ICE40LM1K-CM49TR1K

The ICE40LM1K-CM49TR1K is a field programmable gate array (FPGA) in the iCE40™ LM family, offering a compact, industrial-grade programmable logic solution in a 49-ball VFBGA package. It combines approximately 1,000 logic elements with on-chip RAM and a 37-pin I/O complement to address always-on sensor management, mobile-adjacent peripherals, and compact embedded control tasks.

Designed around the iCE40LM family architecture, the device supports low-power operation and integrated peripheral blocks for common embedded interfaces and sensor workflows, delivering a small-footprint, programmable building block for space-constrained and industrial-temperature applications.

Key Features

• Core Logic — 1000 logic elements suitable for control logic, glue-logic and small to mid-size programmable functions.
• Embedded Memory — 65,536 bits (64 kbits) of on-chip RAM for buffering, state storage and lightweight data processing.
• I/O Count — 37 user I/O pins to interface with sensors, peripherals and host processors.
• On‑chip Interfaces and Peripherals — iCE40LM family devices include integrated SPI and I²C controller blocks and on-chip strobe generators for microsecond and nanosecond timing needs.
• Low‑Power Architecture — Family-level ultra-low power process and features targeted at always‑on and mobile-style sensor management applications.
• Package — 49-VFBGA (supplier package: 49-UCBGA, 3×3 mm) providing a compact footprint for space-constrained boards.
• Supply Voltage — Operates from 1.14 V to 1.26 V, enabling integration with low-voltage domains.
• Industrial Temperature Range — Qualified for operation from –40 °C to 100 °C for reliable performance in demanding environments.
• Regulatory — RoHS compliant.

Typical Applications

• Mobile and Handheld Peripherals — Compact programmable logic for sensor pre-processing, protocol bridging or custom peripheral functions in small devices.
• Always‑On Sensor Management — Low-power logic and integrated interface blocks for managing multiple sensors with minimal host intervention.
• Industrial Embedded Control — Industrial temperature rating and compact package for control, monitoring, and interface tasks in industrial handhelds and instrumentation.
• User Interface & LED Drive — Programmable outputs and timing resources to implement simple user interfaces, LED control and strobe timing functions.

Unique Advantages

• Compact, BOM‑friendly Package: A 49-ball VFBGA in a 3×3 mm supplier footprint reduces board area and supports dense, portable designs.
• Integrated Interfaces: Hardened SPI and I²C blocks plus on-chip strobe generators lower external component count and simplify sensor interfacing.
• Low-Voltage Operation: Narrow supply range (1.14–1.26 V) aligns with low-voltage system domains to simplify power sequencing and interfacing.
• Industrial Reliability: Specified for –40 °C to 100 °C operation to meet extended-temperature deployment requirements.
• Right‑sized Resources: ~1,000 logic elements and 64 kbits of embedded RAM provide a balance of programmable logic and memory for control, glue logic, and lightweight signal processing.
• Standards‑oriented Design: RoHS compliance supports regulatory needs for modern electronics manufacturing.
