PIC24EP256GP204T-I/MV - 70 MIPS 256KB Flash 16-bit MCU | Microchip
MPN: PIC24EP256GP204T-I/MV ✓ Hoạt độngPIC24EP256GP204T-I/MV Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and configurable peripherals. Within the broader semiconductor taxonomy, an MCU belongs to the class of microcontrollers -> embedded processors -> digital ICs. The 16-bit PIC24E/PIC24EP architecture sits between 8-bit PIC16/PIC18 devices and 32-bit PIC32 devices, offering deterministic interrupt latency, a 16-element working register array, and DSP-friendly instructions (MAC, repeat, zero-overhead looping) at clock rates up to 70 MIPS.
Key features of the PIC24EP256GP204T-I/MV include 256 KB (85.5K x 24) of self-programmable Flash with ECC, 32 KB SRAM, integrated op-amps front-ending the ADC, a 12-bit ADC with up to 500 ksps throughput, motor-control PWMs with dedicated time bases, USB 2.0 full-speed On-The-Go, CAN, and flexible communication (UART/SPI/I2C). The 70 MIPS core executes most instructions in one cycle, and the device operates from 3.0 V to 3.6 V with industrial-grade -40 °C to +85 °C temperature range. The compact 6x6 mm UQFN-48 footprint suits high-density PCBs in space-constrained designs.
Typical applications include industrial motor control (BLDC, PMSM, stepper), digital power conversion, LED lighting drivers, USB peripherals, automotive body controllers, and medical instrumentation where the integrated op-amps, CTMU for capacitive touch or time-of-flight, and PTG for autonomous peripheral sequencing reduce external component count. When designing, allocate decoupling capacitors close to every VDDCORE/VDD pin pair and follow Microchip's analog-ground partitioning guidance to fully exploit the 12-bit ADC noise floor.

Ứng dụng tiêu biểu
PIC24EP256GP204T-I/MV phù hợp cho 6 Áp dụngs: Brushless DC (BLDC) Motor Control, Industrial Digital Power Conversion, USB HID/CDC Peripheral Devices, Automotive Body Electronics, Capacitive Touch & CTMU Sensing, Medical Instrumentation Front-End.
Brushless DC (BLDC) Motor Control
The PIC24EP256GP204T-I/MV fits BLDC and PMSM motor control because of its 70 MIPS core executing FOC inner loops within 14 µs, plus dedicated motor-control PWMs with 7.5 ns edge resolution and a 500 ksps 12-bit ADC. The integrated op-amps directly condition phase-current backspace as resistor voltages before ADC sampling, removing external amplifiers. The 256 KB Flash hosts state machines, sensorless observer code and diagnostic libraries, while 32 KB SRAM supports real-time logging. The 6x6 mm UQFN-48 footprint suits compact inverter PCBs.
Được đề xuất
Industrial Digital Power Conversion
The PIC24EP256GP204T-I/MV suits digital PFC, LLC and buck-boost converters because of its 70 MIPS throughput and high-resolution PWM (1.04 ns at 60 MHz peripheral clock). The 12-bit ADC samples at 500 ksps with internal op-amps, closing voltage and current loops fast enough for kW-class converters. The PTG (Peripheral Trigger Generator) sequences ADC-PWM events autonomously, offloading the CPU and tightening loop latency below 1 µs. USB and CAN enable factory-commissioned firmware updates on field-deployed power supplies.
Được đề xuất
USB HID/CDC Peripheral Devices
The PIC24EP256GP204T-I/MV integrates a USB 2.0 full-speed On-The-Go controller with internal transceiver and 1 KB endpoint RAM, eliminating the need for external PHY chips. With 70 MIPS throughput and 256 KB Flash, it can run USB stacks plus application logic (HID, CDC, MSD or composite) without external memory. DMA channels offload endpoint transfers from the CPU, freeing cycles for protocol processing. The 6x6 mm UQFN-48 package fits slim dongles and handheld instruments.
