250 MHz floating-point engine for real-time control
The SM320C6727BGDHMEP: This is a floating-point DSP from the TMS320C672x series, clocked at 250 MHz. The floating-point core handles the wide dynamic range of sensor fusion, audio processing, or servo control loops without the scaling overhead of a fixed-point part — the 250 MHz ceiling sets the real-time throughput for the algorithm, not just the instruction rate. On-chip memory consists of 288 kB RAM and 384 kB ROM. For many control applications this is enough to hold the program and data buffers without external memory, though the EBI/EMI interface is available if the application needs more.
Peripheral set and supply rails
The peripheral interface includes EBI/EMI, HPI, I²C, McASP, and SPI. The McASP (Multichannel Audio Serial Port) is the natural fit for audio codec or digital microphone arrays; the HPI (Host Port Interface) lets an external host processor access the DSP's memory directly without arbitration overhead. Dual supply: core at 1.20 V, I/O at 3.30 V. The separate I/O rail means the DSP can interface directly with 3.3 V logic peripherals without external level translation on most signals.
Temperature grade and board integration
Rated for -55°C to 125°C case temperature — this is the extended industrial/military band. The part is suited for avionics, downhole instrumentation, or engine-bay control modules where commercial-grade silicon would drift out of spec. Packaged in a 256-ball BGA, 17x17 mm body. The 1.00 mm ball pitch is layout-friendly — a standard 4-layer PCB with via-in-pad or dogbone fan-out handles the routing.
Compliance and documentation
ROHS3 compliant. Texas Instruments provides the datasheet, application notes, and PCN notifications through their standard documentation portal.
