Overview

The iCE40UP5K-SG48 is an ultra-low power FPGA from the iCE40 UltraPlus family, designed for high-performance mobile and edge applications. It features 5280 Look-Up Tables (LUTs) and 120 kb of RAM in a compact 48-pin QFN package, making it suitable for hardware acceleration and interface bridging in space-constrained designs. The device includes hardened I2C and SPI IPs along with specialized DSP blocks to offload complex computations from a host processor.

Why Choose This Part

The iCE40UP5K offers an exceptional balance of low power consumption, with a standby current of only 100 uA, and high logic density. It simplifies system design by integrating internal non-volatile configuration memory (NVCM) and a built-in oscillator, reducing the need for external components. The 0.5 mm pitch QFN package provides a robust and accessible physical footprint compared to BGA alternatives while maintaining a small 7x7 mm size.

Applications

Edge AI and Image Processing
Utilizes on-chip DSP blocks to perform low-power machine learning inference and signal processing at the edge.
RGB LED Control
Uses three dedicated 24 mA current-sink outputs to drive RGB LEDs directly for status indicators or notification lighting.
Sensor Hub Aggregation
Leverages hardened I2C and SPI interfaces to manage multiple sensors while the main application processor remains in sleep mode.
Interface Bridging
Acts as a flexible bridge between disparate protocols like I3C, SPI, and UART in mobile or wearable devices.

Getting Started

Designers can use the Lattice Radiant software for synthesis, placement, and routing. For open-source workflows, the iCE40 family is well-supported by the IceStorm (Yosys/nextpnr) toolchain. Evaluation can be performed using the iCE40 UltraPlus Breakout Board or the iCE40UP5K-MDP-EVN Mobile Development Platform.
