PIC24EP128MC202T-I/SS 개요
A 16-bit microcontroller (MCU) is a single-chip computer that integrates a 16-bit CPU core, program memory, data RAM, and peripherals such as timers, ADCs, communication interfaces, and PWM modules. The PIC24EP family belongs to the broader dsPIC33 / PIC24E lineage of Microchip's high-performance 16-bit controllers, sitting architecturally between 8-bit PIC16/PIC18 MCUs and 32-bit ARM Cortex-M devices. This hierarchy makes the PIC24EP128MC202 ideal for demanding real-time control tasks that exceed 8-bit capability but do not justify the cost or power of a 32-bit MCU.
Key features include three 16-bit timers, up to six PWM channels with high-speed PWM (up to 1 ns PWM resolution), a 10/12-bit ADC with up to 1.1 Msps conversion rate, four op amps and three comparators optimized for current/voltage sensing, plus communication peripherals including UART, SPI, I2C, and ECAN. The integrated motor-control PWM module supports complementary outputs with programmable dead time, making the device particularly well-suited to driving three-phase motor inverter stages.
The device uses a 5-stage pipeline modified Harvard architecture with a 16-bit data path and 24-bit instruction width, providing high code density and deterministic interrupt response. An on-chip 8 MHz internal oscillator with PLL supports system clock scaling up to 70 MIPS without an external crystal, reducing BOM cost. The peripheral trigger generator (PTG) and DMA controller offload CPU overhead for high-speed data movement.
Typical applications include brushless DC (BLDC) motor control, permanent magnet synchronous motor (PMSM) field-oriented control (FOC), industrial servo drives, low-power fan/pump controllers, and home appliances with sensorless or sensored motor feedback. The integrated op amps and comparators allow direct current-shunt monitoring and back-EMF sensing without external analog components.
When designing with the PIC24EP128MC202T-I/SS, note that the SSOP-28 footprint has limited thermal dissipation, so high-current PWM outputs should drive gate-driver ICs rather than power switches directly. The MPLAB X IDE with the MPLAB XC16 compiler and the MPLAB Code Configurator (MCC) plugin is the recommended toolchain for peripheral setup and motor-control application development.

일반적인 애플리케이션
PIC24EP128MC202T-I/SS 적합 용도: 3 애플리케이션s: Brushless DC (BLDC) Motor Control, Field-Oriented Control (FOC) of PMSM Motors, Industrial Servo Drive Control.
Brushless DC (BLDC) Motor Control
The PIC24EP128MC202T-I/SS is purpose-built for BLDC motor control with integrated gate-driver-friendly PWM outputs and current-sense op amps. Its 70 MIPS core runs sensorless or sensored commutation at 20-40 kHz PWM, while the 1.1 Msps ADC samples two phase currents and DC-bus voltage synchronously with the PWM reload for jitter-free measurement. The 4 op amps interface directly to low-side current shunts without external instrumentation amplifiers, cutting BOM cost. The Microchip AN1160 sensorless BEMF application note ships reference firmware for this MCU, accelerating time-to-market. Use the dsPIC33EP variant if hardware DSP is required for advanced filter routines.

Field-Oriented Control (FOC) of PMSM Motors
The PIC24EP128MC202T-I/SS supports field-oriented control of permanent magnet synchronous motors via its 16KB RAM and 70 MIPS throughput. The MCU executes Clarke/Park transforms, SVPWM modulation, and PI current loops within typical 10-20 kHz control rates, leaving headroom for speed/torque loops and communication. The 3 comparators handle fast over-current protection by triggering a hardware PWM shutdown independent of CPU latency. Reference FOC firmware is provided in Microchip AN1078. For applications demanding higher control rates or hardware DSP, step up to the dsPIC33EP128MC202 in the same SSOP-28 footprint.

Industrial Servo Drive Control
The PIC24EP128MC202T-I/SS fits industrial servo drive position loops where 16-bit control precision, ECAN communication, and deterministic interrupt response are required. Its peripheral trigger generator (PTG) synchronizes ADC sampling to PWM edges, ensuring consistent current-sampling points across load conditions. The ECAN peripheral enables multi-axis drives on a single CAN bus, while the UART supports RS-485 for legacy industrial networks. The industrial -40C to +85C temperature rating covers factory-floor enclosures, and the SSOP-28 package is footprint-compatible with the higher-pin-count PIC24EP256MC202 family for code migration.
