64/128 Mb NOR flash for automotive, industrial and IoT designs

January 27, 2017 // By Graham Prophet
Cypress presents its latest FL-L NOR flash memories as offering enhanced security, reliability and performance; the 64Mb and 128Mb Quad SPI devices Join 256 Mb density devices in a 3.0V family with, 4 KB uniform sector size, AEC-Q100 qualification and deep power-down mode

The 64 Mb and 128 Mb densities of NOR Flash memories with a Quad Serial Peripheral Interface (Quad SPI) provide 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 suitable for high-performance applications, such as Advanced Driver Assistance Systems (ADAS), automotive instrument clusters and infotainment systems, industrial control and smart factory equipment.

 

Cypress’ 128Mb and 256Mb 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 64Mb devices leverage a 54-MHz DDR mode to deliver read bandwidth of 54 Mbps. The memories provide low standby current and a deep-power-down mode. 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 manufacturing throughput with a 0.30-msec program time per 256 bytes, and they offer a 50-msec erase time. The devices are available in industry-standard packages including the USON (4 x 4 mm) package that saves board space and simplifies layout.

 

Cypress' FL064L 64 Mb Quad SPI NOR Flash memory is qualified and has started production in 24-ball BGA, 8-pin SOIC and 8-contact USON packages. The FL128L 128Mb device is sampling in 24-ball BGA, 8-pin SOIC and 8-contact WSON packages and will go into volume production in the second quarter of 2017.
