ICE40UL640-SWG16ITR1K

The ICE40UL640-SWG16ITR1K is an ultra-small, ultra-low-power FPGA based on the iCE40 UltraLite family architecture. It provides 640 logic elements, approximately 57,344 bits of on-chip RAM, and a compact 16-ball WLCSP (1.4 × 1.48 mm) package for space-constrained, industrial-temperature designs.

Designed for applications that require instant-on operation, tight power budgets and integrated sensor/LED/IR management, this device combines a low-voltage supply range (1.14 V to 1.26 V) and industrial operating temperature (-40 °C to 100 °C) for robust embedded implementations.

Key Features

• Logic 640 logic elements for compact programmable logic implementations.
• Embedded Memory 57,344 bits of on-chip RAM to support configuration and user logic data storage.
• I/O and Interfaces 10 general-purpose I/Os suitable for small interface counts and sensor ports; family-level support includes optional I²C FIFO-mode interfaces.
• Power and Clocking Low-voltage operation from 1.14 V to 1.26 V and family-level on-chip oscillators (10 kHz LFOSC and 48 MHz HFOSC) for always-on and active timing needs.
• Hardened LED and IR Support Family features include hardened RGB PWM, a hardened TX/RX pulse logic for IR, a 400 mA IR driver output, and a 100 mA barcode emulator driver to simplify LED/IR implementations.
• Package and Mounting 16-ball WLCSP (1.4 × 1.48 mm) supplier device package; surface-mount mounting for minimal PCB footprint.
• Industrial Temperature Rated for operation from -40 °C to 100 °C, suitable for industrial environments.
• Regulatory RoHS compliant.

Typical Applications

• Sensor Management Compact, low-power sensor hubs and multi-sensor interfaces that benefit from on-chip oscillators and small form factor packaging.
• Mobile and Handheld Devices Instant-on, low-standby-power logic for handheld displays, control interfaces and peripheral bridging in space-constrained designs.
• IR Remote and Barcode Emulation Direct drive and pulse logic for IR transmit/receive and barcode-emulation functions using the device’s hardened drivers.
• RGB and Indicator LED Control Integrated RGB PWM and current-drive outputs for status, illumination and user-interface LEDs without external MOSFETs or buffers.

Unique Advantages

• Ultra-small footprint: 16-WLCSP (1.4 × 1.48 mm) package minimizes PCB area for compact systems.
• Low-voltage, low-power operation: Narrow supply range (1.14–1.26 V) and family-level standby current metrics support energy-conscious designs.
• Integrated LED/IR peripherals: Hardened PWM and IR/barcode driver capabilities reduce BOM and simplify board design.
• Industrial temperature range: -40 °C to 100 °C rating enables deployment in industrial and harsh environments.
• On-chip memory for compact logic: 57,344 bits of embedded RAM allows local data buffering and logic state storage without external memory.
