Data Protection
The CY14B104L/CY14B104N protects data from corruption
during low-voltage conditions by inhibiting all externally
initiated STORE and write operations. The low voltage
condition
is
detected
when
VCC < VSWITCH. If the
CY14B104L/CY14B104N is in a write mode (both CE and WE
low) at power up, after a RECALL, or after a STORE, the write
will be inhibited until a negative transition on CE or WE is
detected. This protects against inadvertent writes during
power up or brown out conditions.
Noise Considerations
Refer CY Application Note AN1064.
