Visão Geral
Description
IS42S83200J-7TLI is an ISSI synchronous DRAM (SDRAM) device from the IS42S family. It is a high-density, multi-bank memory intended for system RAM/graphics/embedded memory subsystems, accessed via a clocked, multiplexed address/command interface under a memory controller.
Key points:
- Speed grade: -7 (typical 7 ns)
- Data interface: wide data bus (often 32-bit, with other density/organization options in the same family)
- Core features: auto-refresh, multi-bank operation, standard SDRAM timing (tRCD, tRP, tCAS, tREF), and low-power modes
- Packaging/alias: suffixes (such as -7TLI) indicate package/RoHS/lead-free options and packaging variant
Voltage and exact organization (e.g., density, x8/x32 data width), as well as precise timing parameters, vary by part revision. For accurate specs, timing diagrams, and electrical characteristics, refer to the official IS42S83200J-7TLI datasheet from ISSI.
