ICE40LM4K-CM36

The ICE40LM4K-CM36 is an iCE40™ LM family Field Programmable Gate Array (FPGA) in a 36‑ball VFBGA package designed for ultra‑low power, compact embedded designs. It implements 3,520 logic elements and approximately 81,920 bits (≈80 Kbits) of embedded RAM alongside hardened serial interfaces and strobe generators to support sensor management, mobile and handheld applications.

With an industrial operating temperature range and a low core supply voltage window, this device targets low‑power sensor preprocessing, interface bridging and compact control functions where small form factor, integrated peripherals and robust temperature performance matter.

Key Features

• Core Logic  3,520 logic elements (LUT-based architecture) for implementing custom control, glue logic and sensor processing functions.
• Embedded Memory  Approximately 81,920 bits (≈80 Kbits) of on‑chip RAM for buffering, lookup tables and small data stores.
• Hardened Serial Interfaces  Two SPI controllers and two I²C controllers are included to simplify direct sensor and peripheral connectivity without adding external controller ICs.
• Strobe Generators  Two on‑chip strobe generators: a Low‑Power Strobe Generator (microsecond ranges) and a High‑Speed Strobe Generator (nanosecond ranges) for timing-critical sensor or interface tasks.
• High‑Drive Outputs  Three high‑drive outputs capable of source/sink nominally 24 mA for driving LEDs or other moderate‑current loads directly from the device.
• Power and Clocking  Designed on an advanced 40 nm low‑power process with flexible on‑chip clocking and a core supply range of 1.14 V to 1.26 V to support low power system designs.
• Package & Mounting  36‑VFBGA package (supplier package 36‑UCBGA, 2.5 × 2.5 mm) intended for surface‑mount PCB assembly in space‑constrained designs.
• Industrial Temperature Range  Operates from ‑40 °C to 100 °C, suitable for industrial and rugged handheld environments.
• Compliance  RoHS compliant construction for regulatory and manufacturing compatibility.

Typical Applications

• Smartphones and Mobile Devices  Always‑on sensor management and low‑power preprocessing where compact size and low standby current are critical.
• Tablets & Consumer Handhelds  Peripheral interfacing, gesture or motion preprocessing, and glue logic between sensors and application processors.
• Multi‑Sensor Management  Aggregating and preprocessing multiple sensor streams using on‑chip SPI/I²C controllers and embedded RAM to reduce host processor load.
• Industrial & Commercial Handhelds  Control, user‑interface handling and peripheral bridging in handheld devices that require industrial temperature operation.

Unique Advantages

• Highly integrated serial interfaces  Built‑in SPI and I²C controllers reduce BOM count and simplify board-level design for sensor and peripheral connectivity.
• Compact, production‑ready package  36‑ball VFBGA (36‑UCBGA 2.5 × 2.5 mm) enables small PCB footprint without sacrificing I/O count.
• Low core voltage operation  Narrow 1.14 V to 1.26 V supply window supports low‑power system architectures and efficient power management.
• On‑chip timing primitives  Dual strobe generators provide both microsecond and nanosecond timing capabilities for a wide range of sensor and timing applications.
• Embedded memory and logic density  Approximately 80 Kbits of RAM paired with 3,520 logic elements allows modest buffering and moderate‑complexity logic functions on a single device.
• Industrial temperature qualification  Rated for ‑40 °C to 100 °C operation for deployments in demanding environmental conditions.
