1.
Overview
The HYPERBUSI module provides function and operation for interfacing to the HyperBus memory
devices. The HyperBus achieves both high speed read/write throughput by double data rate interface and
low pin counts. The HYPERBUSI module's features are described in this section.
Features of the HyperBus Interface

Supports operational frequency up to 166MHz

Achieves maximum 333MB/s data throughput by 8 bits bus and few timing signals only

Supports the double data rate interface

Supports two slave devices

Supports XiP operation by dynamic wrapped burst request
