News
KIRKLAND, Wash. —Alliance Memory has expanded its offering of high-speed CMOS mobile low-power SDRAMs with four new LPDDR4X devices in a variety of densities.
As an extension to the company's fourth-generation LPDDR4 SDRAMs, the 2Gb AS4C128M16MD4V-062BAN, 4Gb AS4C256M16MD4V-062BAN, 8Gb AS4C512M16MD4V-053BIN, and 16Gb AS4C512M32MD4V-053BIN SDRAMs are designed to deliver ~50% lower power ratings in the 200-ball FBGA package for higher power efficiency.
With low-voltage operation of 0.6V, compared to 1.1V for LPDDR4 SDRAMs, the devices are designed to increase battery life in portable electronics for the consumer, commercial, and industrial markets, including smartphones, smart speakers, security surveillance systems, and other IoT devices utilizing AI and 5G technologies. Additionally, the LPDDR4X SDRAMs are also designed to provide increased efficiency for advanced audio and ultra-high-resolution video in embedded applications, and deliver fast clock speeds up to 1.86GHz for high transfer rates of 3.7Gbps.
For automotive applications, like ADAS systems, the AEC-Q100-qualified AS4C128M16MD4V-062BAN and AS4C256M16MD4V-062BAN offer a temperature range of -40°C to +105°C and on-chip ECC for increased reliability. The AS4C512M16MD4V-053BIN and AS4C512M32MD4V-053BIN operate over an industrial temperature range of -40°C to +85°C.
The AS4C512M16MD4V-053BIN, AS4C128M16MD4V-062BAN, and AS4C256M16MD4V-062BAN are organized as single-channel devices, each consisting of eight banks of 16 bits, while the AS4C512M32MD4V-053BIN offers two channels. All four components provide fully synchronous operation; programmable read and write burst lengths of 16, 32, and on the fly; and selectable output drive reliability. An on-chip temperature sensor controls the self-refresh rate.
Alliance Memory's LPDDR4X SDRAMs provide reliable drop-in, pin-for-pin-compatible replacements for similar solutions in high-bandwidth, high-performance memory system applications.
Samples and production quantities of the new LPDDR4X SDRAMs are available now, with lead times of 12 weeks. Pricing for U.S. delivery ranges from $7.45 to $17.75 in small quantities.
