Interface - Wearables

Are you constrained by I/O limitations of your application processor? Lattice FPGAs can help. Add what you need, the way you need it by using Lattice FPGAs.

Flexibility - Lattice FPGAs support numerous I/O standards that provide the flexibility to interface with a wide range of sensors, memory, panels etc. Use Lattice FPGAs for low cost, low power instant innovation.

I/O rich FPGAs - Lattice FPGAs are designed with multiple I/O banks each capable of supporting independent I/O voltages, ideal for GPIO I/O expansion

Block Diagrams

SPI to MIPI DSI

  • Lowest power FPGA with MIPI D-PHY support on the market
  • Using only 3.1K Logic Cells, 1 PLL, and 6x DSP blocks, users can now implement our MIPI D-PHY IP to directly connect and bridge SPI to MIPI CSI2 or SPI to MIPI DSI
  • With the addition of smart memory within iCE40UltraPlus, you can also buffer full or partial frames for a variety of user scenarios. One such scenario is multi-layer graphics acceleration

Parallel to color sequential display bridge

  • Does your wearable device AP not support color sequential displays?  Use Lattice FPGAs to convert the parallel RBG stream to color sequential R,G & B data required by the display
  • Lattice FPGAs support several interface standards and protocols such as LVDS, parallel RGB, MIPI DSI, etc. to meet your unique bridging requirements

Always-on controller and display bridge

  • Use low power & small form factor Lattice FPGAs to implement always on wearable display functionality while still meeting your system’s power budget
  • Lattice FPGAs include integrated oscillators & PLLs that can be used to implement other custom features on demand

I/O level shifter and auto time calibration

  • Lattice FPGAs include multiple I/O banks with independent voltage-level control to create custom voltage-level translator bridge solutions
