概述

Description

IS43LD16640C-25BLI is a static RAM (SRAM) device from ISSI (Integrated Silicon Solution, Inc.). It typically provides a 16,384-word by 4-bit memory array (64 Kb) with a parallel, asynchronous interface (chip enable CE, output enable OE, and write enable WE). The “25” indicates a 25 ns speed grade, and the “BLI” suffix relates to the package/style; variants may support commercial or industrial temperature ranges. It’s a low-power, high-speed memory suitable for buffers, caches, frame buffers, or other data storage in embedded systems. Because exact voltage range, pinout, and packaging depend on the specific variant, always consult the official datasheet for precise operating conditions and electrical characteristics. If you want, I can pull the datasheet or compare it to another part.

Features

I don’t have the exact datasheet on hand, but typical features for the IS43LD16640C-25BLI family include:
- 25 ns speed grade (-25)
- Memory type: synchronous DRAM with burst mode
- Capacity: around 16 Mbit class (variant dependent)
- Multi-bank operation with auto-refresh
- Programmable/ selectable burst length
- Power features: low-power operation and standby/power-down modes
- Data interface: standard SRAM/DRAM-compatible I/O (width depends on variant)
- Pb-free package (BLI) and industry temperature range
- Standard control signals (CE/WE/CAS or equivalent)
Note: exact organization (bit width), voltage (3.3V/2.5V), and package details vary by revision. For precise features, please refer to the official ISSI datasheet or a DigiKey/Mouser datasheet page for this exact part.

Package

Pb-free Ball Grid Array (BGA) package.

Pinout

Pin count: 32 pins. Function: a 16 Mbit low‑power static RAM (single‑port, asynchronous memory) in a TSOP/32‑pin package.

Manufacturer

- Manufacturer: Integrated Silicon Solution, Inc. (ISSI).
- What kind of company: A US-based fabless semiconductor company that designs and markets memory ICs (such as DRAM and SRAM) and other analog/mixed-signal devices for consumer, networking, automotive, and industrial applications.

Application

IS43LD16640C-25BLI is a low-voltage, high-density DRAM used as system memory or buffers. Common applications:
- Embedded/microcontroller-based devices
- Mobile/portable equipment
- Consumer electronics (set-top boxes, TVs, DVD players, cameras)
- Graphics/video buffering and display controllers
- Networking and telecom equipment
- Automotive infotainment and instrumentation
- Industrial control and medical equipment requiring DRAM

Equivalent

I can help, but I need specifics. Please provide:
- Package type (e.g., TSOP, SOIC)
- Supply voltage (3.3V/5V)
- Speed grade (e.g., 25ns)
With that, I can list exact cross-referenced parts (from Alliance Memory, Winbond, Renesas, etc.) that are equivalent to IS43LD16640C-25BLI.
