PIC24EP256GP204-I/MV Descripción general
Key features include 256 KB of Flash program memory (85.5K x 24 words), 32 KB of SRAM, an integrated 10/12-bit ADC with up to 1.1 Msps sample rate, dual operational amplifiers, dual comparators, and a CTMU (Charge Time Measurement Unit) for touch and capacitive sensing. The device also integrates the Peripheral Trigger Generator (PTG), which coordinates complex peripheral timing without CPU intervention - a defining feature of the PIC24EP family.
The PIC24E architecture combines a modified Harvard CPU with a five-stage pipeline, single-cycle MAC for DSP operations, and a wide 16-bit instruction set optimized for C-code density. The integrated op-amps and comparators eliminate external analog front-end components in signal-conditioning designs, while the CTMU enables cost-effective touch interfaces.
Typical applications include industrial motor control (BLDC, PMSM, stepper), digital power conversion (PFC, LLC, full-bridge), advanced sensor interfaces, LED lighting controllers, and low-cost audio processing. The 70 MIPS headroom and DSP capability allow closed-loop control loops in software, reducing BOM and time-to-market.
When designing with this part, ensure the UQFN-48 thermal pad is soldered to a sufficiently large ground copper pour for heat dissipation. Configure the JTAG/ICSP programming interface using any PGECx/PGEDx pair, but always as a matched pair per Microchip ICSP guidelines. The PTG module is a powerful but underused resource that can offload complex peripheral sequencing.

Aplicaciones típicas
PIC24EP256GP204-I/MV es adecuado para 6 aplicacións: BLDC / PMSM Motor Control, Digital Power Conversion (PFC, LLC, Full-Bridge), Industrial Sensor Signal Conditioning, LED Lighting Controllers and Drivers, Capacitive Touch HMI Interfaces, Low-Cost Audio Processing and Effects.
BLDC / PMSM Motor Control
The PIC24EP256GP204-I/MV drives brushless DC and permanent-magnet synchronous motors in 1-3 HP industrial and appliance applications. Its 70 MIPS core, integrated op-amps for current sensing, and high-resolution PWM modules enable field-oriented control (FOC) loops at 20-50 kHz switching frequency. The CTMU provides back-EMF zero-crossing detection for sensorless trapezoidal commutation, while the PTG coordinates ADC sampling aligned to PWM edges - critical for accurate current measurement. Engineers typically pair this MCU with gate drivers such as the MCP8024 and use the 32 KB SRAM for field-oriented state estimators without external memory. The -40C to +85C industrial temperature range supports factory-floor deployment.
Recomendado
Digital Power Conversion (PFC, LLC, Full-Bridge)
The PIC24EP256GP204-I/MV executes digital power control loops for PFC, LLC resonant, and phase-shift full-bridge converters at 100-500 kHz switching frequencies. The single-cycle MAC engine computes PID + feed-forward control laws in under 1 us, while the PTG synchronizes ADC sampling to PWM edges for accurate Vin/Vout sensing. The 256 KB Flash stores lookup tables for nonlinear control and adaptive dead-time compensation. The 1.1 Msps ADC captures voltage and current waveforms with sub-microsecond latency. Compared to fixed-frequency DSPs, the PIC24EP offers lower cost with adequate performance for sub-kW converters used in LED drivers, server PSUs, and EV charging modules.
Recomendado
Industrial Sensor Signal Conditioning
The PIC24EP256GP204-I/MV integrates two operational amplifiers, two comparators, and a 12-bit ADC on-chip, eliminating external analog front-end components in 4-20 mA loop sensors, RTD conditioning, and bridge sensor interfaces. The internal op-amps configured as instrumentation amplifiers can directly read load-cell bridge outputs with 0.1% accuracy. The CTMU measures capacitance for proximity and level sensing in industrial tanks. The 256 KB Flash supports complex calibration routines and linearization tables, while 32 KB SRAM buffers raw sensor data for FFT and statistical analysis. The -40C to +85C operating range suits factory and outdoor sensor installations.
Recomendado
LED Lighting Controllers and Drivers
The PIC24EP256GP204-I/MV manages multi-channel LED drivers in architectural, horticultural, and stage lighting products. Its high-speed PWM (up to 16-bit resolution) enables smooth dimming without flicker, while the 70 MIPS core runs color-mixing algorithms and DMX/RDM protocol stacks simultaneously. The CTMU provides touch-based intensity control, and the integrated op-amps drive current-sense feedback for closed-loop LED current regulation. The 32 KB SRAM stores lighting scenes and animation sequences. The wide operating voltage range (3.0-3.6V) is compatible with standard 3.3V LED driver rails. Total BOM reduction is significant versus discrete MCU + LED driver IC designs.
Recomendado
Capacitive Touch HMI Interfaces
The PIC24EP256GP204-I/MV implements up to 32 capacitive touch buttons or sliders using the integrated CTMU (Charge Time Measurement Unit) and the on-chip ADC. This eliminates dedicated touch ICs in appliances, industrial control panels, and consumer electronics, reducing BOM by 30-50%. The 256 KB Flash supports Microchip's mTouch library with gesture recognition and water-rejection algorithms. The 70 MIPS throughput scans 32 channels in under 5 ms with 12-bit resolution. UART, I2C, and SPI interfaces connect to host displays or main controllers. The -40C to +85C temperature range suits outdoor and appliance environments.
Recomendado
Low-Cost Audio Processing and Effects
The PIC24EP256GP204-I/MV processes audio at 16-48 kHz sample rates using the single-cycle MAC engine for real-time filters, equalizers, and effects. The DSP extensions execute biquad filters in 4 instruction cycles, enabling 8-band parametric EQ or reverb algorithms at 48 kHz with under 30% CPU loading. The 12-bit DAC (or PWM-driven external DAC) outputs processed audio, while I2S or SPI interfaces connect to external codecs. The 256 KB Flash stores multiple preset banks and effects chains. This MCU is a cost-effective audio solution for musical instruments, consumer audio, and intercom systems where DSP performance and BOM cost both matter.

