Low-power SDRAMs
25 September 2019, DSP, Micros & Memory

Alliance Memory has further grown its portfolio of low-power SDRAMs for mobile and embedded systems in the automotive, consumer, industrial and medical spaces. The latest additions include two new 256 Mb LPDDR2 devices: the AS4C8M32MD2A-25B2CN and AS4C8M32MD2A-25BCN.

Operating from 1,8 V, the company’s LPSDR SDRAMs are available in densities of 128 Mb, 256 Mb and 512 Mb, in 54-ball and 90-ball FBGA packages. LPDDR devices operate from 1,7 V to 1,95 V and come in densities of 256 Mb, 512 Mb, 1 Gb and 2 Gb, in 60-ball and 90-ball FBGA packages. Enabling ultra-slim designs, LPDDR2 SDRAMs offer 1,2 V/ 1,8 V operation and densities of 256 Mb, 1 Gb, 2 Gb and 4 Gb, 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 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 isn’t required.
