ICE40LM1K-CM36

The ICE40LM1K-CM36 is an ultra-low power field programmable gate array (FPGA) IC in a 36-ball VFBGA package. It provides a compact, configurable logic fabric—approximately 1000 logic elements with 125 CLBs—and embedded memory for sensor management and low-power mobile or industrial applications.

Designed for integration in space-constrained designs, the device combines a small 36‑UCBGA (2.5 mm × 2.5 mm) surface-mount package with a low-voltage supply range (1.14 V to 1.26 V) and an extended industrial operating temperature range (−40 °C to 100 °C).

Key Features

• Logic Capacity – Approximately 1000 logic elements organized across 125 CLBs to implement custom control and signal processing functions.
• Embedded Memory – Approximately 65,536 bits (≈64 Kbits) of on-chip RAM for buffering, state storage, and small lookup tables.
• I/O – 28 programmable I/O pins suitable for interfacing with sensors, LEDs, or host controllers.
• Low-Voltage Operation – Supported supply range from 1.14 V to 1.26 V for low-power system integration.
• Industrial Temperature Grade – Specified for operation from −40 °C to 100 °C to meet extended temperature requirements.
• Compact Package – 36‑VFBGA / 36‑UCBGA surface-mount package with a 2.5 mm × 2.5 mm footprint for tight board-level space constraints.
• Ultra-Low Power Family Characteristics – Part of the iCE40LM family, which is specified for ultra-low power operation and includes hardened interfaces and strobe generators in the family datasheet.
• RoHS Compliant – Meets RoHS environmental requirements for lead‑free assembly.

Typical Applications

• Always‑On Sensor Management – Implement low-power sensor aggregation, preprocessing and event detection while minimizing system standby consumption.
• Mobile and Handheld Devices – Small footprint and low-voltage operation make it suitable for compact consumer and industrial handheld products.
• Multi‑Sensor Fusion – On-chip RAM and programmable logic allow combining inputs from multiple sensors for feature extraction and data conditioning.
• Peripheral and GPIO Expansion – Provide additional programmable I/O, protocol bridging or custom peripheral logic in constrained designs.

Unique Advantages

• Compact, board-friendly package: The 36‑ball VFBGA (36‑UCBGA, 2.5 mm × 2.5 mm) surface-mount package reduces PCB area and simplifies placement in dense board layouts.
• Low-power system integration: Narrow supply range (1.14 V–1.26 V) and family-level ultra-low power characteristics help reduce system energy consumption.
• Industrial temperature capability: Rated for −40 °C to 100 °C, enabling deployment in environments requiring extended temperature operation.
• Right-sized logic and memory: Approximately 1000 logic elements with ~64 Kbits of on-chip RAM provide a balance of resources for control, interfacing, and signal preprocessing without excess cost or area.
• Flexible I/O count: 28 programmable I/Os simplify direct connections to sensors, actuators, and host interfaces.
• Standards‑aligned manufacturing: RoHS compliance supports modern lead‑free assembly processes.
