CascadeTeq OPI pSRAM CSS12808LB-LJ
CSS12808LB-LJ
CSS12808LB-LJ is a 128 Mbit (16 M × 8) Octal-SPI (OPI) pSRAM in a 3.3 V BGA-24 package, delivering peak bandwidth up to 3.2 Gbps for high-bandwidth applications such as smart cameras and AR/VR devices. Key advantages include a 144 MHz clock with 512-byte page size, enabling 15 ms low-latency data handling; an industrial temperature range of –40 °C to +105 °C and 50 g vibration tolerance; on-die ECC that keeps bit-error rates below 10⁻¹²; 1.8 µA standby current, and PASR technology that cuts sleep current to 0.8 µA to markedly extend battery life. The 3 mm × 3 mm ultra-thin package supports high-density integration and is qualified for harsh environments including automotive ADAS and edge-AI systems.
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.
