The IS46DR16640C-25DBLA1 is a 1Gb DDR2 Synchronous Dynamic Random-Access Memory (SDRAM) from Integrated Silicon Solution, Inc. This component utilizes a double data rate interface, enabling two data transfers per clock cycle for high-speed operation. It features a 4-bit prefetch architecture and an on-chip DLL for aligning DQ and DQS transitions with the clock.
Key electrical specifications include an operating voltage of 1.8V ±0.1V, a clock frequency of 400 MHz, and an access time of 400 ps. The memory organization is 64M x 16, providing a total capacity of 1Gbit. It supports programmable CAS latency (CL) from 3 to 7 and programmable additive latency (AL) from 0 to 6, along with programmable burst lengths of 4 or 8.
This device is housed in an 84-TWBGA (8x12.5mm) package, suitable for surface mounting. The operating temperature range is -40°C to 85°C (Ambient Temperature). ISSI advises obtaining the latest specification version before placing orders and does not recommend use in life support applications without written assurance.
