CascadeTeq QSPI pSRAM CSS3204LU-L-A2
CSS3204LU-L-A2
CSS3204LU-L-A2 is CascadeTeq’s 32-Mbit QSPI pSRAM (4 Mbit × 8) in a 3.3 V USON-8 package. The QSPI interface enables high-speed data transfer, the ultra-compact USON-8 footprint satisfies integration demands of miniature devices, and the 3.3 V operating voltage aligns with common supply rails. Targeted at applications requiring moderate storage while prioritizing small size and interface simplicity—such as compact IoT devices and smart sensor nodes—it delivers reliable data buffering and rapid access.
Since its founding in 2009 in Hsinchu, Taiwan, CascadeTeq has focused on low-pin-count pSRAM and partnered with PSMC to mass-produce 16–256 Mb devices on a 25 nm DRAM process, certified to ISO 9001 and AEC-Q100. Its SQPI/Octal DDR interface delivers 3.2 Gbps at 200 MHz, on-die self-refresh eliminates external controllers, standby is only 5 µA and active current <5 mA; housed in 2 mm×3 mm USON/QFN, 1.8–3.3 V single supply and –40 °C to +105 °C operation combine high speed, low power and tiny size at competitive cost. Already shipping in smart cameras, industrial gateways, wearables and in-vehicle voice modules, it has become the mainstream cache solution for AIoT and automotive applications, with Mandu Technology providing comprehensive storage solutions and support.
