CascadeTeq QSPI pSRAM CSS1604SU-M
CSS1604SU-M
CSS1604SU-M is CascadeTeq’s 16 Mbit (8 M × 8) QSPI pseudo-SRAM in a 1.8 V USON-8 package. Its 4-line QSPI interface delivers high-speed data transfers, while the ultra-small USON-8 outline fits the tightest spaces, and the 1.8 V supply minimizes power draw. These traits make it ideal for small-footprint, energy-sensitive applications—think smart wearables and ultra-low-power IoT sensors—providing rock-solid buffering and access to modest data sets.
CascadeTeq pSRAM is a pseudo-static RAM family purpose-built for “high-speed cache + tiny footprint + ultra-low power” scenarios. Fabricated on a 25 nm DRAM process, it replaces the traditional DRAM controller with on-die self-refresh and presents a simple SPI/QSPI/Octal-DDR interface, allowing an MCU to achieve burst bandwidths of 480 Mbps to 3.2 Gbps over only 4–8 pins. Densities span 16 Mb to 256 Mb, packages shrink to 2 mm × 3 mm USON-8, and the devices operate from –40 °C to +105 °C with full AEC-Q100 qualification for automotive or harsh outdoor applications. In mainland China, CascadeTeq is professionally represented by Shenzhen Mandu Technology, which provides device selection guidance, technical support, and rapid sample service to shorten customer development cycles.
