HM5116405 Series

      The HM5116405 Series has the following features including Single 5 V ( 10%);Access time: 50 ns/60 ns/70 ns (max);Power dissipationActive mode : 495 mW/440 mW/385 mW (max) (HM5116405 Series),: 550 mW/495 mW/440 mW (max) (HM5117405 Series),Standby mode : 11 mW (max): 0.83 mW (max) (L-version);EDO page mode capability;Long refresh period 4096 refresh cycles : 64 ms (HM5116405 Series),: 128 ms (L-version),2048 refresh cycles : 32 ms (HM5117405 Series): 128 ms (L-version);3 variations of refresh etc.
      The Hitachi  HM5116405 Series are CMOS dynamic RAMs organized 4,194,304-word 4-bit. They employ the most advanced CMOS technology for high performance and low power. The HM5116405 Series offer Extended Data Out (EDO) Page Mode as a high speed access mode. They have package variations of standard 26-pin plastic SOJ and standard 26-pin plastic TSOP II. In a test mode read cycle, the value of tRAC, tAA, tCAC and tCPA is delayed by 2 ns to 5 ns for the specified value. These parameters should be specified in test mode cycles by adding the above value to the specified value in this data sheet.tHPC (min) can be achieved during a series of EDO page mode write cycles or EDO page mode read cycles. If both write and read operation are mixed in a EDO page mode cycle (EDO page mode mix cycle (1), (2)), minimum value of cycle (tCAS + tCP + 2 tT) becomes greater than the specified tHPC (min) value. The value of cycle time of mixed EDO page mode is shown in EDO page mode mix cycle (1) and (2).
