IS43DR16640C-3DBLI

IS43DR16640C-3DBLI is a synchronous DRAM (SDRAM) device from Integrated Silicon Solution, Inc. (ISSI). It’s designed for system memory expansion in embedded, consumer, and graphics-related applications, offering a high-speed, multi-bank memory array with a multiplexed address/command interface and burst data access. The part supports standard SDRAM features such as auto-refresh, precharge control, and variable CAS latency options per JEDEC standards.
The suffixes indicate packaging/voltage/grade options: “-3D” typically points to a 3.3V operation and specific speed/density family, while “-BLI” denotes the package variant and temperature/lead-free specification. Exact organization (data width and total capacity), timing parameters (tRC, tRP, tRCD, CL), and operating conditions vary by device variant and vendor revision.
For precise details, timings, recommended operating conditions, and pinout, refer to the official ISSI datasheet and application notes for IS43DR16640C-3DBLI. If you’re selecting this part for a design, verify the exact variant with ISSI or your distributor.
