Overview

The iCE40UL1K-CM36AI is an ultra-low power iCE40 UltraLite FPGA designed for mobile and wearable applications where power and space are at a premium. It features 1248 logic cells, 56 Kbits of embedded RAM, and specialized hardened IP for driving IR and RGB LEDs. This device is optimized for always-on functions, providing a flexible alternative to microcontrollers in a compact 2.5mm x 2.5mm 36-UCBGA package.

Why Choose This Part

The iCE40UL1K integrates unique hardware blocks for LEDs and IR logic that typically require external transistors, reducing the overall BOM and PCB footprint. Its extremely low power profile, with a core run current of approximately 3.06mA, makes it suitable for battery-operated devices that require custom logic flexibility.

Applications

RGB LED Control
Utilizes three hardened PWM channels and 24 mA current sinks to drive notification LEDs without taxing the application processor.
Infrared Remote Control
Features a dedicated TX/RX pulse logic circuit for IR LED communication with high-current drive support up to 500 mA.
Barcode Emulation
Includes a specialized 100 mA current drive output specifically for barcode emulator applications in handheld devices.
Always-On Sensor Hub
Acts as a low-power intermediary for processing sensor data via I2C and SPI interfaces while consuming as little as 35 uA standby current.

Getting Started

Designers can use the Lattice iCEcube2 or Radiant software for synthesis and place-and-route. Hardware development is often performed using the iCE40 UltraLite Breakout Board, which allows for testing the NVCM programming and the 26 available I/Os. The device supports configuration via SPI or the internal Nonvolatile Configuration Memory for single-chip operation.
