GENERAL DESCRIPTION
The MACH

1 & 2 families from Lattice/Vantis offer high-performance, low cost Compl
Programmable Logic Devices (CPLDs), addressing the growing need for speed in netwo
telecommunications and computing. MACH 1 & 2 devices are available in speeds as fast
t

and in densities ranging from 32 to 128 macrocells (Tables 1 and 2). The overall be
users include guaranteed high performance for entry-to-mid-level logic needs at a low

The MACH 1 & 2 families consist of ten devices—five base options, each with a counte
includes JTAG-compatible in-system programming (ISP). These devices offer five differen
I/O combinations in Thin Quad Flat Pack (TQFP), Plastic Quad Flat Pack (PQFP), and P
Leaded Chip Carrier (PLCC) packages from 44 to 100 pins (Table 3). Each MACH 1 & 2
PCI compliant and includes other features such as SpeedLocking architecture for guarant
timing, Bus-Friendly inputs and I/Os, and programmable power-down mode for extra p
savings.

1. The MACH110, MACH120, MACH130, MACH210, MACHLV210, MACH215, MACH220 and MACH230 are not liste
not recommended for new designs. However, they are still supported by Lattice/Vantis. For technical or sales suppo

DesignDirect development systems. The DesignDirect development system is the Lattice
implementation software that includes support for all Lattice/Vantis CPLD, FPGA, and S
devices. This system is supported under Windows ’95, ’98 and NT as well as Sun Solaris a
DesignDirect software is designed for use with design entry, simulation and verification
from leading-edge tool vendors such as Cadence, Exemplar Logic, Mentor Graphics, Mo
Technology, Synopsys, Synplicity, Viewlogic and others. It accepts EDIF 2 0 0 input ne
generates JEDEC files for Lattice/Vantis PLDs and creates industry-standard EDIF, Verilo
compliant VHDL and SDF simulation netlists for design verification.
DesignDirect software is also available in product configurations that include VHDL and
synthesis from Exemplar Logic and VHDL, Verilog RTL and gate level timing simulation fro

FUNCTIONAL DESCRIPTION
Each MACH 1 and 2 device consists of multiple, optimized PAL
®
blocks interconnected by
matrix. The switch matrix allows communication between PAL blocks, and routes inputs t
blocks. Together, the PAL blocks and switch matrix allow the logic designer to create larg
in a single device instead of using multiple devices.

Figure 1. Overall Architecture of MACH 1 & 2 Devices
The switch matrix takes all dedicated inputs and signals from the input switch matrices a
them as needed to the PAL blocks. Feedback signals that return to the same PAL block
go through the switch matrix. This mechanism ensures that PAL blocks in MACH device
communicate with each other with guaranteed fixed timing (SpeedLocking).
The switch matrix makes a MACH device more advanced than simply several PAL dev
single chip. It allows the designer to think of the device not as a collection of blocks,
single programmable device; the software partitions the design into PAL blocks throu
central switch matrix so that the designer does not have to be concerned with the int
architecture of the device.

Each PAL block consists of the following elements:
x
Product-term array
x
Logic Allocator
x
Macrocells
x
I/O cells
Each PAL block additionally contains an asynchronous reset product term and an async
preset product term. This allows the flip-flops within a single PAL block to be initialized a
There are also output enable product terms that provide tri-state control for the I/O cel
Product-Term Array
The product-term array consists of a number of product terms that form the basis of the lo
implemented. The inputs to the AND gates come from the switch matrix (Table 4), and
provided in both true and complement forms for efficient logic implementation.
Because the number of product terms available for a given function is not fixed, the ful
products is not realized in the array. The product terms drive the logic allocator, which
the appropriate number of product terms to generate the function.

Logic Allocator
The logic allocator (Figure 2) is a block within which different product terms are allocat
appropriate macrocells in groups of four product terms called “product term clusters”. T
availability and distribution of product term clusters is automatically considered by the so
it fits functions within the PAL block. The size of the product term clusters has been de
provide high utilization of product terms. Complex functions using many product terms
possible, and when few product terms are used, there will be a minimal number of unu
wasted, product terms left over.
The product term clusters do not “wrap” around the logic block. This means that the m
at the ends of the block have fewer product terms available (Tables 5, 6, 7, 8).
