Infineon S27KS0643GABHV020, DDR SDRAM Memory 64Mbit Surface Mount, 200MHz, 1.7 V to 2 V, 24-Pin FBGA / 2017970

The Cypress Semiconductor S27KL0642/S27KS0642 is a 64 Mb HyperRAM which is a high-speed CMOS, self-refresh DRAM, with Hyper Bus interface. The array of the DRAM uses dynamic cells that require periodic refresh. The refresh control logic which is within the device, manages the refresh operations on the DRAM array when the memory is not being actively read or written by the Hyper Bus interface master (host). The DRAM array appears to the host as though the memory uses static cells that retain data without refresh, as the host is not required to manage any refresh operations. Hence, this memory is more accurately called or can be described as Pseudo Static RAM (PSRAM).Temperature Range: -40°C to +85°C Interface Bandwidth (MBps): 400MBps RoHS Compliant
