ispMACH 4000 Introduction
The high performance ispMACH 4000 family from Lattice offers a SuperFAST CPLD solution. The family is a blend
of Lattice’s two most popular architectures: the ispLSI
2000 and ispMACH 4A. Retaining the best of both families,
the ispMACH 4000 architecture focuses on signi
fi
cant innovations to combine the highest performance with low
power in a
fl
exible CPLD family.
The ispMACH 4000 combines high speed and low power with the
fl
exibility needed for ease of design. With its
robust Global Routing Pool and Output Routing Pool, this family delivers excellent First-Time-Fit, timing predictabil-
ity, routing, pin-out retention and density migration.
The ispMACH 4000 family offers densities ranging from 32 to 512 macrocells. There are multiple density-I/O com-
binations in Thin Quad Flat Pack (TQFP) and Fine Pitch BGA (fpBGA) packages ranging from 44 to 256 pins/balls.
Table 1 shows the macrocell, package and I/O options, along with other key parameters.
The ispMACH 4000 family has enhanced system integration capabilities. It supports 3.3V (4000V), 2.5V (4000B)
and 1.8V (4000C) supply voltages and 3.3V, 2.5V and 1.8V interface voltages. The ispMACH 4000 also offers
enhanced I/O features such as slew rate control, PCI compatibility, bus-keeper latches, pull-up resistors, pull-down
resistors, open drain outputs and hot socketing. The ispMACH 4000 family members are 3.3V/2.5V/1.8V in-system
programmable through the IEEE Standard 1532 interface. IEEE Standard 1149.1 boundary scan testing capability
also allows product testing on automated test equipment.
Overview
The ispMACH 4000 devices consist of multiple 36-input, 16-macrocell Generic Logic Blocks (GLBs) interconnected
by a Global Routing Pool (GRP). Output Routing Pools (ORPs) connect the GLBs to the I/O Blocks (IOBs), which
contain multiple I/O cells. This architecture is shown in Figure 1.
