ICE40UL640-SWG16ITR

The ICE40UL640-SWG16ITR is a member of the iCE40 UltraLite™ family of ultra‑low power Field Programmable Gate Arrays (FPGAs). It provides 640 logic elements with approximately 57,344 bits of embedded RAM and integrated peripherals targeted at compact, power‑sensitive designs.

Designed for small form‑factor mobile and sensor‑management applications, this industrial‑grade device combines low standby power, on‑chip oscillators and hardened LED/IR interfaces in a 16‑ball WLCSP package for space‑constrained systems.

Key Features

• Core Logic  640 logic elements (LUTs) suitable for glue logic, I/O expansion and lightweight control functions.
• Embedded Memory  Approximately 57,344 bits of on‑chip RAM to support user logic and buffering needs.
• Integrated Peripherals  Hardened RGB PWM, TX/RX pulse logic for IR LED, and barcode emulator driver functions are included in the family to simplify LED/IR interfaces.
• On‑Chip Oscillators  Two internal oscillators: a 10 kHz LFOSC for low‑power always‑on tasks and a 48 MHz HFOSC for higher activity periods.
• Clocking  Multiple low‑skew global resources and one PLL with dynamic interface to support flexible clock distribution.
• Interfaces  Up to 10 general purpose I/O pins and optional two‑channel FIFO‑mode I²C interface (up to 1 MHz, master or slave).
• Power  Operates from a 1.14 V to 1.26 V supply; typical standby current of 35 μA (≈42 μW standby power) for ultra‑low power applications.
• Package & Mounting  16‑ball WLCSP (1.4 × 1.48 mm) surface‑mount package for minimal PCB footprint.
• Temperature & Reliability  Industrial operating temperature range from −40 °C to 100 °C; RoHS compliant.

Typical Applications

• Mobile and Handheld Devices  Always‑on sensor management, status LED control and lightweight protocol bridging in smartphones, tablets and portable products.
• Multi‑Sensor Management  Aggregate sensor signals, perform simple preprocessing and present a compact interface to host processors in multi‑sensor systems.
• IR Remote and Barcode Emulation  On‑chip IR TX/RX pulse logic and high‑current IR/barcode drivers enable direct LED interfacing for remote control and barcode emulator applications.
• User Interface and RGB Lighting  Hardened RGB PWM and current‑drive outputs simplify service LED and RGB control without external driver ICs.
• Handheld Industrial Devices  Small footprint and industrial temperature rating make it suitable for compact, field‑deployed handheld instruments.

Unique Advantages

• Ultra‑Low Power Standby  Typical 35 μA standby current (≈42 μW) minimizes battery drain for always‑on functions.
• Compact Package  16‑ball WLCSP (1.4 × 1.48 mm) delivers a very small PCB footprint for tight space budgets.
• Integrated LED/IR Drivers  Hardened RGB PWM and IR/barcode drivers reduce external component count and simplify board design.
• Flexible Configuration  Supports standard SPI configuration and internal nonvolatile configuration memory (NVCM) for flexible device provisioning.
• Industrial Temperature Range  Rated for −40 °C to 100 °C operation to meet a range of field and industrial environments.
• Balanced I/O and Memory  Ten I/Os and approximately 57 kbits of block RAM provide a balanced feature set for control, buffering and interface tasks.
