KIRKLAND, Wash.—Alliance Memory announced that it has expanded its DDR4 CMOS SDRAM portfolio with new “A” die versions of the 4GB AS4C256M16D4A and AS4C512M8D4 in 96 and 78 ball FBGA packages, respectively. Built on a thinner process that results in a smaller chip than the original, the AS4C256M16D4A-62BCN, AS4C256M16D4A-62BIN, AS4C256M16D4A-75BCN, AS4C256M16D4A-75BIN, AS4C512M8D4A-75BCN and AS4C512M8D4A-75BIN offer lower power consumption and higher performance speeds and transfer rates — at lower cost. Additionally, Alliance Memory continues its partnership with Micron Technology and offers the company’s MT40A1G16KH-062E DDR4 SDRAM to provide customers with a 16GB option.
To increase the battery life of portable electronic devices such as smartphones and tablets, Alliance Memory devices released today feature low operating voltages of +1.2 V (±0.06 V). DDR4s are designed, qualified, and recommended for use in 5G designs, computing applications, monitoring systems, smart meters, human-machine interfaces (HMIs), digital signal controllers, PNDs, and more. Built on new process technology, the new devices deliver fast clock speeds of up to 1600 MHz and transfer rates of up to 3200 Mbps.
The AS4C256M16D4A-62BCN, AS4C256M16D4A-62BIN, AS4C256M16D4A-75BCN, AS4C256M16D4A-75BIN, AS4C512M8D4A-75BCN, and AS4C512M8D4A-75BIN support sequential and interleaved burst types of 4 BCBL or 8 BCBL reads. An automatic precharge feature provides a self-timed line precharge initiated at the end of the burst sequence. Easy-to-use refresh features include automatic or automatic refresh.
With minimal die shrinkage, Alliance Memory’s DDR4 SDRAMs provide reliable, pin-to-pin compatible replacements for many similar solutions, eliminating the need for costly redesigns and requalification of parts. Offered in commercial (0°C to +95°C) and industrial (-40°C to +95°C) temperature ranges, the new “A” matrix devices are ideal for industrial, networking, telecommunications, gaming and consumers. markets, for which Alliance Memory uses a dual sourcing strategy to ensure longevity of supply.
The addition of Micron Technology’s MT40A1G16KH-062E to Alliance Memory’s DDR4 SDRAM offering gives enterprise customers access to a 16GB device for a wide range of applications. Operating from a +1.2V supply over a commercial temperature range, the 1Gb x 16-bit device is built on an 8n prefetch architecture for high data rates of 3200 MT/s. The MT40A1G16KH-062E supports read or write burst lengths of BC4 or BL8 on the fly.
