Overview

The iCE5LP1K-SG48ITR is a member of the iCE40 Ultra family, designed specifically for power-sensitive mobile and wearable applications. It provides 1100 logic cells and 80 KB of RAM in a compact 48-VFQFN package, operating on a low 1.2V core voltage. This FPGA includes dedicated IP for RGB PWM control and DSP blocks to offload computationally intensive tasks from a primary microcontroller.

Why Choose This Part

This device features a remarkably low standby current of 71 uA and includes dedicated DSP functional blocks for hardware acceleration in a tiny footprint. It simplifies system design by integrating an internal oscillator and fixed I2C/SPI hard IP cores, reducing the logic cell overhead typically required for standard serial interfaces.

Applications

Always-on Sensor Buffering
Uses the 80 KB of embedded RAM to buffer sensor data while the main application processor remains in deep sleep.
LED Management
Utilizes the built-in RGB PWM IP to drive notification LEDs and breath-lighting effects without CPU intervention.
Smartphone Peripheral Offloading
Handles hardware-accelerated tasks like IR remote control modulation, barometric pressure calculations, or pedometer logic.
