IS61VPS204836B-250M3L

Memory IC Overview

The IS61VPS204836B-250M3L is a 72 Mbit synchronous pipelined static random-access memory (SRAM) manufactured by ISSI. It features a memory organization of 2 Megawords by 36 bits and supports a maximum clock frequency of 250 MHz with a typical access time of 2.8 ns. The device utilizes a parallel interface and operates within a voltage range of 2.375 V to 2.625 V. It is housed in a 165-ball Fine Line Ball Grid Array (FBGA) package, suitable for surface-mount technology applications requiring high-speed data processing.

Memory IC Feature Summary

• Supports single-cycle deselect operations for efficient bus turnaround
• Features pipeline architecture for high-frequency data throughput
• Provides independent byte write control for flexible data masking

Memory IC Applications

• High-performance networking equipment
• Telecommunications infrastructure systems
• Industrial automation controllers

Memory IC Procurement Notes

Verify the specific suffix 'M3L' against official ISSI documentation to confirm the exact package type and temperature grade, as datasheets may list variations such as B3LI. Ensure compatibility with 2.5V I/O requirements and check for RoHS compliance status before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a wide 36-bit data path is required for high-bandwidth applications. The 250 MHz speed class offers significant performance advantages over lower-frequency variants. Consider the 165-ball FBGA footprint constraints during PCB layout design to ensure adequate thermal dissipation and signal integrity for the parallel interface.

Memory IC Part Context

This part belongs to the IS61VPS204836B series of synchronous SRAMs from ISSI. It shares architectural similarities with other members like the IS61VPS204836B-250B3LI but differs in packaging or environmental specifications. The series is designed for demanding embedded systems requiring fast, reliable memory access without the complexity of DRAM refresh cycles.

Memory IC Replacement Considerations

The IS61VPS204836B-250B3LI is a documented alternative within the same family. Verify pinout compatibility and electrical parameter alignment before substitution.
