MachXO2 Field Programmable Gate Array (FPGA) IC 114 94208 4320 144-LQFP

General Description

The MachXO2 family of ultra low power, instant-on, non-volatile PLDs has six devices with densities ranging from 256 to

6864 Look-Up Tables (LUTs). In addition to LUT-based, low-cost programmable logic these devices feature Embedded

Block RAM (EBR), Distributed RAM, User Flash Memory (UFM), Phase Locked Loops (PLLs), preengineered source

synchronous I/O support, advanced configuration support including dual-boot capability and hardened versions of

commonly used functions such as SPI controller, I²C controller and timer/counter. These features allow these devices to

be used in low cost, high volume consumer and system applications.

The MachXO2 devices are designed on a 65 nm non-volatile low power process. The device architecture has several

features such as programmable low swing differential I/Os and the ability to turn off I/O banks, on-chip PLLs and

oscillators dynamically. These features help manage static and dynamic power consumption resulting in low static power

for all members of the family.

The MachXO2 devices are available in two versions – ultra low power (ZE) and high performance (HC and HE) devices.

The ultra low power devices are offered in three speed grades –1, –2 and –3, with –3 being the fastest. Similarly, the

high-performance devices are offered in three speed grades: –4, –5 and –6, with –6 being the fastest. HC devices have an

internal linear voltage regulator which supports external VCC supply voltages of 3.3 V or 2.5 V. ZE and HE devices only

accept 1.2 V as the external VCC supply voltage. With the exception of power supply voltage all three types of devices

(ZE, HC and HE) are functionally compatible and pin compatible with each other.

The MachXO2 PLDs are available in a broad range of advanced halogen-free packages ranging from the space saving

2.5 mm x 2.5 mm WLCSP to the 23 mm x 23 mm fpBGA. MachXO2 devices support density migration within the same

package. Table 1-1 shows the LUT densities, package and I/O options, along with other key parameters.

The pre-engineered source synchronous logic implemented in the MachXO2 device family supports a broad range of

interface standards, including LPDDR, DDR, DDR2 and 7:1 gearing for display I/Os.

The MachXO2 devices offer enhanced I/O features such as drive strength control, slew rate control, PCI compati bility,

bus-keeper latches, pull-up resistors, pull-down resistors, open drain outputs and hot socketing. Pull-up, pull-down and

bus-keeper features are controllable on a“per-pin”basis.

A user-programmable internal oscillator is included in MachXO2 devices. The clock output from this oscillator may be

divided by the timer/counter for use as clock input in functions such as LED control, key-board scanner and sim-ilar state

machines.

The MachXO2 devices also provide flexible, reliable and secure configuration from on-chip Flash memory. These devices

can also configure themselves from external SPI Flash or be configured by an external master through the JTAG test

access port or through the I2C port. Additionally, MachXO2 devices support dual-boot capability (using external Flash

memory) and remote field upgrade (TransFR) capability.

Lattice provides a variety of design tools that allow complex designs to be efficiently implemented using the MachXO2

family of devices. Popular logic synthesis tools provide synthesis library support for MachXO2. Lattice design tools use the

synthesis tool output along with the user-specified preferences and constraints to place and route the design in the

MachXO2 device. These tools extract the timing from the routing and back-annotate it intothe design for timing

verification.

Lattice provides many pre-engineered IP (Intellectual Property) LatticeCORE™ modules, including a number of reference

designs licensed free of charge, optimized for the MachXO2 PLD family. By using these configurable soft core IP cores as

standardized blocks, users are free to concentrate on the unique aspects of their design, increasing their productivity.

MachXO Field Programmable Gate Array (FPGA) IC 113 28262 2280 144-LQFP

General Description

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). 

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 memory 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.
