NXP Semiconductors DSP56321VF200R2

Overview

DSP56321VF200R2 from Freescale Semiconductor is a 24-bit digital signal processor (DSP) with a DSP56300 core, delivering 275 MMACS (550 MMACS with EFCOP), operating at 275 MHz internal clock, 1.6 V core / 3.3 V I/O supply, and integrated 192 K × 24-bit RAM - used in wireless infrastructure, echo-cancellation systems, and IP telephony.

For engineers reviewing the DSP56321VF200R2 datasheet, DSP56321VF200R2 pinout, DSP56321VF200R2 application, or DSP56321VF200R2 equivalent, key selection criteria include EFCOP-accelerated FIR/IIR filtering capability, MAP-BGA-256 package compatibility, 24-bit parallel MAC architecture, and HI08/ESSI/SCI peripheral integration for multi-channel audio and telecom signal processing.

Technical Context

The DSP56321VF200R2 implements a fully pipelined 24 × 24-bit MAC with dual 56-bit accumulators and a 56-bit barrel shifter, supporting real/complex FIR, DF-I/DF-II IIR, and adaptive LMS filtering in its dedicated EFCOP coprocessor - all running in parallel with the main core without throughput penalty. Its PLL supports skew-eliminated clock generation and dynamic divide-factor adjustment without loss of lock.

Memory architecture includes programmable allocation across 32–112 K × 24-bit program RAM, 40–80 K × 24-bit X/Y data RAM, and 1024 × 24-bit instruction cache - configurable via MSW[2:0] bits - while external expansion supports up to 256 K × 24-bit data and 256 K × 24-bit program memory spaces using Port A's 18-bit address and 24-bit data bus.

FAQ

What is the maximum operating frequency and power supply configuration for the DSP56321VF200R2?

The DSP56321VF200R2 operates at a maximum internal clock frequency of 275 MHz. It requires two independent power domains: 1.6 V ± 0.1 V for the core logic (VCCQL) and 3.3 V ± 0.3 V for all I/O interfaces (VCCQH, VCCA, VCCD, VCCC, VCCH, VCCS). Proper decoupling per power rail is mandatory to meet AC timing specifications and prevent voltage droop during EFCOP-intensive bursts.

Does the DSP56321VF200R2 support pin-compatible replacement with other DSP56300 family members?

Yes, the DSP56321VF200R2 is explicitly documented as pin-compatible with DSP56303, DSP56L307, DSP56309, and DSP56311 in the official Freescale Technical Data Rev. 11. All share the same MAP-BGA-256 package, identical Port A/B/C/D/E signal mapping, and compatible power/ground/ball assignment - enabling drop-in substitution where EFCOP and memory requirements align.

How does the EFCOP in the DSP56321VF200R2 accelerate filtering operations without impacting main core throughput?

The EFCOP in the DSP56321VF200R2 operates fully in parallel with the main DSP56300 core, sharing no execution resources. It runs at the same 275 MHz clock, accepts filter coefficients and data via dedicated internal buses, and returns results asynchronously - allowing the core to continue program execution, DMA transfers, and interrupt servicing without stalling or arbitration overhead.

What memory configuration options are available for program and data RAM in the DSP56321VF200R2?

The DSP56321VF200R2 supports eight programmable memory maps controlled by MSW[2:0] bits. Configurations range from 32 K × 24-bit program RAM + 80 K × 24-bit X/Y RAM (instruction cache disabled) to 112 K × 24-bit program RAM + 40 K × 24-bit X/Y RAM (cache enabled), with 12 K × 24-bit shared memory accessible by both core and EFCOP - enabling trade-offs between code footprint, data buffering, and cache performance.

Which serial interfaces does the DSP56321VF200R2 provide for audio and communications connectivity?

The DSP56321VF200R2 integrates three serial interfaces: HI08 (8-bit parallel host interface), dual ESSI ports (each with 1 Rx + 3 Tx channels supporting 6-channel audio), and SCI (asynchronous UART with baud rate generator). These enable glueless connection to codecs, microcontrollers, and network processors - with ESSI0/ESSI1 capable of simultaneous 6-channel PCM output for home theater systems.
