IS42S16800J-7BLI

Memory IC Overview

The IS42S16800J-7BLI is a 128 Mbit Synchronous DRAM manufactured by ISSI. It features an 8M x 16 organization with a maximum clock frequency of 143 MHz and a typical access time of 5.4 ns. The device operates within a voltage range of 3 V to 3.6 V and supports temperatures from -40°C to +85°C. It utilizes a 54-ball BGA package measuring 8 mm x 8 mm.

Memory IC Feature Summary

• Fully synchronous operation with all signals referenced to the positive clock edge
• Internal bank architecture for hiding row access and precharge operations
• Programmable burst lengths including sequential and interleave sequences

Memory IC Applications

• Mobile communication devices
• Personal digital assistants
• Laptop computers
• Consumer electronics

Memory IC Procurement Notes

Verify the specific suffix 'J' against official datasheets to confirm it denotes the commercial temperature grade (-40°C to +85°C) rather than industrial or extended ranges. Ensure the 'BLI' suffix corresponds to the lead-free TFBGA-54 package configuration. Confirm RoHS compliance status directly with the manufacturer documentation before procurement.

Memory IC Selection Notes

Select this component when a 128 Mbit density with an 8M x 16 data width is required. The 143 MHz speed class suits applications needing moderate bandwidth. Verify that the system design accommodates the 3.3V I/O levels and the specific 54-ball BGA footprint constraints during PCB layout.

Memory IC Part Context

This part belongs to the IS42S16800 series of SDRAMs, which are designed for high-performance mobile and consumer applications. The series typically includes variants with different speed grades and package options, sharing common internal architectures while differing in electrical timing and physical form factors.

Memory IC Replacement Considerations

Check for IS42S16800E-7BLI as a potential alternative within the same family. Verify pinout compatibility and electrical parameter alignment before substitution.
