## Description

The IS66WVS16M8FBLL-104NLI is an integrated PSRAM memory IC with 128 Mbits of pseudo static RAM, organised as 16 Megabytes words by 8 bits. It uses a self-refresh DRAM array and is built as a dual die stack of two 64Mb die.This device supports both SPI (Serial Peripheral Interface) and QPI (Quad Peripheral Interface), giving it a low signal-count connection for embedded designs. It uses just six signal pins: CLK, CE#, and four SIOs.Hidden refresh operation is supported, and the part is specified for industrial temperature and Automotive A2-grade temperature use. In-band reset is supported instead of a dedicated RESET# pin, and the minimum transferred data size is 8 bits.Features:PSRAM memory: 128 Mbits of Pseudo Static Random Access MemoryDual die stack: Two 64Mb dieProtocol support: SPI (Serial Peripheral Interface)Protocol support: QPI (Quad Peripheral Interface)Low signal count: 6 signal pins: CLK, CE#, and 4 SIOsRefresh: Hidden Refresh OperationTemperature grade: Industrial temperature and Automotive A2-grade temperatureReset: In-Band Reset is supported instead of a dedicated RESET# pinTransfer size: Minimum transferred data size is 8 bitsSpecifications:Memory Size: 128 MbitMemory Type: PSRAMOrganization: 16 M x 8Access Time: 7nsMaximum Clock Frequency: 104MHzInterface Type: SPISupply Voltage - Max: 3.6VSupply Voltage - Min: 2.7VSupply Current - Max: 300uAMinimum Operating Temperature: -40°CMaximum Operating Temperature: +85°CMounting: SMD/SMTPackage: SOIC-8Moisture Sensitive: YesMFG #: IS66WVS16M8FBLL-104NLIA handy memory IC for custom embedded hardware that needs external PSRAM over an SPI-style interface.
