via shunt resistors, eliminating the need for external current-sense amplifiers. For higher-performance FOC or sinusoidal control, the related PIC24EP32MC202 adds dedicated motor-control peripherals, but the GP202 remains an attractive cost option for non-servo applications.
Recomendado
Digital Power Conversion (DC-DC, LED Drivers)
The PIC24EP32GP202's 70 MIPS core and high-resolution PWM make it a capable controller for digital DC-DC converters and LED lighting drivers. The 10-bit ADC with up to 16 channels enables closed-loop voltage and current sensing, while the high-speed PWM supports 500 kHz+ switching frequencies for compact power supply designs. Compared with analog controllers, the PIC24EP allows adaptive algorithms such as valley-mode switching and dynamic overcurrent protection. The integrated op-amps (on select variants) provide current-sense conditioning directly, reducing BOM cost.
Recomendado
Sensor Signal Conditioning and IoT Edge Nodes
For IoT edge nodes and sensor interface boards, the PIC24EP32GP202-I/SS offers 16 ADC channels, multiple UART/SPI/I2C peripherals, and ample Flash for sensor-fusion algorithms. The 70 MIPS core handles modest DSP tasks like digital filtering on temperature, pressure, or flow sensor data. Combined with the CTMU for capacitive touch sensing or the PTG for hardware-triggered sequencing, the part can run deterministic sensor acquisition with minimal CPU intervention. Its 3.3 V operation and low-power sleep modes make it a good fit for battery-backed wireless sensor nodes.
Recomendado
HVAC and Appliance Control
White-goods and HVAC systems benefit from the PIC24EP32GP202's combination of peripherals and 32 KB Flash. It can drive multiple relays via PWM, read thermistor temperature sensors via ADC, run user-interface keypads, and communicate with displays via SPI or I2C. The CTMU enables touch-key replacement for mechanical buttons in modern appliance front panels. Industrial temperature grade (-40 to +85 °C) supports under-cabinet and outdoor equipment enclosures. Compared with 8-bit alternatives, the 16-bit core simplifies math for PID loops and time-proportional control.
Recomendado
Automotive Body and Lighting Modules
While the PIC24EP32GP202-I/SS itself is industrial-grade, its part-number sibling PIC24EP32GP202-E/SS supports the extended -40 to +125 °C automotive temperature range and is AEC-Q100 qualified. It is commonly used in body controllers, lighting modules (interior ambient, LED matrix drivers), and accessory control units where 70 MIPS, LIN bus capability, and PWM dimming are required. AEC-Q100 qualification is required for under-hood and cabin-mounted modules - confirm the exact automotive grade variant before designing.
Recomendado
Test, Measurement, and Data Acquisition
The PIC24EP32GP202's 16 ADC channels, ample Flash for calibration tables, and DSP-friendly core make it a solid fit for handheld test instruments, multi-channel data loggers, and educational lab equipment. The 70 MIPS core can execute FIR filters in real time, and the multiple UART/SPI ports allow communication with display modules or USB-to-UART bridges. For higher sample rates, the PIC24EP128 family or dsPIC33EP variants provide more RAM for buffer-based acquisition.

Notas de projeto
The PIC24EP32GP202 operates from a single 3.0-3.6 V supply. Place a 10 µF tantalum or ceramic bulk capacitor on VDD plus a 0.1 µF ceramic decoupling cap within 3 mm of each VDD pin. Use Microchip's MCP1700-3302E 3.3 V LDO (250 mA, 1.6 µA quiescent) for low-cost regulation from a 5 V rail. Estimated: at 70 MIPS active with all peripherals on, IDD is approximately 30-40 mA, so the 250 mA MCP1700 headroom is comfortable.
Route the ICSP programming pins (PGC/PGD) directly to an in-circuit programming header; Microchip programmers (PICkit 3, MPLAB SNAP, ICD 4) require these for Flash debug. Keep the MCLR reset trace short and add the typical 10 kΩ pull-up to VDD. For SSOP-28, allow clearance for the SOIC-style programming clip if used in production.
Do not exceed 3.6 V on any I/O - the PIC24EP family is NOT 5 V tolerant. When interfacing to 5 V sensors or actuators, use a level translator such as TI's TXS0108E or a discrete MOSFET/resistor divider. Confirmed by Microchip datasheet: absolute maximum VDD is 4.0 V and any pin above this rating can cause permanent damage. Also note that PPS (Peripheral Pin Select) configuration must be unlocked in the __builtin_write_OSCCONL sequence to take effect; forgetting the unlock sequence is a common development trap.
At 70 MIPS full activity the PIC24EP32GP202 typically dissipates around 100-150 mW. The 28-SSOP thermal resistance (θJA) is approximately 100 °C/W on a 1 oz copper JEDEC test board, giving ~10-15 °C rise above ambient. No heatsink is required for normal operation, but ensure adequate copper pour on VDD/VSS pins to provide thermal spreading. Estimated: at +85 °C ambient and 150 mW dissipation, junction temperature stays well below the +150 °C maximum.
Informações de conformidade
