ICE40UL1K-SWG16ITR

The ICE40UL1K-SWG16ITR is an iCE40 UltraLite™ FPGA from Lattice Semiconductor Corporation, offered in a compact 16-ball WLCSP package. It combines approximately 1,248 logic elements and on-chip embedded memory with integrated peripherals to address ultra-low-power mobile and handheld applications as well as industrial handheld devices.

This device is optimized for small-footprint designs that require low standby current, integrated LED and IR driver functions, and simple sensor-management or I/O expansion tasks. Its industrial temperature rating and narrow supply range make it suitable for designs that demand predictable electrical and thermal behavior.

Key Features

• Logic Capacity — 1,248 logic elements for implementing glue logic, simple controllers, or sensor-management functions.
• Embedded Memory — 57,344 bits of on-chip RAM (approximately 56 kbits) to store configuration data, buffers, or small lookup tables.
• On-chip Oscillators — Two internal oscillators (10 kHz LFOSC and 48 MHz HFOSC) for ultra-low-power always-on functions and higher-speed wake activities.
• Hardened LED and IR Peripherals — Integrated RGB PWM and hardened TX/RX pulse logic for IR and barcode-emulation drivers, with dedicated current-drive outputs described in the family datasheet.
• Interfaces — Support for optional FIFO-mode I²C up to 1 MHz and programmable I/Os (10 user I/O pins) for sensor and processor interfacing.
• Clocking and Timing — Multiple low-skew global signals and a PLL with dynamic interface to support synchronized on-chip logic.
• Power and Package — Ultra-low-power 40 nm process with typical low standby current; operates from a 1.14 V to 1.26 V supply and is available in a 16-ball WLCSP (1.4 × 1.48 mm) surface-mount package.
• Industrial Temperature Range — Qualified for operation from −40 °C to 100 °C for use in temperature-challenging environments.

Typical Applications

• Smartphones and Mobile Devices — Low-power sensor management, LED control and simple protocol bridging using the internal oscillators and small logic fabric.
• Handheld Industrial Devices — Compact, industrial-temperature FPGA for GPIO expansion, simple data buffering, and interface adaptation in tight PCB space.
• IR Remote and Barcode Emulation — Use the hardened TX/RX pulse logic and dedicated IR/barcode driver outputs to implement IR or barcode-emulation functions directly.
• RGB and LED Control — Integrated RGB PWM and constant-current LED outputs simplify LED driver designs without external MOSFETs or buffers.

Unique Advantages

• Compact WLCSP Footprint: Minimizes PCB area with a 16-ball WLCSP (1.4 × 1.48 mm), enabling ultra-small product designs.
• Integrated LED/IR Drivers: Hardened PWM and TX/RX logic with dedicated current-drive outputs reduce BOM and external component count for LED and IR functions.
• Low-Power Operation: Built on a 40 nm low-power process with family-level standby current optimizations, supporting always-on and intermittently active designs.
• Industrial Reliability: Specified for −40 °C to 100 °C operation, making it suitable for temperature-demanding handheld and industrial applications.
• Flexible Configuration: Multiple configuration options and programmable I/Os allow quick adaptation to a variety of sensor and interface roles.
