IS43DR16320D-25DBI

The Integrated Silicon Solution IS43DR16320D-25DBI is a 512Mbit DDR2 Synchronous Dynamic Random-Access Memory (SDRAM) designed for high-speed operation. It features a double data rate interface, enabling two data transfers per clock cycle. This device operates with a Vdd and Vddq of 1.8V ±0.1V and supports a clock frequency of 400 MHz.

Key features include a 4-bit prefetch architecture, on-chip DLL for clock alignment, and 4 internal banks for concurrent operation. It supports programmable CAS latency (CL) from 3 to 6 and programmable additive latency (AL) from 0 to 5. The memory organization is 32M x 16, providing a total capacity of 512Mbit.

This SDRAM is available in an 84-TWBGA (8x12.5mm) surface-mount package. The operating temperature range is -40°C to 85°C (TA). Its specifications make it suitable for various memory-intensive applications requiring high bandwidth and efficient data transfer.

Designed with JEDEC standard 1.8V I/O (SSTL_18-compatible), the IS43DR16320D-25DBI offers adjustable data-output drive strength and on-die termination (ODT) options. The datasheet specifies timing parameters such as tRCD of 12.5ns and tRP of 15ns, supporting burst lengths of 4 or 8.
