ICE5LP1K-UWG20ITR

The ICE5LP1K-UWG20ITR is an iCE40 Ultra family field-programmable gate array in a 20‑WLCSP (1.71 × 2.06 mm) package. It delivers approximately 1100 logic elements with embedded memory and a compact surface-mount footprint aimed at low-power mobile and sensor-management applications.

Designed for ultra-low power integration, the device combines programmable logic with hardened interfaces, on-chip oscillators and DSP resources to support functions such as sensor pre-processing, LED/IR drivers, and general-purpose I/O expansion in space-constrained, industrial-temperature designs.

Key Features

• Core Logic — Approximately 1100 logic elements suitable for small to medium control, glue-logic and sensor-management functions.
• Embedded Memory — 65,536 bits of on-chip RAM (approximately 64 kbits) to store configuration and user data for real-time processing.
• On-chip Peripherals — Family-level features include two hardened I²C controllers, two hardened SPI controllers, two on-chip oscillators (10 kHz LFOSC and 48 MHz HFOSC) and on-chip DSP blocks for 8‑ or 16‑bit signed/unsigned math operations.
• LED and IR Drive — Family supports three 24 mA RGB PWM outputs and one 500 mA IR LED driver (family datasheet feature) for direct LED interfacing and IR modulation tasks.
• I/O and Packaging — 12 user I/Os available; supplied in a 20‑UFBGA WLCSP package (20‑WLCSP, 1.71 × 2.06 mm) with surface-mount mounting for compact board designs.
• Power — Core voltage supply range of 1.14 V to 1.26 V for low-voltage system integration.
• Temperature and Grade — Industrial grade with an operating temperature range of −40 °C to 100 °C for use in demanding environments.

Typical Applications

• Mobile and Handheld Devices — Always‑on sensor management, low-power wake/sleep control and sensor pre-processing in smartphones, tablets and portable consumer electronics.
• Multi-Sensor Systems — Sensor fusion and preprocessing where on‑chip DSP and embedded memory reduce workload for a host processor.
• LED and IR Interfaces — Service RGB LED control and direct IR LED driving for status indicators, remote‑control or barcode‑emulation functions.
• USB Type-C and Power Detection — Logic and signal conditioning for cable-detect/power-delivery related functions in compact designs.

Unique Advantages

• Ultra-low power profile: Family-level standby currents as low as typical µA levels support always‑on and battery‑sensitive applications.
• Highly integrated peripherals: Hardened I²C and SPI controllers plus on-chip oscillators and DSP blocks reduce external component count and simplify firmware.
• Direct LED/IR drive: Dedicated RGB and IR driver capabilities enable direct interfacing to LEDs without external MOSFETs or buffers (family-level features).
• Compact WLCSP package: 20‑WLCSP (1.71 × 2.06 mm) surface-mount footprint minimizes PCB area for space-constrained products.
• Industrial temperature rating: −40 °C to 100 °C operation supports deployment in industrial and harsh-environment applications.
• On-chip DSP acceleration: Embedded DSP resources accelerate common multi-byte math operations such as multiply and accumulate to off-load host processors.
