HyperRam™ & Octal xSPI RAM

HyperRam™ & Octal xSPI RAM | サイプレスセミコンダクタ

HyperRAM™ is a high-speed, low-pin-count, low-power self-refresh Dynamic RAM (DRAM) for high-performance embedded systems requiring expansion memory. HyperRAM™ offers JEDEC compliant HyperBus™ and Octal SPI interfaces that draw upon the legacy features of both parallel and serial interface memories, while enhancing system performance and ease of design, as well as reducing system cost. HyperRAM the ideal scratchpad/buffering off-chip memory for controllers with limited on-board RAM such as automotive instrument clusters, industrial HMI, industrial machine vision and display systems for consumer electronics.

HyperBus utilizes a high-speed 8-bit DDR interface for both address and data. In addition, it uses a differential clock, a read/write latch signal, and a chip select for each memory device. HyperBus supports external flash and RAM on the same bus, and works with any microcontroller with a HyperBus compatible peripheral interface.

For more details on how the HyperRAM™ provides a low-pin expansion memory solution, read this whitepaper.
