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.
