I. Core Positioning of the Series: Tailored for Lightweight, Low-Power Applications

The Lattice Semiconductor iCE40 LP series is the industry’s classic 40nm process ultra-low-power mobileFPGA™ product family, deeply optimised for battery-powered, portable wearable, edge sensing, IoT endpoints and lightweight control applications in consumer electronics. Distinct from the high-performance HX models in the same series, the LP series focuses its R&D efforts on minimising static power consumption, ultra-low standby current management and compatibility with compact, simplified packaging. It is the preferred programmable logic device for low-cost, low-computational-demand embedded applications requiring long battery life. Addressing the pain points of traditional FPGAs—high power consumption, complex configuration and bulky form factors—the iCE40 LP series has been comprehensively optimised for lightweight performance from the underlying process technology to the architectural design. It balances programmable flexibility, ultra-low operating power consumption and rapid power-up configuration capabilities, enabling the development of various hardware logic extensions, interface protocol conversions, sensor data pre-processing and customised control logic without the need for complex external power management circuits.

The series comprehensively covers a range of requirements, from entry-level minimal logic to mid-range general-purpose programmable computing power. At its core are five main mass-production models: LP384, LP640, LP1K, LP4K and LP8K. These five models share the same hardware architecture, use common development tools, and are compatible in terms of pinouts and design ecosystems. differing only in the gradation of logic resources, memory capacity, DSP processing units and I/O count. This enables them to meet the needs of minimal logic replacement in simple circuits, whilst also adapting to small-to-medium-scale digital signal processing, multi-interface expansion and complex timing control scenarios. They perfectly address the differentiated selection requirements of low-power embedded products at various levels, balancing R&D reusability with controllable mass production costs.

II. Series-Wide Common Core Hardware Architecture and Low-Power Core Advantages

Common underlying architecture design ensures seamless development compatibility

The entire iCE40 LP series adopts a unified, mature 4-input look-up table (LUT4) basic logic unit architecture, combined with Lattice’s proprietary sysMEM™ embedded memory system, programmable I/O modules and built-in non-volatile configuration memory (NVCM). This high degree of hardware architecture standardisation Once developers have completed the basic engineering design, they can seamlessly port and adapt their work across the five main models according to project resource requirements, without the need for extensive code rewriting or timing constraint adjustments, thereby significantly shortening product iteration and R&D cycles. The entire series comes standard with flexible clock management resources, a programmable PWM control module and source-synchronous I/O interfaces, supporting common digital circuit timing designs, pulse modulation control and high-speed synchronous data transmission. This eliminates the need for external clock and driver chips, simplifying peripheral circuit design.

Ultimate low-power core characteristics, optimised for battery-powered applications

As the core competitive advantage of the series, the iCE40 LP series leverages a customised 40nm low-power process to achieve industry-leading power efficiency. With a minimum static standby current of just 21μA and operating power consumption controllable at the microampere level, it significantly outperforms competing FPGAs and traditional programmable logic devices of equivalent specifications. The core operating voltage is just 1.2V, whilst the I/O voltage supports multi-level programmable adjustment, enabling compatibility with the voltage standards of various low-power MCUs, sensors and portable peripherals. This eliminates the need for multi-level voltage conversion circuits, further reducing overall system power consumption and hardware costs. It also supports a programmable low-swing differential I/O mode, which further reduces the power consumption of high-speed interfaces whilst ensuring the stability of basic data transmission. This makes it perfectly suited for applications with stringent battery life requirements, such as wearable devices, wireless sensor nodes and portable medical equipment.

The entire series integrates an NVCM (Non-Volatile Configuration Memory) unit, eliminating the need for external configuration Flash. FPGA logic configuration is completed instantly upon power-up, not only reducing the number of peripheral components and minimising PCB footprint but also avoiding additional power consumption during the power-up configuration process. This fulfils the operational requirements for ‘power-on-the-fly’ and low-power rapid boot-up, making it suitable for the frequent start-stop and low-power sleep-wake modes typical of battery-powered devices.
