in figure 3, decimal code 5 is equivalent to the binary number
101. Therefore bit 2 (code 4) must be addressed and blown, the
device power supply cycled, and then bit 0 (code 1) addressed
and blown. An appropriate sequence for blowing code 5 is shown
in figure 4. The order of blowing bits, however, is not important.
Blowing bit 0 first, and then bit 2 is acceptable.
Note: After blowing, the programming is not reversible, even
after cycling the supply power. Although a register bit field fuse
cannot be reset after it is blown, additional bits within the same
register can be blown at any time until the device is locked. For
example, if bit 1 (binary 10) has been blown, it is still possible to
blow bit 0. The end result would be binary 11 (decimal code 3).
Locking the Device
After the desired code for each parameter is programmed, the
device can be locked to prevent further programming of any
parameters.
Additional Guidelines
The additional guidelines in this section should be followed to
ensure the proper behavior of these devices:
A 0.1 μF blowing capacitor, C
BLOW, must be mounted between
the VOUT pin and the GND pin during programming, to ensure
enough current is available to blow fuses.
The C
BLOW blowing capacitor must be replaced in the final
application with a suitable CL. (The maximum load capacitance
is 10 nF for proper operation.)
The power supply used for programming must be capable of
delivering at least 26 V and 300 mA.
Be careful to observe the t
LOW delay time before powering
down the device after blowing each bit.
The following programming order is recommended:
POL

TC
2.

4. OUT(Q)
LOCK (only after all other parameters have been pro-

grammed and validated, because this prevents any further
programming of the device)
