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.
