The ADSP-2146x fourth-generation SHARC^® Processors offer a high-performance core, plus application- and audio-specific peripherals, making them ideal for professional and automotive audio applications. Their single-instruction, multiple-data (SIMD) core supports 32-bit fixed-point and 32-/40-bit floating-point arithmetic formats—performing at up to 2.7 GFLOPS and 900 MMACS with a 450-MHz clock. The DMA controllers support 67 channels, each of which can transfer 32-bit serial data at peripheral clock speed without slowing processor execution. The digital audio interface (DAI) includes eight serial ports, four precision clock generators, an input data port, an S/PDIF transceiver, and a flexible signal-routing unit (SRU). The digital peripheral interface (DPI) includes two SPI ports, two timers, a UART, a DTCP cipher, and a 2-wire interface. Two 8-bit, bidirectionally programmable link ports can connect to the link ports of other DSPs or peripherals. 5 Mbits of RAM and 4 Mbits of ROM are included on-chip. The following table compares the various models.

Model/Parameter	Frequency (MHz)	ROM (bits)	Digital Content Transmission Protocol (DTCP)	Media Local Bus (MLB)	Automotive Applications	Temperature Range (°C)
ADSP-21462W	400	N/A	Yes	Yes	Yes	–40 to +85
ADSP-21465W	400	4M	Yes	Yes	Yes	–40 to +85
ADSP-21467	450	4M	No	No	No	0 to +70
ADSP-21469	450	N/A	No	No	No	0 to +70
ADSP-21469W	400	N/A	No	Yes	Yes	–40 to +85
