ICE40LM4K-CM49TR1K

The ICE40LM4K-CM49TR1K is an industrial‑grade, ultra‑low power field programmable gate array (FPGA) in a 49‑VFBGA package. Built on the iCE40LM family architecture, it provides programmable logic, embedded block RAM and hardened serial interfaces targeted at mobile and always‑on sensor management applications.

With 3,520 logic elements, approximately 80 kbits of embedded memory and 37 user I/Os, this surface‑mount device delivers compact, power‑efficient programmable logic suitable for sensor interfacing, pre‑processing and low‑power control tasks across industrial and handheld designs.

Key Features

• Logic Density  3,520 logic elements to implement combinational and sequential logic functions for control, interface bridging and signal processing.
• Embedded Memory  Approximately 80 kbits of on‑chip RAM for buffering, small FIFOs or state storage directly within the FPGA fabric.
• Interfaces  Two hardened I²C controllers and two hardened SPI controllers provide integrated, low‑overhead serial connectivity for sensors and peripherals.
• Strobe Generators  Integrated low‑power and high‑speed strobe generators enable timing control in microsecond and nanosecond ranges for sensor or LED timing applications.
• High‑Drive Outputs  Three high‑drive outputs with nominal source/sink of 24 mA for driving LEDs or other moderate current loads.
• Clocking  Six low‑skew global signal resources for flexible on‑chip clock distribution and timing routing.
• Power  Ultra‑low power architecture with device supply range of 1.14 V to 1.26 V, optimized for always‑on and battery‑sensitive applications.
• Package & Mounting  49‑VFBGA (supplier package: 49‑UCBGA, 3×3 mm); surface‑mount package for compact PCB integration.
• Operating Range  Industrial operating temperature range from −40 °C to 100 °C for robust field use.
• Compliance  RoHS compliant to support environmental requirements in manufactured products.

Typical Applications

• Mobile and Handheld Devices  Sensor management and interface bridging in compact consumer or commercial handhelds where low power and small footprint are required.
• Always‑On Sensor Systems  Low‑power sensor pre‑processing, fusion and wake logic for systems that require continuous monitoring with minimal energy draw.
• Multi‑Sensor Management  Aggregation and control of multiple sensor buses using the built‑in I²C and SPI controllers for simplified BOM and integration.
• Embedded Control and User Interfaces  Implement custom control logic, LED drive and timing functions using the strobe generators and high‑drive outputs.

Unique Advantages

• Ultra‑Low Power Operation: The iCE40LM architecture and 1.14–1.26 V supply range enable low standby and active power behavior suitable for battery‑sensitive applications.
• Integrated Serial Peripherals: Two hardened I²C and two hardened SPI controllers reduce external components and simplify sensor and peripheral interfacing.
• Compact, Surface‑Mount Package: 49‑VFBGA (3×3 mm supplier package) minimizes PCB area for space‑constrained designs.
• On‑Chip Memory: Approximately 80 kbits of embedded RAM reduces the need for external memory for small buffering and state storage tasks.
• Industrial Temperature Range: Rated from −40 °C to 100 °C to support deployment in demanding environmental conditions.
• Design Ecosystem Support: The iCE40LM family is supported by vendor design tools and reference IP to accelerate implementation and validation of designs.
