PSRAM (Pseudo SRAM) Memory IC 512Mbit HyperBus 166 MHz 36 ns 24-TFBGA (6x8)
The IS66/67WVH64M8DALL/BLL are 512Mb Dual Die device containing two units of 256Mbit Pseudo
Static Random Access Memory, organized as 64M words by 8 bits. The device supports a HyperBus
interface, Very Low Signal Count (Address, Command and data through 8 DQ pins), Hidden Refresh
Operation, and Automotive Temperature Operation, designed especially for Mobile and Automotive
applications
