With 4 kB uniform sector size for efficient code updates, Cypress' FL-L family device provides flexibility for storing program code and parametric data in high-performance embedded systems

The FL-L NOR flash device from Cypress combines the Quad SPI with a 4 kB uniform sector size to deliver highest read bandwidth and fastest program time while enabling a small PCB layout. Using small, uniform physical memory sectors allows the device to optimally store program code and parametric data. The device is suitable for high-performance applications, such as video game consoles, Advanced Driver Assistance Systems (ADAS), automotive instrument clusters and infotainment systems, networking equipment and set-top boxes.

High-performance system designs – Cypress notes – require the highest read bandwidth for program execution, a small low-pin-count package and the fastest program and sector erase times. This flash device uses 66-MHz Double Data Rate (DDR) mode to deliver read bandwidth of 66 MBps and enable the fastest program execution for high-performance systems. The device is available in small 48-mm² packages that save board space and simplify layout. The device provides a 0.30-msec program time per 256 Bytes, increasing manufacturing throughput, and a 50-msec sector erase time, enabling new data to be written quickly. The memories provide low standby current and a deep-power-down mode that extends battery life for battery powered applications. The FL-L NOR Flash family offers AEC-Q100 automotive qualification and supports an extended temperature range of -40°C to +125°C.

The memory is now sampling in 24-ball BGA, 16-pin SOIC and 8-contact WSON packages.
