M58LW032D
When the Program/Erase Controller is idle, or sus-
pended, STS can float High through a pull-up re-
sistor. The use of an open-drain output allows the
STS pins from several memories to be connected
to a single pull-up resistor (a Low will indicate that
one, or more, of the memories is busy).
STS is not Low during a reset unless the reset was
applied when the Program/Erase controller was
active.
Program/Erase Enable (VPEN). The Program/
Erase Enable input, VPEN, is used to protect all
blocks, preventing Program and Erase operations
from affecting their data.
Program/Erase Enable must be kept High during
all Program/Erase Controller operations, other-
wise the operations is not guaranteed to succeed
and data may become corrupt.
VDD Supply Voltage. VDD provides the power
supply to the internal core of the memory device.
It is the main power supply for all operations
(Read, Program and Erase).
VDDQ Supply Voltage. VDDQ provides the power
supply to the I/O pins and enables all Outputs to
be powered independently from VDD. VDDQ can be
tied to VDD or can use a separate supply.
It is recommended to power-up and power-down
VDD and VDDQ together to avoid any condition that
would result in data corruption.
VSS Ground. Ground, VSS, is the reference for
the core power supply. It must be connected to the
system ground.
VSSQ Ground. VSSQ ground is the reference for
the input/output circuitry driven by VDDQ. VSSQ
must be connected to VSS.
Note: Each device in a system should have
VDD and VDDQ decoupled with a 0.1µF ceramic
capacitor close to the pin (high frequency, in-
herently low inductance capacitors should be
as close as possible to the package). See Fig-
ure 8., AC Measurement Load Circuit.
