- Page 2 Note: Static electricity can severely shorten the life span of electronic components. Features The LatticeXP2 Brevia Development Kit includes: • LatticeXP2 Brevia Evaluation Board – This is a small board (about the size of a business card) with the follow- ing on-board components and circuits: – LatticeXP2-5E 6TN144C –...
- Page 3 LEDs LatticeXP2 Device This board features a LatticeXP2 FPGA with a 1.2V core supply. It can accommodate all pin-compatible LatticeXP2 devices in the 144-pin TQFP (20x20 mm) package. A complete description of this device can be found in the LatticeXP2 Family Data Sheet.
- Page 4 The monitor program sends and receives data across the RS232 communications port on the LatticeXP2 Brevia Evaluation Board. It is necessary to start and configure a VT100 or ANSI style terminal emulator program like HyperTerminal (Windows) or Minicom (Linux).
- Page 5 Read SPI Flash Memory IDCode Command The SPI ROM device on the LatticeXP2 Brevia Evaluation Board can be queried and will return the ID code imple- mented by the ROM manufacturer. The LatticeMico8 initiates memory transactions using the SPI Memory control- ler to acquire the data.
- Page 6 LatticeXP2 Brevia Development Kit Lattice Semiconductor User’s Guide Read DIP Switch Bank The LatticeMico8 has the ability to read the state of switches 1-4 on the DIP switch bank. The pushbutton switches are can also be read. Each pushbutton press toggles the internal state of a register in the FPGA. The current state of the register is displayed on the high nibble of the output.
- Page 7 LatticeXP2 Brevia Development Kit Lattice Semiconductor User’s Guide Read Data History From SPI Flash Memory This command copies the Data History from the SPI ROM into the SRAM. After power is supplied, or RESET asserted the SRAM Data History log information is no longer available. Running this command permits the history to be restored from the non-volatile SPI ROM.
