Intelligent Memory 2G/4G/8Gbit LPDDR4 DRAM with ECC

Intelligent Memory 2G/4G/8Gbit Low-Power Double Data Rate DRAM (LPDDR4) with integrated error correction (ECC) operates over the industrial temperature range and consumes less energy. The LPDDR4 devices feature a low 1.8V power supply and 1.1V at input/output. These AEC-Q100-qualified components offer a 1600MHz maximum speed with a 3200Mbps data rate and are available in a 200-ball FBGA package.
