CSS6404LS-L

CSS6404LU-L is Cascadeteq’s 64 M-bit QSPI pSRAM organized as 8 M × 8 bit. It runs from a single 3.3 V supply and comes in a tiny USON-8 (2 mm × 3 mm) package. Operating at 133 MHz SDR burst mode, it delivers up to 84 MB/s continuous read bandwidth. On-chip self-refresh logic eliminates the need for an external DRAM controller, while standby current is only ~1 µA, merging SRAM-like instant response with DRAM-level density. Industrial-qualified from –40 °C to +85 °C and featuring EMI-hardened design to suppress high-frequency noise, the device is ideal for low-power, space-constrained, high-reliability buffering in wearables, IoT gateways, industrial data loggers, and in-vehicle infotainment systems.

CascadeTeq Inc., headquartered in Hsinchu, Taiwan, maintains R&D and sales offices in both the United States and Mainland China. The company is a fabless semiconductor firm specializing in the research, design, manufacturing, and sales of standard and customized memory and IC solutions, and is currently the global leader in low-pin-count standard pSRAM (LPC pSRAM) design. Its engineering team brings together veteran experts from the United States, Japan, Taiwan, and China to deliver rapid response, professional resources, and flexible services that accelerate customers’ time-to-market. Representative products include the 16 Mbit CSS1604LQ pSRAM, which features high-speed read/write performance, wide-temperature operation (–40 °C to +85 °C), and low power consumption. These devices are widely used in AIoT end products such as smart home devices, industrial IoT systems, and intelligent security cameras, providing real-time data buffering and ensuring smooth system operation. In Mainland China, CascadeTeq is professionally represented by Shenzhen Mandu Technology Co., Ltd., which offers selection consultation, technical support, and sample services to help customers shorten development cycles.
