Visão Geral

Description

IS42S16320B-7TLI is a high-speed synchronous DRAM (SDRAM) device from ISSI/Intersil. It is a 3.3V memory with a 16,384-word by 32-bit (16K × 32) organization, operating at the -7 speed grade (roughly a 7 ns cycle time). The “TLI” suffix indicates a lead-free TSOP-II style package.
Key points:
- Interface: standard SDRAM signals (CLK, CS, RAS, CAS, WE, and DQ[31:0]), with multiplexed address/data.
- Features: multi-bank architecture, burst read/write modes, programmable CAS latency (typical CL=2/3 in SDRAMs), auto-refresh, and internal bank management.
- Power and temp: typically 3.3V supply; temperature range depends on exact device revision.
- Applications: main/system memory for embedded processors, graphics controllers, networking gear, and other high-rate memory needs.
For exact organization, timings, number of banks, refresh specs, and package details, consult the official datasheet. This is a concise introduction; specs vary by revision.

Features

IS42S16320B-7TLI is a 512‑Mbit SDRAM with 16,384 x 32 organization. Key features:
- Synchronous, clock‑driven interface with pipelined prefetch
- 4 banks; multiplexed row/column address
- Burst mode: BL = 2/4/8; burst type: sequential
- Programmable CAS latency (typical CL3/CL4 options)
- Speed grade -7 (7 ns), up to ~133 MHz data rate
- 3.3V supply (typical)
- Auto‑refresh and self‑refresh modes; optional auto‑precharge
- 54‑pin TSOP II package; lead‑free (TLI)
Applications: memory buffers, graphics, FPGAs/ASICs, and other SDRAM‑based designs.

Manufacturer

- Manufacturer: Integrated Silicon Solution, Inc. (ISSI).
- What kind of company: A fabless semiconductor company that designs and markets memory ICs (DRAM and SRAM) and sources fabrication from external foundries.

Application

IS42S16320B-7TLI is a 16M x 32-bit synchronous SRAM. Common application areas include:
- Embedded systems: fast system memory/cache for microprocessors/SoCs
- Graphics/video: frame buffers and display memory
- Networking/telecom: high-speed buffering, packet/frame buffers, DMA staging
- DSP and data acquisition: real-time data buffering and scratchpad memory
- Industrial/automotive: real-time I/O buffering and control memory
- Imaging devices: buffers for printers, scanners, cameras, and medical equipment
It serves as a fast, deterministic RAM substitute for memory-intensive, throughput-critical applications.

Package

TSOP-II package, 54-pin (Pb-free) — the IS42S16320B-7TLI uses a TSOP II 54-pin package.
