File Size : 116 KB Manufacturer:△U Description:The DP8417 8418 8419 8419X represent a family of 256k DRAM Controller Drivers which are designed to provide No-Waitstate CPU interface to Dynamic RAM arrays of up to 2 Mbytes and larger Each device offers slight functional variations of the DP8419 design which are tailored for differ- ent system requirements All family members are fabricated using Nationals new oxide isolated Advanced Low power Schottky (ALS) process and use design techniques which enable them to significantly out-perform all other LSI or dis- crete alternatives in speed level of integration and power consumption Each device integrates the following critical 256k DRAM controller functions on a single monolithic device ultra pre- cise delay line 9-bit refresh counter fall-through row col- umn and bank select input latches Row Column address muxing logic on-board high capacitive-load RAS CAS and Write Enable Address output drivers and precise control signal timing for all the above There are four device options of the basic DP8419 Control- ler The DP8417 is pin and function compatible with the DP8419 except that its outputs are TRI-STATEThe DP8418 changes one pin and is specifically designed to offer an optimum interface to 32 bit microprocessors The DP8419X is functionally identical to the DP8419 but is avail- able in a 52-pin DIP package which is upward pin compati- ble with Nationals new DP8429D 1 Mbit DRAM Controller Driver Each device is available in plastic DIP Ceramic DIP and Plastic Chip Carrier (PCC) packaging (Continued)
