SDRAM increases power efficiency and performance and extends battery life

Alliance Memory has announced it has expanded its high-speed CMOS mobile low-power SDRAMs with a new single-channel 16Gb LPDDR4X device. This device combines low power ratings with increased clock speeds and data rates in the 200-ball FBGA package.

With low-voltage operation of 0.6V, the AS4C1G16MD4V-046BIN provides higher power efficiency for increased battery life in portable electronics for the consumer, commercial, and industrial markets, including smartphones, smart speakers, wearables, security surveillance systems, and other IoT devices using AI and 5G technologies.

The LPDDR4X SDRAM provides increased efficiency for advanced audio and ultra-high-resolution video in embedded applications. Its high clock frequency of 2.133GHz permits for an extremely high data rate of 4.2Gbps. The device operates over an industrial temperature range of -40C to +95C.

The device's single channel consists of eight banks of 16 bits. The component provides fully synchronous operation; programmable read and write burst lengths of 16, 32, and on the fly; and configurable drive strength. An on-chip temperature sensor controls the self-refresh rate.

The company's LPDDR4X SDRAMs provide reliable drop-in, pin-for-pin-compatible replacements for many similar solutions in high-bandwidth, high-performance memory system applications, removing the necessity for costly redesigns and part requalification.
