Product information "IceZero with Lattice ICE40HX, 4 Mbit external SRAM, 3.05 x 6.5 cm"

The predecessor of this article is TE0876-02-A. All changes are in the Product Change Notification (PCN).

The IceZero is a low cost general purpose Lattice FPGA platform for the Raspberry Pi. It includes 4 Mbit of external SRAM and four 2x6 Pmod interfaces for 32 3.3V LVCMOS IO's to external expansion devices. The board is powered and configured over the standard 2x20 Raspberry Pi header. The ICE40HX4K FPGA is fully supported by Clifford Wolf’s "icoTC" Project IceStorm tool chain.

Example designs (both Verilog and Python) for the SUMP2 Logic Analyzer and general purpose GPIO (inputs, outputs, PWM servo control, etc.) are available from the Black Mesa Labs website. Mesa Bus Protocol virtual PCI 32bit communication between FPGA and Pi is supported over the Pi's 32 MHz SPI serial interface. Black Mesa Labs strives to provide multiple free open-source example designs for the IceZero platform for expanding RaspberryPi hardware interface capabilities - bitstream complete - no FPGA design experience required.

Why the Lattice iCE40?
It has a very minimalistic architecture with a very regular structure. There are not many different kinds of tiles or special function units. This makes it both ideal for creating bitstream documentations and as a reference platform for general purpose FPGA tool development.
