Quad SPI (QSPI) PSRAM SDR in SOP8 Package

AP Memory Quad SPI (QSPI) PSRAM SDR in SOP8 Package offers Internet of Things (IoT) RAM in 16M to 64M densities with 2Mx8 or 8Mx8 organization. The SOP8 package version supports the most simple PCB design. Depending on the device, they have maximum clock frequencies from 84MHz to 144MHz. AP Memory QSPI Pseudostatic Random Access Memory (PSRAM) SDRs operating supply voltages are available in 1.8V and 3V versions. These devices support industrial grade (-40°C to +85°C) by default as well as extended temperature (-40°C to +105°C).
