64k, 256k Dynamic Ram Controller/drivers - National Semiconductor

The DP84300 DP84412 DP84512 DP84322 DP84422 DP84522 DP84432 DP84532 DP8400-2 DP8400-4 DP8402A 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-STATE. The 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.
