MC56F82748VLH 概要
A Digital Signal Controller (DSC) is a hybrid device that combines the deterministic control of a microcontroller with the mathematical throughput of a DSP. In the broader taxonomy it sits between microcontrollers (MCU) and digital signal processors (DSP), inheriting the interrupt latency of an MCU and the single-cycle MAC engine of a DSP. The 56800EX core executes both standard C code and DSP instructions, enabling fixed-point control loops with cycle counts far below what a Cortex-M MCU can achieve. This hybrid positioning makes DSCs a popular choice for sub-100 kW motor drives and digital power supplies where field-oriented control (FOC) and PFC algorithms must run in software.
Key differentiating specifications include dual 12-bit ADCs with 16 channels and up to 3 MSPS sample rate, two 12-bit DACs, four FlexTimer/PWM modules with up to 12 PWM outputs, two on-chip op-amps and comparators, an integrated 12-bit cyclic ADC for high-precision sensing, and a Cyclic Redundancy Check (CRC) engine. The 64 KB Flash supports in-application programming and the 8 KB dual-port RAM allows zero-wait-state DSP operand access. Peripherals include QSPI, I2C, two SCI/UART, and a CAN-FD interface.
The 56800EX architecture uses a Harvard memory layout with separate program and data buses. The 100 MHz core produces a 10 ns instruction cycle and integrates a hardware multiply-accumulate (MAC) unit and a barrel shifter. This enables closed-loop current and voltage control loops to execute in under 1 microsecond, which is critical for switching frequencies of 20-100 kHz commonly used in high-efficiency motor drives and digital PFC stages.
Typical applications include HVAC compressor control, refrigerator inverter compressors, industrial servo drives, solar micro-inverters, telecom rectifier modules, and brushless DC (BLDC) fans and pumps. The integrated op-amps allow direct current sensing without external amplifiers, reducing BOM cost and PCB area.
Design consideration: pair the MC56F82748VLH with NXP's MC34PF3001A7EP power-management IC for clean rail sequencing and with isolated gate drivers (e.g., 6.5 A SiC/IGBT drivers) to switch the power stage. Ensure the analog supply (VDDA) is decoupled with a 100 nF ceramic placed within 5 mm of the pin.

主な用途
MC56F82748VLH の用途: 7 件s: BLDC / PMSM Motor Control, Digital Power Factor Correction (PFC), Solar Micro-Inverter, HVAC Compressor Inverter, Industrial Servo Drive, Telecom Rectifier Module, Appliance Inverter (Washing Machine / Refrigerator).
BLDC / PMSM Motor Control
The MC56F82748VLH drives field-oriented control (FOC) of brushless DC and permanent-magnet synchronous motors in appliances, drones, and industrial servo drives. Its 100 MHz 56800EX core executes a complete FOC loop (Clarke/Park transforms, SVPWM modulation, PI controllers) in under 5 us, comfortably fitting 20 kHz PWM cycles. The 16-channel 12-bit ADC samples phase currents simultaneously via dual ADCs, while the four FlexTimer modules generate complementary PWM with hardware dead-time insertion. The on-chip op-amps condition current-shunt signals directly, eliminating external amplifiers.
おすすめ
Digital Power Factor Correction (PFC)
In digital PFC boost stages for telecom rectifiers, server PSUs, and EV chargers, the MC56F82748VLH performs average-current-mode control with line-voltage feed-forward. Its 100 MHz core runs the control loop, RMS calculations, and AC-line frequency tracking within a 40 us cycle, supporting PFC frequencies up to 100 kHz. The 12-bit ADC with 3 MSPS captures instantaneous inductor current with 333 ns conversion time, enabling valley-sensing and critical-conduction-mode algorithms. Dual DACs generate reference voltages for analog housekeeping comparators.
おすすめ
Solar Micro-Inverter
The MC56F82748VLH is used in 250-500 W solar micro-inverters that convert a single panel's DC output to grid-tied AC. It runs MPPT (maximum power point tracking), grid-synchronization PLL, and anti-islanding detection in addition to the inverter control loop. The integrated CAN-FD interface enables module-level communication for monitoring and remote firmware updates. Its low quiescent current (<50 mA active) keeps night-time consumption within EU efficiency regulations, and the wide -40C to +105C operating range suits outdoor enclosures.
