IS42S32800B-7BL

The Integrated Silicon Solution IS42S32800B-7BL is a high-speed CMOS Synchronous Dynamic RAM (SDRAM) with a capacity of 256Mbit. It is organized as 8M x 32 bits across four internal banks, providing a memory interface that is parallel.

This device features a clock rate of up to 143 MHz and supports programmable CAS latencies of 2 or 3. The operating voltage is a single +3.3V ±0.3V, and it has an access time of 5.5 ns. The interface utilizes LVTTL.

Available in a 90-LFBGA package with a ball pitch of 0.8mm, it also supports a 0.50mm pitch for the 86-pin TSOP-2 package. The operating temperature range is 0°C to 70°C (TA). The device supports concurrent auto precharge, burst stop function, and individual byte control via DQM0-3. Refresh functions, including Auto Refresh and Self Refresh, are easily managed.

These SDRAM devices are well-suited for applications requiring high memory bandwidth, offering programmable burst lengths and burst termination operations. An auto precharge function can be enabled for self-timed row precharge at the end of a burst sequence.
