MPN: PIC24EP32GP202T-I/SS ✓ AktifPIC24EP32GP202T-I/SS Ringkasan
A 16-bit MCU (microcontroller) is a single-chip computer integrating a CPU core, program memory (Flash), data memory (RAM), and a rich set of on-chip peripherals such as timers, communication interfaces, and analog modules. The PIC24EP family belongs to the broader dsPIC/PIC24 microcontroller hierarchy -> 16-bit MCU -> embedded MCU -> semiconductor. Compared with 8-bit MCUs, 16-bit cores provide higher throughput and more efficient C code density, while retaining deterministic real-time interrupt behavior that PIC microcontrollers are known for.
Key features of this part include a 70 MIPS modified Harvard CPU core, 32KB self-programmable Flash with ECC, 4KB SRAM, integrated op-amps, comparators, and a Peripheral Trigger Generator (PTG). The device supports up to 13 ADC channels with 10/12-bit resolution options (family feature), multiple UART/SPI/I2C peripherals, and PWM outputs. The CTMU (Charge Time Measurement Unit) enables touch sensing and precise time-of-flight measurements.
Technically, the PIC24EP32GP202 implements a 16-bit modified Harvard architecture with separate program and data buses, a 16 x 16-bit working register array, and DSP-friendly instructions. The 3.3V core supply (VDD) operates across 3.0-3.6V, with separate analog and digital supply pins for noise isolation, supporting high-performance ADC sampling alongside switching digital peripherals.
Typical applications include industrial control, motor control (PWM-driven), sensor signal conditioning using the integrated op-amps, USB/HID human-interface devices, and general-purpose embedded control. The internal analog front-end (op-amps + comparators + 12-bit ADC) makes the device particularly attractive for mixed-signal designs that previously required a dedicated analog IC.
When designing with this device, ensure decoupling on every VDD pin (100 nF + bulk), follow the datasheet's trace-width guidelines for the SSOP exposed pad (where applicable) and route the analog supply (AVDD) through a ferrite bead for noise-sensitive ADC measurements.

Catatan Desain
Estimated: total power consumption at 70 MIPS with all peripherals active is approximately 60-80 mW from a 3.3V supply. Place a 100 nF ceramic decoupling capacitor on every VDD/AVDD pin within 5 mm of the package, plus a single 4.7 uF bulk capacitor near the device. For noise-sensitive ADC measurements, route AVDD through a ferrite bead to isolate from VDD digital switching noise. The Microchip PIC24EP datasheet specifies maximum VDD ripple of 50 mV peak-to-peak for full ADC accuracy.
The 28-SSOP package has a theta_JA of approximately 80-100 C/W (estimated; varies with PCB copper area). At 80 mW dissipation, junction temperature rise above ambient is approximately 6-8 C, well within the industrial -40C to +85C range. For designs operating in enclosed housings without airflow, ensure at least 1 square inch of bottom-side copper to spread heat. The Microchip datasheet's thermal model assumes a 4-layer 2 oz copper test board.
The 28-SSOP package has 0.65 mm pitch - use 0.4 mm-wide traces between pads and at least 4 mil solder mask dam. Route analog signals (OA1IN+, OA1IN-, VREF+) on a separate inner layer away from digital switching traces. Keep the MCLR pull-up resistor within 5 mm of pin 1 and add a 100 nF cap to ground for noise immunity. The exposed pad (if any) on the SSOP variant is not electrically connected - it improves thermal performance only.
Common mistakes when designing with the PIC24EP32GP202T-I/SS: (1) failing to configure the op-amp enable bits in firmware - the op-amps are disabled by default to save power; (2) confusing VREF+ with AVDD - VREF+ is the ADC reference and may be driven separately or tied to AVDD; (3) leaving the JTAG/ICSP pins unbonded or floating - they must be pulled to known states for in-circuit programming. The Microchip datasheet errata list documents additional silicon revisions.