おすすめ
HVAC Compressor Inverter
Variable-speed HVAC compressors require sinusoidal torque control with smooth start/stop and power-factor-correction front-end. The MC56F82748VLH runs the PFC plus compressor FOC in a single chip, with the dual-port 8 KB RAM supporting real-time lookup tables for sinusoidal commutation and the 64 KB Flash storing field-weakening and vibration-suppression algorithms. Hardware comparators enable overcurrent protection in <200 ns, critical for IPM short-circuit detection in air-conditioning systems.
おすすめ
Industrial Servo Drive
Industrial servo drives for robotics and CNC machinery demand sub-millisecond position-loop bandwidth with deterministic latency. The MC56F82748VLH's 56800EX core and dual-port RAM enable synchronized position/current loops running at 8 kHz with consistent cycle times. The on-chip QSPI interface supports high-speed encoder feedback (e.g., BiSS-C or SSI absolute encoders), while CAN-FD connects to the machine's EtherCAT/CANopen network. The integrated op-amps reduce BOM cost by eliminating external current-sense amplifiers.
おすすめ
Telecom Rectifier Module
In -48 V telecom rectifier modules that deliver 24 V or 54 V DC to base-station equipment, the MC56F82748VLH implements totem-pole PFC plus LLC resonant converter control. Its 12-bit ADC synchronizes with the LLC switching frequency for primary-side regulation, and the FlexTimer PWM modules generate the complementary gate-drive waveforms with programmable dead time. The -40C to +105C operating range meets outdoor telecom-shelf environmental requirements, and CAN-FD enables module-to-shelf communication for load-sharing.
おすすめ
Appliance Inverter (Washing Machine / Refrigerator)
In residential appliances such as direct-drive washing machines and refrigerator inverter compressors, the MC56F82748VLH provides a cost-optimized single-chip FOC solution. The integrated op-amps and comparators reduce external component count, while the 64 KB Flash stores both the motor-control firmware and the appliance-specific user-interface logic. The CAN-FD interface connects to the appliance's main control bus, enabling remote diagnostics via the manufacturer's cloud platform. Low active power consumption improves ENERGY STAR compliance ratings.

設計ノート
Estimated: at 100 MHz CPU activity driving all peripherals, the MC56F82748VLH draws approximately 60-80 mA from VDD (1.2 V internal core) plus 10-20 mA from VDDA. Use a low-noise LDO such as NXP's MC34PF3001A7EP for the 3.3 V rail, followed by a ferrite bead and 100 nF + 10 uF decoupling network on each VDD/VDDA pin pair. Place the 100 nF caps within 5 mm of the IC pins. Add a 10 uF bulk tantalum or ceramic on the board's main 3.3 V rail. Failure to decouple analog and digital supplies separately can couple switching noise into the ADC, degrading current-sense accuracy in motor-control loops.
Route analog signals (AN0-AN15, OPAP/OPAM, CMP inputs) on a separate inner layer or directly on the top layer shielded by a ground pour. Keep analog traces short (<25 mm) and at least 3 mm away from PWM switching signals to avoid capacitive coupling. The exposed thermal pad is not present on the LQFP-64 package, but a continuous ground pour on the top and bottom layers directly under the IC reduces die temperature by 5-10 C at full load. Use 4-layer PCB with dedicated ground and power planes for noise-sensitive motor-control designs.
Do not exceed the absolute maximum VDD of 4.0 V; transients above this rating cause permanent damage. Always assert RESET_b for at least 100 ms after VDD reaches 3.0 V to allow the internal voltage regulator to stabilize. The XTAL/EXTAL pins require a 4-16 MHz fundamental-mode crystal with loading capacitors matched to the crystal's specified load capacitance (typically 8-12 pF). Do not use the VPP pin (pin 64) for any external connection - it is reserved for factory Flash programming only and may inject noise if left floating or driven externally.
コンプライアンス情報
RoHS and REACH compliant per NXP product page. Not AEC-Q100 qualified - the MC56F82748 family targets industrial and consumer motor-control applications, not automotive. Operating temperature -40C to +105C supports industrial-grade deployments.
