| Overview
The iCEstick Evaluation Kit (ICE40HX1K-STICK-EVNICE40HX1K-STICK-EVN) is an easy to use, small size board that allows rapid prototyping of system functions at a very low cost using Lattice Semiconductor's iCE40iCE40 FPGA family. This board has a high-performance, low-power iCE40HX1KiCE40HX1K FPGA on board and has a USB thumb drive form factor. I/O connectors include 16 LVCMOS/LVTTL (3.3 V) digital I/O connections on 0.1” through-hole connections and a 2 x 6 position Digilent Pmod connector for other peripheral connections. The board’s FTDI 2232H USB device allows iCE device programming and UART interface to a PC. Five on-board LEDs can be used to display all sorts of different information, plus the user has access to 16 general-purpose input/output (GPIO) pins. The iCEstick also includes an IrDA (Infrared Data Association) transceiver. IrDA protocols are implemented in a range of portable devices, including mobile phones, laptops, cameras, printers, medical devices, and many more. The board also features a Discera 12 Mhz MEMS oscillator, Micron 32 Mbit N25Q32 SPI flash and is powered directly from the USB connector.
The iCEstick is supported by Lattice iCEcube2 design software for HDL development. Programing the onboard iCE40HX-1k device’s SPI flash is done with Lattice Diamond Programmer.
The Lattice iCE40iCE40 FPGA family comprises ultra-low-density (ULD) devices whose low-cost, small footprint, and extremely small power consumption makes them ideal for a tremendous range of handheld and battery-powered applications. The iCE40 FPGAs are unusual in that they are SRAM-based, which allows them to be reprogrammed on the fly and/or loaded from an external device like an SPI Flash or a microcontroller. However, they also boast one-time programmable (OTP) non-volatile configuration capability, which allows them to be pre-programmed and to run "instant-on" without requiring external configuration.
Key Applications: timing-critical high-end remote controls and point of sale (POS) scan guns and data terminals, I/O expansion tasks for space-limited systems (e.g., servers, storage, and communications), hardware acceleration for factory automation, image pre-processing, and displays (e.g., rotation and scaling), and bridging functions (e.g., video interfacing, processor glue logic, and image sensor bridges). |

iCEcube2Software Tool
iCEcube2 software is the design environment for the Lattice iCE40 family of ultra-low density FPGA devices. The updated iCEcube2 software includes improvements that increase accuracy. For example, the new version of iCEcube2 software now includes final timing and power data that enable design analysis under worst case as well as typical conditions. The updated data also reflect wider temperature ranges to support both commercial and industrial devices, which gives designers greater confidence that their design will operate correctly in a variety of conditions. The power estimator also has improved data and algorithms that increase the accuracy of dynamic and static power calculations.
iCEcube2 software for Windows Operating System can be downloaded from the Lattice website, and is fully enabled at no cost with the Lattice Diamond free license.
Lattice Diamond Programmer
Lattice Diamond Programmer offers an easy to use solution for programming all Lattice JTAG-based devices. Diamond Programmer is fully integrated into Diamond and is also available as a standalone application. FPGAs supported in Lattice Diamond, devices from ispLEVER Classic, PAC-Designers, and iCEcube2 are supported by Programmer when used in standalone mode. Diamond Programmer tool simplifies the most common steps, including setting up device information (cable, port etc); selecting the programming data file to use, and single project supports programming single or multiple devices.
