NXP Semiconductors XC56L307VL150

Overview

XC56L307VL150 from Freescale Semiconductor is a 24-bit digital signal processor (DSP) in the DSP56300 family, designed for high-throughput network and wireless infrastructure applications. It delivers 160 MMACS core performance (320 MMACS with EFCOP), features 192 K × 24-bit on-chip RAM (configurable as 16 K program RAM + 1024-word instruction cache + 24 K X/Y data RAM), operates at 160 MHz internal clock with 1.8 V core / 3.3 V I/O, and integrates an Enhanced Filter Coprocessor for parallel echo cancellation and FIR/IIR filtering.

For engineers reviewing the XC56L307VL150 datasheet, XC56L307VL150 pinout, XC56L307VL150 application, or XC56L307VL150 equivalent, key selection criteria include EFCOP-accelerated filtering throughput, configurable memory mapping, 6-channel DMA support, PLL-based clock generation with skew elimination, and compatibility with legacy DSP56000 code for migration from earlier Freescale DSP platforms.

Technical Context

The XC56L307VL150 implements a fully pipelined DSP56300 core with 24×24-bit MAC, 56-bit barrel shifter, and position-independent code support. Its dual-bus architecture separates program and data paths, enabling simultaneous instruction fetch and operand access - critical for real-time filtering and multi-channel telephony processing.

The integrated Enhanced Filter Coprocessor (EFCOP) runs filter algorithms-including real/complex FIR, DF1/DF2 IIR, and adaptive LMS-concurrently with the main core at full 160 MHz speed. Memory configuration is controlled via MSW0/MSW1 bits, allowing dynamic allocation of up to 47 K × 24-bit program RAM and 20 K × 24-bit X/Y data RAM, with 4 K × 24-bit shared between core and EFCOP.

Key Specifications

Pinout & Package

XC56L307VL150 is housed in a molded array plastic-ball grid array (MAP-BGA) package. Pin assignments follow the standard DSP56300 family layout with dedicated buses (XAB/XDB, YAB/YDB, PAB/PDB), peripheral interfaces (ESSI, SCI, HI08), and control signals (RESET, INIT/NMI, EXTAL/XTAL).

FAQ

What is the maximum operating frequency of the XC56L307VL150?

The XC56L307VL150 operates with an internal 160 MHz clock derived from its integrated PLL. This frequency drives both the main DSP core and the Enhanced Filter Coprocessor (EFCOP), enabling synchronous execution of core instructions and parallel filter operations. The device maintains full 160 MMACS core performance and achieves 320 MMACS aggregate throughput when EFCOP is active - verified in Freescale's DSP56L307 Product Brief Rev. 2.

Does the XC56L307VL150 support external memory expansion?

Yes, the XC56L307VL150 supports external memory expansion via dedicated address and data buses. It can expand data memory to two 256 K × 24-bit spaces and program memory to one 256 K × 24-bit space. Integrated chip-select logic enables glueless interface to SRAM, and an on-chip DRAM controller supports DRAMs up to 100 MHz - all documented in the XC56L307VL150 Technical Data manual.

How does the Enhanced Filter Coprocessor (EFCOP) in the XC56L307VL150 improve system performance?

The EFCOP in the XC56L307VL150 executes FIR, IIR, and adaptive LMS filtering algorithms concurrently with the main DSP core at full 160 MHz speed. This offloads computationally intensive signal conditioning tasks - such as echo cancellation in VoIP gateways - freeing the core for protocol stack and control functions. As a result, XC56L307VL150 achieves 320 MMACS aggregate throughput without increasing latency or reducing channel count.

What debugging capabilities does the XC56L307VL150 provide?

The XC56L307VL150 includes the OnCE™ (On-Chip Emulation) module with JTAG test access port (TAP), enabling non-intrusive real-time debugging. Engineers can perform cycle-accurate tracing, set hardware breakpoints, inspect registers and memory, and control execution flow without halting real-time signal processing - a capability confirmed in the XC56L307VL150 User's Manual and Product Brief.

Is the XC56L307VL150 pin-compatible with other DSP56300 family members?

The XC56L307VL150 uses the same MAP-BGA package footprint and signal naming convention as other high-pin-count DSP56300 devices like XC56L305VL150 and XC56L309VL150, but pin assignments differ due to peripheral enablement and memory mapping options. While electrical signaling and bus structures are consistent, direct pin-to-pin replacement requires verification of peripheral usage and MSW configuration - as detailed in the XC56L307VL150 datasheet pinout diagrams.
