32819X 64k 256k Dynamic RAM ControllerDrivers
General Description
The DP8417841884198419X represent a family of 256k
DRAM ControllerDrivers 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 National’s 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 RowColumn 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 National’s new DP8429D 1 Mbit DRAM Controller
Driver
Each device is available in plastic DIP Ceramic DIP and
Plastic Chip Carrier (PCC) packaging (Continued)

Operational Features
Y
Makes DRAM Interface and refresh tasks appear virtu-
ally transparent to the CPU making DRAMs as easy to
use as static RAMs
Y
Specifically designed to eliminate CPU wait states up to
10 MHz or beyond
Y
Eliminates 15 to 20 SSIMSI components for significant
board real estate reduction system power savings and
the elimination of chip-to-chip AC skewing
Y
On-board ultra precise delay line
Y
On-board high capacitive RAS CAS WE and address
drivers (specified driving 88 DRAMs directly)
Y
AC specified for directly addressing up to 8 Megabytes
Y
Low powerhigh speed bipolar oxide isolated process
Y
Upward pin and function compatible with new DP8428
DP8429 1 Mbit DRAM controller drivers
Y
Downward pin and function compatible with DP8408A
DP8409A 64k256k DRAM controllerdrivers
Y
4 user selectable modes of operation for Access and
Refresh (2 automatic 2 external)
