ICE5LP4K-UWG20ITR50

The ICE5LP4K-UWG20ITR50 is an iCE40 Ultra™ family field-programmable gate array designed for ultra-low-power mobile and sensor-management applications. It provides a compact, highly integrated FPGA fabric with 3520 logic elements and approximately 81.92 kbits of embedded RAM to implement control, pre-processing and interfacing functions in space-constrained designs.

This device integrates hardened interfaces, on-chip oscillators, DSP resources and high-current LED/IR drivers, delivering a platform for always-on and sensor-focused applications while supporting industrial temperature operation and low-voltage supply rails.

Key Features

• Core Logic  3520 logic elements (LUT-based fabric) suitable for control, glue-logic and small to medium user-defined functions.
• Embedded Memory  Approximately 81.92 kbits of on-chip RAM for state, buffers and working data for user logic.
• Interfaces  Two hardened SPI controllers and two hardened I²C controllers are available for direct sensor and peripheral interfacing; 12 user I/Os provide flexible connectivity options.
• On-chip Peripherals  Includes on-chip DSP blocks for signed/unsigned 8-bit or 16-bit multiply, accumulate and MAC operations to off-load application processors.
• LED and IR Drivers  Three 24 mA RGB current-drive outputs plus one 500 mA IR LED open-drain driver for direct LED/IR interfacing and modulation use cases.
• Clocking  Dual internal oscillators (10 kHz LFOSC and 48 MHz HFOSC) plus a PLL and multiple low-skew global clock resources for flexible timing and always-on/awake modes.
• Power and Supply  Operates from a low-voltage supply between 1.14 V and 1.26 V, supporting ultra-low-power system designs.
• Package and Mounting  20-WLCSP (1.71 × 2.06 mm) wafer-level CSP / 20-UFBGA WLCSP package intended for surface-mount applications needing minimal PCB area.
• Temperature and Reliability  Industrial-grade operation across −40 °C to 100 °C; RoHS compliant.

Typical Applications

• Mobile and Handheld Devices  Sensor management, low-power control and simple signal processing tasks in smartphones, tablets and portable electronics.
• Always‑On Sensor Systems  Low-frequency oscillator and low-standby power characteristics enable always-on sensor supervision and wake-up logic.
• Embedded Sensor Pre-processing  On-chip DSP and embedded RAM handle preprocessing and sensor fusion tasks to reduce host processor load.
• LED and IR Interfaces  Integrated RGB LED drivers and a high-current IR driver simplify direct LED/IR modulation and signaling without external buffering.
• Compact Industrial Controls  Small WLCSP package and industrial temperature range suit space-constrained commercial and industrial handheld devices.

Unique Advantages

• Highly integrated I/O and peripherals: Hardened SPI and I²C controllers, oscillators and LED/IR drivers reduce external component count and simplify board design.
• On-chip DSP acceleration: DSP blocks enable local preprocessing and MAC operations, lowering system CPU load and improving responsiveness.
• Compact footprint: 20-WLCSP package with surface-mount mounting minimizes PCB area for dense or portable product designs.
• Low-voltage operation: Narrow supply range (1.14–1.26 V) targets ultra-low-power system architectures and tight power budgets.
• Industrial temperature support: Rated for −40 °C to 100 °C to meet the environmental demands of commercial and industrial deployments.
• Embedded memory for on‑chip buffering: Approximately 81.92 kbits of RAM enables local data storage and state retention without external RAM.
