Asahi Kasei Microdevices AK7018 Multi-Core DSPs/SRCs

Asahi Kasei Microdevices AK7018 Multi-Core Digital Signal Processors (DSPs) / Sampling Rate Converters (SRCs) is a highly integrated device in a 100-pin HLQFP. The device includes eight stereo and four monaural sampling rate converters supporting sampling frequencies up to 192kHz, a DIR, a DIT, and DSPs for audio and voice processing. The DSP1 and DSP2 support a 491.52MHz operation clock and are optimized for C-language support. The automotive-grade Asahi Kasei Microdevices AK7018 can process multiple sample rates simultaneously. The RAM-based AK7018 can be freely programmed to meet user requirements.
