New iCE40 UltraPlus™ Devices from Lattice Semiconductor Accelerate Customer Innovation in Smartphones and IoT Edge Devices

Lattice Semiconductor Corp., a provider of customizable smart connectivity solutions, announced its iCE40 UltraPlus FPGA devices, an energy-efficient & programmable mobile heterogeneous computing (MHC) solutions. This addition to the iCE40 Ultra family delivers eight times more memory (1.1 Mbit RAM), twice the digital signal processors (8x DSPs), and improved I/Os over previous generations. Available in multiple package sizes, the programmable nature of the iCE40 UltraPlus device is ideal for smartphones, wearables, drones, 360 cameras, human-machine interfaces (HMIs) and industrial automation, as well as security and surveillance products.

Enabling a new way to interact with electronic devices, the iCE40 UltraPlus device is suited for voice recognition, gesture recognition, image recognition, haptics, graphics acceleration, signal aggregation, I3C bridging and more. This brings added intelligence to smartphones and IoT edge products, such as wearables and home audio assisted devices, to be always on, always listening and ready to instantly process commands locally without going to the cloud.

The MHC paradigm is concentrated around a highly energy-efficient method for computing algorithms quickly and locally using dissimilar processors to offload power hungry application processors (APs) in battery-powered devices. More DSPs offer the ability to compute higher-quality algorithms, while increased memory allows data to be buffered for longer low-power states. The flexible I/Os enable a more distributed heterogeneous processing architecture. This combination provides flexibility to enable OEMs and the Maker market to quickly deliver innovations such as always on sensor buffers and acoustic beam forming.

Applications include, but are not limited to:

• Always-on sensor buffer & distributed processing for mobile devices at sub-1 mW power consumption
o Always-on sensor functionality while the AP is in sleep mode
o Enables functions such as gesture detection, facial recognition, audio enhancement, audio beam forming, phrase detection, double tap, shake-to-wake and pedestrian dead reckoning (PDR)
• Frame buffer and graphics acceleration for wearables and white goods
o Always-on display while AP is in sleep mode
o Interface bridge from MCU to display
o Multi-layer graphics acceleration for improved system power consumption
• Microphone array beamforming for battery-powered mobile devices
o Superior audio quality using multiple mics for background noise reduction as well as audio equalization
• Aggregating various GPIOs, SPI, UART, I2C, I3C signals and more over a single PCB trace eliminates routing contention issues to reduce system cost and simplify designs

Key features of the iCE40 UltraPlus product include:

• Integrated 1.1 Mb SRAM, 8 DSP blocks, up to 5K LUTs and Non-Volatile Configuration Memory (NVCM) for instant-on applications
• MIPI-I3C support for low-resolution, always-on camera applications
• Sub 100 micro watt of standby power consumption
• Compact form factor with package sizes starting as low as 2.15 x 2.55 mm for space-constrained consumer markets
• QFN package suitable for addressing industrial market needs
• Ideal for critical low-latency acceleration functions
