IS42S83200J-7TLI

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.

Here are the typical features of IS42S83200J-7TLI (summary):
- Density/organization: High-density SDRAM (~256 Mb; commonly 32M × 8 or 8M × 32)
- Type: Synchronous DRAM (SDRAM)
- Speed grade: -7 (approximately 7 ns)
- Voltage: 3.3V nominal (± tolerance)
- Banks: 4 banks
- Burst: Burst length options (2/4/8), with sequential/interleaved burst modes
- CAS latency: Programmable options (e.g., CL 2/3/4 depending on mode)
- Refresh: Auto-refresh and self-refresh capability
- Packaging: Pb-free TLI package
- Operating temp: Typically -40°C to 85°C (industrial grade variants)
Note: Exact organization, timings, and voltage tolerances depend on the specific mode/register settings and the device revision. For precise specs, consult the datasheet.

Pin count: 84 pins (in the typical TSOP-II package for IS42S83200J-7TLI).
Function: 256 Mb synchronous DRAM with a 32-bit data bus (organized as 8M x 32), banked with typical DRAM control signals (RAS, CAS, WE, CS, CLK, etc.). Note: packaging options can vary; verify the exact package in the datasheet.

Manufacturer: Integrated Silicon Solution, Inc. (ISSI).
What kind of company: ISSI is a fabless semiconductor company that designs and markets memory products (DRAM, SRAM, PSRAM) and outsources fabrication to foundries.

IS42S83200J-7TLI is a high-density DRAM used as volatile system memory. Typical application areas include:
- Main memory for desktops, notebooks, and servers
