Description

IS42S16400D-7TLI is a high-density static RAM from ISSI. It provides 64 Mbit of storage organized as 16,777,216 words × 4 bits (16M × 4).
Key features
- Parallel, asynchronous SRAM with 4 data I/O lines (DQ0–DQ3) and 24 address inputs (A0–A23).
- Three-state outputs with CS/CE, OE, and WE control signals.
- Speed grade -7 = access time of about 7 ns.
- Supply voltage typically 3.0 V–3.6 V (nominal ~3.3 V); variations exist for different grades.
- Available in common SRAM packages (e.g., 48‑pin), with commercial/industrial temperature options.
Usage notes
- Ideal for buffers, caches, frame buffers, and embedded systems needing fast, random access memory.
- Can be paired to build wider data buses (e.g., two devices for 8‑bit, four for 16‑bit) or used in multi‑device memory maps.
For exact electrical characteristics, timing, and packaging options, refer to the official ISSI datasheet.

Package

TSOP-II package (54-pin).

Pinout

- Pin count: 28 pins
- Function: 64Kbit static RAM organized as 16K × 4 (IS42S16400D). It provides asynchronous read/write with:
- Address lines: A0–A13 (14 lines)
- Data I/O lines: IO0–IO3 (4 lines)
- Control: CE# (chip enable, active low), OE# (output enable, active low), WE# (write enable, active low)
- Power: Vcc and GND
Package variant: -7TLI (speed/package code).

Manufacturer

- Manufacturer: Integrated Silicon Solution, Inc. (ISSI).
- Company type: A US-based semiconductor company that designs and markets memory ICs (DRAM and SRAM); it is a fabless memory company, outsourcing manufacturing to foundries.

Application

IS42S16400D-7TLI is a high-speed 64‑Kbit SRAM (16K × 4). Typical applications: general-purpose data storage and buffering in microprocessor/ASIC/DSP systems; caches and lookup tables; frame buffers for LCDs/graphics; video/image processing buffers; networking equipment memory (routers/switches); automotive/industrial control modules; any system requiring fast, low-latency static RAM.
