GENERAL DESCRIPTION

The Austin Semiconductor, Inc. AS8F512K32 is a 16 Megabit

CMOS FLASH Memory Module organized as 512Kx32 bits. The

AS8F512K32 achieves high speed access (70 to 150 ns), low power

consumption and high reliability by employing advanced CMOS memory

technology.

An on-chip state machine controls the program and erase func-

tions. The embedded byte-program and sector/chip erase functions are

fully automatic. Data-protection of any sector combination is accom-

plished using a hardware sector-protection feature.

The Erase/Resume function allows the sector erase operation to

read data from, or program to a non-erasing sector, then resume the

erase operation.

Device operations are selected by using standard commands into

the command register using standard microprocessor write timings. The

command register acts as an input to an internal state machine that

interprets the commands, controls the erase and programming opera-

tions, outputs the status of the device, and outputs data stored in the

device. On initial power-up operation, the device defaults to the read

mode.
