NXP Semiconductors XC56L307VL160

Overview

XC56L307VL160 from Freescale Semiconductor is a 24-bit digital signal processor (DSP) in the DSP56300 family, featuring a 160 MHz core clock, 1.8 V core / 3.3 V I/O supply, and an integrated Enhanced Filter Coprocessor (EFCOP). It delivers 160 MMACS (320 MMACS with EFCOP active) and targets high-channel-count network infrastructure applications requiring real-time echo cancellation and FIR/IIR filtering.

For engineers reviewing the XC56L307VL160 datasheet, XC56L307VL160 pinout, XC56L307VL160 application, or XC56L307VL160 equivalent, key selection considerations include EFCOP-supported filter modes (real/complex FIR, DF1/DF2 IIR), programmable memory partitioning (up to 192 K × 24-bit RAM), six-channel DMA, OnCE™ JTAG debug support, and MAP-BGA packaging with 160-ball layout.

Technical Context

The XC56L307VL160 implements a fully pipelined DSP56000-compatible core with dual 56-bit accumulators, 24×24-bit MAC, and 56-bit barrel shifter. Its EFCOP operates synchronously at 160 MHz and supports adaptive LMS updates, 4-bit decimation, and four IIR output scaling factors (1×–16×).

Memory architecture includes configurable X/Y/Program RAM and instruction cache (1024×24-bit), with total internal RAM up to 192 K × 24 bits - including 4 K × 24-bit shared memory accessible by both core and EFCOP. External expansion supports two 256 K × 24-bit data spaces and one 256 K × 24-bit program space via glueless SRAM/DRAM interfaces.

Key Specifications

Pinout & Package

XC56L307VL160 is housed in a 160-ball Molded Array Plastic Ball Grid Array (MAP-BGA) package with 1.0 mm ball pitch, RoHS-compliant lead-free construction. Pinout follows standard DSP56300 external bus interface layout with dedicated YAB/XAB/PAB address buses, YDB/XDB/PDB data buses, GDB global data bus, MODx/IRQx multiplexed mode/interrupt pins, and peripheral-specific signals (ESSI, SCI, HI08, timers, GPIO).

FAQ

What is the maximum operating frequency of the XC56L307VL160?

The XC56L307VL160 operates with an internal 160 MHz clock, enabling single-cycle instruction execution and delivering 160 MMACS in base mode. Its PLL supports stable clock generation at this frequency with skew elimination, and the EFCOP runs synchronously at the same 160 MHz rate to achieve 320 MMACS during parallel filter operations. This frequency is specified under 1.8 V core supply conditions.

Does the XC56L307VL160 support external memory expansion?

Yes, the XC56L307VL160 supports external memory expansion via dedicated address and data buses. It can expand data memory to two 256 K × 24-bit word spaces and program memory to one 256 K × 24-bit word space. The device includes chip select logic for glueless SRAM interfacing and an integrated DRAM controller supporting DRAMs up to 100 MHz - all documented in the DSP56L307 Technical Data manual.

How does the Enhanced Filter Coprocessor (EFCOP) in the XC56L307VL160 improve filtering performance?

The EFCOP in the XC56L307VL160 executes FIR and IIR filtering operations in parallel with the main DSP core, eliminating pipeline stalls and preserving full 160 MHz core utilization. It supports real/complex FIR, DF1/DF2 IIR, adaptive LMS updates, and 4-bit decimation - enabling XC56L307VL160 to deliver 320 MMACS for filtering workloads while the core handles control, protocol, and I/O tasks concurrently.

What debug capabilities does the XC56L307VL160 provide for firmware development?

The XC56L307VL160 integrates the OnCE™ (On-Chip Emulation) module with JTAG test access port (TAP), supporting non-intrusive real-time debugging, hardware breakpoints, register inspection, and instruction trace. This allows full visibility into XC56L307VL160 execution flow without performance impact - essential for validating time-critical DSP algorithms in telecom infrastructure applications.

Is the XC56L307VL160 pin-compatible with other devices in the DSP56300 family?

The XC56L307VL160 shares the same 160-ball MAP-BGA package and external bus interface pinout with other members of the DSP56L3xx series, including XC56L305VL160. However, functional differences - such as presence/absence of EFCOP - mean that while PCB layout may be reused, firmware and memory mapping must be validated per device. Full pin compatibility is confirmed only within the L307/L305 VL160 variant group.
