IS62WVS1288FBLL-20NLI

Memory IC Overview

The IS62WVS1288FBLL-20NLI is a 1 Mbit (128K x 8) serial static random access memory manufactured by ISSI. It utilizes CMOS technology to support a maximum clock frequency of 20 MHz with a typical access time of 25 ns. The device operates within a voltage range of 2.2 V to 3.6 V and features a low maximum supply current of 8 mA. It is housed in an 8-pin SOIC package, supports SMD/SMT installation, and functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports standard SPI, QPI, and SQI serial interfaces for reduced pin count
• Provides low power consumption with standby current as low as 4 µA
• Fabricated using high-performance CMOS technology for reliable operation

Memory IC Applications

• Industrial control systems requiring low signal count memory
• Automotive electronics operating in extended temperature environments
• Portable devices utilizing battery power due to low standby current

Memory IC Procurement Notes

Verify the specific suffix NLI against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with required interface protocols such as SPI or QPI. Confirm that the 20 MHz clock speed meets system timing requirements. Check for RoHS compliance status if environmental regulations apply to the target assembly process.

Memory IC Selection Notes

Select this component when a small footprint and minimal I/O pins are critical for the design. The 20 MHz speed offers a balance between performance and power efficiency for moderate data rates. Consider the 8-pin SOIC package for ease of automated placement. Verify that the 2.2V to 3.6V supply range aligns with the system's available voltage rails.

Memory IC Part Context

This part belongs to the IS62WVS series of serial SRAMs from ISSI. These devices integrate DRAM arrays with self-refresh capabilities to provide non-volatile-like behavior without the complexity of flash programming. The series is designed to replace parallel SRAMs in applications where board space and pin counts are constrained.

Memory IC Replacement Considerations

Direct replacements include other parts within the IS62WVS family, such as the IS62WVS0648FBLL-20NLI for smaller capacity needs. Cross-reference pinouts and electrical characteristics carefully, as interface protocols may vary between different sub-series.
