NXP Semiconductors XC56L307VF160

Overview

XC56L307VF160 from Freescale Semiconductor is a 24-bit digital signal processor (DSP) designed for high-throughput network infrastructure applications. It delivers up to 160 MMACS (320 MMACS with EFCOP acceleration), operates at 160 MHz core clock, features 192 K × 24-bit on-chip RAM (configurable as 16 K program RAM + 24 K X/Y data RAM + 1024-word instruction cache), and integrates an Enhanced Filter Coprocessor (EFCOP) for parallel echo cancellation and FIR/IIR filtering in wireless base stations.

For engineers reviewing the XC56L307VF160 datasheet, XC56L307VF160 pinout, XC56L307VF160 application, or XC56L307VF160 equivalent, this page provides verified technical context, memory configuration options, EFCOP filter mode support, external bus timing constraints, and lead-free MAP-BGA package details required for telecom DSP board design and migration from legacy DSP56300 platforms.

Technical Context

The XC56L307VF160 implements the DSP56300 core architecture with full DSP56000 object-code compatibility, a fully pipelined 24×24-bit MAC unit, dual 56-bit accumulators, and a 56-bit barrel shifter. Its six-channel DMA supports 1D/2D/3D transfers and circular buffering, triggered by peripherals or interrupts.

It embeds a dedicated EFCOP coprocessor running synchronously at 160 MHz, supporting real/complex FIR, DF1/DFII IIR, adaptive LMS filters, and 4-bit decimation - all executing concurrently with core instructions without throughput penalty. Memory mapping is controlled via MSW0/MSW1 bits to allocate RAM between program, X/Y data, and instruction cache spaces.

Supply support for XC56L307VF160 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) specialized in high-performance embedded processors for automotive, industrial, and communications markets before its 2015 acquisition.

The XC56L307VF160 belongs to the DSP56300 family, engineered specifically for telecom infrastructure requiring deterministic real-time filtering, multi-protocol serial connectivity, and scalable memory architecture - not general-purpose computing.

FAQ

What is the maximum operating frequency of the XC56L307VF160 core?

The XC56L307VF160 operates with an internal 160 MHz core clock, enabled by its integrated PLL. This frequency is sustained under 1.8 V core supply and ambient temperatures up to 85°C. External bus signals (CLKOUT, BCLK, CAS, RAS) are limited to 100 MHz operation - exceeding this violates timing specifications for DRAM access and external synchronization.

Does the XC56L307VF160 support external memory expansion beyond on-chip RAM?

Yes, the XC56L307VF160 supports external memory expansion via its 18-bit address bus (A[0–17]) and 24-bit data bus (D[0–23]). It can access two 256 K × 24-bit data memory spaces and one 256 K × 24-bit program memory space. The integrated DRAM controller supports glueless interface to DRAMs up to 100 MHz, and chip select logic enables direct connection to SRAMs.

How does the Enhanced Filter Coprocessor (EFCOP) in the XC56L307VF160 improve system-level performance?

The EFCOP in the XC56L307VF160 executes echo cancellation, FIR, and IIR filtering algorithms in parallel with the main DSP core - delivering up to 320 MMACS aggregate throughput without consuming core cycles. This allows the core to handle protocol stacks, control tasks, and interrupt servicing while EFCOP manages real-time signal conditioning, increasing effective channel density by 2× in base station applications.

What power supply requirements must be met for reliable operation of the XC56L307VF160?

The XC56L307VF160 requires seven independent power domains: 1.8 V for core logic (VCCQL), 3.3 V for I/O (VCCQH), and isolated 3.3 V supplies for address bus (VCCA), data bus (VCCD), bus control (VCCC), host interface (VCCH), and serial peripherals (VCCS). Each domain needs dedicated decoupling capacitors; VCCP (PLL power) must be well-regulated with a 0.47 µF capacitor tied to GNDP.

Is the XC56L307VF160 pin-compatible with other devices in the DSP56300 family?

No, the XC56L307VF160 uses a 160-ball MAP-BGA package unique to this variant. While functionally compatible with the DSP56300 instruction set and sharing peripheral architecture with devices like DSP56309 or DSP56367, its pinout differs due to expanded memory interface signals, dedicated EFCOP control lines, and isolated power/ground ball allocation - requiring PCB redesign for migration from other family members.
