Application Scenarios & Design Considerations

64M(4Mx16) DDR SDRAM

Alternative Part Number

  • MT48LC4M16A2P-7E --: 64Mb SDR SDRAM organized as 4M x 16, same 54-pin TSOP package and 3.3V interface; 7ns speed grade is faster than the 3.6ns/36-pin original, so timing is compatible with margin.
  • IS42S16400J-7TL --: 64Mb SDR SDRAM in 4M x 16 organization with 3.3V supply and TSOP-II package; widely used drop-in replacement for HY5DV641622 series with comparable or better speed.
  • W9864G6JH-6 --: 64Mb SDR SDRAM, 4M x 16 configuration, 3.3V, TSOP-54; 6ns speed grade meets or exceeds the original -36 timing and is a common second-source option.
