The 40MX FPGAs will operate in 5.0V-only systems or
3.3V-only systems.

Mixed Voltage Power Up and Power
Down
When powering up the device in the mixed voltage mode
(V
CCA
= 5.0V and V
CCI
= 3.3V), V
CCA
must be greater than or
equal to V
CCI
throughout the power-up sequence. If V
CCI
is
0.5V greater than V
CCA
when both are above 1.5V, then the
I/Os
input protection junction on the I/Os will be forward
biased, causing them to draw large amounts of current.
When V
CCA
and V
CCI
are in the 1.5V to 2.0V region and V
CCI
is greater than V
CCA
, all I/Os would momentarily behave as
outputs that are in a logical high state, and I
CC
rises to high
levels. For power down, any sequence with V
CCA
and V
CCI
can be implemented.
Low Power Mode
The 42MX devices have a power-saving feature enabled by a
special Low Power pin (LP). In this mode, the device
consumes very minimal power, with standby current as low
as 15μA (see
Electrical Specifications
on page 13
and
14
).
All μ I/Os are tristated, all input buffers are turned off, and
the core of the device is turned off. Since the core is turned
off, the state of the registers and the contents of the SRAM
are lost. The device enters low power mode 800ns after the
LP pin is set High. It will resume normal operation 200μs
after the LP pin is driven to a logic Low.
MX Architectural Overview
The 40MX and 42MX devices are composed of fine-grained
building blocks that enable fast, efficient logic designs. All
devices within these families are composed of logic
modules, I/O modules, routing resources, and clock
networks, which are the building blocks for designing fast
logic designs. In addition, the A42MX36 device contains
embedded dual-port SRAM and wide decode modules. The
dual-port SRAM modules are optimized for high-speed
datapath functions such as FIFOs, LIFOs, and scratchpad
memory. The
Product Profile
on page 1
lists the specific
logic resources contained within each device.
Logic Modules
The 40MX logic module is an eight-input, one-output logic
circuit designed to implement a wide range of logic
functions with efficient use of interconnect routing
resources (
Figure 1
).
The logic module can implement the four basic logic
functions (NAND, AND, OR, and NOR) in gates of two, three,
or four inputs. Each function may have many versions with
different combinations of active LOW inputs. The logic
module can also implement a variety of D-latches,
exclusivity functions, AND-ORs, and OR-ANDs. No dedicated
hard-wired latches or flip-flops are required in the array,
since latches and flip-flops can be constructed from logic
modules wherever needed in the application.
