Hold Operation
The HOLD
input can be used to pause communication
between host and CAT25010/20/40. To pause, HOLD
must be taken low while SCK is low (Figure 10).
During the hold condition the device must remain
selected (CS
low). During the pause, the data output
pin (SO) is tri-stated (high impedance) and SI
transitions are ignored. To resume communication,
HOLD
must be taken high while SCK is low.
DESIGN CONSIDERATIONS
The CAT25010/20/40 devices incorporate Power-On
Reset (POR) circuitry which protects the internal logic
against powering up in the wrong state. The device
will power up into Standby mode after VCC exceeds
the POR trigger level and will power down into Reset
mode when VCC drops below the POR trigger level.
This bi-directional POR behavior protects the device
against ‘brown-out’ failure following a temporary loss
of power.
The CAT25010/20/40 device powers up in a write
disable state and in a low power standby mode. A
WREN instruction must be issued prior any writes to
the device.
After power up, the CS
pin must be brought low to
enter a ready state and receive an instruction. After a
successful byte/page write or status register write, the
device goes into a write disable mode. The CS
input
must be set high after the proper number of clock
cycles to start the internal write cycle. Access to the
memory array during an internal write cycle is ignored
and programming is continued. Any invalid op-code
will be ignored and the serial output pin (SO) will
remain in the high impedance state.
