Haskell CI Hackage Hackage Dependencies

Lattice iCE40 Primitive IP

Supported IP Modules

  • Ice40.Spram - For more information see the iCE40 SPRAM Usage Guide

    • sysMem Single Port RAM Memory (SPRAM)
    • Each block of SPRAM is 16k x 16 (256 kbits)
    • 16-bit data width with nibble mast control
    • Cascadable design for deeper/wider SPRAM
    • Three power modes, standby, sleep, and power off
  • Ice40.Mac - For more information see the DSP Function Usage Guide PDF

    • 16-bit x 16-bit Multiplier, or two independent 8-bit x 8-bit multipliers
    • Optional independent pipeline control on input Register, Output Register, and Intermediate Register for faster clock performance
    • 32-bit accumulator, or two independent 16-bit accumulators
    • 32-bit, or two independent 16-bit adder/subtractor functions, registered or asynchronous
    • Cascadable to create wider accumulator blocks
  • Ice40.Osc - For more information see the iCE40 Oscillator Usage Guide

    • on-chip oscillator
    • Low-power low frequency oscillator of 10 kHz
    • High frequency oscillator configurable to 48 Mhz, 24 Mhz, 12 Mhz, or 6 Mhz
    • See also Ice40.Clock for clock domains and reset
  • Ice40.Pll - For more information see the iCE40 sysCLOCK PLL Design and Usage Guide

    • Pad and Core variants
    • Phase Lock Loop (PLL)
    • Provides a variety of user-synthesizable clock frequencies along with custom phase delays
    • Generates a new output clock freuquency via clock multiplication and division
    • De-skews or phase-aligns an output clock to the input reference clock
    • Corrects output clock to have nearly a 50% duty cycle, which is important for Double Data Rate (DDR) applications
  • Ice40.Rgb - For more information see the iCE40 LED Driver Usage Guide

    • RGB High Current Drive I/O Pins
    • Provides sinking current to an LED connecting to the positive supply
    • Three outputs designed to drive the RGB LEDs
    • RGB drive current is user programmable from 4mA to 24mA, in increments of 4mA
  • Ice40.Led - For more information see the iCE40 LED Driver Usage Guide PDF

    • LED PWM IP
    • Provide easier usage of RGB high current drivers
    • Provides flexibility for user to dynamically change the modulation width of each of the RGB LED driver
    • User can dynamically change ON and OFF-time durations
    • Ability to turn LEDs on and off gradually with breath-on and breath-off time
  • Ice40.Spi - For more information see the Advanced SPI and I2C Usage Guide PDF

    • User SPI IP
    • Configurable Boss and Worker modes
    • Full-Duplex data transfer
    • Mode fault error flag with CPU interrupt capability

    • LSB First or MSB First data transfer
  • Ice40.IO

    • IO primitive
  • Ice40.GB

    • Global buffer primitive
    • Required for a user's internally generated FPGA signal that is heavily loaded and requires global buffering; for example, a user's logic-generated clock
  • Ice40.I2c - For more information see the Advanced SPI and I2C Usage Guide PDF

    • User I2C IP
    • Boss and Worker operation
    • 7-bit and 10-bit addressing
    • Multi-master arbitration support
    • Clock stretching
    • Up to 400 kHz data transfer speed
    • General Call support
    • Optionally delaying input or output data, or both
    • Optional filter on SCL input
