Lattice Semiconductor
6 feet (1.83 meters) in length. Connector J13 is the USB port. A FTD2232D USB transceiver (U5) translates the
USB signals to JTAG signals and is able to drive the MachXO2 device. Given this, the ispVM System software can
download bitstreams directly into the MachXO2 SRAM, or bitstreams can be downloaded into the MachXO2 Flash
memory.
LEDs
There are two LEDs on the MachXO2 Dual Sensor Interface Board that are used for general purpose signals, as
described in Table 9.
Table 9. LEDs
Low Power SDRAM Memory
The MachXO2 Dual Sensor Interface Board is equipped with a 54-ball BGA low power SDRAM device, such as the
IS42VM16400K in location U1. This provides memory resources with 16 bits of data width that span a 32M address
space. The memory is powered by an on-board 1.8V regulator. The memory connects to the MachXO2 device on
Banks 1, 3 and 4.
