HyperBusメモリ

Cypress HyperBus Memory is a portfolio of high-speed, low-pin-count memory products that uses our HyperBus interface technology. The HyperBus interface draws upon the legacy features of both parallel and serial interface memories, while enhancing system performance, ease of design, and system cost reduction. The 12-pin, HyperBus interface operates at Double Data Rate (DDR) and can scale up to 333 MB/s throughput making it an ideal solution for automotive, industrial and IoT applications that require “instant-on” capability.

HyperFlash™ NOR Memory Flash devices are the first family of products based on the Cypress HyperBus™ interface. HyperFlash NOR Flash memories deliver the performance required for the highest-performance embedded systems found in automotive advanced driver assistance systems (ADAS), automotive instrument cluster, automotive infotainment systems, and communication equipment.They deliver high read bandwidth at 333MB/s, over four times faster than Quad SPI NOR flash with one-third the number of pins of parallel NOR flash.

​Cypress HyperRAM™ memory is a self-refresh DRAM operating on the 12-pin HyperBus interface.With a read throughput up to 333 MB/s, the HyperRAM devices are ideal for SoCs with limited on-board RAM providing external scratch-pad memory for fast read and write operations, allowing fast delivery of high-resolution graphics in the early part of the boot process for automotive, industrial and IoT applications.

Implementing HyperFlash and HyperRAM together provides an optimum high-performance memory subsystem with 70% fewer pins and a 77% smaller footprint compared to existing SDRAM and Quad SPI solutions.

Cypress HyperFlash™ NOR Memory Flash devices are the first family of products based on the new Cypress HyperBus™ interface.This family features read throughput of up to 333MB/s, more than five times faster than ordinary Quad SPI flash.The Cypress HyperBus technology also allows for connection using one-third the number of pins of parallel NOR flash.

Automotive Cluster Systems

Automotive clusters provide drivers a centralized and easily viewable location for displaying all critical automobile information.

Thin-film transistor (TFT) LCD panels and Heads-up displays have become the dominant choice for displaying high performance graphics that provide real time information to the driver inside his immediate field of view for added safety.

Cypress HyperFlash™ solutions enable automotive clusters with high read bandwidth for program execution to ensure the system can bootup quickly.A wide range of density combinations provide extra scalability and the low-pin-count interface helps reduce design costs.

Cypress’s HyperFlash™ solutions are AEC-Q100 Grade 1 to 3 qualified to meet automotive standards for a wide operating temperature range.

Automotive Cluster System Design Challenges The Cypress Flash Solution
Instant-on with fast graphics performance using TFT LCD 333 MBps read speed at 1.8 V (200 MBps at 3.0V)
Cost control by reducing traces, package and PCB sizes HyperFlash™ and HyperRAM™ share the same 12 bus pins
Single design to support different code sizes and features Flexible Flash and RAM density combination for scalability
Stable power supply over a large fluctuation of battery voltage Independent PG and ENB to ensure a clean supply voltage
Low electromagnetic interference Built-in Spread Spectrum Clock Generator to reduce noise
