ICE40LM1K-CM36TR1K

The ICE40LM1K-CM36TR1K is an ultra-low power iCE40 LM family FPGA in a compact 36-VFBGA package. It provides 1,000 logic elements, approximately 65 kbits of on-chip RAM and 28 user I/Os, making it suitable for small, low-power control, sensor management and always-on processing tasks.

Built for low-voltage operation (1.14 V to 1.26 V) and industrial temperature range (-40 °C to 100 °C), this device integrates hardened SPI and I²C controllers and strobe generators from the iCE40LM series to simplify sensor interfacing and mobile or handheld system designs.

Key Features

• Core Logic  1,000 logic elements suitable for small to mid-range programmable logic functions and glue logic.
• Embedded Memory  Approximately 65 kbits of on-chip RAM for buffering, lookup tables and small data storage.
• I/O Count & Package  28 user I/Os in a 36-VFBGA package (supplier package: 36-UCBGA, 2.5 × 2.5 mm) for compact board integration.
• Low-Voltage Operation  Operates from 1.14 V to 1.26 V to support low-power system rails.
• Industrial Temperature Grade  Rated for operation from -40 °C to 100 °C for extended environmental reliability.
• Integrated Interfaces  Includes hardened SPI and I²C blocks (family feature) to interface with sensors and host processors without extra logic.
• Strobe Generators  Low-power and high-speed strobe generator capability (family feature) for timing-sensitive sensor control and capture.
• High-Drive Outputs  Family-level high current drive outputs (three HD outputs per device, source/sink nominal 24 mA) for driving LEDs or similar loads.
• Configuration  SRAM-based configuration programmable via SPI (family feature), enabling field reprogrammability.
• Compliance  RoHS compliant.

Typical Applications

• Mobile and Handheld Devices  Sensor management, peripheral bridging and low-power control in smartphones, tablets and handheld consumer devices.
• Multi-Sensor Systems  Sensor pre-processing, sensor fusion and always-on sensor handling using the integrated I²C/SPI controllers and embedded memory.
• Industrial Handhelds  Compact logic and I/O expansion for rugged handheld commercial and industrial equipment within the specified temperature range.
• Low-Power Embedded Control  Background control tasks, GPIO expansion and simple protocol bridging where low power and small form factor are priorities.

Unique Advantages

• Ultra-low power architecture: The iCE40 LM family foundation supports low-power standby and operation, enabling always-on and battery-sensitive applications.
• Integrated sensor interfaces: Hardened SPI and I²C controllers reduce external components and simplify connectivity to common sensors and processors.
• Compact package with ample I/O: 36-VFBGA (2.5 × 2.5 mm supplier package) and 28 I/Os offer a space-efficient FPGA solution for small PCBs.
• Industrial temperature range: Rated -40 °C to 100 °C to meet environmental requirements for commercial and industrial deployments.
• Flexible timing and drive: On-chip strobe generators and high-drive outputs from the family feature set enable direct control of timing-sensitive peripherals and indicators.
• Field reprogrammability: SRAM-based configuration via SPI allows design updates and in-field logic changes without hardware modifications.
