Typical applications include three-phase brushless DC (BLDC) and permanent-magnet synchronous motor (PMSM) drives, industrial power conversion (inverters, converters, UPS), and digital power supplies where fast deterministic control loops at 60 MHz are essential. When designing with this device, verify availability early: NXP lists this part as NRND (Not Recommended for New Designs), so new projects should evaluate the recommended successor family, and existing designs should secure last-time-buy inventory.

MC56F8347VPY60 - 60MHz 16-bit DSC, 128KB Flash | NXP | 160-LFQFP
The NXP (formerly Freescale) MC56F8347VPY60 is a 16-bit Digital Signal Controller (DSC) combining the peripheral set and ease-of-use of an MCU with the computational power and throughput of a DSP, operating at 60 MHz with 128 KB of on-chip program Flash and 160 pins in an LQFP-160 (LFQFP) industrial-grade package. The MC56F8347VPY60 is built on the 56800E core family and integrates peripherals tuned for digital motor control, power conversion, and embedded signal processing applications, delivering up to 60 MIPS of deterministic throughput for closed-loop control loops. A Digital Signal Controller is a hybrid class of embedded processor that fuses a microcontroller's deterministic interrupt-driven peripheral set with a digital signal processor's single-cycle MAC (multiply-accumulate) engine and parallel data paths. DSCs sit in the hierarchy between general-purpose microcontrollers (which lack DSP throughput) and standalone DSPs (which lack on-chip analog/control peripherals), making them the de-facto choice for digital motor control, switched-mode power supplies, sensor signal conditioning, and high-speed instrumentation. The 56F83xx family specifically targets embedded real-time control where deterministic latency, on-chip ADCs/PWMs, and DSP-grade math are required in a single chip. Key features include a 60 MHz 56800E Harvard-architecture core with single-cycle 16-bit x 16-bit MAC, 128 KB of program Flash, 8 KB of unified data/program RAM, dual 12-bit ADCs with 1.5 us conversion time, a 6-channel PWM module with programmable dead-time insertion, a Quadrature Decoder, multiple serial interfaces (SCI, SPI, I2C), a 4-channel DMA controller, and an external memory interface to LQFP-160 packages with up to 76 general-purpose I/O pins. The 'VPY' package suffix indicates the 160-pin LFQFP industrial-temperature grade (-40C to +105C), and the '60' suffix denotes 60 MHz operation. The 56800E core implements a modified Harvard architecture with three execution units operating in parallel: an Address Generation Unit (AGU), a Data Arithmetic Logic Unit (DALU), and a Program Controller. The single-cycle MAC engine delivers up to 60 MIPS of signal-processing throughput, while the on-chip dual 12-bit ADC samples at up to 1.5 us per conversion enabling precise current/voltage sensing in motor control loops. The on-chip regulator and brown-out detector enhance robustness for industrial environments. Typical applications include AC induction motor vector control, permanent-magnet synchronous motor (PMSM) field-oriented control (FOC), digital PFC power factor correction, uninterruptible power supplies (UPS), solar micro-inverters, three-phase UPS systems, industrial servo drives, and sensor signal processing instrumentation. The dual ADC with simultaneous sampling enables field-oriented control current loops at switching frequencies up to 50 kHz without external ADC support. When designing with this device, carefully plan PCB thermal dissipation: at 60 MHz the core dissipates approximately 0.5 W, and the LFQFP-160 package requires at least 25 cm^2 of 2 oz copper pour for adequate cooling. Designers should also validate toolchain compatibility with CodeWarrior IDE or the Processor Expert tool suite, as the 56800E core requires the legacy 56F8xxx SDK for peripheral drivers and the CW56800 compiler for the C/C++ source.

