iCE40™ HX Field Programmable Gate Array (FPGA) IC 96 65536 1280 144-LQFP

General Description

The iCE40 family architecture contains an array of Programmable Logic Blocks (PLB), sysCLOCK™ PLLs, Nonvolatile

Programmable Configuration Memory (NVCM) and blocks of sysMEM™ Embedded Block RAM (EBR) surrounded by

Programmable I/O (PIO). 

The logic blocks, Programmable Logic Blocks (PLB) and sysMEM EBR blocks, are arranged in a two-dimensional grid with

rows and columns. Each column has either logic blocks or EBR blocks. The PIO cells are located at the periphery of the

device, arranged in banks. The PLB contains the building blocks for logic, arithmetic, and register functions. The PIOs

utilize a flexible I/O buffer referred to as a sysIO buffer that supports operation with a variety of interface standards. The

blocks are connected with many vertical and horizontal routing channel resources. Theplace and route software tool

automatically allocates these routing resources.

In the iCE40 family, there are up to four independent sysIO banks. Note on some packages VCCIO banks are tied together.

There are different types of I/O buffers on the different banks. Refer to the details in later sections of this document.

The sysMEM EBRs are large 4 kbit, dedicated fast memory blocks. These blocks can be configured as RAM, ROM or FIFO.

The iCE40 architecture also provides up to two sysCLOCK Phase Locked Loop (PLL) 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 SPI port that supports programming and configuration of the device. The iCE40 includes

on-chip, Nonvolatile Configuration Memory (NVCM).

MachXO3 Field Programmable Gate Array (FPGA) IC 38 75776 2112 49-UFBGA, WLCSP

General Description

MachXO3™ device family is an Ultra-Low Density family that supports the most advanced programmable bridging and

I/O expansion. It has the breakthrough I/O density and the lowest cost per I/O. The device I/O features have the

integrated support for latest industry standard I/O.

The MachXO3L/LF family of low power, instant-on, non-volatile PLDs has five devices with densities ranging from 640 to

9400 Look-Up Tables (LUTs). In addition to LUT-based, low-cost programmable logic these devices feature Embedded

Block RAM (EBR), Distributed RAM, Phase Locked Loops (PLLs), pre-engineered 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. MachXO3LF devices also support User Flash Memory (UFM). These features

allow these devices to be used in low cost, high volume applications such as consumer electronics, compute and storage,

wireless communications, industrial control, and automotive systems.

The MachXO3L/LF 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/O 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 MachXO3L/LF devices are available in two versions C and E with two speed grades: -5 and -6, with -6 being the

fastest. C devices have an internal linear voltage regulator which supports external VCC supply voltages of 3.3 V or 2.5 V.

E devices only accept 1.2 V as the external VCC supply voltage. With the exception of power supply voltage both C and E

are functionally compatible with each other.

The MachXO3L/LF PLDs are available in a broad range of advanced halogen-free packages ranging from the space saving

2.5 x 2.5 mm WLCSP to the 19 x 19 mm caBGA. MachXO3L/LF 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 MachXO3L/LF devices offer enhanced I/O features  such as drive strength control, slew rate control, PCI compatibility,

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

MachXO3L/LF 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, keyboard scanner and similar state machines.

The MachXO3L/LF devices also provide flexible, reliable and secure configuration from on-chip NVCM/Flash. 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, MachXO3L/LF 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

MachXO3L/LF family of devices. Popular logic synthesis tools provide synthesis library support for MachXO3L/LF. Lattice

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

the design in the MachXO3L/LF device. These tools extract the timing from the routing and back-annotate it into the

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 MachXO3L/LF 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.
