HM514400CL Datasheet | Hitachi Semiconductor

ADE-203-269A (Z) 1,048,576-word × 4-bit Dynamic Random Access Memory Rev. 1.0 Nov. 29, 1994 The Hitachi HM514400B/BL, HM514400C/CL are CMOS dynamic RAM organized 1,048,576word × 4-bit. HM514400B/BL, HM514400C/CL have realized higher density, higher performance and various functions by employing 0.8 µm CMOS process technology and some new CMOS circuit design technologies. The HM514400B/BL, HM514400C/CL offer Fast Page Mode as a high speed access mode. Multiplexed address input permits the HM514400B/BL, HM514400C/CL to be packaged in standard 300-mil 26-pin plastic SOJ, standard 400-mil 20-pin plastic ZIP and 26pin plastic TSOP II. - Test function - Battery back up operation - HM514400BL Series (L-version) - HM514400CL Series (L-version) HM514400B/BL Series HM514400C/CL Series Features - Single 5 V (±10%) - High speed - Access time 60 ns/70 ns/80 ns (max) - Low power dissipation - Active mode 605 m W/550 m W/495 m W (max) - Standby mode 11 m W (max) 0.55 m W (max) (L-version) - Fast page mode capability - 1024 refresh cycles : 16 ms 1024 refresh cycles : 128 ms (L-version) - 3 variations of refresh - RAS-only refresh - CAS-before-RAS refresh - Hidden refresh HM514400B/BL, HM514400C/CL Series Ordering Information Type No. HM514400BS-6 HM514400BS-7 HM514400BS-8 HM514400BLS-6 HM514400BLS-7 HM514400BLS-8 HM514400CS-6 HM514400CS-7 HM514400CS-8 HM514400CLS-6 HM514400CLS-7 HM514400CLS-8 HM514400BZ-6 HM514400BZ-7 HM514400BZ-8 HM514400BLZ-6 HM514400BLZ-7 HM514400BLZ-8 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 400-mil 20-pin plastic ZIP (ZP-20) Package 300-mil 26-pin plastic SOJ (CP-26/20D) Type No. HM514400CZ-6 HM514400CZ-7 HM514400CZ-8 HM514400CLZ-6 HM514400CLZ-7 HM514400CLZ-8 HM514400BTT-6 HM514400BTT-7 HM514400BTT-8 HM514400BLTT-6 HM514400BLTT-7 HM514400BLTT-8 HM514400CTT-6 HM514400CTT-7 HM514400CTT-8 HM514400CLTT-6 HM514400CLTT-7 HM514400CLTT-8 Access time 60 ns 70 ns 80 ns 60 ns 70 ns 80 ns 60...
