40MX and 42MX FPGA Families
G en er al D e sc r i p t i on

Actel’s 40MX and 42MX families offer a cost-effective design
solution at 5V. The MX devices are single-chip solutions and
provide high performance while shortening the system
design and development cycle. MX devices can integrate and
consolidate logic implemented in multiple PALs, CPLDs,
and FPGAs. Example applications include high-speed
controllers and address decoding, peripheral bus interfaces,
DSP, and co-processor functions.
The MX device architecture is based on Actel’s patented
antifuse technology implemented in a 0.45µm triple-metal
CMOS process. With capacities ranging from 3,000 to 54,000
system gates, the MX devices provide performance up to
250 MHz, are live on power-up and have one-fifth the
standby power consumption of comparable FPGAs. Actel’s
MX FPGAs provide up to 202 user I/Os and are available in a
wide variety of packages and speed grades.
Actel’s A42MX24 and A42MX36 devices also feature
MultiPlex I/Os, which support mixed-voltage systems,
enable programmable PCI, deliver high-performance
operation at both 5.0V and 3.3V, and provide a low-power
mode. The devices are fully compliant with the PCI Local
Bus Specification (version 2.1). They deliver 200 MHz
on-chip operation and 6.1 ns clock-to-output performance.
The 42MX24 and 42MX36 devices include system-level
features such as IEEE Standard 1149.1 (JTAG) Boundary
Scan Testing and fast wide-decode modules. In addition, the
A42MX36 device offers dual-port SRAM for implementing
fast FIFOs, LIFOs, and temporary data storage. The storage
elements can efficiently address applications requiring wide
datapath manipulation and can perform transformation
functions such as those required for telecommunications,
networking, and DSP.
All MX devices are fully tested over automotive and military
temperature ranges. In addition, the largest member of the
family, the A42MX36, is available in both CQ208 and CQ256
ceramic packages screened to MIL-STD-883 levels. For easy
prototyping and conversion from plastic to ceramic, the
CQ208 and PQ208 devices are pin-compatible.
The MX 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 fast logic designs. In addition, the
A42MX36 device contains embedded dual-port SRAM
modules, which are optimized for high-speed datapath
functions such as FIFOs, LIFOs and scratchpad memory.
A42MX24 and A42MX36 also contain wide-decode modules.
Lo gic Mod ule s
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. 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; latches and flip-flops can be
constructed from logic modules whenever required in the
application.

The 42MX devices contain three types of logic modules:
combinatorial (C-modules), sequential (S-modules) and
decode (D-modules).
Figure 2
illustrates the combinatorial
logic module. The S-module, shown in
Figure 3,
implements
the same combinatorial logic function as the C-module
while adding a sequential element. The sequential element
can be configured as either a D-flip-flop or a transparent
latch. The S-module register can be bypassed so that it
implements purely combinatorial logic.
