and more. Using DMS, user-written software does not need to interface with the
Flash memory directly. Instead, the user's software accesses the Flash memory
by calling one of only six functions.
The device offers complete compatibility with the JEDEC 42.4 sin-
gle-power-supply Flash command set standard. Commands are written to
the command register using standard microprocessor write timings. Reading data
out of the device is similar to reading from other Flash or EPROM devices.
The host system can detect whether a program or erase operation is complete by
using the device status bits: RY/BY# pin, DQ7 (Data# Polling) and DQ6/DQ2
(toggle bits). After a program or erase cycle has been completed, the device au-
tomatically returns to the read mode.
The sector erase architecture allows memory sectors to be erased and repro-
grammed without affecting the data contents of other sectors. The device is fully
erased when shipped from the factory.
Hardware data protection measures include a low VCC detector that automat-
ically inhibits write operations during power transitions. The hardware sector
protection feature disables both program and erase operations in any combina-
tion of the sectors of memory. This can be achieved in-system or via
programming equipment.
The device offers two power-saving features. When addresses have been stable
for a specified amount of time, the device enters the automatic sleep mode.
The system can also place the device into the standby mode. Power consump-
tion is greatly reduced in both modes.
