ICE5LP1K-SG48ITR

The ICE5LP1K-SG48ITR is an iCE40 Ultra™ family FPGA from Lattice Semiconductor designed for ultra-low power, compact embedded applications. It provides 1,100 logic elements, 65,536 bits of embedded RAM and 39 programmable I/Os in a 48‑VFQFN exposed pad package.

As part of the iCE40 Ultra family, this device targets mobile and handheld sensor-management applications by combining low-power operation, integrated serial interfaces and on-chip peripherals such as oscillators, DSP blocks and LED drivers to simplify system design and reduce external components.

Key Features

• Core Logic 1,100 logic elements for implementing control, glue-logic and signal-processing functions in a compact FPGA.
• Embedded Memory 65,536 bits of on-chip RAM for buffering and local data storage.
• Programmable I/O 39 I/Os available for sensor interfaces, peripherals and control signals.
• On-chip Peripherals Family features include hardened SPI and I²C controllers, DSP functional blocks, RGB PWM outputs and a high-current IR LED driver to off-load host processing and drive LEDs directly.
• Clocking and Oscillators Two on-chip oscillators (10 kHz LFOSC and 48 MHz HFOSC) and flexible global clock resources to support both always-on and active modes.
• Power Core supply range: 1.14 V to 1.26 V, supporting ultra-low power operation as described for the iCE40 Ultra family.
• Package & Mounting 48‑VFQFN exposed pad (48‑QFN, 7 × 7 mm) surface-mount package with exposed pad for thermal connection.
• Temperature & Grade Industrial-grade device rated for operation from −40 °C to 100 °C. RoHS compliant.

Typical Applications

• Smartphones and Mobile Devices Sensor interfacing, low-power always-on tasks and LED/IR control in compact mobile designs.
• Tablets and Handheld Devices On-device pre-processing, I/O expansion and custom logic functions where small form factor and low power are important.
• Multi-Sensor Management Aggregation, pre-processing and protocol bridging for multiple sensors using integrated SPI/I²C controllers and DSP blocks.
• Always-On Sensor Applications Low-frequency oscillator and low standby current in the family support always-on monitoring and wake-up logic.
• USB Type-C Cable Detect / Power Delivery Signal conditioning and state-machine implementation for cable detect and related functions.

Unique Advantages

• Highly integrated peripheral set: Hardened SPI and I²C controllers, DSP blocks and LED/IR drivers reduce external component count and simplify BOM.
• Ultra-low power family architecture: On-chip LFOSC and HFOSC plus low standby currents enable always-on and intermittent sensing use cases with minimized power draw.
• Compact, thermally aware packaging: 48‑VFQFN with exposed pad supports small board area while allowing thermal management through the exposed pad.
• Industrial temperature range: Rated from −40 °C to 100 °C for reliable operation in a wide set of commercial and industrial environments.
• Flexible clocking and DSP: Multiple clock resources and on-chip DSP blocks allow local signal processing and timing control without relying on the application processor.
• RoHS compliant: Meets applicable lead-free and environmental requirements for modern manufacturing.
