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.
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.
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.
