GENERAL DESCRIPTION
The AS8FLC1M32B is a 32Mb FLASH Multi
Chip Module organized as 1M x 32 bits. The
module achieves high speed access, low power consumption
and high reliability by employing advanced CMOS memory
technology. The military grade product is manufactured in
compliance to the MIL-PRF-38534 specifications, making the
AS8FLC1M32B ideally suited for military or space applica-
tions. The module is offered in a 68-lead 0.990 inch square
ceramic quad flat pack or 66-lead 1.185inch square ceramic
Hex In-line Package (HIP). The CQFP package design is tar-
geted for those applications, which require low profile SMT
Packaging.
