DESCRIPTION
The low voltage X4C105 combines several functions into
one device. The first is a 2-wire, 4Kbit serial EEPROM
memory with write protection. A Write Protect (WP) pin
provides hardware protection for the upper half of this
memory against inadvertent writes.
A one nibble NOVRAM is provided and occupies a single
location. This allows access of 4 bits in a single 150ns
cycle. This is useful for tracking system operation or
process status. The NOVRAM memory is completely
isolated from the serial memory section.
A low voltage detect circuit activates a RESET pin when
Vcc drops below 3V. This signal also blocks new read or
write operations and initiates a NOVRAM AUTOSTORE.
The AUTOSTORE operation is powered by an external
capacitor to ensure that the value in the NOVRAM is
always maintained in the event of a power failure.
The four NOVRAM bits also appear on four seperate
output pins to allow continuous control of external
circuitry, such as ASICs.
Xicor EEPROMs are designed and tested for
applications requiring extended endurance. Inherent data
retention is greater than 100 years.
