DSP56858VF120 概要
A Digital Signal Controller (DSC) is a hybrid class of microcontroller that combines a microcontroller's on-chip peripherals and interrupt-driven control flow with a digital signal processor's parallel multiply-accumulate (MAC) datapath and single-cycle instruction execution. In the broader taxonomy, a DSC sits between a general-purpose microcontroller (MCU), a dedicated digital signal processor (DSP), and a microcontroller-with-DSP-instructions. The DSP5685x family targets cost-sensitive embedded control applications requiring deterministic signal processing without the overhead of a larger 32-bit DSP core.
Key features of the DSP56858VF120 include a 16-bit modified Harvard core with 16-bit Program SRAM, 16-bit Data SRAM, 16-bit Boot ROM, chip-select logic for glue-less interface to external ROM and SRAM, six independent DMA channels, two Enhanced Synchronous Serial Interfaces (ESSI), and industrial-grade temperature support. The architecture provides direct access to up to 2 Mwords of program memory or 8 Mwords of data memory, enabling code density for audio decoding, motor-control algorithms, and protocol-stack processing.
Typical applications include digital motor control (BLDC/PMSM), voice-band audio processing, low-rate speech codecs, secure transaction terminals, industrial sensor conditioning, and digital audio consumer products. Its 120 MIPS core delivers headroom for FOC (field-oriented control) loops and VFD/SVC codecs within a single device.
When designing with the DSP56858VF120, plan for memory-mapped external flash because the on-chip SRAM is limited; configure the chip-select logic to match the timing of any external memory, and ensure proper decoupling on the analog supply pins.

主な用途
DSP56858VF120 の用途: 6 件s: Three-Phase Motor Control (BLDC/PMSM), Voice-Band Audio Codec DSP, Industrial Sensor Signal Conditioning, Digital Audio Consumer Products, Secure Transaction Terminals, DSP/Algorithm Educational Boards.
Three-Phase Motor Control (BLDC/PMSM)
The DSP56858VF120's 120 MIPS 56800 core and six DMA channels handle field-oriented control (FOC) loops for industrial BLDC and PMSM drives within a single device. Industrial temperature grade and chip-select glue-less external memory support firmware scaling beyond on-chip SRAM, while the two ESSI ports isolate encoder feedback from the regulation loop. Drop into a 144-ball MAP-LBGA land pattern identical to the larger 56858 family, lowering PCB layout risk.
おすすめ
Voice-Band Audio Codec DSP
At 120 MIPS, DSP56858VF120 decompresses G.711/G.729 and other narrow-band voice codecs in real time, and the two Enhanced Synchronous Serial Interfaces (ESSI) stream PCM samples directly to codecs such as the MSC8144-class audio DAC. Its on-chip 16-bit Data SRAM and glue-less chip-select external memory interface let firmware interleave in-RAM coefficient tables with on-chip boot ROM functions. The 144-ball MAP-LBGA package survives industrial temperature corners required for outdoor intercom or paging hardware.
おすすめ
Industrial Sensor Signal Conditioning
Sensor-front-end boards use the DSP56858VF120 to decimate and filter 16-bit ADC streams from industrial transducers ahead of higher-level control loops. Six DMA channels keep ADC bursts fed without core stalls, while the chip-select logic lets designers attach async SRAM capture buffers at predictable wait-state budgets. Its industrial temperature grade and LBGA package meet harsh-environment reliability expectations for factory-floor sensor hubs.
おすすめ
Digital Audio Consumer Products
The DSP56858VF120 powers effects processing and sample-rate conversion in consumer digital-audio equipment such as karaoke mixers and DJ controllers that demand deterministic audio latency. Its six DMA channels handle bi-directional streaming between USB-class audio sources and the ESSI link to the CODEC, leaving MIPS headroom for reverb and EQ algorithms. Designers value the legacy toolchain (CodeWarrior 56800 / GNU 56800-gcc) which is well-supported for low-cost effect DSP production.
おすすめ
Secure Transaction Terminals
EMV-style payment terminals leverage the DSP56858VF120's deterministic execution and glue-less external memory interface to host encrypted PIN-pad firmware in external secure flash with on-chip code checksum verification at boot. The Harvard-style 16-bit core resists speculative-side-channel timing attacks better than pipelined superscalar cores, and the LBGA package supports tamper-detection grid layouts. Industrial temperature grade suits outdoor vending and unattended kiosk deployments.
おすすめ
DSP/Algorithm Educational Boards
University DSP lab kits adopt the DSP56858VF120 because of its well-documented ISA, freely available assembler tutorials, and pin-pin compatibility with slower 5685x siblings for performance benchmarking. The Harvard bus and deterministic interrupt latency make it ideal for teaching pipelining, MAC, and saturating-arithmetic concepts; the LBGA package remains manageable on 4-layer evaluation PCBs. GNU binutils-56800 is widely deployed in academic settings.

主な差別化要因

設計ノート
Estimated: at 120 MHz continuous load with typical 56858 process, core power dissipation lands near 600 mW with 1.8/2.5 V rails. The MAP-LBGA-144 has a small top-side heat-spreader footprint, so provide at least four thermal vias in the central power/ground balls and couple to an internal copper pour to keep junction rise acceptable in enclosed industrial enclosures.
The 144-ball LBGA at 1.0 mm pitch demands laser-cut SMT stencils and no-clean Type 4 solder paste; reflow with a ramp rate of 2 to 3 C/s up to peak 245 C to avoid tombstoning. Place four 100 nF X7R bypass capacitors adjacent to the four power-supply balls, and route the 50 ohm-controlled clock trace within 5 mm of the XTAL ball to keep EMI under control.
Estimated: design teams migrating from 5685x to MCF51JE or S912X cores must rewrite the vector table and revalidate interrupt-priority mappings because the ColdFire/S12 interrupt controllers differ in nesting priority order. Also, when using DMA with peripherals, ensure the ESSI baud-rate generator is not clocked above 30 MHz or DMA overruns occur under bursts - this rate is derived rather than verbatim from a datasheet figure.
コンプライアンス情報
RoHS/REACH compliance not surfaced in distributor datasheets; the original Freescale 56858 family predates full RoHS documentation. Verify against the manufacturer datasheet before shipping to markets requiring proof of substance compliance.
