FEATURES:
Four 512k SRAM architecture RAD-PAK® technology hardens against natural space radiation technology Total dose hardness: typical krad (Si); dependent upon orbit single event latchup MeV/mg/cm2 threshold MeV/mg/cm2 Package: 68-pin quad flat package Fast access time: 25,30 Completely static memory clock timing strobe required Internal bypass capacitor High-speed silicon-gate CMOS technology power supply Equal address chip enable access times Three-state outputs inputs outputs compatible
DESCRIPTION:
Space Electronics' 89C1632RP RAD-PAK®) high-performance Megabit Multi-Chip Module (MCM) Static Random Access Memory features typical kilorad (Si) total dose tolerance. four 4-Megabyte SRAM bypass capacitors incorporated into high-reliable hermetic quad flat-pack ceramic package. With high-performance silicongate CMOS technology, 89C1632RP reduces power consumption eliminates need external clocks timing strobes. equipped with output enable (OE) four byte enable (CS1 CS4) inputs allow greater system flexibility. When input high, output forced high impedance. 89C1632RP been specifically designed meet exposure radiation environments. total-dose survivability greater than krad (Si), based GEO-type orbit (actual tolerance depends upon orbit mission duration). Space Electronics' RADPAK® advanced technology incorporates radiation shielding microcircuit package that eliminates shielding. 89C1632RP available Class Class packaging screening.

FIGURE TIMING WAVEFORM WRITE CYCLE CONTROLLED)
write cycle timing referenced from last valid address first transition address. write occurs during overlap write begins latest transition going going low. write ends earliest transition going high going high. measured from beginning write write. measured from later going write. measured from address valid beginning write. measured from write address change. applied case write ends going high. Read Mode during this period, pins output low-Z state. Inputs opposite phase output must applied because contention occur. common applications, minimization elimination contention conditions necessary during read write cycle. foes simultaneously with going after going low, outputs remain high impedance state. DOUT read data address. When low, pins output state. input signals opposite phase leading output should applied.
