The hardware RESET# pin terminates any operation in progress and resets the
device, after which it is then ready for a new operation. The RESET# pin may be
tied to the system reset circuitry. A system reset would thus also reset the device,
enabling the host system to read boot-up firmware from the Flash memory
device.
The device reduces power consumption in the standby mode when it detects
specific voltage levels on CE# and RESET#, or when addresses have been stable
for a specified period of time.
The SecSi™ (Secured Silicon) Sector provides a 128-word/256-byte area for
code or data that can be permanently protected. Once this sector is protected,
no further changes within the sector can occur.
The Write Protect (WP#/ACC) feature protects the first or last sector by as-
serting a logic low on the WP# pin.
MirrorBit flash technology combines years of Flash memory manufacturing expe-
rience to produce the highest levels of quality, reliability and cost effectiveness.
The device electrically erases all bits within a sector simultaneously via hot-hole
assisted erase. The data is programmed using hot electron injection.
