Integrated Silicon Solution, Inc. Memory IS45S16400F-7BLA1-TR

The IS45S16400F-7BLA1-TR is a 64Mb synchronous dynamic RAM (SDRAM) organized as 1 Meg x 16 bits across 4 banks, designed for high-speed data transfer with a clock frequency of up to 200 MHz. It operates on a single 3.3V power supply and features a fully synchronous interface, with all signals referenced to the positive edge of the clock. The memory supports programmable burst lengths of 1, 2, 4, 8, or full page, and allows for both sequential and interleave burst sequences. This SDRAM includes self-refresh modes and auto-refresh capabilities, with a refresh cycle of 4096 every 64 ms for commercial and industrial grades, or every 16 ms for automotive grade A2. The device is compatible with LVTTL signaling and offers programmable CAS latency options of 2 or 3 clocks. It is available in a 54-pin TSOP II or 54-ball FBGA package, with operating temperature ranges suitable for commercial, industrial, and automotive applications. Engineers considering this memory for their projects should note its high-speed performance, flexible burst options, and compatibility with various operating conditions.
