HB56A132 Datasheet | Hitachi Semiconductor

Description The HB56A132 is a 1 M × 32 dynamic RAM module, mounted 8 pieces of (4-Mbit) DRAM (HM514400CS/CLS) sealed in SOJ package. An outline of the HB56A132 is 72-pin single in-line package. Therefore, the HB56A132 makes high density mounting possible without surface mount technology. The HB56A132 provides mon data inputs and outputs. Decoupling capacitors are mounted beneath each SOJ. Features - 72-pin single in-line package - Lead pitch: 1.27 mm - Single 5 V (± 5%) supply - High speed - Access time: 60 ns/70 ns/80 ns (max) - Low power dissipation - Active mode: 4.62W/4.20W/3.78W (max) - Standby mode: 84 m W (max) 4.2 m W (max) (L-version) - Fast page mode capability - 1,024 refresh cycle: 16 ms 128 ms (L-version) - 2 variations of refresh - RAS only refresh - CAS before RAS refresh - TTL patible HB56A132 Series Ordering Information Type No. HB56A132BW-6C HB56A132BW-7C HB56A132BW-8C HB56A132BW-6CL HB56A132BW-7CL HB56A132BW-8CL HB56A132BU-6C HB56A132BU-7C HB56A132BU-8C HB56A132BU-6CL HB56A132BU-7CL HB56A132BU-8CL HB56A132SBW-6C HB56A132SBW-7C HB56A132SBW-8C HB56A132SBW-6CL HB56A132SBW-7CL HB56A132SBW-8CL Access time 60 ns 70 ns 80 ns 60 ns 70 ns 80 ns 60 ns 70 ns 80 ns 60 ns 70 ns 80 ns 60 ns 70 ns 80 ns 60 ns 70 ns 80 ns Package 72-pin SIP socket type Contact pad gold 72-pin SIP socket type solder Pin...
