SAFE FOR MIXED SUPPLY VOLTAGE SYSTEM DESIGNS 1
Both the 3.3-V and 5-V VCC MACH 5 devices are safe for mixed supply voltage system designs.
The 5-V devices will not overdrive 3.3-V devices above the output voltage of 3.3 V, while they
accept inputs from other 3.3-V devices. The 3.3-V devices will accept inputs up to 5.5 V. Both the
3.3-V and 5-V versions have the same high-speed performance and provide easy-to-use mixed-
voltage design capability.
Note:
1. Excludes original M5-128, M5-192, and M5-256 while M5-128/1, M3-192/1 and M5-256/1 are supported. Please refer to
Application Note titled “Hot Socketing and Mixed Supply Design with MACH 4 and MACH 5 Devices”.
BUS-FRIENDLY INPUTS AND I/OS
All MACH 5 devices have inputs and I/Os which feature the Bus-Friendly circuitry incorporating
two inverters in series which loop back to the input. This double inversion weakly holds the input
at its last driven logic state. While it is a good design practice to tie unused pins to a known state,
the Bus-Friendly input structure pulls pins away from the input threshold voltage where noise can
cause high-frequency switching. At power-up, the Bus-Friendly latches are reset to a logic level
“1.” For the circuit diagram, please refer to the document entitled MACH Endurance
Characteristics on the Lattice Data Book CD-ROM or Lattice web site.
POWER MANAGEMENT
There are 4 power/speed options in each MACH 5 PAL block (Table 5). The speed and power
tradeoff can be tailored for each design. The signal speed paths in the lower-power PAL blocks
will be slower than those in the higher-power PAL blocks. This feature allows speed critical paths
to run at maximum frequency while the rest of the signal paths operate in a lower-power mode.
In large designs, there may be several different speed requirements for different portions of the
design.
PROGRAMMABLE SLEW RATE
Each MACH 5 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
