Memory IC datasheet and documents for IS66WV51216DBLL-70TLI-TR

IS66WV51216DBLL-70TLI-TR

Memory IC Overview

The ISSI IS66WV51216DBLL-70TLI-TR is an 8Mbit pseudo-static CMOS RAM organized as 512K words by 16 bits. It operates on a single 2.5V to 3.6V power supply with a 70ns access time. The device features three-state outputs, upper and lower byte data control, and industrial temperature range availability (-40°C to +85°C). Packaged in a 44-pin TSOP Type II, it utilizes high-performance CMOS technology for low power consumption.

Memory IC Feature Summary

High-speed asynchronous operation with 70ns access time
Low power CMOS architecture with dedicated standby modes
Independent upper and lower byte control for flexible data handling
TTL-compatible inputs and three-state outputs

Memory IC Applications

Embedded system memory expansion
Industrial automation data buffering
Consumer electronics cache storage

Memory IC Procurement Notes

Verify the specific suffix 'TLI' confirms the 44-pin TSOP package and lead-free status. Confirm the '-TR' designation matches the required reel packaging quantity of 2500 units. Ensure the voltage range aligns with the 2.5V to 3.6V specification for the DBLL variant.

Memory IC Selection Notes

Select this component when a 512K x 16 organization is required within a standard TSOP footprint. The 70ns speed grade suits general-purpose embedded applications. Verify that the 2.5V to 3.6V operating voltage matches the target system's power rails before finalizing the design.

Memory IC Part Context

This part belongs to the IS66/67WV51216 family of pseudo-static RAMs. It shares architectural similarities with the DALL variant but differs in its specified operating voltage range. The DBLL series is designed for industrial environments requiring reliable performance across wide temperature variations.
