Product details
Overview
DSP56858FVE from NXP Semiconductors (formerly Freescale) is a 16-bit Digital Signal Controller integrating a 56800E DSP core with microcontroller peripherals. It delivers 120 MIPS at 120 MHz, features 40K × 16-bit program SRAM, 24K × 16-bit data SRAM, and 1K × 16-bit boot ROM, and supports up to 47 GPIOs - enabling real-time audio processing in voice recognition systems.
For engineers reviewing the DSP56858FVE datasheet, DSP56858FVE pinout, DSP56858FVE application, or DSP56858FVE equivalent, key selection considerations include its dual Harvard architecture, six-channel DMA, two ESSI modules for synchronous serial audio interfaces, and 144-pin LQFP package compatibility with industrial teledatacom and embedded voice control designs.
Technical Context
The DSP56858FVE implements a parallel-execution 56800E core with three address buses and four data buses, enabling up to six operations per instruction cycle. Its dual Harvard memory architecture permits simultaneous access to program and data memory, supporting real-time loop execution via hardware DO/REP loops and four 36-bit accumulators.
Peripheral integration includes two Enhanced Synchronous Serial Interfaces (ESSI0/ESSI1) with configurable frame sync and clock gating, two SCIs, one SPI, an 8-bit parallel host interface, and a 16-bit quad timer - all multiplexed with GPIO functionality and controlled via dedicated chip select logic for glue-less external memory expansion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital signal controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DSP56F807FVM | Same 56800E core, but 64-pin LQFP; reduced memory (16K/8K SRAM); no ESSI; only one SCI | Limited to simpler motor control or basic audio preprocessing where dual ESSI and large RAM are unnecessary | Select when board space and BOM cost are critical and full DSP56858FVE peripheral set is unused |
| TMS320F28027PTT | 32-bit C28x core; higher 60 MHz CPU clock; 32K flash; no boot ROM; different peripheral mix (ePWM, ADC focus) | Better suited for real-time motor control than audio signal processing due to lack of ESSI and optimized serial audio support | Prefer for industrial motor drives; avoid for legacy 56800E codebase migration or audio-centric designs requiring ESSI |
Compared with DSP56858FVE, DSP56F807FVM offers footprint and cost reduction at the expense of audio interface capability and memory headroom, while TMS320F28027PTT shifts focus toward control-oriented peripherals and lacks native synchronous serial audio infrastructure.

FAQ
What is the maximum operating frequency of the DSP56858FVE?
The DSP56858FVE operates at a maximum core frequency of 120 MHz, delivering 120 MIPS performance. This speed is achieved using an internal PLL that multiplies the external crystal oscillator input, and it is fully supported across the specified industrial temperature range (–40°C to +105°C) with appropriate VDD and VDDIO supply conditions.
Does the DSP56858FVE include on-chip non-volatile memory for boot code?
Yes, the DSP56858FVE includes 1K × 16-bit boot ROM, which contains factory-programmed initialization routines and bootstrap code. This ROM is used during power-on reset to configure the device before loading application code from external memory or internal SRAM, eliminating the need for external boot PROM in many designs.
How many independent serial audio interfaces does the DSP56858FVE support?
The DSP56858FVE supports two independent Enhanced Synchronous Serial Interfaces (ESSI0 and ESSI1), each with full transmit/receive capability, frame sync, serial clock, and three configurable control pins. These interfaces can be configured for I²S, left-justified, right-justified, or custom TDM formats - enabling simultaneous stereo capture and playback.
Can the DSP56858FVE execute code directly from external memory?
Yes, the DSP56858FVE supports direct execution from external memory via its 21-bit address bus and 16-bit data bus, with dedicated chip select outputs (CS0–CS3) and glue-less interface logic. External program memory up to 2M words is accessible, and the device automatically manages wait states based on external memory timing parameters.
What debug interface does the DSP56858FVE provide for firmware development?
The DSP56858FVE integrates JTAG/Enhanced On-Chip Emulation (OnCE™), providing non-intrusive, real-time debugging with full visibility into core registers, memory, and peripheral states. This interface supports breakpoints, watchpoints, and live trace without halting system timing - essential for tuning real-time audio algorithms.
