IS45S32200E-7BLA1

Memory IC Overview

The IS45S32200E is a 64Mb Synchronous DRAM organized as 512K bits x 32 bits x 4 banks. It operates on a single 3.3V power supply with an L VTTL interface. The device supports clock frequencies of 200, 166, 143, and 133 MHz. Key timing parameters include access times ranging from 5 to 8 ns depending on CAS latency and speed grade. Available packages include 86-pin TSOP-II and 90-ball TF-BGA.

Memory IC Feature Summary

• Fully synchronous operation with all signals referenced to the positive clock edge
• Internal bank architecture for hiding row access and precharge cycles
• Programmable burst lengths including sequential and interleave sequences
• Self-refresh modes for data retention without external clocking

Memory IC Applications

• Automotive electronics systems
• Industrial control applications
• Commercial embedded memory systems

Memory IC Procurement Notes

Verify the specific speed grade suffix (e.g., -7) against the required clock frequency and access time specifications. Confirm the package type matches the design footprint. Ensure the operating temperature range aligns with the target application environment. Check for RoHS compliance status before finalizing orders.

Memory IC Selection Notes

Select based on the required system clock frequency and available timing margins. Choose between TSOP-II and BGA packages according to board space constraints. Verify that the 3.3V supply voltage is compatible with the host controller logic levels. Consider the CAS latency requirements for the specific data throughput needs.

Memory IC Part Context

This component belongs to the IS42/45S32200E family of 64Mb SDRAMs manufactured by ISSI. The 'IS45' designation indicates automotive-grade qualification options alongside commercial and industrial variants. It utilizes a pipeline architecture to achieve high-speed data transfer rates within standard memory subsystems.

Memory IC Replacement Considerations

Direct replacements include the IS42S32200E for commercial grades or other ISSI parts within the same 64Mb SDRAM family sharing identical pinouts and electrical characteristics.