MC56F8355MFGE - 16-bit 60MHz DSC 256KB Flash | NXP
The NXP MC56F8355MFGE is a 16-bit digital signal controller (DSC) based on the 56800E core, running at 60 MHz with 256 KB (128K x 16) of on-chip flash program memory, housed in a 128-pin LQFP (14x20 mm) package. A digital signal controller combines the computational architecture of a digital signal processor (DSP) with the peripheral set and control structure of a microcontroller. In the product hierarchy, the MC56F8355MFGE sits within NXP's 56800E core-based DSC family, under digital signal controllers, under hybrid microcontrollers, and under the broader semiconductor/IC category. This hybrid architecture allows a single chip to execute both tight real-time signal-processing loops and general control firmware. Key features include a 16-bit 56800E core at 60 MHz, 256 KB flash, dual 12-bit ADC converters for simultaneous sampling, and integration of CAN, SCI, and SPI serial interfaces with 49 general-purpose I/O lines. The dual ADCs are significant for motor control because phase currents on multiple legs can be sampled at precisely the same instant. Technically, the 56800E core blends Harvard-architecture DSP execution (single-cycle MAC, hardware looping, bit-reversed addressing) with a conventional MCU programming model, supported by the NXP CodeWarrior development environment and the Processor Expert configuration tool. The 56F835X/815X family members share a common peripheral set and documentation, easing migration between memory densities. Typical applications are high-precision motor control (BLDC, PMSM, AC induction with FOC), digital power conversion such as switched-mode power supplies and inverters, and industrial automation nodes requiring deterministic real-time control. Per NXP, the device enables high-precision motor control with 60 MHz performance and dual 12-bit ADCs. Design consideration: the device operates from 2.25 V to 3.6 V over -40 C to +125 C, so 5 V sensor signals need level shifting, and flash retention and Vcap pin requirements documented in the datasheet must be honored.

MC56F8356MFV60 - 60MHz 16-bit DSC, 144-pin LQFP | NXP
The NXP MC56F8356MFV60 is a 60 MHz 16-bit hybrid Digital Signal Controller (DSC) from the 56F8300 family, integrating the 56800E core with DSP and MCU functionality on a single die, delivered in a 144-pin LQFP package with 1 DSP engine and 256 KB of program Flash. According to the Freescale/NXP 56F8356/56F8156 Technical Data document, the device includes 4 KB unified RAM, 8 KB data Flash, dual 12-bit ADCs, FlexPWMs, FlexCAN, and an external memory interface, enabling migration paths from the 56F8346 with minimal hardware changes. A Digital Signal Controller (DSC) is a hybrid semiconductor that combines a microcontroller's deterministic control peripherals with a digital signal processor's MAC engine and parallel math pipelines, occupying the hierarchical position: DSC -> hybrid controller -> microcontroller -> embedded processor -> semiconductor. Compared with a pure MCU, a DSC executes motor-control and power-conversion control loops at much higher throughput; compared with a standalone DSP, a DSC integrates on-chip analog, timers, and communication peripherals, eliminating the need for an external ASIC. Key features of the MC56F8356MFV60 include up to 60 MHz core frequency (56800E core, 60 MIPS class), up to 512 KB total memory address space, 4 KB of unified RAM plus 8 KB data Flash, dual 6-output FlexPWM modules with fault inputs, two 12-bit ADCs with up to 8 input channels and 1.7 microsecond conversion, one FlexCAN module, two SCI/UART ports, one SPI port, and JTAG/Enhanced OnCE debug interface. The 144-pin LFQFP package supports an external memory bus for SRAM/Flash expansion and operates from 3.0V to 3.6V single supply. Architecturally, the 56800E core uses a dual Harvard architecture with separate program and data memories, hardware DO/REP loops, and a 16-bit x 16-bit MAC plus 32-bit barrel shifter, executing most DSP instructions in one clock cycle. The integration of pulse-width modulation, 12-bit analog capture, and CAN on the same bus reduces BOM cost and PCB area for motor drives, while the external memory interface lets designers attach external SRAM or Flash beyond the internal 256 KB. Typical applications include AC induction motor vector control, brushless DC motor drives, uninterruptible power supplies, welding inverters, automotive body controllers, and industrial PLCs. The wide temperature range of -40C to +125C and the JTAG debug support suit it for harsh-environment factory automation. When designing, ensure decoupling capacitors are placed within 5 mm of each supply pin and use 4-layer PCB stackup to keep ADC reference noise below 1 LSB. For audio or RF signal chains this device is not a fit - it lacks high-resolution audio converters and is optimized for control-loop DSP rather than high-frequency signal processing.

