The four 4-Megabit SRAM die and bypass capacitors are incorporated into a high-reliable hermetic quad flat-pack ceramic package. With high-performance silicon-gate CMOS technology, the 89C1632 reduces power consumption and eliminates the need for external clocks or timing strobes. It is equipped with output enable (OE) and four byte enable (CS1 - CS4) inputs to allow greater system flexibility. When OE input is high, the output is forced to high impedance. Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. In a GEO orbit, RAD-PAK provides true greater than 100 krad (Si) total radiation dose tolerance, dependent upon space mission. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or a space mission.

At any given temperature and voltage conditions, tHZ (max) is less than tLZ (min) both for a given device and from device to device. 5. Transition is measured +200mV from steady state voltage with Load(B). This parameter is sampled and not 100% tested. 6. Device is continuously selected with CS = VIL. 7. Address valid prior to coincident with CS transition low. 8. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and write cycle. FIGURE 4.

All write cycle timing is referenced from the last valid address to the first transition address. 2. A write occurs during the overlap of a low CS and WE. A write begins at the latest transition CS going low and WE going low. A write ends at the earliest transition CS going high or WE going high. tWP is measured from the beginning of write to the end of write. 3. tCW is measured from the later of CS going low to end of write. 4. tAS is measured from the address valid to the beginning of write. 5. tWR is measured from the end of write to the address change. tWR applied in case a write ends as CS or WE going high. 6. If OE, CS and WE are in the Read Mode during this period, the I/O pins are in the output low-Z state. Inputs of opposite phase of the output must not be applied because bus contention can occur. 7. For common I/O applications, minimization of elimination of bus contention conditions is necessary during read and write cycle. 8. If CS foes low simultaneously with WE going or after WE going low, the outputs remain high impedance state. 9. DOUT is the read data of the new address. 10.When CS is low, I/O pins are in the output state. The input signals in the opposite phase leading to the output should not be applied.
