MC56F8256VLF - 60MHz 16-Bit DSC, 64KB Flash | NXP
MPN： MC56F8256VLF ✗ 停產MC56F8256VLF 概覽
A digital signal controller is an MCU-oriented processor architecture that adds efficient numerical and control-loop processing to a microcontroller platform. In the broader hierarchy, a DSC is a specialized microcontroller and processor that sits between a general-purpose MCU and a dedicated digital signal processor. The 56800E core is intended for embedded control tasks where deterministic execution, peripheral integration, and compact real-time processing are more valuable than a desktop-class operating system.
The 60 MHz core provides the principal processing headline for the MC56F8256VLF, while 64 KB of flash supports embedded firmware storage. The device is packaged in a 48-LQFP, a leaded quad flat package identified in the verified data as QFP 48 and 7x7 mm. NXP describes the MC56F825x/MC56F824x family as combining DSP processing power and microcontroller functionality with flexible peripherals. Exact peripheral assignments, timer details, converter specifications, memory maps, and electrical limits are not included in the supplied verification and should be checked against the manufacturer datasheet before design release.
Typical application areas are power conversion, motor control, and other consumer or industrial embedded systems where a compact control processor is needed. For these uses, the 60 MHz 56800E core can execute control and signal-processing tasks without requiring a separate processor, while the 3 V to 3.6 V supply range aligns the device with conventional embedded power systems. The package also provides a defined 48-pin footprint for board-level integration.
A key design consideration is the distinction between a processor that is suitable for a control system and a confirmed drop-in replacement. The supplied data does not provide verified pin-level compatibility for any substitute, and the NXP product page identifies the part as end-of-life. Production sourcing should therefore account for lifecycle risk, verify supply availability, and validate firmware, peripheral mapping, timing, and PCB compatibility before substituting any alternative.
This product data page consolidates verified manufacturer and distributor information, current lifecycle indication, package identity, technical search terms, and sourcing context. It is intended to support early component selection and procurement review while clearly separating verified facts from parameters that require datasheet confirmation.

典型應用
MC56F8256VLF 適用於 6 應用s: Power Conversion Control, Motor Control Systems, Industrial Embedded Control, Consumer Signal Processing, Digital Signal Processing Control, Compact 3.3V Control Boards.
Power Conversion Control
The MC56F8256VLF fits compact power-conversion control because NXP identifies the MC56F825x/MC56F824x family as an application fit for power conversion. Its 60 MHz 56800E core can execute fast control calculations while retaining microcontroller-style integration, and the verified 3 V to 3.6 V supply range is compatible with embedded power-control systems. The 48-LQFP package provides a defined 48-pin implementation platform. Before selecting it for a converter, verify the required PWM channels, timers, ADC interfaces, fault handling, and analog signal paths in the manufacturer datasheet; those specifications are not included in the supplied search excerpts.
推薦
Motor Control Systems
The MC56F8256VLF is suitable as the control processor in a motor-control system because its verified 60 MHz 56800E core combines digital signal processing with microcontroller functionality. That architecture is appropriate for current loops, speed calculations, and real-time sequencing when the required timers, PWM resources, and feedback interfaces are available. The 48-LQFP package supports a conventional surface-mount controller implementation, while the 3 V to 3.6 V operating range supports embedded systems. Exact PWM resolution, encoder support, analog channels, and fault-response behavior must be confirmed from the official datasheet before replacing a purpose-built motor controller.
推薦
Industrial Embedded Control
The MC56F8256VLF can be evaluated for industrial embedded control applications that require a dedicated real-time processor rather than a general-purpose host controller. Its 16-bit 56800E DSC core, 60 MHz clock, and 64 KB flash provide a defined processing and firmware baseline, while the 3 V to 3.6 V supply supports embedded board-level implementations. The package is a 48-LQFP, 7x7 mm surface-mount device suitable for compact control assemblies. Industrial suitability is not established by the supplied data beyond the NXP positioning for consumer and industrial applications; environmental, isolation, EMC, and functional-safety requirements need separate system-level verification.
推薦
Consumer Signal Processing
The MC56F8256VLF may be used in consumer embedded products where local signal processing and control are needed without a separate high-power processor. The 56800E core's 16-bit DSC positioning, 60 MHz operating frequency, and microcontroller integration are useful for responsive control loops and peripheral coordination. Its 64 KB flash provides the verified firmware baseline for compact applications, while the 48-LQFP package supports board-level assembly. The supplied data does not identify specific consumer peripherals, audio interfaces, memory, or certification requirements, so those claims should not be treated as product guarantees. Verify application-specific interfaces and lifecycle risk in the NXP documentation.
推薦
Digital Signal Processing Control
The MC56F8256VLF is directly aligned with digital signal processing control because it is a 56800E-based 16-bit DSC rather than only a general-purpose MCU. The 60 MHz operating frequency provides the headline execution rate for embedded numerical workloads, while the integrated microcontroller characteristics support peripheral control and system firmware. This positioning is useful for compact signal-processing controllers that must coordinate sampling, timing, and control functions. However, the supplied data does not specify the DSP instruction set details, converters, memory bandwidth, or interrupt latency, so designers should use the manufacturer datasheet to quantify throughput before selecting the device for a particular algorithm.
推薦
Compact 3.3V Control Boards
The MC56F8256VLF is a candidate for compact 3.3 V control boards because its verified operating supply range is 3 V to 3.6 V and its package is a 48-LQFP measuring 7x7 mm. The 60 MHz processor provides a meaningful control-clock baseline without requiring a separate DSP, and the 64 KB flash capacity is a defined starting point for firmware. Designers should plan power decoupling, signal integrity, and thermal review around the final supply, clock, and peripheral configuration. The provided data does not include absolute maximum ratings, recommended capacitor values, or pin-level guidance, so those implementation details must come from the official NXP datasheet.

主要差異化特點
- Verified 60 MHz 56800E DSC positioning (對比MC56F8246VLF)
- Confirmed 3 V to 3.6 V supply range (對比MC56F8346VFVE)
- Known 48-LQFP 7x7 mm package identity (對比MC56F8323VFBE)
設計說明
Design the supply rail around the verified 3 V to 3.6 V operating range and confirm the device's absolute maximum and recommended voltage limits from the official NXP datasheet. Place local bulk and high-frequency decoupling capacitors close to the appropriate power and ground pins, and verify the capacitor voltage rating with margin for transients. Because the MC56F8256VLF is an end-of-life part, validate supply sequencing and startup behavior on the exact board revision rather than relying only on generic controller assumptions.
Use the verified 48-LQFP 7x7 mm package as the starting point for land-pattern selection, but obtain the official package drawing before routing. Confirm pin numbering, exposed thermal or thermal-pad details, pad dimensions, solder mask, paste, and assembly tolerances against the manufacturer documentation. A same-package ordering code is not automatically pin-compatible; verify every power, ground, clock, reset, debug, and peripheral signal in the pin table.
Do not treat MC56F8246VLF, MC56F8346VFVE, MC56F8323VFBE, MC56F8006VLF, or MC56F8013VFAE as approved replacements merely because they appear in related searches. The supplied sources do not establish identical memory, peripherals, pin assignments, or lifecycle terms. For an end-of-life device, create a migration matrix covering clock, flash, RAM, ADC, PWM, timers, communication interfaces, supply voltage, package, software, and qualification, then validate the final choice with hardware-in-the-loop testing.
合規資訊
The supplied verified excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than inferred.
