40MX and 42MX FPGA Families
Performance
MX devices can operate with internal clock frequencies of 250 MHz, enabling fast execution of complex logic functions.
MX devices are live on power-up and do not require auxiliary configuration devices and thus are an optimal platform to
integrate the functionality contained in multiple programmable logic devices. In addition, designs that previously would
have required a gate array to meet performance can be integrated into an MX device with improvements in cost and
time-to-market. Using timing-driven place-and-route (TDPR) tools, designers can achieve highly deterministic device
performance.
User Security
Microsemi FuseLock provides robust security against design theft. Special security fuses are hidden in the fabric of the
device and protect against unauthorized users attempting to access the programming and/or probe interfaces. It is
virtually impossible to identify or bypass these fuses without damaging the device, making Microsemi antifuse FPGAs
protected with the highest level of security available from 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, there is
the Security Fuse which, when programmed, both disables the probing circuitry and prohibits further programming of
the device.
Programming
Device programming is supported through the Silicon Sculptor series of programmers. Silicon Sculptor II is a compact,
robust, single-site and multi-site device 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 it
test fuses (both programmed and non-programmed), 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, Microsemi offers device volume-programming services either through
distribution partners or via In-House Programming from the factory.

Sculptor II and Silicon Sculptor 3 user guides.
