IS42S16400D-7TLI

IS42S16400D-7TLI is a high-speed, low-power static RAM (SRAM) from ISSI. It provides 16K × 8 organization (about 128 Kb total) and uses a standard asynchronous SRAM interface.
Key points
- Organization: 16,384 words × 8 bits; 128 Kb.
- Interface: address inputs (A0–A13), data I/O (DQ0–DQ7), chip select (CS), output enable (OE), and write enable (WE); 3-state outputs.
- Speed and voltage: -7 indicates a 7 ns typical access time (tAA). Operates on a single supply (approximately 3.0–3.6 V; check the data sheet for exact ranges and conditions).
- Package: commonly a 28-pin TSOP/leadless style (code “TLI” relates to package type); check datasheet for the exact package.
- Features: non-volatile? No—it's volatile SRAM suitable for buffers, caches, frame buffers, and other fast random-access needs.
- Environment: typically specified for industrial temperature ranges (e.g., -40 to 85 °C).
For exact electrical specs, pinout, packaging, and timing, refer to the IS42S16400D-7TLI datasheet.

Here are the typical features of IS42S16400D-7TLI (per datasheet):
