Overview

The ICE40HX1K-VQ100 is a high-performance, low-density FPGA from Lattice Semiconductor designed for high-speed logic applications. Part of the iCE40 HX series, it offers 1280 logic cells and 72 user I/Os in a standard 100-VQFP package, making it an accessible choice for glue-logic and interface bridging. This device is optimized for low power consumption with a sleep current of approximately 296 uA.

Why Choose This Part

This FPGA offers a balance of 1280 logic cells and 65536 bits of RAM in a package that is relatively easy to solder for prototyping. It supports industrial temperature ranges from -40C up to 100C, providing reliability in harsh environments while maintaining low power consumption. The device is compatible with open-source toolchains, significantly reducing software costs and vendor lock-in.

Applications

Interface Bridging
Connecting incompatible logic levels or protocols between a host processor and peripherals using the 72 available I/O pins.
Hardware Acceleration
Offloading timing-critical tasks such as PWM generation or custom serial protocols from a primary microcontroller.
Sensor Data Aggregation
Using the 64Kb of internal RAM to buffer data from multiple low-speed I2C or SPI sensors before burst-transmitting to a host.
Glue Logic
Replacing multiple discrete 74-series logic chips to reduce PCB footprint and complexity in industrial control systems.

Getting Started

To begin development, engineers can use the Lattice iCEcube2 software or the popular open-source IceStorm toolchain for synthesis and routing. Hardware development is often performed using the iCE40HX1K-B-EVN evaluation board, which allows for direct programming via SPI. Ensure a stable 1.2V core power supply is provided as per the 1.14V to 1.26V specification.
