Application Scenarios & Design Considerations

512K x 8 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM

Alternative Part Number

  • AS6C4008-55TIN --: Alliance Memory is a well-known second source for ISSI SRAMs; this 512Kx8 low-power SRAM matches the 55 ns speed and TSOP package, making it a near drop-in replacement.
  • CY62148EV30LL-55ZSXI --: Cypress MoBL low-power 512Kx8 SRAM with 55 ns access time and similar TSOP-II footprint; widely available and electrically compatible for most designs.
  • IS61WV5128EDBLL-55TLI --: Same manufacturer's newer high-speed 512Kx8 SRAM series with 55 ns speed and compatible pinout, offering a straightforward upgrade path within the ISSI family.
  • AS6C62256-55SIN --: Alliance Memory is a well-known second-source supplier for legacy SRAMs; this 32Kx8 low-power SRAM offers a similar 55ns access time and 5V operation, making it a practical drop-in for many IS62WV5128 designs after pin/package verification.
  • CY62256NLL-55ZXI --: Cypress 32Kx8 low-power SRAM with 55ns speed grade and industrial temperature range; widely available and electrically similar, suitable as a functional alternative when the reduced density is acceptable.
  • AS6C4008-55SIN --: 512Kx8 low-power SRAM from Alliance Memory with 55ns access time, matching the density and speed class of the IS62WV5128BLL; a strong second-source option for 5V legacy designs.
