概述

Description

IS42S32800D-6TL is a memory device from ISSI (Integrated Silicon Solution, Inc.): a 32M × 8-bit Synchronous DRAM (SDRAM) with a total capacity of 256 Mbit. Key points:
- Organization and interface: 32,768K words × 8 bits, uses a multiplexed address/data bus with a single clock (CLK) and standard SDRAM control signals (RAS/CAS/WE, CS, DQ).
- Voltage and speed: typical 3.3 V operation; -6 speed grade (roughly 6 ns access timing, depending on conditions).
- Features: multi-bank operation, auto-refresh, burst read/write with selectable burst lengths, synchronous operation, power-down options.
- Package/availability: offered in ISSI-standard packages; exact pinout and package type in datasheet.
- Use: common as system memory in embedded, graphics, and storage boards where compact 3.3 V SDRAM is needed.
- Reference: for pinout, timing parameters (tRC, tRCD, tMRD, etc.), and initialization, consult the official ISSI IS42S32800D-6TL datasheet.

Features

IS42S32800D-6TL is a high-density static RAM. Key features (typical from datasheet):
- Capacity: 32M x 8-bit SRAM (256 Mb total)
- Speed: 6 ns access time (speed grade -6)
- Voltage: 3.3V typical (2.7–3.6V operating range)
- Interface: Asynchronous, 8-bit I/O with control pins (CE#, OE#, WE#)
- Endurance/attributes: Static memory, unlimited write/read cycles (no refresh)
- Temperature: Wide operating range (commonly -40°C to +85°C)
- Packaging: Tape & Reel option (TL) with suitable lead-free/ RoHS compliance
- Applications: General-purpose graphics, buffers, caches, or other high-density SRAM needs
Note: Always verify exact pinout, voltage range, and temperature spec in the specific datasheet revision for your package variant.
