IS61WV3216BLL-12TLI-TR

Memory IC Overview

The IS61WV3216BLL-12TLI-TR is a 512 Kbit asynchronous static random access memory (SRAM) manufactured by ISSI. It features a memory organization of 32K words by 16 bits, providing high-speed data access with a maximum access time of 12 nanoseconds. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports surface-mount installation in a 44-pin TSOP II package. It is designed for low-power applications, with a maximum operating current of 5 mA, and functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Asynchronous parallel interface for straightforward integration into standard digital systems
• Low power consumption characteristics suitable for battery-operated or energy-efficient designs
• Industrial temperature rating ensuring stable operation in demanding environmental conditions

Memory IC Applications

• Data buffering in embedded control systems
• Cache memory implementation in microprocessor architectures
• Storage for configuration data in industrial automation equipment

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing components. Confirm that the 12ns speed grade matches system timing requirements. Ensure the 3.3V nominal voltage aligns with the target board's power rails. Check RoHS compliance documentation if required for regulatory standards. Validate the 44-pin TSOP II footprint against the printed circuit board layout.

Memory IC Selection Notes

Select this component when a 16-bit wide memory interface is required at the 512 Kbit capacity level. The 12ns access time offers a balance between performance and power efficiency compared to faster or slower alternatives. Consider the TSOP II package for space-constrained surface-mount designs where through-hole options are unsuitable. Evaluate the 3.3V operating voltage against existing system logic levels to ensure compatibility without additional level shifting.

Memory IC Part Context

This part belongs to the IS61WV series of high-speed, low-power SRAMs from ISSI. The WV designation typically indicates wide-voltage or specific voltage range capabilities within the product line. The BLL suffix often denotes specific speed grades and package types within the broader family. This series is engineered for applications requiring non-volatile-like reliability with volatile memory speeds.

Memory IC Replacement Considerations

Direct pin-to-pin replacements may include other ISSI parts within the IS61WV3216BLL series with different speed grades or package options. Cross-manufacturer equivalents require careful verification of pinout, voltage tolerances, and access times. Always consult official datasheets for substitute parts to confirm functional compatibility.
