CascadeTeq UHB pSRAM CSH51316SB-A3
CSH51316SB-A3
CSH51316SB-A3 is Kaixin’s 512 Mbit Ultra-High-Bandwidth pseudo-SRAM (UHB pSRAM) organized as 64 Mbit × 8. It supports dual-supply operation at 1.8 V or 1.2 V and is offered in a TBD package. Leveraging ultra-high bandwidth, the device delivers rapid read/write performance to handle large, bursty data streams with ease, while preserving pSRAM’s simple interface and DRAM-like density. The dual-voltage scheme adds flexible power scaling, letting designers choose the optimal rail to balance performance and energy consumption for any target application.
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.
