IS42S16800F-7BLI

The Integrated Silicon Solution IS42S16800F-7BLI is a 128Mb Synchronous Dynamic Random-Access Memory (SDRAM) designed for high-speed data transfer. It features a fully synchronous interface, with all signals referenced to the positive clock edge. This device supports programmable CAS latency options of 2 or 3 clocks and programmable burst lengths of 1, 2, 4, 8, or full page.

Operating with a Vdd and Vddq of 3.3V, the IS42S16800F-7BLI offers clock frequencies up to 143 MHz (at CAS Latency 3) or 133 MHz (at CAS Latency 2). The access time from the clock is 5.4 ns at CAS Latency 3 and 6.5 ns at CAS Latency 2. It supports Auto Refresh (CBR) and Self Refresh modes, with 4096 refresh cycles required every 16 ms or 64 ms depending on the grade.

This SDRAM is packaged in a 54-TFBGA (8x8) and is designed for surface mount applications. The operating temperature range is -40°C to 85°C (TA). The memory is organized as 8M x 16 bits and utilizes a parallel interface.

Key features include LVTTL interface, internal bank for hiding row access/precharge, and capabilities for burst read/write operations. It is suitable for applications requiring high-speed memory access within a 3.3V system.