Được đề xuất
Automotive Body Electronics
The PIC24EP256GP204T-I/MV (industrial grade) is widely used in non-safety automotive body modules such as HVAC controls, instrument clusters, lighting drivers and LIN/CAN gateway nodes. Its CAN module and multiple UARTs handle body-network traffic, while the 12-bit ADC reads sensor inputs. For AEC-Q100-qualified variants in the same 48-pin UQFN, choose the PIC24EP256GP204-E/MV with extended -40 °C to +125 °C range. The 32 KB SRAM supports large CAN message buffers and diagnostic logging.
Được đề xuất
Capacitive Touch & CTMU Sensing
The PIC24EP256GP204T-I/MV integrates the Charge Time Measurement Unit (CTMU), which with the 12-bit ADC measures capacitance changes for capacitive touch buttons, sliders, and proximity sensing without dedicated touch ICs. The PTG sequences ADC-CTMU captures autonomously for low-power wake-on-touch operation. Designers can build 16+ touch channels within the 48-pin budget. The 256 KB Flash comfortably stores touch algorithms, gesture libraries and IO-Link/CAN reporting stacks.
Được đề xuất
Medical Instrumentation Front-End
The PIC24EP256GP204T-I/MV targets low-power medical instruments such as blood-pressure monitors, pulse oximeters, glucose meters and portable diagnostic aids. Its 12-bit ADC with internal op-amps directly digitizes sensor outputs from photodiodes or strain-gauge bridges, while USB OTG enables data transfer to PCs. The 70 MIPS core runs DSP filters for heart-rate extraction and SpO2 algorithms. The 48-pin UQFN-48 keeps PCB area minimal for handheld form factors meeting IEC 60601-1 EMI margins.

Ghi chú thiết kế
The UQFN-48 package requires a continuous ground plane beneath the exposed thermal pad (EP). Connect EP directly to the VSS plane with at least 8 thermal vias (0.3 mm drill, 0.6 mm pitch) to meet the 31.6 °C/W theta_JA specification. Place decoupling capacitors (100 nF X7R plus 4.7 µF tantalum) within 2 mm of every VDD/VDDCORE/AVDD pair, and keep analog ground (AVSS) isolated from noisy digital returns by a single-point bridge.
VDDCORE is generated internally from VDD via an on-chip 1.8 V regulator; the VCAP pin requires a 4.7 µF low-ESR ceramic to ground. Estimated: total VDD current at 70 MIPS is about 65 mA with all peripherals active. Add a 10 µF bulk capacitor near the VDD pin to handle USB inrush current (suspended device attach can draw up to 100 mA spikes) and avoid power-rail sag.
The 12-bit ADC achieves 500 ksps throughput only when the analog and digital ground returns are kept separate and the AVDD pin is filtered with a 10 Ω ferrite plus 100 nF + 10 µF capacitors. Route analog traces (AN0-AN3) away from switching PWM lines and the USB DP/DM differential pair, and use a guard ring around the analog input pins to minimize charge injection. Reference the ADC from an external 2.5 V source if absolute accuracy below ±2 LSB is required.
Do not leave the MCLR pin floating; tie it to VDD through a 10 kΩ pull-up or a manual reset network per Microchip app note AN786. Avoid using the internal FRC at temperatures below 0 °C without enabling the PLL lock to an external crystal, as FRC accuracy degrades to ±5% over industrial range. When programming Flash, the NVMSADSK register must be configured before the write - omitting it causes silent write failures.
Keep the USB DP/DM differential pair matched to 90 Ω ±10%, with maximum trace length of 50 mm and no vias. Reference the oscilloscope probe ground spring (not pigtail) when measuring USB eye diagram. Place the 12 MHz crystal within 5 mm of OSC1/OSC2 with a grounded copper guard ring to avoid radiated emissions failing FCC Class B at 168 MHz (third harmonic of 56 MHz internal clock).
