Characteristics subject to change without notice
Figure 2 shows the maximum pulse duration of
negative-going VCC transients that do not cause a reset
condition. As the amplitude of the transient goes further
below the threshold (increasing VTH - VCC), the
maximum pulse duration decreases. In this test, the
VCC starts from an initial voltage of 0.5V above the
threshold and drops below it by the amplitude of the
overdrive voltage (VTH - VCC).
EMBEDDED EEPROM DESCRIPTION
The CAT15008/16 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 CAT15008/16 is accom–
plished by simply providing the READ command and an
address. Writing to the CAT15008/16, 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.
After a high to low transition on the CS
input pin, the
CAT15008/16 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.
