DESCRIPTION
The X25020 is a CMOS 2048-bit serial EEPROM,
internally organized as 256 x 8. The X25020 features a
serial interface and software protocol, allowing opera-
tion 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 X25020 also features two additional inputs that
provide the end user with added flexibility. By asserting
the HOLD input, the X25020 will ignore transitions on
its inputs, thus allowing the host to service higher pri-
ority interrupts. The WP input can be used as a hard-
wire input to the X25020 (disabling all write attempts),
thus providing a mechanism for limiting end user capa-
bility of altering the memory.
The X25020 utilizes Xicor’s proprietary Direct Write
cell, providing a minimum endurance of 1,000,000
cycles per byte and a minimum data retention of 100
years.
