CSS6408SO-LI

CSS6408SO-LI is a 64 Mbit (8 M×8) OPI pSRAM from CascadeTeq. Operating from a single 1.8 V supply, it is housed in a 3 mm × 3 mm QFN-16 package and rated for the industrial temperature range of –40 °C to +85 °C. The device supports a 200 MHz Octal-SPI bus and delivers burst-read bandwidth up to 400 MB/s. Integrated self-refresh logic eliminates the need for an external DRAM controller; standby current is typically 250 µA, while active power remains ≤7 mA. Its combination of ultra-small footprint, high speed, and low power makes the CSS6408SO-LI ideal for high-density buffer applications in automotive cockpits, AIoT gateways, industrial control systems, and wearables, and it can serve as a drop-in replacement for equivalent devices from ISSI, AP Memory, and other suppliers.

CascadeTeq, headquartered in Hsinchu, Taiwan, is a semiconductor company focused on LPC pSRAM and is strategically partnered with PSMC. The company is certified to ISO 9001 and AEC-Q100. Its SPI/QSPI/Octal-DDR portfolio spans 16–256 Mb and delivers up to 3.2 Gbps at 200 MHz over a minimal 4- to 8-pin interface. On-die self-refresh eliminates external DRAM controllers, while power consumption is only 5 µA standby and <5 mA active; packages start at 2 mm × 3 mm USON/QFN. Key part numbers CSS1604, 6404, and 12808 are already in mass production for smart cameras, industrial gateways, wearables, e-bike dashboards, and in-vehicle voice modules. In mainland China, CascadeTeq is professionally represented by Shenzhen Mandu Technology, which provides selection consultation, technical support, and sample services to shorten customers’ development cycles.
