Memory IC datasheet and documents for IS66WV25616BLL-55TLI

IS66WV25616BLL-55TLI

Memory IC Overview

The IS66WV25616BLL-55TLI is a 4Mbit pseudo static RAM organized as 256K words by 16 bits. It features a 55ns access time and operates on a single 2.5V to 3.6V power supply. The device utilizes CMOS technology for low power consumption, offering typical standby currents in the microampere range. It includes three-state outputs, upper and lower byte data control, and industrial temperature availability. The component is housed in a 44-pin TSOP (Type II) package.

Memory IC Feature Summary

CMOS low power operation with reduced standby dissipation
Three-state outputs for bus compatibility
Independent upper and lower byte data control
Industrial temperature range availability

Memory IC Applications

High-speed data buffering
Cache memory systems
Embedded storage applications

Memory IC Procurement Notes

Verify the specific suffix TLI confirms the 44-pin TSOP Type II package configuration. Confirm the BLL designation aligns with the required 2.5V to 3.6V operating voltage range. Ensure the 55ns speed grade matches system timing requirements. Check for lead-free compliance status if environmental regulations apply to the assembly process.

Memory IC Selection Notes

Select this component when a 16-bit wide asynchronous interface is required within a compact surface-mount footprint. The 44-pin TSOP package suits designs where BGA options are unsuitable. Verify that the 2.5V to 3.6V supply voltage matches the target system logic levels. Consider the low standby current benefits for battery-powered or power-sensitive portable devices.

Memory IC Part Context

This part belongs to the IS66WV25616 series of low voltage, ultra-low power pseudo CMOS static RAMs from ISSI. The series offers variations in speed grades and packages, including mini BGA options. The BLL variant specifically targets the 2.5V to 3.6V voltage domain, distinguishing it from the ALL series designed for lower voltage operations.
