LSCCICE40UP5K-SG48I
Overview
The ICE40UP5K-SG48I is an ultra-low power FPGA from Lattice Semiconductor's iCE40 UltraPlus family, providing 5280 logic cells and 1024 KB of RAM. Designed for mobile and power-constrained applications, it features hardened I2C and SPI interfaces along with on-chip DSP blocks to offload compute-intensive tasks from a host processor. Its 48-QFN package and 100 microamp standby current make it ideal for always-on sensing and edge processing.
Why Choose This Part
The iCE40UP5K stands out for its high density of embedded RAM (1171456 bits) relative to its physical size, allowing for significant data buffering without external memory. It features hardened IP for common serial protocols and integrated oscillators, which simplifies PCB design and reduces total system power consumption compared to software-emulated solutions.
Applications
Key Specifications
Getting Started
Designers should use the Lattice Radiant software for synthesis, placement, and routing. For hardware evaluation, the iCE40 UltraPlus Breakout Board allows for rapid prototyping of the 48-QFN package. Open-source toolchains like Project IceStorm also provide an alternative flow for synthesis and bitstream generation.
