Description Please notice the marks on the chip are removed, but all functions remain the same, if you mind this please don’t buy. The PSRAM64H is a 64 Mbit (8 Megabyte) serial pseudo SRAM device, organized in 8 M x 8 bits and in a compact SOIC-8 package. It is fabricated using the high-performance and high-reliability CMOS technology and can operates at 3.3V and can support up to 133 MHz clock rate. Note, however, that burst operations which cross page boundaries have a lower max input clock frequency at 84 MHz. The PSRAM device can be accessed via basic Serial Peripheral Interface (SPI) or faster Quad Peripheral Interface (QPI) is supported if the application needs faster data rates. Because it is RAM not FLASH or EEPROM, this device supports unlimited reads and writes to the memory array. Price for two units. Clock Frequency:133MHz Memory Format:PSRAM Memory Interface:SPI Memory Size:64Mb (8M x 8) Memory Type:Volatile Mounting Type:Surface Mount Operating Temperature:-40°C ~ 85°C Package / Case:8-SOIC (0.154″, 3.90mm Width) Supplier Device Package:8-SOIC Technology:PSRAM (Pseudo SRAM) Voltage – Supply:2.7V ~ 3.6V
