Alliance Memory Partners With Micron Semiconductor to Extend 512M SDRAM Product Life Cycle
Alliance Memory announced it has partnered with Micron Semiconductor to supply and extend availability of support for three 512M synchronous DRAM (SDRAM) devices that Micron discontinued with Micron PCN #30995 (last time buy: Feb. 28, 2014; last time ship: Oct. 31, 2015).
Alliance Memory will be offering Micron’s 32M x 16 MT48LC32M16A2P-75:C (commercial temperature), 32M x 16 MT48LC32M16A2P-75 IT:C (industrial temperature), and 64M x 8 MT48LC64M8A2P-75:C. In addition to the Micron part numbers Alliance Memory will also offer Alliance-marked 512M SDRAMs manufactured by Micron which will be 100% identical to the Micron parts.
|Micron Semiconductor part number||Alliance Memory part number||Density||Temperature rating|
|MT48LC32M16A2P-75:C||AS4C32M16SM-7TCN||32M x 16||0°C to +70 °C, commercial|
|MT48LC32M16A2P-75 IT:C||AS4C32M16SM-7TIN||32M x 16||–40°C to +85°C, industrial|
|MT48LC64M8A2P-75:C||Only will offer Micron part number||64M X 8||0°C to +70°C, commercial|
Devices with the Alliance Memory part numbers are 100% equivalent to the corresponding Micron part number, and each device has been manufactured to the same wafer/assembly and test materials and process as the corresponding Micron part number, with only the top-side marking being different. Micron will manufacture these devices.
“We thank Micron Semiconductor for working proactively with Alliance Memory to ensure that there is no disruption in the supply chain for its customers as these devices reach their EOL,” said David Bagby, president of Alliance Memory. “Micron realized that the market depended upon them heavily for this key device and has partnered with us to make sure their customers can still be supported without costly redesigns.”
“Micron is excited to partner with Alliance Memory to provide extended support of 512Mb SDR. We are committed to our customers’ success and to providing extended lifetimes on legacy products to meet and exceed our customers’ needs. Our partnership with Alliance Memory on 512Mb SDR is the execution of this commitment,” said Matthias Buchner, senior director of segment and product marketing for Micron’s compute and networking business unit.
The MT48LC32M16A2P-75:C (AS4C32M16SM-7TCN), MT48LC32M16A2P-75 IT:C (AS4C32M16SM-7TIN), and MT48LC64M8A2P-75:C are optimized for medical, industrial, automotive, and telecom applications requiring high memory bandwidth, and they are particularly well-suited to high-performance PC applications. Offered in a 54-pin TSOP II package, the devices operate from a single +3.3 V (±0.3 V) power supply and are lead (Pb)- and halogen-free.
PC100- and PC133-compliant, the devices provide programmable read or write burst lengths of 1, 2, 4, 8, or full page, with a burst termination option. An auto pre-charge function provides a self-timed row pre-charge initiated at the end of the burst sequence. Easy-to-use refresh functions include auto- or self-refresh, while a programmable mode register allows the system to choose the most suitable modes to maximize performance.
Samples and production quantities of the MT48LC32M16A2P-75 (AS4C32M16SM-7TCN), MT48LC32M16A2P-75 IT:C (AS4C32M16SM-7TIN), and MT48LC64M8A2P-75:C are available now, with lead times of six to eight weeks for large orders.
