ICE40LP1K-CM81

The ICE40LP1K-CM81 is a field programmable gate array (FPGA) from the iCE40™ LP family. It combines 1,280 logic elements with embedded on‑chip RAM and flexible I/O to enable compact, low‑power programmable logic solutions.

Designed for low‑cost, high‑volume consumer and system applications, the device supports nonvolatile configuration memory and programmable I/O standards while operating from a 1.14 V to 1.26 V supply and across an industrial temperature range of -40 °C to 100 °C.

Key Features

• Core Logic: 1,280 logic elements (LUT + flip‑flop) for glue logic, state machines and small to mid‑size programmable logic tasks.
• Embedded Memory: Approximately 64 Kbits of on‑chip RAM (RAM4K blocks), providing local storage for buffers, FIFOs and configuration‑dependent data.
• I/O and Interface Flexibility: Up to 63 programmable I/Os with support for multiple standards including LVCMOS (3.3/2.5/1.8), LVDS25E and subLVDS; programmable pull‑ups and Schmitt‑trigger inputs are supported.
• Low Power Operation: Built on an advanced 40 nm low‑power process with standby currents as low as 21 μA (family specification), and a 1.14 V to 1.26 V operating supply for energy‑sensitive designs.
• Clocking and Configuration: Family features include multiple low‑skew global clock resources and up to two analog PLLs per device, plus flexible configuration via standard SPI or internal nonvolatile configuration memory (NVCM).
• On‑chip LED Drivers: Three high‑current LED drivers suitable for three discrete LEDs or a single RGB LED, useful for direct indicator or backlight control.
• Package and Temperature: Surface‑mount 81‑UCBGA (4 × 4 mm) package, industrial grade operation from -40 °C to 100 °C, and RoHS compliant.

Typical Applications

• Low‑cost consumer and system devices: Compact programmable logic for high‑volume consumer and embedded systems that require configurable functionality with low power consumption.
• LED indicator and lighting control: Directly drive status LEDs or an RGB LED using the device’s high‑current LED drivers for simplified board design.
• Interface bridging and signal conditioning: Use flexible I/O standards to bridge between different voltage domains and differential interfaces in compact designs.

Unique Advantages

• Highly integrated logic and memory: 1,280 logic elements paired with approximately 64 Kbits of embedded RAM reduce the need for external components.
• Small, PCB‑friendly package: 81‑UCBGA (4×4 mm) surface‑mount package saves board area while providing up to 63 I/Os.
• Low standby power: Ultra‑low power process and family standby currents as low as 21 μA support battery‑aware and always‑on applications.
• Flexible configuration options: Internal nonvolatile configuration memory or standard SPI configuration enables secure and versatile system boot flows.
• Robust operating range: Industrial temperature rating (-40 °C to 100 °C) and a narrow supply window (1.14 V to 1.26 V) for predictable behavior in demanding environments.
• Wide I/O protocol support: Programmable sysIO buffer and differential I/O support allow connection to a variety of interfaces without additional level‑shifting hardware.