MC56F8356MFVE - 16-bit 60MHz DSC, 256KB Flash | NXP
The NXP Semiconductors MC56F8356MFVE is a 16-bit digital signal controller (DSC) based on the 56800E core, operating at up to 60 MHz with 256KB (128K x 16) of on-chip flash memory, housed in a 144-pin LQFP (20x20 mm) surface-mount package. A digital signal controller is a hybrid device that combines the computational throughput of a digital signal processor (DSP) with the peripheral integration and control flow of a microcontroller (MCU). Within the power management hierarchy, the 56800E-based 56F8xxx family sits between general-purpose MCUs and dedicated DSPs, offering single-cycle MAC instructions, hardware loops, and bit manipulation suited to real-time closed-loop control such as motor control and power conversion. Key features of the MC56F8356MFVE include the 16-bit 56800E CISC core at 60 MHz, 256KB program flash, on-chip RAM, 2.5V/3.3V supply operation, and a rich peripheral set typical of the 56F835x family including PWM modules, ADCs, timers, and serial communication interfaces for embedded control systems. Architecturally, the 56800E core executes a dual Harvard-style instruction fetch with dedicated address generation units, allowing simultaneous multiply-accumulate and address arithmetic. This enables deterministic execution of control loops such as field-oriented motor control, digital power supplies, and sensor signal processing without external memory. Typical applications include industrial motor drives, switching power supplies and inverters, digital UPS systems, and automotive auxiliary control units where the combination of DSP math and MCU peripherals reduces bill-of-materials complexity. A key design consideration: NXP lists the MC56F8356MFVE as End of Life (EOL). New designs should evaluate pin-compatible family members or newer 56F8xxxx series parts, while existing designs should secure last-time-buy inventory.

MC56F8357VVFE - 16-bit DSC 60MHz 256KB Flash | NXP
The NXP (Freescale Semiconductor) MC56F8357VVFE is a 16-bit digital signal controller (DSC) based on the 56800E hybrid core, running at up to 60 MHz with 256KB (128K x 16) of on-chip Flash program memory, housed in a 160-pin MAPBGA package measuring 15 x 15 mm. A digital signal controller combines the computational architecture of a digital signal processor (DSP) with the peripheral set and control-oriented instruction flow of a microcontroller (MCU). In the product hierarchy, the MC56F8357VVFE sits within NXP's 56800E family of hybrid controllers: DSC -> digital signal processor -> embedded processor -> semiconductor. This hybrid architecture allows a single chip to execute both tight math loops (FFT, filter kernels, PI control) and general-purpose control code, eliminating a separate MCU-plus-DSP two-chip design. Key features of the MC56F8357 include the 16-bit 56800E core executing the DSP/MCU mixed instruction set at 60 MHz, 256KB of Flash program memory, and a large peripheral suite typical of the 56F8300 family, including pulse-width modulation (PWM) blocks targeted at motor control, analog-to-digital converters, general-purpose I/O (76 I/O per the digchip datasheet summary), and serial communication interfaces. The external oscillator type allows precise clocking from a system crystal. Architecturally, the 56800E core uses a Harvard-style dual-bus structure with hardware MAC (multiply-accumulate) support, enabling single-cycle DSP instructions while retaining efficient C-compiler friendliness. Flash memory is programmed and erased on-board, supporting field firmware updates in deployed industrial equipment. Typical applications for the MC56F8357VVFE include industrial motor control (BLDC, PMSM, AC induction drives), digital power conversion (switch-mode power supplies, UPS, inverters), and embedded control systems requiring deterministic DSP-class processing. The rich PWM peripherals and 60 MHz core make it a strong fit for field-oriented control algorithms. Design consideration: as a 0.5 mm-pitch 160-ball BGA, this device demands a controlled-impedance multilayer PCB, and the part has been superseded in NXP's roadmap by newer MC56F8xxxx devices - verify lifecycle status before new designs.

