Overview of ICE40LM4K-SWG25TR – Ultra-low Power 25‑WLCSP FPGA

The ICE40LM4K-SWG25TR is an ultra-low power Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation. Built on a 40 nm low-power process, this device provides 3,520 logic elements with integrated memory and hardened peripheral controllers in an ultra-small 25‑ball WLCSP (1.71 mm × 1.71 mm) package. It is optimized for space-constrained, always‑on and mobile sensor-management applications requiring low standby power and flexible I/O.

Key Features

  • Core Logic  Provides 3,520 logic elements (LUTs) organized across 440 CLBs for compact programmable logic implementations.
  • Embedded Memory  Approximately 80 kbits of embedded block RAM (81,920 bits) for local buffering, state, and small-data processing.
  • Low-Power Operation  Designed on an advanced 40 nm ultra-low power process with standby power as low as 120 μW (typical), suitable for always-on sensor tasks.
  • Interfaces  Two hardened I2C controllers and two hardened SPI controllers are included; programmable I/Os can be used as either these interfaces or general-purpose I/Os. The device provides 18 I/O pins in the 25‑pin WLCSP.
  • Strobe Generators  Includes two on-chip strobe generators: a Low‑Power Strobe Generator (microsecond range) and a High‑Speed Strobe Generator (nanosecond range) for timing-sensitive sensor and peripheral control.
  • High-Drive Outputs  Three High Drive outputs are provided with nominal source/sink capability of 24 mA for direct LED drive or other high-current signaling needs.
  • Clocking and Routing  Six low-skew global signal resources support predictable clock distribution and low-skew routing for timing-critical paths.
  • Flexible Configuration  SRAM-based configuration is loaded via SPI, enabling flexible in-system programming and updates.
  • Package and Mounting  25‑WLCSP (1.7 mm × 1.7 mm) surface-mount package (25‑XFBGA/WLCSP) for ultra-small form-factor designs.
  • Industrial Grade  Rated for operation from −40 °C to 100 °C and a supply voltage range of 1.14 V to 1.26 V.
  • Compliance  RoHS compliant.

Typical Applications

  • Always-On Sensor Management  Act as a low-power sensor manager or pre-processor, handling I2C/SPI sensor interfaces and local event detection while minimizing standby power.
  • Mobile and Handheld Devices  Implement compact control logic, interface bridges, or user-interface handlers in space-constrained smartphones, tablets, and handheld devices.
  • Multi-Sensor Fusion  Provide local aggregation, timing, and pre-processing of multiple sensors using embedded RAM and on-chip strobe generators for synchronized sampling.
  • LED and Indicator Drivers  Drive status LEDs or indicators directly using the device’s high-drive outputs while keeping system-level logic compact and power-efficient.

Unique Advantages

  • Ultra-Small Footprint: The 25‑WLCSP (1.71 mm × 1.71 mm) package enables integration into tight board spaces where discrete logic would be difficult to place.
  • Low Standby Power: Standby power as low as 120 μW (typical) reduces overall system power for always-on and battery-powered applications.
  • Integrated Sensor Interfaces: Hardened I2C and SPI controllers with programmable I/Os reduce external component count and simplify sensor interfacing.
  • Deterministic Timing Support: On-chip strobe generators and six low-skew global signal resources help deliver precise timing for sensor sampling and control signals.
  • Industrial Temperature Range: Rated from −40 °C to 100 °C to support commercial and industrial applications requiring extended operating temperature.
  • Compact Embedded Memory: Approximately 80 kbits of block RAM supports local buffering and small-state machines without external memory.

Why Choose ICE40LM4K-SWG25TR?

The ICE40LM4K-SWG25TR combines a high-density programmable fabric (3,520 logic elements) with embedded RAM, hardened I2C/SPI controllers, strobe generators and high-drive outputs in an ultra-small 25‑WLCSP package. Its low-voltage operation (1.14 V to 1.26 V), ultra-low standby power and industrial temperature rating make it well suited for compact, low-power sensor-manager and always-on roles in portable and industrial designs.

Designed and supported by Lattice Semiconductor Corporation, this device targets developers who need a compact, integrated FPGA solution that reduces BOM, saves board space, and provides flexibility for in-field updates through SPI configuration.
