PIC24EP64MC202-I/SS - 16-Bit 70 MIPS 64KB Flash Motor MCU | Microchip
The Microchip PIC24EP64MC202-I/SS is a 16-bit PIC24EP motor-control microcontroller delivering 70 MIPS of CPU performance at up to 60 MHz, integrating 64 KB (22K x 24) of Flash program memory and 8 KB of SRAM in a 28-pin SSOP package. It targets high-performance, precision motor-control systems and combines a high-speed PWM module with on-chip op amps, comparators, and a QEI interface that are essential for field-oriented control (FOC) of three-phase PMSM, BLDC, and AC induction drives.
An MCU (microcontroller unit) is a single-chip computer integrating a CPU core, program memory (typically Flash), data memory (SRAM), and a rich set of on-chip peripherals such as timers, ADC, communication controllers, and GPIO. The PIC24EP family extends this concept into the digital-signal-control (DSC) segment with a 16-bit modified Harvard architecture and a single-cycle MAC engine, bridging 8-bit PIC microcontrollers and 32-bit ARM Cortex parts. Within Microchip's taxonomy, the dsPIC33/PIC24EP "MC" family is the motor-control-optimized derivative of the PIC24EP DSC line, distinguished by high-resolution PWM, fast ADC, QEI for shaft feedback, and analog comparators that protect the power stage.
Key features include three pairs of complementary PWM outputs (6 PWM channels) with 1.04 ns resolution, a 10-bit ADC with up to 500 ksps conversion, two on-chip operational amplifiers usable as current-sense buffers, three high-speed comparators for cycle-by-cycle overcurrent protection, a Quadrature Encoder Interface (QEI), and a Peripheral Trigger Generator (PTG). The device operates from 3.0 V to 3.6 V across an industrial temperature range of -40 C to +85 C and supports USB, I2C, SPI, and UART interfaces for supervisory or HMI connectivity.
Typical applications include sensorless and sensored BLDC/PMSM motor drives (fans, pumps, drones, e-bikes), appliance compressors, small industrial servo drives, robotics, and power tools. Two op-amps on-die directly sense shunt resistors in a three-phase inverter, eliminating external amplifiers and shrinking BOM. The high-resolution PWM and 10-bit ADC in 1 MSPS sampling capability simplify current-loop tuning.
When designing with this part, place decoupling capacitors within 3 mm of each VDD/VSS pin pair and route the analog AVdd/AVss pair with a separate ground island tied to digital ground at a single point. Program Flash via ICSP or the device's JTAG boundary-scan interface using MPLAB X IDE and the XC16 compiler.