MC68882CRC20A - 32-bit Floating-Point Coprocessor, 20 MHz | NXP
The NXP MC68882CRC20A is a 32-bit floating-point coprocessor (FPU) designed to pair with the Motorola 68020 and 68030 microprocessor families, operating at 20 MHz, and housed in a 68-pin Pin Grid Array (CPGA-68 / PGA-68, 26.92 × 26.92 mm) through-hole package. The original manufacturer was Motorola; NXP continues to offer the part under the legacy M68K product line. A floating-point coprocessor (FPU) is a specialized processor that offloads IEEE 754 floating-point arithmetic from the main CPU, executing add, subtract, multiply, divide, square root, and transcendental operations in hardware. The 68882 sits between the 68k CPU and main memory on the M68000 coprocessor interface, transparently handling floating-point opcodes issued by the host. In the broader taxonomy, the 68882 is a math coprocessor, then a numeric data processor, then a specialized processor, and finally a member of the integrated-circuit family of computing devices. Key features include full IEEE 754 single- and double-precision arithmetic, 46 MIPS performance capability, eight 80-bit floating-point registers, and a memory-mapped coprocessor interface conforming to the M68000 family coprocessor protocol. The device integrates transcendental functions (sine, cosine, log, exp) in hardware and supports exception handling consistent with the 68020/68030 architecture. The MC68882CRC20A uses a fully static CMOS design with separate instruction and data paths, executing up to one floating-point operation per clock cycle for simple instructions. Built-in pipeline registers and pipelined multipliers allow the part to overlap operand fetches with arithmetic, which is what enables the 46 MIPS peak throughput. The device is software-compatible with the earlier MC68881 FPU. Typical applications include workstation-class computing, embedded M68K systems, aerospace and defense retrofits, industrial CNC controllers, and legacy military/aerospace platforms that still rely on the 68020/68030 CPU. The wide temperature tolerance and through-hole PGA package make the CRC20A well suited for chassis-mounted industrial cards and ruggedized systems. When designing with this part, ensure the coprocessor interface is correctly terminated on the host CPU side; signal timing must follow the 68020/68030 coprocessor specification. The PGA package requires a socket for field-replaceability on long-lifecycle industrial systems.

MC68882CRC25A - 25 MHz FPU Coprocessor, 68-PGA | Motorola
The Motorola MC68882CRC25A is a 25 MHz HCMOS floating-point coprocessor (FPU) designed as a companion to the Motorola 68020 and 68030 M68K family processors, housed in a 68-pin ceramic pin grid array (PGA / BCPGA, 26.92 x 26.92 mm) package. It implements the IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std 754-1985) at single, double, and extended precision with eight 80-bit floating-point registers, delivering 46 MIPS of floating-point throughput. The coprocessor operates from a single 5 V supply and supports asynchronous bus interface timing that matches its host CPU. What is a floating-point coprocessor? A floating-point coprocessor is a specialized processor that offloads arithmetic-intensive operations (add, subtract, multiply, divide, square root, transcendental functions) from the main CPU. Coprocessors belong to the broader category of arithmetic logic units, processor extensions, and finally semiconductor ICs. The MC68882 specifically extended the M68K CISC architecture with hardware IEEE-754 compliance, which the 68020's built-in FPU lacked for full conformance. Key features of the MC68882CRC25A include full IEEE 754 conformance with rounding modes (round to nearest, toward zero, toward +inf, toward -inf), extended precision 80-bit registers, complete exception handling with 16 exception vector types, and software-selectable precision control. The 25 MHz speed grade corresponds to a 40 ns cycle time and suits 68020/68030 systems running at the same clock frequency. Architecturally, the MC68882 uses a 32-bit HCMOS internal data path, an 8-deep instruction prefetch queue, and dedicated hardware for denormalized number handling. The chip communicates with the host through coprocessor interface instructions (cpGen, cpDBcc, cpScc, cpBcc, cpRESTORE, cpSAVE) per the M68K definition, ensuring tight CPU-FPU coupling with zero glue logic required. Typical applications include legacy UNIX workstations, scientific and engineering workstations running floating-point-intensive CAD/CAE codes, military and aerospace vector graphics systems, and industrial motion-control DSP front-ends. The 68-PGA package was designed for socketed through-hole assembly on early 1990s motherboards and add-in accelerator cards. When designing with this part, ensure the host CPU is a 68020 or 68030 with coprocessor interface signals properly terminated. The MC68882CRC25A is discontinued (NRND/EOL); verify lifetime-buy requirements with Rochester Electronics, the last authorized distributor, before committing to new designs.

