Texas Instruments TMS320VC5509APGE

Overview

TMS320VC5509APGE from Texas Instruments is a fixed-point digital signal processor (DSP) featuring a 16-bit CPU core, 32-bit internal data bus, 128K × 16-bit on-chip RAM, 16M-word address space, and integrated peripherals including six-channel DMA, three 32-bit timers, and McBSP serial ports. It targets real-time audio processing in portable voice recorders and telephony endpoint devices.

For engineers reviewing the TMS320VC5509APGE datasheet, TMS320VC5509APGE pinout, TMS320VC5509APGE application, or TMS320VC5509APGE equivalent, key selection considerations include its 144-pin LQFP package, 12.5-ns instruction cycle time at 200 MHz CPU clock, 1.6-V core supply requirement, and support for external memory expansion via EMIF with 16-bit data bus width.

Technical Context

The TMS320VC5509APGE implements TI's C55x DSP architecture with dual-MAC, four-function ALU, and parallel execution of arithmetic and memory operations. It supports zero-overhead looping, conditional execution, and barrel shifting - enabling efficient implementation of FIR/IIR filters and FFT kernels.

Its memory subsystem includes 32K words of on-chip ROM (bootloader), 64K words of DARAM, and 64K words of SARAM, all accessible in single-cycle operation. The EMIF supports asynchronous SRAM, EPROM, and SDRAM interfaces with programmable wait-state control and chip-select timing.

FAQ

What is the maximum operating frequency of the TMS320VC5509APGE?

The TMS320VC5509APGE operates at a maximum CPU clock frequency of 200 MHz, achieving 400 million instructions per second (MIPS). This performance level is sustained under 1.6-V core supply and ambient temperatures up to 85°C. The internal PLL multiplies an external 10-MHz reference clock to generate the 200-MHz core clock. The TMS320VC5509APGE datasheet specifies timing margins for all internal buses and peripherals at this frequency.

Does the TMS320VC5509APGE support external SDRAM?

Yes, the TMS320VC5509APGE supports external SDRAM through its External Memory Interface (EMIF) with programmable timing registers. It requires external address multiplexing and control logic (e.g., TI's TSB12LV23 or discrete logic) to manage row/column addressing and refresh cycles. The TMS320VC5509APGE EMIF does not integrate SDRAM controller logic, so system-level design must implement refresh arbitration and bank management.

What development tools are officially supported for the TMS320VC5509APGE?

Texas Instruments officially supports Code Composer Studio v3.3 and later for the TMS320VC5509APGE, along with the XDS510-class JTAG emulators and the TMDSEVM5509 evaluation module. The TMS320VC5509APGE-specific compiler (C55x C/C++ Compiler v4.4.0) and DSP/BIOS real-time kernel are validated for use with this device. TI provides device-specific header files, linker command files, and peripheral driver libraries in the C55x IQMath library.

Can the TMS320VC5509APGE execute code from external Flash memory?

Yes, the TMS320VC5509APGE can execute code from external Flash memory mapped into its 16-Mword address space via the EMIF. Boot mode configuration (using GPIO pins at reset) determines whether the device boots from on-chip ROM or external memory. The TMS320VC5509APGE supports 8-bit and 16-bit Flash devices with configurable wait states and chip-select timing - enabling reliable execution of firmware stored in parallel NOR Flash.

Is the TMS320VC5509APGE pin-compatible with other C55x family members?

No, the TMS320VC5509APGE is not pin-compatible with other C55x devices such as the TMS320VC5502 or TMS320C5515. Its 144-pin PGE package has unique signal assignments for EMIF, McBSP, and timer peripherals. While functional blocks are architecturally similar across the C55x family, pin mappings differ significantly due to varying peripheral counts and memory interface widths. Migration requires PCB redesign and firmware adaptation for the TMS320VC5509APGE.
