The IS62WV51216BLL-55TLI-TR is an 8M-bit SRAM chip from ISSI. It includes an asynchronous single 3.3V 512K x 16 bits memory organization and is designed in a 44-Pin TSOP-II (Thin Small Outline Package-II) form factor. This chip operates at a speed of 55 nanoseconds and the T/R (Top/Bottom) designation for the device indicates that the package has both the top and bottom contacts exposed. It is also equipped with a VDDQ power supply option to support a wide range of system operating and input voltage levels.This SRAM chip is ideal for applications that require a large, fast, and low-power SRAM with an easy TSOP-II package. Additionally, its features make it ideal for a range of uses including general memory designs, communications systems, buffer memory, network systems, consumer electronics, and automotive applications.
