DSP56F801FA60E - 16-bit DSC, 60MHz, 16KB Flash, LQFP-48 | NXP
MPN： DSP56F801FA60E ✗ 停產DSP56F801FA60E 概覽
A Digital Signal Controller is a hybrid processor class that merges the Harvard-style multiply-accumulate architecture of a DSP with the peripheral set, interrupt structure, and control peripherals of a microcontroller. Within the power-management semiconductor hierarchy, the DSC sits above generic MCUs for control-loop-intensive tasks such as field-oriented motor control and switched-mode power conversion, where deterministic MAC throughput and fast interrupt response are mandatory.
Key features include the 56800 CISC/Harvard-style core executing 60 million instructions per second, on-chip Flash for field reprogrammability, a flexible peripheral set including PWM, ADC, timers, and serial interfaces (per NXP product documentation), and 3.3V single-supply operation. The industrial-grade E-suffix temperature range supports demanding environments, and the 48-LQFP footprint delivers a cost-effective, compact solution for embedded motion control.
Technically, the 56800 core uses dual Harvard buses allowing simultaneous instruction and data fetches, hardware MAC units, and bit-manipulation instructions typical of MCUs. Per Freescale/NXP datasheet documentation, thermal resistance Theta-JA was simulated to JEDEC JESD51-2 in natural convection for the LQFP package.
Typical applications include servo and industrial motor control, power inverters, DC-DC converters, and digital power supplies, where the combination of fast MAC throughput and PWM peripherals in one chip reduces system cost and board area.
Design consideration: the part is End of Life per NXP product page, so new designs should evaluate the MC56F8xxxx successor family or cross-brand DSCs, and existing designs should secure last-time-buy inventory.

典型應用
DSP56F801FA60E 適用於 6 應用s: Servo Motor Control, Power Inverters, DC-DC Converters and Digital Power, Industrial Automation and Embedded Control, Consumer Appliance Motor Drives, Automotive-Adjacent Motion Subsystems.
Servo Motor Control
The DSP56F801FA60E fits servo drive control because its 56800 core executes 60 MIPS with single-cycle MAC instructions, enabling field-oriented control (FOC) current loops at PWM frequencies of 16-20 kHz within deterministic interrupt latency. Its on-chip PWM module and fast ADC (per NXP 56F801 datasheet) close the current loop entirely on-chip, while 16KB Flash stores position-loop and commutation firmware. Placed as the single main controller between the encoder interface and the gate-driver stage, it eliminates a separate MCU-plus-DSP pairing, cutting BOM cost and board area in compact servo axes.
推薦
Power Inverters
For DC-AC power inverters, the DSP56F801FA60E provides synchronized multi-channel PWM generation at 60 MHz core speed, allowing center-aligned sine-wave modulation with dead-time insertion and closed-loop voltage regulation. The 16-bit fixed-point 56800 architecture handles coordinate transforms and PI compensation with the throughput needed for 20 kHz switching. Its 3.3V supply integrates cleanly with isolated gate-driver chains, and the 48-LQFP 7x7 mm package suits compact inverter PCBs. Because the part is EOL, designers should pair it only with last-time-buy inventory or migrate to MC56F8xxxx successors.
推薦
DC-DC Converters and Digital Power
Digital power supplies benefit from the DSP56F801FA60E's deterministic control loop: the 56800 core runs peak-current-mode or average-current-mode compensation with sub-microsecond ISR response at 60 MHz. The on-chip ADC samples output voltage and current, while the PWM peripheral drives the power stage synchronously with sampling to minimize control delay. 16KB Flash is sufficient for full compensation, soft-start, and protection firmware. Its industrial temperature grade suits telecom and industrial rectifier environments. The 48-LQFP footprint supports dense power boards with tight analog-digital partitioning.
推薦
Industrial Automation and Embedded Control
In factory automation nodes, the DSP56F801FA60E doubles as a signal-processing and general control unit: Harvard dual-bus architecture delivers DSP-class filtering (FIR/IIR) on sensor streams while MCU-style bit manipulation, timers, and serial peripherals handle I/O sequencing and communication. The industrial temperature E-grade and 3.3V single supply simplify integration into 24V-system panels with proper level translation. Its low cost per unit made it popular in high-volume machine sub-controllers; EOL status means existing deployments should qualify MC56F8xxxx or C2000 parts for future spares.
推薦
Consumer Appliance Motor Drives
Appliance applications such as fan, pump, and compressor drives used the DSP56F801FA60E for sensorless BLDC control: the 60 MHz core executes sliding-mode or back-EMF observers in fixed point while the PWM module drives a three-phase inverter with hardware dead-time. The 16KB Flash accommodates sensorless commutation plus protection code, and the cost-optimized 48-LQFP package fits low-profile appliance control boards. Its 3.3V logic interfaces directly with standard gate drivers. For new appliance platforms, NXP's MC56F8xxxx and TI C2000 families provide active-lifecycle successors.
推薦
Automotive-Adjacent Motion Subsystems
The industrial-grade DSP56F801FA60E has been used in non-safety automotive-adjacent subsystems such as pumps, actuators, and HVAC blowers, where its 60 MIPS fixed-point throughput supports FOC with onboard current sensing. Designers value the single-chip integration of ADC, PWM, and timers, which shortens the control loop and reduces component count in space-constrained modules. Note that this part is not AEC-Q100 qualified and is EOL; new automotive programs should instead use Q1-qualified C2000 devices such as the TMS320F28035PNT or TMS320F280041-Q1 with equivalent peripherals.

設計說明
The DSP56F801FA60E is End of Life per NXP product page with a discontinuance PCN published. Before committing to it in any build, secure sufficient last-time-buy stock for the product lifetime, or qualify MC56F8322 (active, same 56800 architecture) with a PCB respin. Verify RoHS/environmental declarations on the NXP Environmental Quality tab for your date codes, as EOL parts sourced from brokers may include non-compliant legacy stock.
The device operates from a single 3.3V supply. Decouple VDD with 0.1uF ceramic capacitors at each supply pin plus one 10uF bulk capacitor, placed within 2 mm of the pins. In motor-drive environments, gate-driver switching transients couple through the ground plane - use a solid ground pour under the LQFP and separate analog supply filtering for the ADC reference path to preserve conversion accuracy in current-loop control.
Per the NXP DSP56F801 datasheet, Theta-JA was simulated to JEDEC JESD51-2 in natural convection for the 48-LQFP. At 60 MHz the device dissipates modest power, but ensure at least 4x2 via fan-out from the thermal pad area to ground planes and avoid enclosing the chip under tall adjacent components in sealed industrial enclosures to keep junction temperature within industrial range limits.
