Figure 2 shows the maximum pulse duration of
negative-going V CC transients that do not cause a reset
condition. As the amplitude of the transient goes further
below the threshold (increasing V TH - V CC ), the
maximum pulse duration decreases. In this test, the
V CC starts from an initial voltage of 0.5V above the
threshold and drops below it by the amplitude of the
overdrive voltage (V TH - V CC ).

EMBEDDED EEPROM DESCRIPTION
The CAT15002/04 devices support the Serial Peripheral
Interface (SPI) bus protocol, modes (0,0) and (1,1). The
device contains an 8-bit instruction register. The
instruction set and associated op-codes are listed in
Table 1.
Reading data stored in the CAT15002/04 is accom–
plished by simply providing the READ command and an
address. Writing to the CAT15002/04, in addition to a
WRITE command, address and data, also requires
enabling the device for writing by first setting certain bits
in a Status Register, as will be explained later.
ˉˉ
After a high to low transition on the CS input pin, the
CAT15002/04 will accept any one of the six instruction
op-codes listed in Table 1 and will ignore all other
possible 8-bit combinations. The communication
protocol follows the timing from Figure 3.