MC68882EI16A - 16MHz 68040 FPU Co-Processor | NXP PLCC-68
The NXP MC68882EI16A is a 16 MHz floating-point unit (FPU) co-processor from the Motorola/Freescale 680x0 family, packaged in a 68-pin Plastic Leaded Chip Carrier (PLCC, 24.21 x 24.21 mm) for surface-mount assembly. It executes IEEE 754 single, double, and extended-precision floating-point operations and pairs with MC68020/MC68030/MC68040 host CPUs as a co-processor over the M68000 coprocessor interface. The 'EI' suffix denotes the industrial operating temperature grade and '16A' denotes the 16 MHz clock rating. An FPU (Floating-Point Unit) is a specialized arithmetic logic unit that performs floating-point arithmetic - operations on non-integer real numbers represented in IEEE 754 format. In the M68000 family hierarchy, the 68882 sits as a co-processor companion to integer CPUs: CPU -> 680x0 integer core -> FPU co-processor (68881/68882) -> M68000 family -> CISC microprocessor -> integrated circuit. The 68882 is the second-generation FPU that adds extended-precision support and on-chip conversion instructions versus the original 68881. Key features include eight floating-point data registers (FP0-FP7), full IEEE 754 conformance including rounding modes and gradual underflow, and instruction-level concurrency with the host CPU. The device is widely used to upgrade legacy 68020/68030 designs where software-only floating-point emulation is too performance-cost-heavy. The PLCC-68 surface-mount package suits through-hole repair (SMD variants require hot-air rework rather than socketed DIP). The architecture uses a parallel multiply-add pipeline and a hardware microcode ROM. It communicates with the host CPU via dedicated coprocessor protocol lines (CP signals) and shares the address/data bus during operand transfers. Conformance to IEEE 754 means software compiled for the 68882 behaves identically to code targeting a software IEEE 754 library, enabling portable numeric code. Typical applications include legacy workstation acceleration, industrial CNC controllers, scientific instrumentation, avionics retrofitting (where the partner's Army/Navy systems still use 68030-class CPUs), and 68040-based embedded controllers in factory automation. The 16 MHz speed grade is the mainstream variant; higher-grade 20 MHz/25 MHz parts exist for performance-bound designs. When designing with the MC68882EI16A, ensure the host CPU is configured to drive the CP (coprocessor) interface correctly. The 68882 cannot operate as a stand-alone CPU; it requires a valid 68020, 68030, or 68040 host. Watch for thermal management - though the PLCC package is more forgiving than QFP, extended industrial temperature operation may require airflow. This page synthesizes NXP/Freescale distributor listings, drop-in alternative candidates within the 68881/68882 family, and practical guidance for legacy M68000 designs not typically consolidated into a single product page.
MC68882EI25A - 25 MHz HCMOS FPU Coprocessor | NXP / Motorola
The NXP / Motorola MC68882EI25A is a 25 MHz HCMOS Enhanced Floating-Point Coprocessor (FPU) for the MC68020/MC68030 32-bit microprocessor family, housed in a 68-pin PLCC (Plastic Leaded Chip Carrier) package with J-leads and a 24.21 mm x 24.21 mm body. It executes IEEE 754 standard single- and double-precision floating-point operations in hardware, offloading transcendental, trigonometric and decimal conversion routines from the host CPU. The 25 MHz speed grade pairs directly with the 25 MHz MC68020 or 25/33 MHz MC68030 MPU through the dedicated M68000 coprocessor interface. An FPU, or Floating-Point Unit, is a specialized hardware block that performs floating-point arithmetic with much higher throughput and precision than a general-purpose CPU using software emulation. The MC68882 sits in the same hierarchy as FPU -> math coprocessor -> numeric processor -> specialized processor, and historically was the high-performance IEEE-754 solution for the M68K platform before integrated MMUs/FPUs became common in mainstream CPUs. Designers used it for CAD workstations, scientific simulations and graphics engines where 32-bit and 64-bit floating-point performance was essential. Key features of the MC68882EI25A include full IEEE 754 single (32-bit) and double (64-bit) precision with extended-precision (80-bit) internal format, eight 80-bit floating-point registers usable as a stack or as a register file, full support for the M68000 coprocessor interface, hardware support for add, subtract, multiply, divide, square-root, and transcendental functions (sine, cosine, log, exp, etc.), and built-in exception