TMS320C6745CPTP3

Digital Signal Processor Dsp Overview

The TMS320C6745CPTP3 is a fixed- and floating-point digital signal processor based on the TMS320C674x VLIW DSP core. It operates at maximum clock frequencies of 375 MHz (1.2V) or 456 MHz (1.3V). The device features a two-level cache architecture comprising 32KB L1 Program RAM/Cache, 32KB L1 Data RAM/Cache, and 256KB unified L2 mapped RAM/cache. It includes an Enhanced Direct Memory Access Controller 3 (EDMA3) with 32 independent channels. Key peripherals include a 10/100 Mbps Ethernet MAC, three UARTs, two SPIs, two I2C interfaces, and two Multichannel Audio Serial Ports (McASP). The component is housed in a 176-pin HLQFP package.
