Descripción general

Description

IS42S32800J-7BLI is a high-density memory IC from ISSI (Integrated Silicon Solution, Inc.). It is a 32M x 8-bit memory device (256 Mbit total) designed for synchronous operation. The -7 indicates a 7 ns speed grade, suitable for fast access applications. It is offered in a Pb-free BLI leadless package, typically operating around 3.3 V, and is intended for systems that use a memory controller to manage synchronized reads/writes, bursts, and auto-precharge. Common use cases include embedded systems, graphics, networking, and telecom equipment requiring moderate-density, high-speed RAM. For exact electrical characteristics, timing, commanded sequences, and packaging details, refer to the official ISSI datasheet for IS42S32800J-7BLI.

Features

Here are the likely features of IS42S32800J-7BLI (SDRAM):
- Capacity/organization: 256 Mb total (32M × 8)
- Type: Synchronous DRAM (SDRAM)
- I/O width: x8 data bus
- Voltage: 3.3V (typical)
- Speed grade: -7 (up to ~143 MHz clock)
- Organization: multi-bank (typically 4 banks)
