ICE40LM1K-CM49

The ICE40LM1K-CM49 is an ultra‑low power field programmable gate array (FPGA) offering 1,000 logic elements and 37 user I/Os in a compact 49‑VFBGA (49‑UCBGA 3×3) surface‑mount package. The device targets sensor manager and mobile/handheld applications, combining programmable logic, embedded RAM, and hardened serial interfaces for compact, low‑power system designs.

Built around the iCE40LM family architecture, the part integrates on‑chip memory and dedicated peripherals to simplify sensor interfacing, SPI/I²C bridging, strobe generation and other always‑on or low‑power tasks while supporting industrial temperature ranges and RoHS compliance.

Key Features

• Logic Capacity  Approximately 1,000 logic elements (LUT-based fabric) suitable for control, glue logic and small sensor‑processing tasks.
• Embedded Memory  65,536 bits of on‑chip RAM for buffering and local data storage.
• I/O and Peripherals  37 programmable I/Os with flexible per‑pin options; includes family‑level hardened peripherals such as two I²C controllers and two SPI controllers for sensor and host interfaces.
• Strobe Generators  Family architecture includes two on‑chip strobe generators: a Low‑Power Strobe Generator (microsecond range) and a High‑Speed Strobe Generator (nanosecond range) to support varied timing needs.
• High‑Drive Outputs  Family features include high current drive outputs (three HD outputs per device, source/sink nominal 24 mA) for direct LED or load driving where applicable.
• Power  Narrow operating core voltage range of 1.14 V to 1.26 V to support low‑power system designs.
• Clocking Resources  Flexible on‑chip clocking with multiple low‑skew global routing resources (family feature) to simplify timing-critical paths.
• Package & Mounting  49‑VFBGA (supplier package: 49‑UCBGA 3×3) surface‑mount package optimized for compact board layouts.
• Temperature & Compliance  Industrial operating range −40 °C to 100 °C and RoHS compliant for broad commercial and industrial deployment.

Typical Applications

• Mobile and Handheld Devices  Always‑on sensor management, interface bridging and low‑power control functions in smartphones, tablets and portable consumer devices.
• Sensor Management & Fusion  Pre‑processing, aggregation and protocol bridging for multi‑sensor systems using embedded RAM and hardened SPI/I²C controllers.
• Industrial Handhelds  Compact FPGA logic for user interface control, peripheral bridging and timing generation in commercial and industrial handheld equipment.
• Low‑Power Embedded Systems  Ultra‑low power standby and active modes suitable for battery‑sensitive applications requiring persistent monitoring or intermittent processing.

Unique Advantages

• Compact, production‑ready package: The 49‑VFBGA (3×3) surface‑mount package enables high‑density board designs with 37 available I/Os.
• Integrated serial peripherals: Two hardened I²C and two hardened SPI controllers reduce external component count and simplify sensor/host connectivity.
• On‑chip RAM for local buffering: 65,536 bits of embedded memory allow local data storage and lower latency in signal processing tasks.
• Low core voltage: Operates between 1.14 V and 1.26 V to support low‑power system architectures and efficient power budgeting.
• Industrial temperature support: −40 °C to 100 °C operating range makes the device suitable for a wide range of commercial and industrial environments.
• RoHS compliant: Meets environmental compliance requirements for modern manufacturing and distribution.
