ADSP-21065L

Product Summary

The ADSP-21065L is a 32-bit processor optimized for cost sensitive applications. It offers the highest levels of performance and memory integration of any 32-bit DSP in the industry. It is also the only DSP in the industry that offer both fixed and floating-point capabilities, without compromising precision or performance. The ADSP-21065L is fabricated in a high speed, low power CMOS process, 0.35 mm technology. With its on-chip instruction cache, the ADSP-21065L can execute every instruction in a single cycle. It combines a floating-point DSP core with integrated, on-chip system features, including a 544 Kbit SRAM memory, host processor interface, DMA controller, SDRAM controller, and enhanced serial ports.
