Low-power SDRAM Portfolio grows with the addition of two new FBGA devices

Alliance Memory announced that the company’s portfolio of low-power SDRAMs for mobile and embedded systems in the automotive, consumer, industrial, and medical spaces continues to grow. The latest additions include two new 256Mb LPDDR2 devices: the AS4C8M32MD2A-25B2CN and AS4C8M32MD2A-25BCN.

“We’re committed to providing our customers with a complete offering of SDRAMs that combine low power consumption with power-saving features to extend battery life in mobile devices,” said David Bagby, Alliance Memory president and CEO. “From wearables to ADAS systems, our portfolio features a variety of densities and package options — now including 256Mb LPDDR2 devices in the 134-ball and 168-ball FBGA packages — to meet the needs of a wide range of applications.”

Alliance Memory’s lineup of high-speed CMOS mobile low-power SDRAMs includes SDR (LPSDR), double data rate (LPDDR), and DDR2 (LPDDR2) devices. Featuring power consumption of 1.8V, the company’s LPSDR SDRAMs are available in densities of 128Mb, 256Mb, and 512Mb in 54-ball and 90-ball FBGA packages. LPDDR devices feature power consumption from 1.7V to 1.95V and densities of 256Mb, 512Mb, 1Gb, and 2Gb in the 60-ball and 90-ball FBGA packages. Enabling ultra-slim designs, LPDDR2 SDRAMs offer power consumption of 1.2V/1.8V and densities of 256Mb, 1Gb, 2Gb, and 4Gb in the 134-ball and 168-ball FBGA packages.

For designers of mobile devices tasked with providing more functionality in tighter spaces while using less power, Alliance Memory’s low-power SDRAMs offer a variety of power-saving features, including auto temperature-compensated self-refresh (TCSR) to minimize power consumption at lower ambient temperatures. In addition, their partial-array self-refresh (PASR) feature reduces power by only refreshing critical data, while a deep power down (DPD) mode provides an ultra-low power state when data retention isn’t required.
