PIC24EP64GP202T-I/SS Overview
A 16-bit microcontroller (MCU) is a programmable logic device with a 16-bit datapath, registers, and arithmetic logic unit, falling within the broader categories of embedded controller -> microcontroller -> integrated circuit -> semiconductor. The PIC24E family sits between 8-bit PIC MCUs and 32-bit PIC32 devices in the Microchip portfolio, providing higher code density and DSP-like instructions while retaining the familiar MPLAB X toolchain and peripheral library. The PIC24EP64GP202T-I/SS belongs to the "GP" general-purpose sub-family with motor-control friendly peripherals absent and lower pin count, while the "MC" parts add high-speed PWM hardware. Key features are 1.1 Msps 10-bit or 500 ksps 12-bit configurable ADC with up to six analog inputs on 28-pin variants, three on-chip op-amps and four comparators, Peripheral Trigger Generator (PTG), and up to 21 I/O pins.
The PIC24E core uses a modified Harvard architecture with a 16-bit instruction word and 24-bit instruction set extensions, supporting fractional arithmetic and DSP-style multiply instructions useful for motor control and digital filtering. Hardware-level DMA is not present on this 28-pin variant; data movement is handled by the CPU and peripherals. Typical applications include industrial sensor conditioning, low-cost motor control (BLDC, stepper) where the 70 MIPS headroom and CTMU enable capacitive touch sensing, portable instrumentation, and general-purpose 3.3 V embedded control. According to the Microchip datasheet, designers should observe the 3.0 V minimum supply and provide bulk decoupling near the VDDCORE pin to limit inrush during PLL start-up. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, helping procurement and engineering teams make informed second-source decisions.

Typical Applications
PIC24EP64GP202T-I/SS is suitable for 7 applications: Industrial Sensor Signal Conditioning, Capacitive Touch User Interface, Low-Cost 3.3V Embedded Control, Portable Instrumentation and Data Loggers, LED Lighting and Dimming Control, Automotive Body Electronics (Non-Safety), Educational and Prototyping Platforms.
Industrial Sensor Signal Conditioning
The PIC24EP64GP202T-I/SS is well-suited to industrial sensor conditioning thanks to its 3 on-chip op-amps and 4 comparators, which reduce the external analog chain. With 70 MIPS headroom, the MCU can run digital filtering on the ADC samples while the CTMU supports resistive or capacitive sensor excitation. The 12-bit 500 ksps ADC delivers adequate resolution for 4-20 mA loop and bridge-sensor front-ends, while the 3.0-3.6 V supply matches industrial 3.3 V rails. Placed near the sensor with proper grounding and a separate analog VDDCORE pin decoupling network, the part outperforms discrete op-amp + 8-bit MCU designs at lower board cost.
Recommended
Capacitive Touch User Interface
The CTMU on the PIC24EP64GP202T-I/SS enables reliable capacitive touch sensing without an external charge pump IC, supporting button, slider, and wheel implementations. With 70 MIPS and 8 KB of SRAM, the MCU can debounce and post-process the CTMU readings while still servicing the host UART and indicator LEDs. The 28-SSOP package exposes enough I/O for 8-12 touch channels, and the industrial -40C to +85C range suits appliance and white-goods UI panels. Compared with a dedicated touch IC, the integrated approach cuts BOM cost while keeping firmware flexibility via MPLAB X IDE.
Recommended
Low-Cost 3.3V Embedded Control
General-purpose 3.3 V embedded control is the core use case for the PIC24EP64GP202T-I/SS, where 64 KB flash and 8 KB SRAM are ample for state machines, protocol stacks (Modbus, LIN), and display driving. The 70 MIPS core delivers 36 percent more throughput than a PIC24FJ64 part at the same clock, accelerating interrupt response and easing firmware timing margins. The 28-SSOP footprint drops onto existing PIC24FJ28-pin boards, enabling in-place upgrades. Place 10 uF and 0.1 uF decoupling near VDD and route the analog ground separately for mixed-signal boards.
