Cypress Semiconductor Corp. has announced the 3V S26KL256S HyperFlash device as the latest member of its NOR HyperFlash product line. The company claims the 256Mb device is part of the industry's first flash memory family that supports the high-bandwidth, low-pin-count HyperBus interface.

The device is geared for high-performance applications, such as automotive instrument clusters, industrial automation, communication systems and medical equipment, which need the highest read bandwidth to enable the fastest boot time for instant-on requirements, along with a low-pin-count interface to reduce package size and PCB cost.


Running up to 166MHz, HyperFlash products can achieve DDR read bandwidths as high as 333MB/s for 1.8V products and 200MB/s for 3V products. The HyperFlash device is offered in a 48mm2 24-ball package, and it delivers reliable operation over the extended temperature range of -40C to 125C. Cypress' HyperFlash memory family offers 3V and 1.8V versions and includes three densities: 128Mb, 256Mb and 512Mb.

The company said the devices provide a seamless migration path from Quad SPI to dual Quad SPI to HyperFlash memory, allowing system applications to be scaled to different levels of flash performance when paired with compatible controllers. This provides OEMs the ability to offer different product models with a single design.

The 12-pin Cypress HyperBus interface consists of an 8-pin address/data bus, a differential clock (two signals), a chip select and a read data strobe for the controller, all of which help reduce the overall cost of the system through reduced pin count. Memories based on the interface enable systems with faster response times.

Cypress' 3V, 256Mb S26KL256S HyperFlash is sampling with production expected in 3Q15 packaged in a market-compatible 6mm x 8mm BGA.

Cypress also has 128Mb versions of the 1.8V and 3V HyperFlash devices in development, while 1Gb versions of both voltage versions are at the concept stage (see profuct roadmap below).
