Alliance Memory adds LPDDR2 devices to low power SDRAM portfolio

Low power SDRAMs from Alliance Memory now include 256Mbit LPDDR2 devices in 134-ball and 168-ball FBGA packages.

The AS4C8M32MD2A-25B2CN and AS4C8M32MD2A-25BCN SDRAMs are for mobile and embedded systems in the automotive, consumer, industrial, and medical spaces and can be used in wearable devices as well as advanced driver assistance systems (ADAS).

David Bagby, Alliance Memory president and CEO, explains: “Our portfolio features a variety of densities and package options — now including 256Mbit LPDDR2 devices in the 134-ball and 168-ball FBGA packages — to meet the needs of a wide range of applications.”

Alliance Memory’s 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 128, 256, and 512Mbit in 54-ball and 90-ball FBGA packages. LPDDR devices feature power consumption from 1.7 to 1.95V and densities of 256 and 512Mbit, one and 2Gbit in the 60-ball and 90-ball FBGA packages.

Enabling ultra-slim designs, LPDDR2 SDRAMs offer power consumption of 1.2/1.8V and densities of 256Mbit, one, two and 4Gbit in the 134-ball and 168-ball FBGA packages.

For designers of mobile devices which require 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 minimise 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 is not required.

Alliance Memory provides critical and hard-to-find DRAM and SRAM ICs for the communications, computing, consumer electronics, medical, automotive, and industrial markets. The company’s product range includes DRAMs and SRAMs with commercial, industrial, and automotive operating temperature ranges and densities from 64kbit to 8Gbit.

The company is privately held and maintains headquarters in San Carlos, California, and regional offices in Europe, Asia, Canada, and South America.