Recommended
Portable Instrumentation and Data Loggers
Portable data loggers benefit from the PIC24EP64GP202T-I/SS because its low active power and 70 MIPS execution let it sample sensors and crunch statistics on a small battery budget. The 10-bit 1.1 Msps ADC captures fast transients, while 64 KB flash accommodates local lookup tables and calibration coefficients. The 28-SSOP footprint is small enough for handheld enclosures, and the -40C to +85C industrial range supports field deployment. Pair with an external EEPROM or SD card over SPI for non-volatile storage and stream summary data over UART when docked.
Recommended
LED Lighting and Dimming Control
The PIC24EP64GP202T-I/SS can drive multi-channel LED fixtures via its PWM and PTG peripherals, which generate accurate timing sequences without CPU overhead. With 3 comparators on-chip, current sensing for constant-current regulation is straightforward, eliminating the need for a separate analog controller. The 64 KB flash stores fade tables and color-mixing curves, and the 3.0-3.6 V supply rails match constant-current driver ICs. Compared with 8-bit PIC16 alternatives, the 16-bit core simplifies logarithmic dimming math via native fractional multiplication.
Recommended
Automotive Body Electronics (Non-Safety)
For non-safety automotive body electronics such as interior lighting controllers, seat heaters, and mirror adjusters, the PIC24EP64GP202T-I/SS provides industrial-grade reliability within a 3.3 V rail. While it lacks the AEC-Q100 qualification reserved for the dedicated automotive grade parts, it is widely used in body-control prototypes and aftermarket modules where -40C to +85C is sufficient. The 28-SSOP footprint fits behind dashboard switch panels and the LIN-compatible UART simplifies in-vehicle networking. Use external TVS diodes on supply and I/O lines for load-dump immunity.
Recommended
Educational and Prototyping Platforms
The PIC24EP64GP202T-I/SS is a popular choice for university embedded courses and rapid prototypes because the MPLAB X IDE, XC16 compiler, and PICkit 4 programmer are free and well-documented. The 64 KB flash and 8 KB SRAM comfortably fit lab projects such as PID loops, FFT demos, and small RTOS implementations. The 28-SSOP package breaks out enough peripherals for ADC, PWM, UART, SPI, and I2C exploration. Compared with an 8-bit baseline, the 16-bit core teaches DSP-style fractional arithmetic and Harvard architecture concepts in the same semester.

- DSP upgrade path with same pinout (vs dsPIC33EP64MC202-I/SS)
Design Notes
Place a 10 uF bulk capacitor plus a 0.1 uF ceramic capacitor as close to the VDD pin as possible to suppress inrush during clock PLL lock. The PIC24E core draws higher transient currents when the PLL switches from FRC to the crystal reference. Separating analog and digital ground returns into a star at the VSS pin reduces ADC noise by 1-2 LSB.
Route the analog C input pins (AN0-AN5) as short as practical and keep them away from the PWM or digital switching lines to limit crosstalk. The 28-SSOP package has limited internal ground; add a ground pour under the IC and stitch vias around the perimeter. Place the crystal within 5 mm of OSCI/OSCO with a guard trace tied to ground.
Estimated: programming voltage on MCLR must reach 13V nominal; using a 3.3V-only debugger fails to enter ICSP mode. The "/SS" suffix denotes the SSOP-28 package and not the standard SOIC-28, so verify the PCB land pattern supports the 0.65 mm pitch before ordering. Do not exceed 3.6 V on any pin - the analog front-end lacks 5 V tolerance.
At 70 MIPS continuous execution with all peripherals active, the PIC24EP64GP202T-I/SS draws approximately 50 mA, dissipating roughly 165 mW at 3.3 V. The 28-SSOP package has adequate copper area on most boards to stay below 70C junction at room temperature, but enclosed fixtures may require derating. Estimated values based on typical current consumption.
