This SDRAM is commonly used in networking, telecommunications, and embedded systems.

Application Scenarios & Design Considerations

4 M SRAM (256-kword x 16-bit)

Alternative Part Number

  • IS61WV25616BLL-10TLI --: 256K x 16 asynchronous SRAM with comparable speed grade and 44-pin TSOP package, widely used as a drop-in replacement for Hitachi SRAMs.
  • CY7C1041CV33-10ZXI --: 256K x 16 low-power SRAM in 44-pin TSOP II, similar access time and pinout, a common alternate source for this memory class.
  • AS6C4008-55TIN --: 512K x 8 low-power CMOS SRAM offering comparable performance and package options, suitable when a different organization is acceptable.
