Overview

Power consumption is more and more critical in many applications, such as battery-powered equipments, very low power applications and other fields like automotive, military, etc … Thus, choosing and using a very low power external memory such as a PSRAM (Pseudo-Static RAM) memory can be a very interesting solution (less than 40 mA during burst read operations @ 104 MHz) ALSE has developed a very compact and efficient controller that can be easily integrated in any FPGA project.

Features
