Categories: Memory Controllers
Quality Control: Learn More
The Intel 82840 is a CMOS DRAM controller designed for high-performance computing applications. This component features a 64-bit external data bus and supports a 36-bit address bus, enabling memory organizations of 256M x 64. Operating at a nominal supply voltage of 1.8000V, it integrates low-power modes for enhanced efficiency. The 82840 is housed in a 544-pin PBGA (Plastic Ball Grid Array) package with a terminal pitch of 1.27mm, suitable for surface-mount assembly. Its bus compatibility extends to Pentium III and Pentium II processors. This device is utilized in systems requiring advanced memory management and is commonly found in server and workstation platforms.
