Description

IS42S32200L-7TL is a high-speed static RAM (SRAM) from the IS42S family. It provides fast, volatile storage with a parallel data interface, suitable for caches, buffers, and look-up tables in embedded systems.
Key points:
- Type: asynchronous CMOS SRAM (no refreshing required).
- Interface: bidirectional data I/O (DQ), with address lines (A0…An) and control pins: Chip Enable (CE), Output Enable (OE), and Write Enable (WE).
- Speed/Package: the “-7” indicates a 7 ns speed grade; “TL” typically denotes a lead-free/industrial-temperature variant (check datasheet for exact packaging and temperature range).
- Power: intended for CMOS operation at a typical single supply (exact voltage per variant).
- Applications: fast random-access memory for caches, buffers, frame buffers, and similar workloads.
Note: exact memory organization (width × depth), voltage, packaging, and timing are variant-specific. Refer to the official datasheet for your lot to confirm density, pinout, and electrical characteristics.

Features

Key features of IS42S32200L-7TL (typical, from datasheet):
- Type/Density: 256 Mb static RAM (32M x 8)
- Speed: -7 ns access time
- Voltage: 3.3 V operation (typ. 2.7–3.6 V)
- Interface: Asynchronous CMOS SRAM with CS#, WE#, OE#; LB# and UB# for lower/upper byte enables
- Packaging/Lead status: Pb-free (L), -TL option typically for Tape & Reel packaging
- Temperature: Commercial and Industrial (-40°C to 85°C)
- Other: No refresh required (static RAM), suitable for fast buffers, caches, and frame buffers
Note: Check the exact packaging and temperature options in the specific datasheet revision for your order, as these can vary by revision and lot.
