CascadeTeq OPI pSRAM CSS12808SQ-LJ
CSS12808SQ-LJ
CSS12808SQ-LJ is a 128 Mbit (16 Mbit × 8) Octal SPI (OPI) pSRAM in a QFN-16 package. Operating at 1.8 V and delivering up to 3.2 Gbps peak bandwidth, it is ideal for low-power applications such as smart wearables and edge AI. Key features include a 144 MHz clock and 512-byte page size for 15 ms low-latency access, an industrial temperature range of –40 °C to +85 °C with 50 G vibration tolerance, on-chip ECC ensuring a bit-error rate below 10⁻¹², 1.8 µA standby current, and PASR technology that cuts sleep-mode current to 0.8 µA—significantly extending battery life.
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.
