Description
Electronic Component Model: IS42S16800B-7BLI is a 128Mb Synchronous DRAM manufactured by ISSI. It achieves high-speed data transfer using a pipeline architecture. The clock frequency can be set at 167, 143, or 133 MHz. It has a fully synchronous design, where all signals are referenced to a positive clock edge. The module includes an internal bank for hiding row access/precharge. It operates on a power supply of VDD VDDQ, with IS42S81600B requiring 3.3V for both VDD and VDDQ. This model, IS42S16800B, also requires 3.3V for both VDD and VDDQ. The interface is LVTTL, and it supports programmable burst length options of 1, 2, 4, 8, or full page. The burst sequence can be programmed as sequential or interleave. Auto Refresh (CBR) and Self Refresh with programmable refresh periods are supported, with 4096 refresh cycles every 64 ms. The column address changes randomly every clock cycle. The CAS latency is programmable, with options of 2 or 3 clocks. It has the capability for burst read/write and burst read/single write operations. Burst termination can be triggered by the burst stop and precharge command. This model is also available in an industrial temperature and lead-free version.
