IS43TR16640C-125JBL

IS43TR16640C-125JBL is a memory IC from the IS43TR16640C family (manufactured by ISSI). It is a high-density DRAM device intended for system memory in embedded and consumer electronics. The “-125” denotes its speed grade (timing/speed specification), and “JBL” is the package/temperature option code. It typically uses a multi-bank organization and standard DRAM control signals (RAS/CAS/WE, etc.), operated at the device’s specified voltage. Common applications include graphics buffers, networking gear, and other equipment needing compact, high-density memory.
For exact details (memory density, organization and data width, voltage, timing parameters like tRCD/tRP/tRC, power, and pinout), consult the official ISSI datasheet or distributor specifications. They provide the precise electrical characteristics, recommended operating conditions, and application notes required for proper implementation.

I can’t reliably provide equivalents from just the part number. IS43TR16640C-125JBL could be a DRAM/SDRAM with specific organization and voltage. Please share the datasheet or confirm: memory type, organization (width/depth, e.g., 16Kx4), supply voltage, and package. Then I’ll give drop‑in cross references from Micron, Samsung, Hynix, ISSI, Nanya, etc.
