CSS12804SS-O

CSS12804SS-O is a 128 Mbit QSPI pSRAM from CascadeTeq, organized as 16 M × 8 bits. It operates from a single 1.8 V supply in a 150 mil SOP-8 package and is qualified for the industrial temperature range of –40 °C to +85 °C. The device supports a 133 MHz four-wire SPI clock and delivers burst-read bandwidth up to 84 MB/s. With on-chip self-refresh logic, no external DRAM controller is required; standby current is about 250 µA, Half-sleep mode drops to 100 µA, and active power remains ≤7 mA. Having passed both EMI and vibration tests, it is a drop-in replacement for imported parts such as ISSI or AP Memory pSRAM. It is ideal for low-power, high-reliability buffering in automotive infotainment, industrial gateways, AIoT terminals, and wearable devices.

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.
