1 Megabit High Speed Dynamic Ram Controller/drivers - National Semiconductor

The DP8428 and DP8429 1M DRAM Controller/Drivers are designed to provide No-Waitstate CPU Interface to Dy- namic RAM arrays of up to 8 Mbytes and larger. The DP8428 and DP8429 are tailored for 32-bit and 16-bit sys- tem requirements, respectively. Both devices 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 1M DRAM con- troller functions on a single monolithic device: ultra precise delay line; 9 bit refresh counter; fall-through row, column, and bank select input latches; Row/Column address mux- ing logic; on-board high capacitive-load RAS, CAS, Write Enable and Address output drivers; and, precise control sig- nal Timing for all the above.
