ICE5LP4K-CM36ITR

The ICE5LP4K-CM36ITR is an iCE40 Ultra field programmable gate array (FPGA) in a compact 36‑VFBGA package. It delivers 3,520 logic elements, approximately 80 kbits of embedded RAM, and a suite of on‑chip peripherals intended for ultra‑low power mobile and handheld sensor management applications.

Designed for space‑constrained, industrial‑grade designs, the device integrates hardened SPI and I²C controllers, on‑chip oscillators, DSP resources and LED/IR drivers to reduce external components and simplify system design.

Key Features

• Core Logic — 3,520 logic elements for implementing combinational and sequential logic, plus flexible routing resources suitable for sensor interfacing and control logic.
• Embedded Memory — Approximately 80 kbits (81,920 bits) of on‑chip RAM for buffering, small data structures and local state storage.
• On‑Chip DSP — Integrated DSP functional blocks for signed/unsigned 8‑bit and 16‑bit operations including multiplier, accumulator and MAC functions to off‑load processor tasks.
• Hardened Serial Interfaces — Two SPI controllers and two I²C controllers for direct connection to sensors and peripherals without implementing those protocols in fabric.
• Oscillators & Clocking — Two on‑chip oscillators (10 kHz LFOSC and 48 MHz HFOSC) for always‑on and active operation, plus flexible global clock resources and a PLL for clock management.
• LED & IR Drivers — Three 24 mA RGB PWM outputs for service LEDs and a 500 mA IR LED driver for direct IR LED interfacing or barcode emulation.
• I/O and Package — 26 user I/Os in a 36‑UCFBGA (2.5 × 2.5 mm) surface‑mount package, enabling compact board placement and direct peripheral connectivity.
• Power and Temperature — Low supply voltage range of 1.14 V to 1.26 V and industrial operating temperature range from −40 °C to 100 °C for robust performance in harsh environments.
• Configuration Options — Supports standard SPI configuration and internal nonvolatile configuration memory (NVCM) for flexible device provisioning.
• Low Power — Family‑level ultra‑low power characteristics (family data shows standby currents as low as typical 71 μA), suitable for always‑on sensor and mobile applications.

Typical Applications

• Smartphones and Tablets — Acts as a sensor manager or peripheral interface, using hardened I²C/SPI and low‑power oscillators to handle always‑on sensor tasks.
• Handheld Commercial and Industrial Devices — Implements user interfaces, LED control and peripheral glue logic in a compact, industrial‑rated package.
• Multi‑Sensor Management — Aggregates and pre‑processes sensor data using on‑chip DSP blocks and embedded RAM for sensor fusion and preprocessing.
• Always‑On and Low‑Power Systems — Uses the LFOSC and low standby currents to maintain wake/sleep control and background monitoring with minimal power draw.
• IR and LED Driven Functions — Directly drives service RGB LEDs and high‑current IR LEDs for IR communication or barcode emulation without external MOSFETs.

Unique Advantages

• Highly integrated peripherals: Hardened SPI/I²C, oscillators, LED/IR drivers and DSP blocks reduce external components and simplify PCB designs.
• Compact, production‑ready package: 36‑UCFBGA (2.5 × 2.5 mm) surface‑mount footprint helps conserve board area in portable and space‑constrained products.
• Low voltage, low power operation: 1.14 V–1.26 V supply range and family‑level low standby current enable battery‑sensitive designs and always‑on features.
• Industrial temperature rating: −40 °C to 100 °C operating range supports commercial and industrial deployments in challenging environments.
• On‑chip processing: Embedded DSP and block RAM allow local preprocessing and off‑loading of tasks that would otherwise consume host CPU resources.
