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

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

Power Supply
MX devices are designed to operate in both 5.0V and
3.3V environments. In particular, 42MX devices can
operate in mixed 5.0V/3.3V systems.
voltage support of MX devices.
Low Power Mode
42MX devices have been designed with a Low Power
Mode. This feature, activated with setting the special LP
pin to HIGH for a period longer than 800 ns, is
particularly useful for battery-operated systems where
battery life is a primary concern. In this mode, the core of
the device is turned off and the device consumes minimal
power with low standby current. In addition, all input
buffers are turned off, and all outputs and bidirectional
buffers are tristated. Since the core of the device is
turned off, the states of the registers are lost. The device
must be re-initialized when exiting Low Power Mode. I/
Os can be driven during LP mode, and clock pins should
be driven HIGH or LOW and should not float to avoid
drawing current. To exit LP mode, the LP pin must be
pulled LOW for over 200 µs to allow for charge pumps to
power up, and device initialization will begin.
