Application Scenarios & Design Considerations

4 Banks x 2M x 16bits Synchronous DRAM

Alternative Part Number

  • IS42S16800F-7TL --: 16Mbit SDR SDRAM organized as 2M x 8 x 4 banks, same 54-pin TSOP II package and 3.3V interface, widely available drop-in replacement for HY57V281620AT-K.
  • MT48LC16M16A2P-7E --: 16Mbit SDR SDRAM in 2M x 8 x 4 bank configuration with compatible 3.3V timing and 54-pin TSOP package, a well-established alternative from a major DRAM vendor.
  • W9825G6JH-6 --: 16Mbit SDR SDRAM with 4 banks x 2M x 8 organization, 3.3V operation and TSOP II footprint, offering similar speed grades and reliable second-source availability.
