The IS42S32400E-7BL is a 128Mb synchronous DRAM memory chip from Quarktwin Technology Ltd., designed for high-speed data transfer with a clock frequency of 143 MHz. It operates on a single power supply of 3.3V ¬± 0.3V and features a fully synchronous interface, with all signals referenced to the positive edge of the clock. The memory is organized as 4 banks of 1M x 32 bits, allowing for efficient access and data handling. 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 a refresh cycle of 4096 every 64 ms for commercial and industrial grades. The device is compatible with LVTTL signaling and provides programmable CAS latency options of 2 or 3 clocks. The IS42S32400E-7BL is available in a 90-ball TF-BGA package and is suitable for commercial temperature ranges from 0¬8C to +70¬8C. It is designed for applications requiring reliable and fast memory access, making it a suitable choice for various electronic projects.
