IS65WV25616DBLL-55CTLA3

Memory IC Overview

The IS65WV25616DBLL-55CTLA3 is a 4M-bit (256K x 16) asynchronous static RAM fabricated using high-performance CMOS technology. It operates on a single power supply ranging from 2.3V to 3.6V and features a 55 ns access time. The device supports industrial (-40°C to +85°C) and automotive (-40°C to +125°C) temperature ranges. It utilizes a 44-pin TSOP II package with TTL-compatible interface levels, three-state outputs, and independent upper/lower byte control.

Memory IC Feature Summary

Ultra-low power consumption with typical standby current of 6 µW
Fully static operation requiring no clock or refresh cycles
TTL-compatible interface levels for direct logic integration
Independent upper and lower byte data control

Memory IC Applications

Automotive electronic systems requiring extended temperature stability
Industrial embedded controllers needing low-power memory
Portable devices utilizing single-supply voltage architectures
High-speed data buffering in asynchronous communication interfaces

Memory IC Procurement Notes

Verify the specific suffix 'CTLA3' confirms the 44-pin TSOP II package, lead-free status, copper leadframe construction, and -40°C to +125°C automotive rating. Confirm the 55 ns speed grade matches system timing requirements. Ensure the 2.3V to 3.6V operating range aligns with the target power supply design.

Memory IC Selection Notes

Select this component when an asynchronous SRAM with wide voltage tolerance and extreme temperature capability is required. The 55 ns speed suits moderate-frequency applications where ultra-high speed is unnecessary. Consider the 44-pin TSOP II form factor for space-constrained PCB layouts compared to BGA options.

Memory IC Part Context

This part belongs to the IS65WV25616DxLL family of low-voltage, ultra-low power CMOS static RAMs. It shares architectural similarities with the IS62WV25616DALL but differs in its wider 2.3V-3.6V operating voltage range and enhanced automotive temperature ratings. The DBLL designation indicates the dual-voltage compatible variant within the series.
