ICE5LP4K-UWG20ITR

The ICE5LP4K-UWG20ITR is an iCE40 Ultra™ family field-programmable gate array (FPGA) in a 20‑UFBGA WLCSP package. It combines a compact, surface-mount form factor with integrated logic, embedded memory, on-chip peripherals and hardened serial interfaces for space-constrained, low-power designs.

Targeted use cases include mobile and handheld devices, sensor management and always-on applications. The device emphasizes integration and ultra-low power operation through a 40 nm low-power process and on-chip support blocks that reduce external component count.

Key Features

• Core Logic — 3,520 logic elements for custom logic implementation and control tasks.
• Embedded Memory — 81,920 bits (approximately 80 kbits) of on-chip RAM for local data buffering and state storage.
• On‑chip DSP — DSP functional blocks supporting signed/unsigned 8‑bit and 16‑bit operations including multiplier, accumulator and MAC to offload simple preprocessing.
• Hardened Interfaces — Two on-chip SPI controllers and two on-chip I²C controllers for direct sensor and peripheral connectivity without soft‑IP overhead.
• Clocking — Two internal oscillators (10 kHz LFOSC and 48 MHz HFOSC), one PLL with dynamic interface and multiple global clock resources for flexible timing architectures.
• LED and IR Drivers — Three RGB PWM outputs with user-selectable sink up to 24 mA and one IR LED driver with up to 500 mA sink for direct LED/IR control.
• I/O and Packaging — 12 I/Os in a 20‑WLCSP (1.71 × 2.06 mm) surface-mount package for ultra-small board area; industrial grade mounting.
• Power — Nominal voltage supply range 1.14 V to 1.26 V to match low-voltage system rails.
• Operating Range — Industrial operating temperature from −40 °C to 100 °C.
• Compliance — RoHS compliant.

Typical Applications

• Smartphones and Mobile Devices — Sensor management, LED/IR control and small-footprint logic functions where low power and compact packaging are required.
• Tablets and Handheld Electronics — Local preprocessing, glue logic and interface bridging using on-chip SPI/I²C and DSP resources.
• Multi‑Sensor Systems — Aggregation and preprocessing for sensor fusion and always-on sensor tasks leveraging embedded memory and DSP blocks.
• USB Type‑C Cable Detect / Power Delivery — Compact logic and interface capability suitable for cable-detect and related control functions in constrained spaces.

Unique Advantages

• Highly Integrated Peripherals: Hardened SPI and I²C controllers, on-chip oscillators, DSP blocks and LED/IR drivers reduce external component count and simplify BOM.
• Ultra‑low Power Architecture: Built on a 40 nm low-power process with standby currents as low as 71 μA (typical), supporting energy-efficient always-on functions.
• Compact WLCSP Package: 20‑WLCSP (1.71 × 2.06 mm) surface-mount package minimizes PCB area for space-constrained designs.
• Embedded Memory and DSP: Approximately 80 kbits of on-chip RAM with DSP resources enables local buffering and preprocessing without external memory.
• Industrial Temperature Range: Rated for −40 °C to 100 °C, suitable for a wide range of commercial and industrial environments.
• Flexible Configuration: Device configuration via standard SPI or internal nonvolatile configuration memory (NVCM) supports multiple system architectures.
