Integrated Silicon Solution, Inc. Memory - SDRAM - IS42S83200B-7TL IS42S83200B-7TL

The IS42S83200B-7TL is a 256Mb synchronous DRAM memory chip from Quarktwin Technology Ltd., designed to operate at a clock frequency of 143 MHz. It features a fully synchronous interface with all signals referenced to the positive clock edge, allowing for high-speed data transfer through a pipeline architecture. The memory is organized into four banks, each capable of hiding row access and precharge times, which enhances performance during burst operations. This memory chip operates on a power supply of 3.3V for both VDD and VDDQ, and it supports a LVTTL interface. It offers programmable burst lengths of 1, 2, 4, 8, or full page, along with programmable CAS latency options of 2 or 3 clocks. The device includes an auto-refresh mode and a self-refresh capability, ensuring efficient power management with 8K refresh cycles every 64 ms. The IS42S83200B-7TL is available in a 54-pin TSOP-II package and is lead-free, making it suitable for various applications, including those requiring compliance with environmental regulations. Its industrial temperature range of -40¬8C to 85¬8C further enhances its versatility for use in demanding environments.
