CSS12804SQ is a 128 Mbit (16 M × 8) high-performance QSPI pSRAM powered by a single 1.8 V supply and packaged in a 3 mm × 3 mm QFN-16. It supports Quad-SPI clocks above 200 MHz, delivering burst bandwidth up to 84 MB/s. On-chip self-refresh removes the need for an external DRAM controller; standby current drops to the 1 µA range and active power stays ≤7 mA. The device combines SRAM-like speed with DRAM-like density and is certified to both ISO 9001 and AEC-Q100. It is ideal for high-reliability, low-power buffering in wearables, AIoT nodes, automotive electronics and industrial control 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.
