ICE40LP1K-QN84

The ICE40LP1K-QN84 is an iCE40™ LP Field Programmable Gate Array (FPGA) offered in an 84-pin VFQFN dual-rows package with exposed pad. It delivers a balanced combination of programmable logic, on-chip memory and flexible I/O for low-power, embedded and consumer system designs.

Built for compact, industrial-temperature applications, this device provides 1,280 logic elements, approximately 65,536 bits of embedded RAM, and 67 programmable I/O pins, with a nominal supply range of 1.14 V to 1.26 V.

Key Features

• Logic Capacity  1,280 logic elements (LUT + flip-flop) suitable for moderate-density programmable logic implementations.
• Embedded Memory  Approximately 65,536 bits of on-chip RAM for frame buffers, small data buffers and state storage.
• I/O Flexibility  67 programmable I/O pins with family-level support for a broad range of interfaces, including programmable low-swing differential and common LVCMOS signaling.
• Low-Voltage Operation  Device supply range from 1.14 V to 1.26 V, supporting low-power system designs.
• Ultra-Low-Power Family Features  iCE40 LP family-level ultra-low-power characteristics are documented in the datasheet (standby currents as low as 21 μA), enabling low-power standby and always-on functions.
• Clocking  Family-level clock architecture includes multiple low-skew global clock resources and support for analog PLLs (up to two per device as documented in the family datasheet).
• Configurable Boot Options  Family-supported configuration options include standard SPI interface programming and internal nonvolatile configuration memory (NVCM) for flexible system start-up modes.
• Package and Mounting  84-VFQFN dual rows with exposed pad (supplier package: 84-QFN, 7 mm × 7 mm), surface-mountable for compact PCB designs.
• Industrial Temperature Range  Rated for operation from −40 °C to 100 °C for deployment in environmentally demanding applications.
• Compliance  RoHS compliant packaging to support regulatory and manufacturing requirements.

Typical Applications

• Consumer and High-Volume Systems  Compact programmable logic for low-cost, high-volume consumer or system designs that require on-board customization and control.
• LED and Display Control  Family-level high-current LED driver support enables single-package solutions for multi-LED or RGB indicator control.
• Interface Bridging and I/O Conditioning  Programmable I/O and source-synchronous features make the device suitable for bridging between sensors, peripherals and host controllers.
• Embedded Logic and Glue Logic  Use as an integrated glue-logic element to consolidate discrete components and simplify board-level design.

Unique Advantages

• Balanced Logic and Memory: 1,280 logic elements paired with ~65 Kbits of embedded RAM provides a compact, integrated resource set for moderate complexity designs.
• Low-Power Operation: Narrow supply range (1.14–1.26 V) and documented family-level low standby currents support energy-efficient designs and reduced system power.
• Flexible I/O: 67 I/Os and family-supported programmable sysIO buffers enable a wide range of interface signaling options to simplify integration.
• Compact, PCB-Friendly Package: 84-pin QFN footprint with exposed pad (7 mm × 7 mm supplier package) allows dense board layouts while supporting thermal dissipation through the pad.
• Industrial Temperature Rating: −40 °C to 100 °C operating range supports deployment in temperature-demanding applications.
• Design Flexibility: Internal nonvolatile configuration memory and SPI configuration options enable flexible boot and field-update strategies.
