I/O Modules
The I/O modules provide the interface between the
device pins and the logic array.
diagram of the 42MX I/O module. A variety of user
functions, determined by a library macro selection, can
be implemented in the module. (Refer to the
Macro Library Guide
modules contain tristate buffers, with input and output
latches that can be configured for input, output, or
bidirectional operation.
42MX devices contain flexible I/O structures, where each
output pin has a dedicated output-enable control

addition, the Actel Designer software tools can build a D-
type flip-flop using a C-module combined with an I/O
module to register input and output signals. Refer to the
Antifuse Macro Library Guide
Actel's Designer software development tools provide a
design library of I/O macro functions that can implement
all I/O configurations supported by the MX FPGAs.
Note: *Can be configured as a Latch or D Flip-Flop (Using

User Security
The Actel FuseLock provides robust security against
design theft. Special security fuses are hidden in the
fabric of the device and prevent unauthorized users from
accessing the programming and/or probe interfaces. It is
virtually impossible to identify or bypass these fuses
without damaging the device, making Actel antifuse
FPGAs immune to both invasive and noninvasive attacks.
Special security fuses in 40MX devices include the Probe
Fuse and Program Fuse. The former disables the probing
circuitry while the latter prohibits further programming
of all fuses, including the Probe Fuse. In 42MX devices,

Programming
Device programming is supported through the Silicon
Sculptor series of programmers. Silicon Sculptor II is a
compact,
programmer for the PC. With standalone software,
Silicon Sculptor II is designed to allow concurrent
programming of multiple units from the same PC.
Silicon Sculptor II programs devices independently to
achieve the fastest programming times possible. After
being programmed, each fuse is verified to insure that it
has been programmed correctly. Furthermore, at the end
of programming, there are integrity tests that are run to
ensure no extra fuses have been programmed. Not only
does
nonprogrammed), Silicon Sculptor II also allows self-test
to verify its own hardware extensively.
The procedure for programming an MX device using
Silicon Sculptor II is 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
