The IS42S16160D-7TLI is a 256Mb synchronous DRAM memory chip from Quarktwin Technology Ltd., designed for high-speed data transfer with a clock frequency of 143 MHz and a CAS latency of 3 clocks. It operates on a single power supply of 3.3V ¬± 0.3V and features a fully synchronous interface, allowing all signals to be referenced to the positive clock edge. The memory is organized as 4M x 16 with four internal banks, enabling efficient access and precharge hiding. This memory chip supports programmable burst lengths of 1, 2, 4, 8, or full page, and offers both sequential and interleave burst sequences. It includes auto-refresh and self-refresh modes, with 8K refresh cycles every 64 ms for commercial and industrial grades. The IS42S16160D-7TLI is available in a 54-pin TSOP-II package and is rated for an operating temperature range of 0¬8C to +70¬8C, making it suitable for various applications.