Diferenciadores clave

- Integrated analog peripherals reduce BOM (frente a PIC24EP128MC204-E/MV)
- Industrial temperature range with -I grade (frente a PIC24EP256GP204-E/MV)
- Single-cycle MAC DSP at 70 MIPS (frente a dsPIC33EP256GP504-I/MV)
Notas de diseño
The UQFN-48 package has an exposed thermal pad on the underside that must be soldered to a ground copper pour for proper thermal dissipation. Without adequate copper (recommended at least 1 square inch of 2oz copper), junction temperature can rise significantly under high CPU loading at 70 MIPS. Estimated: at ambient 25C, 70 MIPS, 3.3V VDD, total power dissipation is approximately 90 mW with theta_JA around 35 C/W on a 4-layer PCB with thermal vias - yielding a junction temperature rise of about 3-5C above ambient, well within the 125C limit.
Decouple each VDD/VSS pin pair with a 100 nF ceramic capacitor placed within 3 mm of the pin, plus a single 4.7 uF bulk capacitor on each VDD rail. The analog supply AVDD requires an additional ferrite bead and 10 uF + 100 nF decoupling for ADC noise immunity. Place the programming header (PGECx/PGEDx/MCLR) on the board edge or test-point accessible area for ICSP. Route the crystal traces short and symmetric to minimize EMI per Microchip OSC design guidelines.
Do not confuse the MV (UQFN-48) suffix with ML (QFN-44) or PT (TQFP-44) - they are not pin-compatible and require different PCB footprints. The PIC24EP256GP204 has dual ICSP programming pairs (PGEC1/PGED1 and PGEC2/PGED2); you must use them as matched pairs per Microchip ICSP specification. Avoid leaving unused I/O pins floating - configure as outputs or inputs with internal pull-ups to minimize current consumption and EMI. The PTG module is a powerful but underused resource - it can sequence complex peripheral operations without CPU intervention, freeing the core for DSP or control loops.
