NXP Semiconductors XC56309VF100AR2

Overview

XC56309VF100AR2 from Freescale Semiconductor is a 24-bit programmable digital signal processor (DSP) based on the DSP56300 core, delivering 100 MMACS at 100 MHz with 3.3 V supply, featuring 20,480 × 24-bit program RAM, dual 7,168 × 24-bit X/Y data RAM, and integrated six-channel DMA. It targets wireless infrastructure baseband processing where large on-chip memory reduces external bus contention.

For engineers reviewing the XC56309VF100AR2 datasheet, XC56309VF100AR2 pinout, XC56309VF100AR2 application, or XC56309VF100AR2 equivalent, key selection criteria include internal memory configuration flexibility, PLL-based clock synthesis with skew elimination, OnCE™ debug support, ESSI/SCI peripheral integration, and TQFP-144 packaging for high-density RF subsystems.

Technical Context

The XC56309VF100AR2 implements the full DSP56300 instruction set with position-independent code support, nested DO loops, and fast auto-return interrupts. Its data path includes a fully pipelined 24×24-bit MAC unit feeding two 56-bit accumulators and a 56-bit barrel shifter for normalization and bit-stream operations.

Memory architecture supports dynamic allocation across program, X-data, and Y-data spaces - default configuration allocates 20,480 × 24-bit program RAM, 7,168 × 24-bit X RAM, and 7,168 × 24-bit Y RAM, all accessible without wait states. The external bus interface enables glueless expansion to 256 K × 24-bit data and program memory spaces via dedicated address/data buses.

FAQ

What is the maximum operating frequency of the XC56309VF100AR2?

The XC56309VF100AR2 operates at a maximum internal clock frequency of 100 MHz, achieved via its integrated PLL using an external 10 MHz crystal reference. This yields 100 million multiply-accumulates per second (MMACS) at 3.3 V supply, with timing validated across commercial temperature range (0°C to 70°C). The XC56309VF100AR2 maintains full functionality down to 0 Hz in static mode, supporting ultra-low-power standby.

Does the XC56309VF100AR2 support external memory expansion?

Yes, the XC56309VF100AR2 supports external memory expansion through dedicated buses: two 256 K × 24-bit data memory spaces and one 256 K × 24-bit program memory space. Its chip select logic and integrated DRAM controller enable glueless interface to SRAM and SDRAM, eliminating need for address latches or bus transceivers. The XC56309VF100AR2 retains full DMA and interrupt support during external memory accesses.

How many general-purpose I/O pins does the XC56309VF100AR2 provide?

The XC56309VF100AR2 provides up to thirty-four programmable general-purpose input/output (GPIO) pins, with actual count dependent on peripheral enable configuration. Pins shared with MOD/IRQ functions or ESSI/SCI signals become unavailable when those peripherals are active. All GPIOs support configurable pull-up/down and interrupt-on-change capability, and the XC56309VF100AR2 allows runtime reassignment via peripheral control registers.

What debug capabilities does the XC56309VF100AR2 include?

The XC56309VF100AR2 integrates the OnCE™ (On-Chip Emulation) module with JTAG TAP, enabling non-intrusive real-time debugging, hardware breakpoints, watchpoint triggers, and register visibility without halting execution. It supports full instruction trace and memory access monitoring, and the XC56309VF100AR2 is compatible with Freescale's CodeWarrior DSP tools for source-level development and profiling.

Is the XC56309VF100AR2 RoHS-compliant?

Yes, the XC56309VF100AR2 is offered in both lead-free (RoHS-compliant) and lead-bearing versions, as confirmed in the Freescale DSP56309 Product Brief Rev. 1. The "VF" suffix denotes lead-free TQFP packaging, and the device meets JEDEC J-STD-020 moisture sensitivity level 3. The XC56309VF100AR2 requires standard Pb-free reflow profiles and is qualified for industrial temperature operation.
