IS62WV6416ALL-55BLI-TR

Memory IC Overview

The IS62WV6416ALL-55BLI-TR is a 1Mbit (64K x 16) asynchronous static RAM manufactured by ISSI. It operates on a single power supply ranging from 1.7V to 2.2V and features a 55ns access time. The device utilizes a 48-pin mini BGA package measuring 6mm by 8mm. It supports industrial temperature ranges from -40°C to +85°C and includes TTL-compatible interface levels with three-state outputs.

Memory IC Feature Summary

• Ultra-low power CMOS technology providing low operating current and microamp-level standby consumption.
• Fully static operation requiring no clock or refresh cycles for data retention.
• Independent upper and lower byte control via dedicated UB and LB pins.

Memory IC Applications

• Embedded memory systems in industrial controllers
• Data buffering in telecommunications equipment
• Cache memory in consumer electronics

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm voltage range, speed grade, and lead-free status. Confirm that the reel packaging matches the required tape-and-reel specifications for automated assembly processes.

Memory IC Selection Notes

Select this component when a 1.7V to 2.2V supply voltage is required alongside a compact 48-pin mini BGA footprint. Ensure the system design accommodates the specified industrial temperature range and utilizes the appropriate pull-up or termination resistors for the parallel interface.

Memory IC Part Context

This part belongs to the IS62WV6416 series of low-voltage static random-access memories. It shares architectural similarities with the IS62WV6416BLL but differs in its optimized operating voltage range. The series is designed for applications demanding high-speed data access with minimal power consumption.

Memory IC FAQ

What is the function of the CS2 pin?

CS2 serves as an additional chip enable input. When configured for the standard option, it remains unconnected; however, a 2-CS option variant exists where both CS1 and CS2 must be active for selection.

How does the device handle data retention?

The device enters a data retention mode when VDD drops below the operating threshold but remains above 1.2V, provided the chip select inputs are held in their deselected states.
