Programming
Device programming is supported through Silicon
Sculptor series of programmers. In particular, Silicon
Sculptor II are compact, robust, single-site and multi-site
device programmer for the PC.
With standalone software, Silicon Sculptor II allows
concurrent programming of multiple units from the
same PC, ensuring the fastest programming times
possible. Each fuse is subsequently verified by Silicon
Sculptor II to insure correct programming. In addition,
integrity
tests
ensure
that
no
extra
fuses
are
programmed. Silicon Sculptor II also provides extensive
hardware self-testing capability.
The procedure for programming an SX device using
Silicon Sculptor II are as follows:
1. Load the .AFM file
2. Select the device to be programmed
3. Begin programming
When the design is ready to go to production, Actel
offers
device
volume-programming
services
either
through
distribution
partners
or
via
in-house
programming from the factory.

Notes:
1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. Exposure to absolute
maximum rated conditions for extended periods may affect device reliability. Device should not be operated outside the
Recommended Operating Conditions.
2. VCCR in the A54SX16P must be greater than or equal to VCCI during power-up and power-down sequences and during normal
operation.
3. Device inputs are normally high impedance and draw extremely low current. However, when input voltage is greater than VCC +
0.5 V or less than GND – 0.5 V, the internal protection diodes will forward-bias and can draw excessive current.
