ICE40LM1K-SWG25TR

The ICE40LM1K-SWG25TR is an ultra-low power iCE40™ LM family FPGA in a compact 25‑ball WLCSP (1.71 mm × 1.71 mm) package. It provides approximately 1,000 logic elements with embedded RAM and a set of integrated peripherals designed for mobile and always‑on sensor applications.

Targeted for space‑constrained, power‑sensitive designs, this device combines low standby power, hardened SPI and I²C blocks, and strobe generators to simplify sensor management, interface bridging, and small‑form‑factor control tasks.

Key Features

• Core Logic Approximately 1,000 logic elements suitable for compact programmable logic and glue‑logic implementations.
• Embedded Memory Approximately 64 kbits of on‑chip RAM (65,536 bits) for data buffering and small state machines.
• Integrated Interfaces Hardened SPI and I²C controllers included in the iCE40LM family simplify sensor and processor interfacing without needing external controllers.
• Strobe Generators Two on‑chip strobe generators provide low‑power microsecond‑range strobes and high‑speed nanosecond‑range strobes for timing‑sensitive sensor and LED control.
• High‑Drive Outputs Three high‑drive outputs with nominal 24 mA source/sink capability support direct LED drive and other high‑current IO tasks.
• I/O Count and Flexibility 18 I/O pins available; per‑pin pull‑up control allows flexible interfacing to sensors and external logic.
• Low Power Built on an advanced 40 nm ultra‑low power process with standby power as low as 120 μW typical (family specification), making it suitable for always‑on and battery‑powered systems.
• Clocking and Routing Six low‑skew global signal resources support synchronized clock distribution across the design.
• Package and Mounting 25‑ball WLCSP (25‑XFBGA) package, 1.71 mm × 1.71 mm, surface‑mount mounting type for very small board footprints.
• Voltage and Temperature Operating supply range 1.14 V to 1.26 V and industrial temperature range −40 °C to 100 °C.
• RoHS Compliant Device is RoHS compliant.

Typical Applications

• Smartphones and Mobile Devices — Sensor management, low‑power preprocessing, and interface bridging in compact mobile designs.
• Tablets and Handheld Consumer Devices — Small programmable logic for user interface control, peripheral management, and LED control.
• Handheld Commercial and Industrial Devices — Embedded logic and high‑drive outputs support compact instrumentation and field equipment.
• Multi‑Sensor Management — Hardened I²C/SPI interfaces, strobe generators, and embedded memory enable sensor aggregation and preprocessing.
• Always‑On Sensor Applications — Ultra‑low standby power and small package size suited for always‑on monitoring and gesture or motion front‑end tasks.

Unique Advantages

• Highly Integrated Peripherals: Hardened SPI and I²C controllers plus strobe generators reduce external component count and simplify board design.
• Compact, Low‑Power Package: 25‑ball WLCSP (1.71 mm × 1.71 mm) surface‑mount package delivers significant size savings for space‑constrained designs.
• Always‑On Efficiency: Ultra‑low standby power characteristics help extend battery life in always‑on and low‑duty‑cycle systems.
• Flexible I/O and Drive Capability: 18 programmable I/Os with per‑pin pull‑ups and three high‑drive outputs support diverse sensor and LED interfaces without external drivers.
• Industrial Temperature Range: −40 °C to 100 °C rating enables deployment in commercial and industrial environments.
• On‑Chip Memory for Local Processing: Approximately 64 kbits of embedded RAM supports buffering, small FIFOs, and temporary storage for sensor data aggregation.
