CascadeTeq QSPI pSRAM CSS1604LQ
CSS1604LQ
CSS1604LQ is a 16 Mbit (8 M × 8) QSPI pseudo-SRAM introduced by CascadeTeq. Packaged in a 3.3 V QFN-16, it combines a high-speed QSPI interface for efficient data transfer with a compact, thermally and electrically robust footprint—ideal for space-constrained, stability-critical applications such as miniature smart devices and IoT terminal modules.
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.
