Memory IC datasheet and documents for IS66WV51216DBLL-70TLI

IS66WV51216DBLL-70TLI

Memory IC Overview

The IS66WV51216DBLL-70TLI is an 8M bit pseudo static RAM organized as 512K words by 16 bits. It features a 70 ns access time and operates on a single power supply ranging from 2.5 V to 3.6 V. The device utilizes three-state outputs with independent upper and lower byte data control. It supports industrial temperature operation from -40°C to +85°C and is housed in a 44-pin TSOP II package.

Memory IC Feature Summary

CMOS low power operation with standby current reduction capabilities
Independent upper and lower byte data control for flexible memory access
On-chip voltage sensor for automatic power-up initialization

Memory IC Applications

Industrial embedded systems requiring high-speed volatile storage
Automotive electronics operating within specified temperature ranges
Consumer devices utilizing parallel interface memory expansion

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type, as the datasheet lists distinct part numbers for TSOP-II and mini BGA configurations. Confirm that the voltage range aligns with the DBLL designation (2.5V-3.6V) rather than the DALL variant. Ensure compliance with RoHS standards and check for any automotive qualification requirements if deploying in A1 or A2 rated environments.

Memory IC Selection Notes

Select this component when a 70 ns access speed is sufficient for the system architecture. Consider alternative speeds like 55 ns if higher performance is needed, or verify compatibility with the 1.7V-1.95V DALL series if lower voltage operation is mandatory. Ensure the design accommodates the 44-pin TSOP II footprint and manages the refresh cycles inherent to pseudo SRAM technology.

Memory IC Part Context

This device belongs to the IS66/67WV51216 family of ultra-low power pseudo CMOS static RAMs manufactured by ISSI. The family includes variants with different access times and voltage specifications, packaged in either 44-pin TSOP II or 48-ball mini BGA formats. The DBLL suffix specifically denotes the industrial temperature range and the 2.5V-3.6V operating voltage window.
