IS66WVO8M8DALL-200BLI-TR

Memory IC Overview

The IS66WVO8M8DALL-200BLI-TR is a 64 Mbit OctalRAM pseudo SRAM manufactured by ISSI. It features an 8 M x 8 organization with SPI serial interface and supports clock frequencies up to 200 MHz. The device operates within a voltage range of 1.7 V to 1.95 V and functions between -40°C and +85°C. Packaged in a 24-ball TFBGA, it offers high-speed data transfer capabilities suitable for space-constrained embedded applications requiring non-volatile-like performance without the complexity of flash controllers.

Memory IC Feature Summary

• Octal I/O architecture enables high-bandwidth serial data access
• Pseudo SRAM technology provides SRAM-like speed with DRAM density
• Integrated controller simplifies system design by removing external logic

Memory IC Applications

• Portable consumer electronics requiring compact memory solutions
• Industrial control systems needing fast boot times
• Automotive infotainment displays

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the voltage variant matches the target system's power rails, as other versions exist at different voltages. Check RoHS compliance status for environmental regulations. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Validate lead times with authorized distributors as availability may fluctuate.

Memory IC Selection Notes

Select this component when system designers require high-speed serial access to 64 Mbits of memory in a small footprint. It serves as a drop-in replacement for parallel PSRAM where pin count reduction is critical. Consider the 1.8V operating voltage against available board power supplies. Evaluate thermal requirements for the TFBGA package in enclosed enclosures.

Memory IC Part Context

This part belongs to ISSI's OctalRAM family, designed to bridge the gap between parallel SRAM and serial NOR Flash. It utilizes a proprietary serial interface that mimics standard SPI protocols but allows for higher throughput through eight data lines. The family targets applications demanding rapid code execution from memory.

Memory IC Replacement Considerations

Direct substitutes include the IS66WVO8M8FBLL-166BLI for lower frequency needs or the IS66WVQ16M4 series for quad-interface alternatives. Verify pin compatibility and voltage levels before swapping. Cross-reference datasheets for timing parameter differences.
