iCE40UP5K-SG48I
5,280-cell Lattice iCE40 UltraPlus FPGA in QFN-48 with 1 Mb SPRAM and eight multipliers for always-on sensing and mobile designs.
The iCE40UP5K-SG48I is a Lattice iCE40 UltraPlus FPGA with 5,280 logic cells, 1 Mb of SPRAM, 120 Kb of block RAM and eight DSP multipliers in a 48-pin QFN package. The UltraPlus family extends the power-optimized iCE40 architecture with the embedded memory and multiplier resources needed for always-on sensor and audio pre-processing, so a small, low-cost FPGA can handle functions that would otherwise wake a power-hungry applications processor. The device configures instantly from on-chip non-volatile memory and supports low-power standby modes, which suits battery-powered and energy-harvesting products where every milliwatt counts. Typical uses include sensor fusion and hub modules, gesture and voice wake detection, camera and display control, and simple glue logic that must remain live while the rest of the system sleeps. The QFN-48 package is easy to place and route and keeps the board small, and the fabric is supported by both Lattice's toolchain and open-source synthesis flows. The iCE40 architecture is well understood and quick to bring up, which shortens development for high-volume consumer and mobile products. Every device is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. BeiLuo holds this class in stock and our FAE team supports power planning, configuration and I/O.
FAE Professional Review
The iCE40UP5K-SG48I is the part we recommend when an always-on function must run on microwatts. The 5K cells plus 1 Mb SPRAM and eight multipliers handle sensor fusion and audio pre-processing without waking the main processor. Design the power modes carefully and it is remarkably frugal.

Frequently Asked Questions
What projects suit the iCE40UP5K-SG48I?
It fits always-on functions in battery-powered products such as sensor hubs, gesture and voice wake detection, and display or camera control, where the main processor should stay asleep. The SPRAM and multipliers handle buffering and light DSP.
For more logic, step up to ECP5 or Certus-NX.
How do I keep iCE40 power low?
Separate the always-on function from burst processing, use the low-power standby mode, clock only what you need, and choose the configuration scheme for instant wake. Measure standby current on your board before committing.
