概要

Description

IS42S83200J-7TLI is a high-density synchronous DRAM (SDRAM) device from ISSI’s IS42S family. It is designed as system memory for embedded and consumer applications, offering a large capacity and fast, clock-synchronous access. The “256M x 32” (organization typical for this family) provides about 1 GB total data capacity, making it suitable as a main memory or buffer in devices such as graphics or communications systems. The “-7” is the speed grade, and “TLI” indicates the package/temperature variant chosen by ISSI (leadframe/package type and operating temp range). It requires an external memory controller and a proper timing, voltage, and command sequence to perform reads/writes (RAS/CAS/WE, CE, DQ, etc.). For exact pinout, timing parameters, voltage, and packaging, consult the official ISSI datasheet.

Package

TSOP II (Thin Small Outline Package), lead-free version.

Pinout

- Pin count: 44 pins (TSOP II package, -TLI variant).
- Function: 256-Mbit Synchronous DRAM with 32M × 8 organization. It uses a multiplexed address/command bus and a bidirectional DQ data bus (DQ0–DQ7) with DQM masking. Control and bank/address signals include CS, CK, CKE, RAS, CAS, WE, BA0/BA1, A0–A12, plus Vcc/Vss. Speed grade is -7 (7 ns).

Manufacturer

Manufacturer: Integrated Silicon Solution, Inc. (ISSI).
Company type: A memory-focused semiconductor company (fabless) that designs and markets SRAM/DRAM products and outsources fabrication.

Application

IS42S83200J-7TLI is a high-speed synchronous DRAM. Common applications:
- Computer main memory (motherboards, embedded systems)
- Graphics/multimedia systems needing fast RAM
- Embedded/consumer electronics (set-top boxes, TVs, game consoles)
- Networking/telecom equipment (routers, switches)
- Industrial control and automation systems (PLCs, data loggers)

Equivalent

Equivalent parts depend on voltage and package. IS42S83200J-7TLI is a 256‑Mbit synchronous DRAM (32M × 8, 7ns). To give exact cross‑refs, please provide the package (e.g., TSOP54), voltage (3.3V or 2.5V/1.8V), and speed grade. I can then list precise 1:1 or suitable equivalents from major vendors.
