Integrated Silicon Solution, Inc. Memory IS45S32400E-7BLA1-TR

The IS45S32400E-7BLA1-TR is a 128Mb synchronous DRAM memory chip organized as 4M x 32 bits across four banks. It operates with 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 device supports clock frequencies of 166, 143, and 133 MHz, and offers programmable burst lengths of 1, 2, 4, 8, or full page, along with both sequential and interleave burst sequences. This memory chip includes an auto-refresh mode and a self-refresh capability, with 4096 refresh cycles every 16ms for A2 grade or 64ms for commercial and industrial grades. It also allows for random column addressing every clock cycle and supports programmable CAS latency of 2 or 3 clocks. The device is available in multiple package options, including an 86-pin TSOP-II and a 90-ball TF-BGA, and is suitable for various operating temperature ranges, including commercial (0¬8C to +70¬8C) and industrial (-40¬8C to +85¬8C). Engineers considering this memory chip should note its high-speed data transfer capabilities and flexibility in burst operations, making it suitable for applications requiring efficient memory access.
