PIC24EP64GP202-I/MM - 16-Bit 70 MIPS MCU, 64KB Flash | Microchip
MPN: PIC24EP64GP202-I/MM ✓ Hoạt độngPIC24EP64GP202-I/MM Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (typically Flash), data RAM, and a rich set of peripherals on one silicon die. The PIC24EP family sits in Microchip's 16-bit DSC/MCU portfolio, hierarchically placed above 8-bit PIC16/PIC18 MCUs and below the 32-bit PIC32 families. This part is targeted at high-end general-purpose embedded designs that need more compute and analog performance than 8-bit MCUs but do not justify migrating to a 32-bit core.
Key features include a 12-bit ADC with up to 10/12 Msps sampling (family capability), dedicated op amps, a Charge Time Measurement Unit (CTMU) for touch and capacitive sensing, a Peripheral Trigger Generator (PTG) for hardware-event sequencing, and a 16-bit motor-control PWM peripheral, alongside USB 2.0 full-speed On-The-Go on related family members.
The architecture combines a 16-bit data path with 24-bit instructions, which improves code density relative to 32-bit cores and eases C compiler efficiency. Internal PLLs allow the core to run faster than the external crystal. The 28-QFN-S package includes a thermal pad for improved heat dissipation in industrial temperature ranges (-40 C to +85 C for this -I grade).
Typical applications include industrial control boards, sensor signal conditioning, USB peripherals, motor-control companion logic, and general-purpose 16-bit embedded platforms where analog integration (ADC, op amps, CTMU) reduces external component count.
When designing with this device, allocate ADC and op-amp pinout early and follow Microchip's analog-ground PCB guidelines (separate AGND/AVSS pour, decouple Vcap/Vddcore). The Peripheral Trigger Generator requires MPLAB X IDE plugin configuration, and op-amp input ranges must respect rail-to-rail limits.

Ứng dụng tiêu biểu
PIC24EP64GP202-I/MM phù hợp cho 6 Áp dụngs: Industrial Sensor Signal Conditioning, USB HID / CDC Peripherals, Motor Control Companion Logic, Capacitive Touch User Interface, Portable Medical / Health Monitoring, Power Conversion Digital Control.
Industrial Sensor Signal Conditioning
The PIC24EP64GP202-I/MM fits sensor signal conditioning because its integrated 10/12-bit ADC, two on-chip op amps, and CTMU remove the need for external analog front-end ICs on thermocouple, RTD, and bridge-pressure boards. Its 70 MIPS core runs linearization, calibration, and digital-filter loops in real time without off-loading to a DSP. Power consumption stays low enough for 4-20 mA loop-powered transmitters when the CPU idles between conversions.
Được đề xuất
USB HID / CDC Peripherals
The PIC24EP64GP202-I/MM integrates a USB 2.0 full-speed On-The-Go controller with internal transceiver, enabling HID, CDC, or vendor-class USB devices without an external PHY. The 70 MIPS core handles enumeration, descriptor parsing, and application protocol concurrently, while the 28-QFN-S 6x6 mm footprint suits compact dongles. Designers should follow the Microchip USB hardware checklist for VBUS, D+/D- trace impedance, and ferrite-bead placement.
Được đề xuất
Motor Control Companion Logic
For motor-control applications, the PIC24EP64GP202-I/MM provides 16-bit PWM, a 70 MIPS core for field-oriented control (FOC) loops, and fast ADC for back-EMF and current sensing. It pairs well with dedicated gate-driver or smart-power modules as a supervisory / communication controller in BLDC and PMSM designs. The CTMU simplifies key capacitive-touch user interfaces on the same PCB.
Được đề xuất
Capacitive Touch User Interface
The PIC24EP64GP202-I/MM features the Charge Time Measurement Unit (CTMU), which uses a constant current source and timer to measure capacitance changes on touch pads. This yields robust proximity and button sensing without dedicated touch ICs, with the 16-bit core handling debouncing, gesture recognition, and host-side protocol. The 28-Q-FN 6x6 mm footprint supports small appliance front-panel designs.
Được đề xuất
Portable Medical / Health Monitoring
Medical wearables and point-of-care devices benefit from the PIC24EP64GP202-I/MM's low-power sleep modes, on-chip op amps for analog front-end, and ADC for biosignal acquisition (pulse oximetry, ECG front ends). The CTMU supports capacitive proximity wake-up, reducing standby current. Operating temperature -40 C to +85 C covers most clinical and consumer-health environments.
Được đề xuất
Power Conversion Digital Control
The PIC24EP64GP202-I/MM is well suited to digital control of DC-DC converters, PFC stages, and digital LED drivers thanks to its high-resolution PWM, fast ADC, and 70 MIPS core. The Peripheral Trigger Generator (PTG) enables deterministic hardware-event sequencing for tight control loops without CPU intervention. The same 28-Q-FN 6x6 mm footprint allows compact power-supply daughter modules.

Ghi chú thiết kế
The 28-QFN-S package includes an exposed thermal pad on the underside that MUST be soldered to the ground plane for both electrical reference and thermal dissipation. Place a 4-6 via array (0.3 mm drill, 0.5 mm pitch) directly under the EP for low-impedance grounding and heat transfer. Use separate analog and digital ground pours joined at a single point near the IC, and decouple VDD/VSS pairs with 100 nF X7R ceramic capacitors placed as close as possible to the pins.
The PIC24EP64GP202-I/MM uses an on-chip voltage regulator that requires a low-ESR decoupling capacitor on VCAP (typically 10 uF X5R + 100 nF parallel) for stable core logic. Without this cap the regulator may oscillate or fail to start. VDD supply decoupling should combine bulk (1-10 uF) and high-frequency (100 nF) capacitors. If the application powers down and re-cycles VDD rapidly, allow POR release time before issuing the first instruction.
Analog signal traces (ADC inputs, op-amp inputs/outputs) must be kept short, shielded by an analog ground pour, and routed away from PWM and switching signals. The op-amp output impedance is sensitive to capacitive loads; keep output trace length under a few millimeters. Place the ADC reference voltage bypass cap within 5 mm of the AVss pin. Reference Microchip analog design guidelines for the PIC24E family.
The MCLR pin requires a 10 kohm pull-up to VDD for normal operation; floating MCLR prevents program execution. The PTG requires the Peripheral Trigger Generator plugin in MPLAB X IDE - omitting the plugin leaves PTG registers inaccessible. Clock-switching to the FRC must wait for the PLL lock bit before executing from the new clock source, otherwise instruction fetches may fail.
