GENERAL DESCRIPTION
The MACH
®
5 family consists of a broad range of high-density and high-I/O Complex
Programmable Logic Devices (CPLDs). The fifth-generation MACH architecture yields fast speeds
at high CPLD densities, low power, and supports additional features such as in-system
programmability, Boundary Scan testability, and advanced clocking options (Table 1). The MACH
5 family offers 5-V (M5-xxx) and 3.3-V (M5LV-xxx) operation.
Manufactured in state-of-the-art ISO 9000 qualified fabrication facilities on E
2
CMOS process
technologies, MACH 5 devices are available with pin-to-pin delays as fast as 5.5 ns (Table 2). The
5.5, 6.5, 7.5, 10, and 12-ns devices are compliant with the
PCI Local Bus Specification
.

2. /1 version recommended for new designs
With Lattice’s unique hierarchical architecture, the MACH 5 family provides densities up to 512
macrocells to support full system logic integration. Extensive routing resources ensure pinout
retention as well as high utilization. It is ideal for PAL
®
block device integration and a wide range
of other applications including high-speed computing, low-power applications, communications,
and embedded control. At each macrocell density point, Lattice offers several I/O and package
options to meet a wide range of design needs (Table 3).

Advanced power management options allow designers to incrementally reduce power while
maintaining the level of performance needed for today’s complex designs. I/O safety features
MACH 5 Family
3
allow for mixed-voltage design, and both the 3.3-V and the 5-V device versions are in-system
programmable through an IEEE 1149.1 Test Access Port (TAP) interface.
FUNCTIONAL DESCRIPTION
The MACH 5 architecture consists of PAL blocks connected by two levels of interconnect. The
block
interconnect
provides routing among 4 PAL blocks. This grouping of PAL blocks joined by the
block interconnect is called a
segment
. The second level of interconnect, the
segment
interconnect
, ties all of the segments together. The only logic difference between any two MACH
5 devices is the number of segments. Therefore, once a designer is familiar with one device,
consistent performance can be expected across the entire family. All devices have four clock pins
available which can also be used as logic inputs.

The MACH 5 PAL blocks consist of the elements listed below (Figure 2). While each PAL block
resembles an independent PAL device, it has superior control and logic generation capabilities.

I/O Cells
The I/Os associated with each PAL block have a path directly back to that PAL block called
local
feedback
. If the I/O is used in another PAL block, the
interconnect feeder
assigns a
block interconnect
line to that signal. The interconnect feeder acts as an input switch matrix. The block and segment
interconnects provide connections between any two signals in a device. The
block feeder
assigns
block interconnect lines and local feedback lines to the PAL block inputs.

Figure 2. PAL Block Structure
Product-Term Array and Logic Allocator
The product-term array uses the same sum-of-products architecture as PAL devices and consists of
32 inputs (plus their complements) and 64 product terms arranged in 16
clusters
. A cluster is a sum-
of-products function with either 3 of 4 product terms.
Logic allocators
assign the clusters to macrocells. Each macrocell can accept up to eight clusters of
three or four product terms, but a given cluster can only be steered to one macrocell (Table 4). If
only three product terms in a cluster are steered, the fourth can be used as an input to an XOR
gate for separate logic generation and/or polarity control.
The
wide logic allocator
is comprised of all 16 of the individual logic allocators and acts as an output
switch matrix by reassigning logic to macrocells to retain pinout as designs change. The logic
allocation scheme in the MACH 5 device allows for the implementation of large equations (up to
32 product terms) with only one pass through the logic array.
