HyperBus™ products use the high performance HyperBus for connection between a host system master and one or more slave interfaces. HyperBus is used to connect microprocessor, microcontroller, or ASIC devices with random access NOR Flash memory, RAM, or peripheral devices. HyperBus is an interface that draws upon the legacy features of both parallel and serial interface memories, while enhancing system performance, ease of design, and system cost reduction. Parallel flash and PSRAM have long been the standard for simple interface, high performance, random access memory, used for embedded system code execution and data storage. However, parallel interface memory requires a high signal count with separate control, address, and data connections that involve 45 or more signals. There have been parallel interface variations that reduce the signal count by multiplexing some address and data signals yet, may still involve 20 or more signals.
