The dual-mode arithmetic unit handles both fixed-point and floating-point math in a single core, so a single device serves control loops that need fixed-point determinism and audio/imaging pipelines that want floating-point dynamic range. On-chip memory totals 488 kB of RAM plus 1.088 MB of ROM. The RAM is split across and cache and SRAM configurable regions — enough to hold a real-time audio buffer or a motor-control frame without external memory for many embedded signal chains. The ROM carries boot code and fixed algorithm tables; the 1.088 MB figure is the factory-programmed mask ROM, not flash. Core voltage options span 1.00 V, 1.10 V, and 1.20 V, letting the designer trade power dissipation against maximum operating frequency. Running at 1.00 V core drops dynamic power but may limit the top clock rate; 1.20 V core is the high-performance bias. The I/O voltage is split between 1.8 V and 3.3 V banks, so the device interfaces directly with both low-voltage serial peripherals and legacy 3.3 V logic without external level shifters on most pins. ## Temperature grade and environment A motor drive in a non-conditioned cabinet, an outdoor telecom baseband card, or an engine-bay ECU that sees 85°C ambient on a summer day still has margin before the junction hits the 105°C ceiling. The 361-NFBGA package (13x13 mm,) is the fine-pitch ball-grid array variant — the 0.65 mm ball pitch demands a 4-layer PCB minimum for fan-out; two-layer boards will struggle to route the inner rows. ## Peripheral set and system integration The peripheral mix includes an Ethernet MAC, a host interface, EBI/EMI for external memory or FPGA glue, plus I²C, SPI, UART, McASP, and McBSP serial ports. The Ethernet MAC is a 10/100 MII/RMII interface — no switch or PHY integrated, so an external PHY chip with the magnetics is needed for the physical connection. The McASP port streams up to 16 serial data pins for multichannel audio or high-speed ADC capture; the McBSP is the legacy codec-compatible serial port. The EBI/EMI interface connects to asynchronous or synchronous external memory (NOR flash, NAND flash, SRAM) without an FPGA between. The host interface lets an external microcontroller or application processor access the DSP's memory map as a slave device — useful when the DSP is a coprocessor for signal processing and the main CPU handles the UI and networking stack. ## Lifecycle and sourcing posture The 361-NFBGA package is the standard production variant — no package-change PCN is expected for this active code.","metaTitle":"TMS320C6746EZCEA3 Fixed/Floating Point DSP, 375 MHz","metaDescription":"Texas Instruments TMS320C6746EZCEA3 Fixed/Floating Point DSP, 375 MHz clock, 488 kB RAM, 1.088 MB ROM, -40 to 105°C.
