The ICE40LP4K-CM81 is a low-power Field Programmable Gate Array (FPGA) IC offering 3,520 logic elements and on-chip embedded RAM for mid-density programmable logic. Designed for industrial-grade applications, it combines flexible I/O, low standby power characteristics and on-chip configuration options to address compact, power-sensitive designs.

Key Features

• Core  3,520 logic elements (LUT + flip-flop) provide mid-range programmable logic capacity suited to control, glue-logic and protocol bridging tasks.
• Embedded Memory  Approximately 81,920 bits (≈80 kbits) of embedded RAM implemented as RAM4K blocks to support buffering, small FIFOs and local data storage.
• I/O  Up to 63 programmable I/Os in the 81-VFBGA package with sysIO-style buffer support for a range of signalling standards, enabling flexible interface options.
• Low Power  Built on an advanced low-power 40 nm process; family-level data shows ultra-low standby currents for energy-sensitive applications.
• Clocking and PLLs  Eight low-skew global clock resources and support for up to two analog PLLs per device provide flexible clock distribution and deskewing options.
• Configuration  Supports standard SPI configuration and internal non-volatile configuration memory (NVCM) for compact, self-contained designs.
• Package & Mounting  81-VFBGA (supplier package format: 81-UCBGA, 4×4 mm) surface-mount package for small PCB footprint implementations.
• Electrical & Environmental  Core supply voltage range 1.14 V to 1.26 V; industrial operating temperature range −40 °C to 100 °C; RoHS compliant.

Typical Applications

• Battery-powered IoT endpoints  Low standby and active power characteristics make the device suitable for sensors and edge nodes where energy efficiency is critical.
• Sensor interfacing and data aggregation  Flexible I/O standards and embedded RAM support signal conditioning, data buffering and protocol conversion between peripherals.
• Industrial control and automation  Industrial-grade temperature range and compact package suit control logic, timing, and custom peripheral handling in industrial systems.
• Protocol bridging and glue logic  Mid-density logic and clocking resources enable consolidation of serial interfaces, bus adapters, and small state machines.

Unique Advantages

• Mid-density programmable logic: 3,520 logic elements deliver the right balance of capacity for control and interface tasks without excessive BOM complexity.
• On-chip RAM for buffering: Approximately 81,920 bits of embedded memory let you implement local FIFOs and small data stores without external RAM.
• Flexible I/O support: Programmable I/O buffers accommodate multiple signalling standards to simplify board-level interface design.
• Low-voltage operation: Narrow core supply window (1.14 V–1.26 V) supports tight power-domain designs and efficient power management.
• Industrial temperature rating: Specified operation from −40 °C to 100 °C for reliable operation in demanding environments.
• Compact, surface-mount package: 81-VFBGA (81-UCBGA, 4×4 mm) enables small PCB area and straightforward SMT assembly.
