Lattice ICE40HX1K: An Overview of the Low-Power FPGA for Embedded Applications
The demand for flexible, low-power computing solutions in embedded systems has never been greater. From consumer electronics to industrial automation, designers seek hardware that offers both programmability and energy efficiency. The Lattice ICE40HX1K field-programmable gate array (FPGA) stands out as a pivotal solution in this space, combining a small form factor with remarkably low power consumption.
As part of Lattice Semiconductor’s iCE40 family, the HX1K is built on a mature low-power process technology. It features 1,280 lookup tables (LUTs) alongside embedded block RAM (EBR) and non-volatile configuration memory. This architecture allows the device to be instantly powered on without external boot memory, making it ideal for always-on or power-sensitive applications.
One of the most compelling features of the ICE40HX1K is its ultra-low power profile. With static power consumption as low as 21 µW and dynamic power scaling efficiently based on workload, this FPGA is suitable for battery-operated devices such as handheld instruments, IoT sensors, and wearable technology. Moreover, its support for multiple I/O standards, including LVCMOS, LVTTL, and I²C, enhances its interface versatility.
The device also supports a range of packaging options, such as QFN and TQFP, enabling compact PCB layouts. Coupled with Lattice’s development tools—like the free version of Lattice Radiant and iCEcube2—designers can rapidly prototype and deploy custom logic, DSP functions, or control paths even with limited resources.
Another notable advantage is the FPGA’s resilience in harsh environments. It operates reliably across industrial temperature ranges, making it a robust choice for automotive, medical, or outdoor applications.
