PIC24EP256MC204-E/PT - 16-Bit 60 MIPS MCU 256KB Flash | Microchip
MPN: PIC24EP256MC204-E/PT ✓ AktifPIC24EP256MC204-E/PT Ringkasan
A 16-bit microcontroller (MCU) is a microprocessor that integrates a CPU core, program memory (Flash), data memory (RAM), and peripherals into a single IC. PIC24E MCUs use a modified Harvard RISC architecture with 16-bit instructions and 24-bit instructions for compact code. They belong to the broader category of embedded microcontrollers within power-aware semiconductor ICs used in motor control, industrial automation, and consumer electronics.
Key features include a 70 MIPS CPU performance, dual 40-bit accumulators, single-cycle MAC, hardware multiply/divide, integrated op-amps and 12-bit ADC with up to 500 ksps conversion rate, plus dedicated motor-control PWM with high-resolution edge placement. Communication peripherals cover UART, SPI, I2C, ECAN, and parallel ports for flexible system integration.
The PIC24EP256MC204-E integrates dedicated motor-control peripherals: high-speed PWM with 1.04 ns PWM resolution, quadrature encoder interface, and built-in operational amplifiers. The 60 MIPS core and DSP engine enable real-time closed-loop control algorithms (FOC, PID) without offloading to external DSPs, while the 256KB Flash supports substantial application code and self-programming for field updates.
Typical applications include 3-phase BLDC/PMSM motor drives for appliances, HVAC blower and compressor control, industrial servo control, ceiling fans, e-bike controllers, and drone ESCs. The PIC24E family also targets automotive body electronics, LED lighting drivers, and power conversion digital control when paired with external MOSFET/IGBT drivers.
Design considerations: this MCU operates from 3.0V to 3.6V; a regulated 3.3V rail is mandatory, not 5V-tolerant on most I/O. The -E suffix denotes extended temperature grade (-40C to +125C). Place 0.1uF decoupling capacitors near every VDD/VSS pair, and keep the analog AVSS/AVDD pair isolated with separate ferrite beads for clean ADC readings.

Catatan Desain
The PIC24EP256MC204-E/PT requires a regulated 3.0 V to 3.6 V supply; 3.3 V nominal is standard. Use an LDO such as MCP1700 or a switching regulator with low ripple (<50 mV). Place 0.1 uF decoupling capacitors within 5 mm of every VDD/VSS pin pair, with one bulk 10 uF tantalum or ceramic capacitor on the main 3.3 V rail. The analog AVDD/AVSS pair should be isolated from digital VDD/VSS with a ferrite bead or small L-C filter for clean ADC readings. Total current draw including I/O can reach 60 mA at full CPU activity.
Route analog signals (AN0-AN4, op-amp inputs) away from PWM switching traces and the high-current motor phases. Use a ground pour on the top layer beneath the MCU and stitch with vias around the perimeter to suppress noise coupling into ADC readings. Place the crystal oscillator or external clock source within 10 mm of the OSCI/OSCO pins, with a guard ring tied to analog ground. The 44-pin TQFP requires standard 0.8 mm pitch routing - keep out under the package for thermal vias to a bottom-side copper pad.
Do not apply 5 V to any I/O pin - the PIC24EP256MC204-E/PT is NOT 5 V tolerant. Use level shifters (e.g. TXB0108) when interfacing to 5 V logic. Configure unused I/O as outputs driven low, not floating, to minimize current draw. Ensure the MCLR pin has the proper 10 kohm pull-up and decoupling capacitor per Microchip guidelines; missing MCLR hardware causes programming failure. When using the internal op-amps, configure the negative input pin function even if unused, to prevent floating-input shoot-through current.
Estimated: At 70 MIPS continuous operation with all peripherals enabled, internal power dissipation is approximately 80-120 mW (CPU + ADC + PWM + ECAN). Junction-to-ambient thermal resistance for the 44-pin TQFP (10x10 mm) is approximately 40 C/W with standard JEDEC test PCB. At 25 C ambient, junction temperature rise is ~5 C - well within the -40 C to +125 C operating envelope. For high-ambient (>85 C) enclosures, increase copper pour area on top and bottom layers to reduce theta_JA.
Informasi Konformitas
RoHS compliant per Microchip product page. Extended -40 C to +125 C temperature grade is NOT equivalent to AEC-Q100 automotive qualification; this part is suitable for industrial and non-safety automotive body electronics but not for safety-critical automotive ECUs.
