TMS320C6726RFP250

Digital Signal Processor Dsp Overview

The TMS320C6726RFP250 is a floating-point digital signal processor from the C672x family, operating at a maximum frequency of 250 MHz. It features an enhanced C67x+ CPU capable of executing up to eight instructions per cycle for performance up to 2400 MIPS and 1800 MFLOPS. The device integrates 256 Kbytes of unified program/data RAM and 384 Kbytes of ROM within a 144-pin PowerPAD Thin Quad Flatpack (TQFP) package. Key peripherals include three Multichannel Audio Serial Ports (McASP), two SPI ports, two I2C ports, and a Real-Time Interrupt timer.

Digital Signal Processor Dsp Feature Summary

• Enhanced C67x+ CPU with 64 general-purpose registers and support for 32-bit fixed-point and single/double-precision floating-point arithmetic
• Integrated memory system comprising 256K-byte unified RAM and 384K-byte unified ROM with a 32K-byte program cache
• Three Multichannel Audio Serial Ports (McASP) supporting I2S and TDM formats with dedicated DMA bus
• Dual Data Movement Accelerator (dMAX) for concurrent data transfers between memory and peripherals

Digital Signal Processor Dsp Applications

• Professional audio processing and mixing
• Audio effects boxes and synthesis
• Instrument and amplifier modeling
• Audio conferencing systems

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix '250' corresponds to the required 250 MHz operational frequency. Confirm the 'RFP' suffix indicates the 144-pin Green TQFP PowerPAD package. Ensure compliance with RoHS standards as indicated in production data documentation.

Digital Signal Processor Dsp Selection Notes

Select this model when a 250 MHz clock speed is sufficient for the application, offering a cost-effective alternative to the 300 MHz C6727 variant. The 16-bit EMIF width is suitable for standard SDRAM interfaces. Verify that the peripheral set, including the absence of UHPI, meets the system's connectivity requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C672x series, which includes the C6727, C6726, and C6722. The C6726 serves as an intermediate option between the higher-performance C6727 and the lower-cost C6722, sharing the same core architecture and memory configuration but differing in maximum clock frequency and external interface width.

Digital Signal Processor Dsp Replacement Considerations

Direct functional replacements within the same family include the TMS320C6727RFP300 (300 MHz) and TMS320C6722RFP200 (200 MHz). These variants share pinouts and software compatibility but differ in performance specifications and EMIF data width.
