ICE5LP4K-UWG20ITR1K

The ICE5LP4K-UWG20ITR1K is an iCE40 Ultra family field programmable gate array in a compact 20-WLCSP package. It provides 3520 logic elements and approximately 80 kbits of embedded memory in an ultra-small footprint tailored for low-power, sensor-driven and handheld applications.

Designed for industrial-grade use, this device integrates on-chip oscillators, hardened serial interfaces and dedicated I/O drivers while operating from a 1.14 V to 1.26 V supply across an industrial temperature range of -40 °C to 100 °C.

Key Features

• Logic Capacity — 3520 logic elements suitable for small to mid-density programmable logic tasks.
• Embedded Memory — Approximately 80 kbits of on-chip block RAM for buffering, state storage, and local data processing.
• I/O and Package — 12 user I/Os in a 20-WLCSP (1.71 × 2.06 mm) package for ultra-small form-factor designs and surface-mount assembly.
• Power — Core supply range 1.14 V to 1.26 V enabling low-voltage system integration.
• Operating Range — Industrial temperature grade, rated from -40 °C to 100 °C for deployment in commercial and industrial environments.
• On-Chip Clocks — Two on-chip oscillators (10 kHz LFOSC and 48 MHz HFOSC) for always-on and active-mode timing without external crystals.
• Hardened Serial Interfaces — Integrated SPI and I²C blocks for direct sensor and processor interfacing as part of system management functions.
• LED and IR Drivers — Three 24 mA RGB open-drain outputs and one 500 mA IR LED driver for direct LED/IR interfacing without external MOSFETs or buffers.
• On-Chip DSP — DSP block supporting signed/unsigned 8-bit and 16-bit multiply, accumulate, and multiply-accumulate functions to offload simple signal pre-processing.
• Configuration Options — SRAM configuration via standard SPI or internal nonvolatile configuration memory (NVCM) for flexible system boot strategies.
• Regulatory — RoHS compliant.

Typical Applications

• Always-On Sensor Management — Use the low-frequency oscillator and hardened I²C/SPI interfaces to aggregate and pre-process sensor data while preserving system power.
• Mobile and Handheld Devices — Compact WLCSP package and low-power operation make the device suitable for space-constrained, battery-powered products.
• Service LED and IR Control — Built-in RGB outputs and high-current IR driver enable direct control of indicator LEDs and IR emitters without external drivers.
• Sensor Pre‑processing and Fusion — On-chip DSP and embedded RAM allow local data filtering and simple fusion tasks before passing results to the application processor.

Unique Advantages

• Ultra-small footprint: 20-WLCSP (1.71 × 2.06 mm) package minimizes PCB area for compact designs.
• Integrated signal chain: Hardened SPI/I²C, oscillators, LED/IR drivers and DSP reduce external component count and BOM complexity.
• Low-voltage operation: 1.14 V–1.26 V core supply fits modern low-voltage system domains.
• Industrial temperature capability: Rated from -40 °C to 100 °C for reliable operation in commercial and industrial environments.
• Flexible configuration: SRAM programming via SPI or internal NVCM supports varied system boot and update strategies.
