ICE40LP8K-CM81

The ICE40LP8K-CM81 is an iCE40™ LP family Field Programmable Gate Array (FPGA) in an 81‑ball ucBGA package. It delivers 7,680 logic elements with 131,072 total on-chip RAM bits and up to 63 general-purpose I/O pins, targeting low-power, space-constrained embedded applications.

Designed for industrial operation, the device supports a narrow core supply range (1.14 V to 1.26 V) and an operating temperature range of −40 °C to 100 °C. Family-level features include ultra-low power operation and flexible I/O and configuration options suitable for consumer and system-level designs where low power and compact integration matter.

Key Features

• Core Logic — 7,680 logic elements providing programmable LUT-based logic for glue logic, state machines, and custom datapath implementations.
• Embedded Memory — 131,072 total RAM bits (family datasheet references approximately 128 kbits of embedded block RAM) for buffering, small FIFOs, and local data storage.
• I/O and Interfaces — Up to 63 I/O pins in the 81‑ball ucBGA package; programmable I/O buffer options in the family include support for LVCMOS (3.3/2.5/1.8 V) and differential signaling (LVDS25E, subLVDS) per the family datasheet.
• Power and Configuration — Core supply range 1.14 V to 1.26 V; iCE40 family devices are characterized for ultra-low standby current (family note: as low as 21 μA). Configuration options include standard SPI interface and internal Nonvolatile Configuration Memory (NVCM) as described in the family datasheet.
• Clocking — Family-level clocking resources include multiple low-skew global clocks and up to two analog PLLs per device for flexible clock management.
• Package and Mounting — 81‑VFBGA / 81‑ucBGA (4 × 4 mm) supplier package, surface-mount device optimized for compact PCB layouts.
• Industrial Temperature Rating — Qualified for operation from −40 °C to 100 °C, suitable for industrial environments.
• Compliance — RoHS compliant.

Typical Applications

• Low-power embedded controllers — Compact FPGA logic and low standby currents make this device suitable for battery-aware or energy-sensitive embedded systems.
• I/O expansion and interface bridging — Use the programmable I/O and flexible buffering options to adapt between different logic levels and differential interfaces.
• Consumer and system electronics — The iCE40 family is positioned for low-cost, high-volume consumer and system applications that benefit from integrated memory and on-chip configuration.
• Industrial control and monitoring — Industrial temperature range and surface-mount ucBGA packaging enable deployment in compact industrial sensor and control modules.

Unique Advantages

• High integration in a small footprint — 7,680 logic elements and embedded RAM in a 4 × 4 mm ucBGA package reduce PCB area and BOM count.
• Low-voltage, low-power operation — Narrow core voltage range (1.14–1.26 V) and family-level ultra-low standby support help minimize system power consumption.
• Flexible I/O support — Programmable I/O buffers and differential interface options simplify interfacing to a variety of external devices and sensors.
• On-chip configuration options — Support for SPI configuration and internal NVCM enables multiple deployment and boot strategies without external controllers.
• Industrial-grade thermal range — Rated for −40 °C to 100 °C operation, allowing use in demanding environmental conditions.
• Supplier packaging for production — 81‑UCBGA (4×4) supplier device package and surface-mount mounting ease automated assembly and high-volume manufacturing.
