DESCRIPTION
The X25F064/032/016/008 family are 8/16/32/64K-bit
CMOS SerialFlash memory, internally organized
X 8. They feature a “Univolt” Program and Read voltage,
Serial Peripheral Interface (SPI), and software protocol
allowing operation on a simple three-wire bus. The bus
signals are a clock input (SCK), plus separate data in
(SI) and data out (SO) lines. Access to the device is
controlled through a chip select (
CS
) input, allowing any
number of devices to share the same bus.
The X25F064/032/016/008 also features two additional
inputs that provide the end user with added flexibility. By
asserting the
HOLD
input, the X25F064/032/016/008
will ignore transitions on its inputs, thus allowing the host
to service higher priority interrupts. The
PP
input can be
used as a hardwire input to the X25F064/032/016/008
disabling all program attempts to the status register,
thus providing a mechanism for limiting end user capa-
bility of altering 0, 1/4, 1/2, or all of the memory.
The X25F064/032/016/008 utilizes Xicor’s proprietary
flash cell, providing a minimum endurance
of 100,000 cycles and a minimum data retention of
100 years.
