CascadeTeq QSPI pSRAM CSS6404LS-LJ
CSS6404LS-LJ
CSS6404LS-LJ is a 64 Mbit QSPI pSRAM from CascadeTeq. It runs from a single 3.3 V supply in an SOP-8 150 mil package and is industrial-grade (–40 °C to +85 °C). The device supports 133 MHz 32-byte wrap burst and 84 MHz linear cross-page modes, delivering 84 MB/s bandwidth. On-chip self-refresh eliminates external DRAM controllers; standby is 250 µA, Halfsleep mode only 100 µA, and active current ≤7 mA. It has passed EMI and vibration qualification and can drop-in replace imported ISSI/AP Memory parts. Typical uses include infotainment, industrial control, wearables, and IoT endpoints for data buffering and code expansion.
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.
