Application Scenarios & Design Considerations

262,144-WORD BY 16-BIT CMOS STATIC RAM

Alternative Part Number

  • IS61LV25616AL-15TLI --: 256K x 16 asynchronous SRAM with 15 ns access time, pin-compatible 44-pin TSOP package, widely available and a common drop-in replacement for 256K x 16 SRAMs.
  • CY7C1041CV33-15ZXI --: 256K x 16 low-power SRAM with 15 ns speed grade and 3.3 V supply, functionally equivalent and available in a compatible TSOP-II package.
  • AS7C256A-15TCN --: 256K x 16 asynchronous SRAM, 15 ns access time, 3.3 V operation, designed as a legacy SRAM replacement with matching pinout and timing.
  • CY7C1041CV33-15ZXC --: 256K x 16 low-power SRAM, 15 ns speed grade, 3.3 V operation, widely available and functionally equivalent to the Toshiba part.
  • AS6C25616-55TIN --: 256K x 16 CMOS SRAM in 44-pin TSOP, 3.3 V compatible, drop-in alternative when a slightly slower access time is acceptable.
