Alliance Memory, Inc. Memory AS4C64M16D2A-25BINTR

The AS4C64M16D2A-25BIN is a 1Gb DDR2 synchronous dynamic random-access memory (SDRAM) device, featuring a 64Mx16 bit configuration. It operates at a clock frequency of 400 MHz and is designed for industrial temperature applications, with an operating range of -40¬8C to +95¬8C. The memory is compliant with JEDEC standards and supports a 1.8V I/O interface. This device includes eight internal banks for concurrent operations and utilizes a 4-bit prefetch architecture, allowing for efficient data access. It supports various burst lengths (4 or 8) and types (sequential or interleave), along with programmable mode and extended mode registers. The AS4C64M16D2A-25BIN also features on-die termination (ODT) and adjustable data-output drive strength, making it suitable for high-performance applications. The package dimensions are 84-ball FBGA, measuring 8 x 12.5 x 1.2 mm. Engineers considering this memory IC should note its capabilities for high-speed data processing and its suitability for environments requiring robust temperature performance.
