MACH 4 Family

POWER MANAGEMENT
Each individual PAL block in MACH 4 devices features a programmable low-power mode, which
results in power savings of up to 50%. The signal speed paths in the low-power PAL block will
be slower than those in the non-low-power PAL block. This feature allows speed critical paths
to run at maximum frequency while the rest of the signal paths operate in the low-power mode.
PROGRAMMABLE SLEW RATE
Each MACH 4 device I/O has an individually programmable output slew rate control bit. Each
output can be individually congured for the higher speed transition (3 V/ns) or for the lower
noise transition (1 V/ns). For high-speed designs with long, unterminated traces, the slow-slew
rate will introduce fewer reections, less noise, and keep ground bounce to a minimum. For
designs with short traces or well terminated lines, the fast slew rate can be used to achieve the
highest speed. The slew rate is adjusted independent of power.
POWER-UP RESET/SET
All ip-ops power up to a known state for predictable system initialization. If a macrocell is
congured to SET on a signal from the control generator, then that macrocell will be SET during
device power-up. If a macrocell is congured to RESET on a signal from the control generator
or is not congured for set/reset, then that macrocell will RESET on power-up. To guarantee
initialization values, the VCC rise must be monotonic, and the clock must be inactive until the
reset delay time has elapsed.
SECURITY BIT
A programmable security bit is provided on the MACH 4 devices as a deterrent to unauthorized
copying of the array conguration patterns. Once programmed, this bit defeats readback of the
programmed pattern by a device programmer, securing proprietary designs from competitors.
Programming and verication are also defeated by the security bit. The bit can only be reset by
erasing the entire device.
