ispMACH 4A Family
GENERAL DESCRIPTION
The ispMACH
™
4A family from Lattice offers an exceptionally flexible architecture and delivers
a superior Complex Programmable Logic Device (CPLD) solution of easy-to-use silicon products
and software tools. The overall benefits for users are a guaranteed and predictable CPLD
solution, faster time-to-market, greater flexibility and lower cost. The ispMACH 4A devices offer
densities ranging from 32 to 512 macrocells with 100% utilization and 100% pin-out retention.
The ispMACH 4A families offer 5-V (M4A5-xxx) and 3.3-V (M4A3-xxx) operation.
ispMACH 4A products are 5-V or 3.3-V in-system programmable through the JTAG (IEEE Std.
1149.1) interface. JTAG boundary scan testing also allows product testability on automated test
equipment for device connectivity.
All ispMACH 4A family members deliver First-Time-Fit and easy system integration with pin-out
retention after any design change and refit. For both 3.3-V and 5-V operation, ispMACH 4A
products can deliver guaranteed fixed timing as fast as 5.0 ns t
PD
and 182 MHz f
CNT
through the
SpeedLocking feature when using up to 20 product terms per output (Table 2).

ispMACH 4A Family

The ispMACH 4A family offers 20 density-I/O combinations in Thin Quad Flat Pack (TQFP),
Plastic Quad Flat Pack (PQFP), Plastic Leaded Chip Carrier (PLCC), Ball Grid Array (BGA), fine-
pitch BGA (fpBGA), and chip-array BGA (caBGA) packages ranging from 44 to 388 pins (Table
3). It also offers I/O safety features for mixed-voltage designs so that the 3.3-V devices can accept
5-V inputs, and 5-V devices do not overdrive 3.3-V inputs. Additional features include Bus-
Friendly inputs and I/Os, a programmable power-down mode for extra power savings and
individual output slew rate control for the highest speed transition or for the lowest noise
transition.

ispMACH 4A Family
FUNCTIONAL DESCRIPTION
The fundamental architecture of ispMACH 4A devices (Figure 1) consists of multiple, optimized
PAL
®
blocks interconnected by a central switch matrix. The central switch matrix allows
communication between PAL blocks and routes inputs to the PAL blocks. Together, the PAL
blocks and central switch matrix allow the logic designer to create large designs in a single
device instead of having to use multiple devices.
The key to being able to make effective use of these devices lies in the interconnect schemes.
In the ispMACH 4A architecture, the macrocells are flexibly coupled to the product terms
through the logic allocator, and the I/O pins are flexibly coupled to the macrocells due to the
output switch matrix. In addition, more input routing options are provided by the input switch
matrix. These resources provide the flexibility needed to fit designs efficiently.

2. Block clocks do not go to I/O cells in M4A(3,5)-32/32.
3. M4A(3,5)-192, M4A(3,5)-256, M4A3-384, and M4A3-512 have dedicated clock pins which cannot be used as inputs and do
not connect to the central switch matrix.
