AS8S128K32 is a 4 Megabit CMOS SRAM Module organized as 128Kx32-bits and user configurable to 256Kx16 or 512Kx8. The AS8S128K32 achieves high speed access, low power consumption and high reliability by employing advanced CMOS memory technology. The military temperature grade product is suited for military applications. The AS8S128K32 is offered in a ceramic quad flatpack module per SMD-5962-95595 with a maximum height of 0.140 inches. This module makes use of a low profile, mutlichip module design. This device is also offered in a 1.075 inch square ceramic pin grid array per SMD 5692-93187, which has a maximum height of 0.195 inches. This package is also a low profile, multi-chip module design reducing height requirements to a minimum.
