ICE5LP4K-SWG36ITR

The ICE5LP4K-SWG36ITR is an iCE40 Ultra™ ultra-low power field programmable gate array (FPGA) in a compact 36-WLCSP (2.1×2.1 mm) package. Built for mobile and always-on sensor applications, the device combines programmable logic with embedded memory, hardened serial interfaces and on-chip peripherals to simplify sensor management and low-power system designs.

With 3,520 logic elements, approximately 80 kbits of embedded RAM, 26 I/Os and an industrial temperature range, this FPGA targets handheld, mobile and industrial handheld applications where integration, low standby current and a small footprint matter.

Key Features

• Logic Capacity — 3,520 logic elements suitable for sensor pre-processing, glue logic and small to mid-size control functions.
• Embedded Memory — Approximately 80 kbits (81,920 bits) of on-chip RAM for buffering, state storage and small data structures.
• Peripherals & Interfaces — Two hardened I²C controllers and two hardened SPI controllers provide direct sensor and host interfaces without needing external cores.
• On‑Chip Oscillators — LFOSC (10 kHz) for low-power always‑on tasks and HFOSC (48 MHz) for active processing and wake events.
• DSP and Arithmetic — On-chip DSP block supporting signed/unsigned 8-bit and 16-bit operations including multiplier, accumulator and MAC functions to off-load application processors.
• LED and IR Drivers — Three 24 mA RGB LED outputs with selectable sink current and a dedicated 500 mA IR LED driver for direct LED interfacing and IR applications.
• Clocking & PLL — Flexible on-chip clocking with multiple low-skew global signal resources and one PLL with dynamic interface.
• Configuration Options — SRAM configuration via standard SPI or internal nonvolatile configuration memory (NVCM) for flexible field programming.
• Power and Operating Range — Supply voltage range 1.14 V to 1.26 V and industrial operating temperature range of −40 °C to 100 °C.
• Package and Size — 36-WLCSP (2.1×2.1 mm) supplier device package; family devices available in ultra-small form factors (as small as 2.078×2.078 mm).

Typical Applications

• Smartphones and Mobile Devices — Sensor management, LED/IR control and low-power preprocessing using the device’s SPI/I²C interfaces and DSP blocks.
• Always‑On Sensor Systems — Low-frequency oscillator and very low standby current enable ultra-low power monitoring and wake-on-event functions.
• Handheld Commercial & Industrial Devices — Compact WLCSP package, industrial temperature rating and integrated interfaces make it suitable for portable industrial tools and handheld controllers.
• Sensor Pre‑processing & Fusion — On-chip DSP and embedded RAM allow local preprocessing of sensor data before passing to host processors, reducing system-level bandwidth and power.
• USB Type‑C Cable Detect / Power Delivery — Flexible I/O and programmable logic can be used to implement cable-detect and control functions in compact designs.

Unique Advantages

• Highly integrated peripherals: Hardened SPI and I²C, on-chip oscillators, DSP, LED and IR drivers reduce external component count and simplify PCB designs.
• Ultra‑low power architecture: Designed for low standby current and with a 10 kHz LFOSC for always‑on tasks, enabling energy-efficient sensor and mobile applications.
• Compact footprint: 36‑WLCSP (2.1×2.1 mm) package and family options in ultra-small form factors help minimize board area in space-constrained products.
• Deterministic on‑chip resources: Multiple global clock resources and a PLL provide flexible, low-skew clocking for timing-critical interfaces and logic.
• Embedded DSP and RAM: Built-in MAC/DSP blocks and ~80 kbits of RAM let designers off-load compute tasks and store intermediate data without external memory.
