Quad SPI (QSPI) PSRAM SDRs in USON8 Package

AP Memory Quad SPI (QSPI) PSRAM SDRs in a USON8 Package delivers Internet of Things (IoT) RAM ranging from 16M to 64M densities with 2M x8 or 8M x8 organization. The PSRAM SDRs are offered in the USON8 package resulting in a compact solution compared to SOP8 but keeping the simplicity of PCB. The Quad SPI Pseudo Static Random Access Memory (PSRAM) SDRs feature a maximum clock frequency from 84MHz to 144MHz, depending on the device. Additionally, the devices support operating supply voltages in 1.8V and 3V versions, with an -40°C to 85°C industrial grade temperature range. AP Memory Quad SPI PSRAM SDRs in a USON8 package are ideal in memory selection for SoC applications requiring low pin count and ultra-low power extended memory.
