GENERAL DESCRIPTION
The AS8SLC512K32 is a 3.3V 16 Megabit CMOS SRAM
Module organized as 512Kx32 bits. The AS8SLC512K32 achieves
very high speed access, low powerconsumption and high reliability
by employing advanced CMOS memory technology.
This military temperature grade product is ideally suited for
commercial, industrial, and military applications when asynchronous
high speed switching and low ACTIVE opening power & ultra Fast
Asynchronous Access is mandated.

4. This parameter guaranteed but not tested.
5. Test conditions as specified with output loading as
shown in Fig. 1 & 2 unless otherwise noted.
6. tHZCS, tHZOE and tHZWE are specified with CL= 5pF as in
Fig. 2. Transition is measured +/- 200 mV typical from
steady state voltage, allowing for actual tester RC time
constant.

7. At any given temperature and voltage condition,
tHZCS, is less than tLZCS, and tHZWE is less than tLZWE.
8. WE\ is HIGH for READ cycle.
9. Device is continuously selected. Chip selects and output
enable are held in their active state.
10. Address valid prior to or coincident with latest
oc-
curring chip enable.
11. tRC= READ cycle time.
12. Chip enable (CS\) and write enable (WE\) can initiate
and terminate a WRITE cycle.
13. ICC is for full 32 bit mode.
