Integrated Silicon Solution, Inc. Memory IS46R16320E-6BLA1

The IS46R16320E-6BLA1 is a 512Mb DDR SDRAM memory chip from Quarktwin Technology Ltd., designed for high-speed data transfer with a double-data rate architecture that allows two data transfers per clock cycle. It operates at a voltage of 2.5V ¬± 0.2V and is compatible with SSTL_2 I/O standards. The device features a bidirectional data strobe (DQS) for capturing data, with commands entered on the positive edge of the clock signal. This memory chip supports four internal banks for concurrent operations and offers programmable CAS latency options of 2, 2.5, and 3, along with burst lengths of 2, 4, and 8 in both sequential and interleave modes. It includes Auto Refresh and Self Refresh modes, as well as concurrent Auto Precharge support. The IS46R16320E-6BLA1 is available in a 60-ball BGA package and is rated for automotive applications with an operating temperature range of -40¬8C to +85¬8C. Engineers considering this product should note its specifications for speed, temperature range, and compatibility with various configurations, making it suitable for a range of applications in automotive and industrial environments.
