IS42S83200L-7TL

Memory IC Overview

The IS42S83200L-7TL is a 256 Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by ISSI. It features an organization of 32 Megwords by 8 bits and operates with a maximum clock frequency of 143 MHz. The device utilizes a 54-pin TSOP II package with a 400 mil body width. Electrical specifications include an access time of 5.5 ns, a minimum supply voltage of 3 V, and a maximum supply voltage of 3.6 V. It supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Fully synchronous operation with all signals referenced to the positive edge of the system clock
• Internal bank architecture designed to hide row access/refresh cycles during active operations
• Supports fast page mode for efficient sequential data access within active banks

Memory IC Applications

• Embedded systems requiring high-density volatile memory
• Industrial control units operating in extended temperature environments
• Consumer electronics utilizing 3.3V logic interfaces

Memory IC Procurement Notes

Verify the specific suffix 'L' confirms the industrial temperature grade (-40°C to +85°C) rather than commercial variants. Ensure the '7' speed grade matches the required 143 MHz timing constraints for your design. Confirm the TSOP II package dimensions align with your PCB footprint requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a 256 Mbit density is required in a 54-pin surface-mount package. The L-series designation indicates suitability for harsher environmental conditions compared to standard commercial grades. Consider the 3.3V I/O compatibility if interfacing with legacy or specific microcontroller architectures that do not support lower voltage standards.

Memory IC Part Context

This part belongs to the IS42S83200 family of SDRAM devices from ISSI. These components are designed for general-purpose memory applications where moderate speed and high density are balanced. The TSOP II form factor offers a compact solution for space-constrained designs while maintaining reliable electrical performance across the specified industrial temperature range.

Memory IC Replacement Considerations

Check for IS42S83200L-7TLI which shares identical electrical characteristics but may differ in tape-and-reel packaging options. Verify pinout compatibility with other 54-pin TSOP II SDRAM parts from different manufacturers if sourcing alternatives.
