Cypress Enhance Security for IoT Applications with New FL-L NOR Flash Memories
Cypress Semiconductor has introduced 64 Mb and 128 Mb densities to its family of NOR Flash memories with a Quad Serial Peripheral Interface (Quad SPI). The new FL-L NOR Flash devices provide the utmost reliability and security for high-performance embedded systems that store critical data and operate at extended temperatures. The FL-L devices also offer low power consumption and AEC-Q100 automotive-grade qualification with high read bandwidth and fast program time at an extended temperature range. Using small, uniform 4 KB physical memory sectors allows the devices to optimally store program code and parametric data. The devices are ideal for high-performance applications, such as Advanced Driver Assistance Systems (ADAS), automotive instrument clusters and infotainment systems, industrial control and smart factory equipment, networking equipment, IoT applications, video game consoles and set-top boxes.
"Our FL-L Quad SPI NOR Flash family offers the highest reliability and enhanced security, along with the bandwidth and small form factor that high-performance applications require," said Rainer Hoehler, Vice President of the Flash Business Unit at Cypress. "Expanding this family fits in with our strategy to offer high-performance memories that combine with Cypress' MCU, analog and connectivity solutions to offer complete embedded system-level solutions for our fast-growing target markets."
High-performance system designs require high read bandwidth for program execution, small, low-pin-count packages, and fast program and erase times. Cypress' 128 Mb and 256 Mb FL-L Quad SPI NOR Flash devices are each capable of 133-MHz Single Data Rate (SDR) and 66-MHz Double Data Rate (DDR) for bandwidth of 67 Mbps, and the 64 Mb devices leverage a 54-MHz DDR mode to deliver read bandwidth of 54 Mbps, enabling fast program execution for high-performance systems. The memories provide low standby current and a deep-power-down mode that extends battery life for battery powered applications. The family offers AEC-Q100 automotive qualification and supports an extended temperature range of -40°C to +125°C. The 128 Mb and 256 Mb devices can increase customers' manufacturing throughput with a fast 0.30-ms program time per 256 bytes, and they offer a 50-ms erase time that enables new data to be written quickly. The devices are available in industry-standard packages including the USON (4mm x 4mm) package that saves board space and simplifies layout.
