Lattice Semiconductor
Operation of the potentiometer is very simple. Whenever the CS is asserted (V
output voltage will change up/down by 1/128th. When the UP direction is requested, the output voltage will
increase.
Table 17. Digital Potentiometer Connections
SRAM
The evaluation board provides a quantity of asynchronous SRAM. The memory is organized as 256Kx32 providing
1Mbyte of storage. Asynchronous SRAMs provide a simple electrical and control interface eliminating the need for
more complex memory control systems.
