able parts may utilize the Secured Sector as bo-
nus space, reading and writing like any other Flash
sector, or may permanently lock their own code
there.
The WP#/ACC pin provides two functions. The
Write Protect function provides a hardware method
of protecting the boot sectors without using a high
voltage. The Accelerate function speeds up pro-
gramming operations, and is intended primarily to
allow faster manufacturing throughput.
Two power-saving features are embodied in the
HY29LV320. When addresses have been stable
for a specified amount of time, the device enters
the automatic sleep mode. The host can also place
the device into the standby mode. Power con-
sumption is greatly reduced in both these modes.
Common Flash Memory Interface (CFI)
To make Flash memories interchangeable and to
encourage adoption of new Flash technologies,
major Flash memory suppliers developed a flex-
ible method of identifying Flash memory sizes and
configurations in which all necessary Flash device
parameters are stored directly on the device.
Parameters stored include memory size, byte/word
configuration, sector configuration, necessary volt-
ages and timing information. This allows one set
of software drivers to identify and use a variety of
different, current and future Flash products. The
standard which details the software interface nec-
essary to access the device to identify it and to
determine its characteristics is the Common Flash
Memory Interface (CFI) Specification. The
HY29LV320 is fully compliant with this specification.
