ICE40LP1K-CB81

The ICE40LP1K-CB81 is an iCE40™ LP Field Programmable Gate Array (FPGA) IC delivering 1,280 logic elements and approximately 65,536 bits of embedded RAM in a compact 81-pin csBGA (5×5 mm) package. Designed for low-power, cost-sensitive designs, this device combines configurable logic, embedded memory and flexible I/O in a surface-mount package rated for industrial temperature operation.

Typical use cases include low-power consumer and system applications that need configurable logic, compact footprint and deterministic I/O behavior. Key value comes from low-power architecture, on-chip memory and a variety of programmable I/O and configuration options.

Key Features

• Core Logic — 1,280 logic elements (LUT + flip-flop) providing programmable combinational and sequential logic capacity for control, glue logic and small to moderate custom functions.
• Embedded Memory — Approximately 65,536 total RAM bits of on-chip memory for buffers, FIFOs and state storage.
• I/O Count & Flexibility — 62 programmable I/O pins with support for programmable low-swing differential I/O and a flexible sysIO buffer that supports multiple interface standards.
• Low-Power Architecture — Part of the iCE40 LP family manufactured on a low-power process; family features include ultra low standby currents and power-management options.
• Flexible On-Chip Clocking — Up to eight low-skew global clock resources and analog PLL support as provided by the iCE40 family for synchronized, deterministic clock distribution.
• Configurable Boot Options — SRAM-based configuration with support for standard SPI configuration and internal Nonvolatile Configuration Memory (NVCM) as provided by the iCE40 family.
• High-Current LED Drivers — Family-level support for high-current LED drivers suitable for driving multiple LEDs or an RGB LED where hardware requires it.
• Voltage & Temperature — Supply voltage range of 1.14 V to 1.26 V and industrial operating temperature range from −40 °C to 100 °C.
• Package & Mounting — 81-pin csBGA (5×5 mm) package, surface-mount mounting type, RoHS compliant.

Typical Applications

• Consumer & Portable Electronics — Implement custom control logic, low-power peripherals and LED/user-interface drivers while minimizing board area.
• Sensor & IoT Edge Nodes — Local data conditioning, protocol bridging and low-power interfacing for battery-operated or always-on endpoints.
• User Interface Control — Manage button/switch input conditioning, LED driving and simple state machines with compact on-chip memory for UI state.
• Embedded System Glue Logic — Replace multiple discrete components with programmable logic for bus bridging, timing alignment and small protocol adaptation tasks.

Unique Advantages

• Compact, production-ready package: The 81-pin csBGA (5×5 mm) enables small PCB footprints while providing a full set of programmable I/Os.
• Low-voltage operation: Narrow supply range (1.14–1.26 V) supports designs targeting low-voltage power rails and tight power budgets.
• Industrial temperature rating: Rated for −40 °C to 100 °C operation to meet a wide range of environmental requirements.
• On-chip memory integration: Approximately 65,536 bits of embedded RAM reduce external memory needs for many control and buffering tasks.
• Flexible configuration options: Support for SPI configuration or internal NVCM simplifies board-level design and boot workflows.
• Family-level low-power features: iCE40 LP family characteristics include ultra-low standby currents and programmable I/O features that help reduce system power.
