2.4
WP (24VL024 only)
This is a bidirectional pin used to transfer addresses
and data into and out of the device. It is an open drain
terminal. Therefore, the SDA bus requires a pull-up
resistor to V CC (typical 10 k Ω for 100 kHz, 2 k Ω for
400 kHz).
WP is the hardware write-protect pin. It must be tied to
V CC or V SS . If tied to V CC , the hardware write protection
is enabled and will protect the entire array (00h-FFh). If
the WP pin is tied to V SS the hardware write protection
is disabled.
For normal data transfer, SDA is allowed to change
only during SCL low. Changes during SCL high are
2.5
Noise Protection
reserved for indicating the Start and Stop conditions.
The 24VL024/24VL025 employs a V CC threshold
2.2
SCL Serial Clock
detector circuit that disables the internal erase/write
logic if the V CC is below 1.0 volts at nominal conditions.
The SCL input is used to synchronize the data transfer
to and from the device.
The SCL and SDA inputs have Schmitt Trigger and
filter circuits that suppress noise spikes to assure
proper device operation even on a noisy bus.
2.3
A0, A1, A2
The A0, A1 and A2 inputs are used by the 24VL024/
24VL025 for multiple device operations. The levels on
these inputs are compared with the corresponding bits
in the slave address. The chip is selected if the
compare is true.
Up to eight 24VL024/24VL025 devices (four for the
SOT-23 package) may be connected to the same bus
by using different Chip Select bit combinations. These
inputs must be connected to either V CC or V SS .
In most applications, the chip address inputs A0, A1
and A2 are hard-wired to logic ‘ 0 ’ or logic ‘ 1 ’. For
applications in which these pins are controlled by a
microcontroller or other programmable device, the chip
address pins must be driven to logic ‘ 0 ’ or logic ‘ 1 ’
before normal device operation can proceed.