handling for overflow, underflow, inexact and invalid-operation traps. The 25 MHz rating matches the 25 MHz MC68020FN25 host CPU clock. Architecturally, the MC68882 uses a hardwired microcoded control unit with a multi-cycle execution pipeline, an 80-bit internal mantissa path, and a dedicated bus interface to the host MPU. The HCMOS process allows higher clock speeds and lower power than the original NMOS MC68881. The 'EI' suffix in the part number typically denotes an industrial/commercial temperature grade plastic PLCC package. Typical applications include workstation-class CAD/CAM systems, simulation and modeling computers, professional graphics rendering engines, scientific instruments, industrial process controllers, avionics displays, and legacy M68K embedded systems using the MC68020 or MC68030. It is also used in legacy aerospace/industrial retrofits where legacy Motorola M68K software must be preserved on modern hardware redesigns. Design consideration: the MC68882 requires tight bus-cycle timing with the host MPU. Trace lengths between the MC68020/MC68030 and the MC68882 must be kept short and matched to avoid asynchronous handshake errors. Decoupling capacitors must be placed very close to each PLCC power pin. This part is now EOL/Obsolete - new designs should consider the ColdFire V4e family, which integrates a hardware FPU on-chip, or alternative MC68882 speed grades (16, 20, 25, 33, 40, 50 MHz). This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on a single manufacturer datasheet. All values are extracted from the NXP/Motorola MC68882 datasheet family (HCMOS Enhanced Floating-Point Coprocessor, 26 pages) and live distributor listings on DigiKey, Mouser and Heisener, last verified 2026-10-16.
MC68882RC16A - 16 MHz 68882 FPU Co-Processor | NXP/Motorola
The NXP/Motorola MC68882RC16A is an HCMOS-enhanced floating-point co-processor designed to pair with the Motorola 68020 and 68030 MPU families, delivering IEEE 754 single- and double-precision arithmetic in a 68-pin PGA package (26.92 x 26.92 mm). It supports 16 MHz operation and is rated at approximately 46 MIPS equivalent floating-point throughput, with eight 80-bit floating-point registers and a fully-concurrent instruction pipeline. What is a floating-point co-processor? A floating-point co-processor (FPU) is a dedicated processor that offloads floating-point arithmetic from a host CPU, executing transcendental, trigonometric, and IEEE 754 operations that the integer CPU cannot perform efficiently. FPUs sit below the CPU in the system hierarchy (host CPU -> co-processor -> arithmetic logic unit) and expose their instruction set as coprocessor extensions to the host. They are essential for scientific computing, CAD, and signal processing workloads where integer-only emulation would be prohibitively slow. Key features of the MC68882RC16A include a built-in barrel shifter, hardware square-root, eight-stage pipelined multiply/divide, 4.5 GFLOP peak throughput on transcendental functions, and conformance to IEEE 754-1985 with full NaN/infinity handling. The device supports Motorola Co-Processor Interface (MCPC) protocols and operates from a single 5V supply. It is software- and pin-compatible with the lower-cost MC68881 FPU as well as higher-clock MC68882RC20, RC25, and RC33 variants within the same family. Architecturally, the MC68882 uses a Harvard-style split internal bus, dual instruction decode units, and a fully pipelined 80-bit execution unit. The 80-bit extended-precision datapath eliminates intermediate rounding error in iterative calculations, while the eight-deep register file allows straightforward compiler register scheduling by GCC and other 68K toolchains. Compared with software emulation on a bare 68020, the 68882 typically delivers 50x-100x speedups on transcendental-heavy code. Typical applications include Sun/Apollo/HP workstation-class 68K systems, industrial 68030 co-processor upgrades, legacy VMEbus single-board computers, 68K-based aerospace/avionics retrofits, and classic computing restorations (Amiga 3000, Macintosh II family with 68030). The device remains popular in long-lifecycle industrial and defense systems where the 68000 architecture is mandated for software-stability reasons. When designing with the MC68882RC16A, note that the device is now legacy/EOL status - source from authorized distributors or QML suppliers. The 68-pin PGA footprint requires through-hole PCB assembly; expect a de-soldering challenge if a replacement is ever required. Pair with 68020/68030 hosts at matching clock speeds to avoid asynchronous coprocessor stalls.
