• Manufacturer Part Number: m58lw032d
• Description: 32 Mbit 4mb X8, 2mb X16, Uniform Block 3v Supply Flash Memory
• Manufacturer: STMicroelectronics

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.

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.

supply to the internal core of the memory device.
It is the main power supply for all operations
(Read, Program and Erase).
