Introduction
MachXO Family Data Sheet
The devices use look-up tables (LUTs) and embedded block memories traditionally associated with FPGAs for flex-
ible and efficient logic implementation. Through non-volatile technology, the devices provide the single-chip, high-
security, instant-on capabilities traditionally associated with CPLDs. Finally, advanced process technology and
careful design will provide the high pin-to-pin performance also associated with CPLDs.
The ispLEVER
®
design tools from Lattice allow complex designs to be efficiently implemented using the MachXO
family of devices. Popular logic synthesis tools provide synthesis library support for MachXO. The ispLEVER tools
use the synthesis tool output along with the constraints from its floor planning tools to place and route the design in
the MachXO device. The ispLEVER tool extracts the timing from the routing and back-annotates it into the design
for timing verification.

MachXO Family Data Sheet
Architecture

Data Sheet DS1002
Architecture Overview
The MachXO family architecture contains an array of logic blocks surrounded by Programmable I/O (PIO). Some
devices in this family have sysCLOCK PLLs and blocks of sysMEM™ Embedded Block RAM (EBRs). Figures 2-1,
2-2, and 2-3 show the block diagrams of the various family members.
The logic blocks are arranged in a two-dimensional grid with rows and columns. The EBR blocks are arranged in a
column to the left of the logic array. The PIO cells are located at the periphery of the device, arranged into Banks.
The PIOs utilize a flexible I/O buffer referred to as a sysIO interface that supports operation with a variety of inter-
face standards. The blocks are connected with many vertical and horizontal routing channel resources. The place
and route software tool automatically allocates these routing resources.
There are two kinds of logic blocks, the Programmable Functional Unit (PFU) and the Programmable Functional
unit without RAM (PFF). The PFU contains the building blocks for logic, arithmetic, RAM, ROM, and register func-
tions. The PFF block contains building blocks for logic, arithmetic, ROM, and register functions. Both the PFU and
PFF blocks are optimized for flexibility, allowing complex designs to be implemented quickly and effectively. Logic
blocks are arranged in a two-dimensional array. Only one type of block is used per row.
In the MachXO family, the number of sysIO Banks varies by device. There are different types of I/O Buffers on dif-
ferent Banks. See the details in later sections of this document. The sysMEM EBRs are large, dedicated fast mem-
ory blocks; these blocks are found only in the larger devices. These blocks can be configured as RAM, ROM or
FIFO. FIFO support includes dedicated FIFO pointer and flag “hard” control logic to minimize LUT use.
The MachXO registers in PFU and sysI/O can be configured to be SET or RESET. After power up and device is
configured, the device enters into user mode with these registers SET/RESET according to the configuration set-
ting, allowing device entering to a known state for predictable system function.
The MachXO architecture provides up to two sysCLOCK™ Phase Locked Loop (PLL) blocks on larger devices.
These blocks are located at either end of the memory blocks. The PLLs have multiply, divide, and phase shifting
capabilities that are used to manage the frequency and phase relationships of the clocks.
Every device in the family has a JTAG Port that supports programming and configuration of the device as well as
access to the user logic. The MachXO devices are available for operation from 3.3V, 2.5V, 1.8V, and 1.2V power
supplies, providing easy integration into the overall system.
