AS8F512K32

The Austin Semiconductor, Inc. AS8F512K32 is a 16 Megabit CMOS FLASH Memory Module organized as 512Kx32 bits. That 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 of AS8F512K32 are fully automatic. Data-protection of any sector combination is accom-plished using a hardware sector-protection feature.

The Erase/Resume function of AS8F512K32 allows the sector erase operation to read data from, or program to a non-erasing sector, then resume the erase operation.

AS8F512K32 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 AS8F512K32, and outputs data stored in the device. On initial power-up operation, the device defaults to the read mode.
