IS42S32800J-6BLI

Product Overview

The IS42S32800J-6BLI from ISSI, Integrated Silicon Solution Inc is a volatile DRAM memory integrated circuit based on SDRAM technology. It provides 256Mbit of memory organized as 8M x 32 and uses a parallel memory interface. The device operates from a 3V to 3.6V supply and is specified for a 166 MHz clock frequency with a 5.4 ns access time. It uses a 90-TFBGA (8x13) surface-mount package for board-mounted assembly.

Key Features

• 256Mbit volatile DRAM memory capacity
• 8M x 32 memory organization
• Parallel memory interface
• 166 MHz clock frequency
• 5.4 ns access time
• 3V to 3.6V supply voltage range
• -40°C to 85°C operating temperature range (TA)
• 90-TFBGA (8x13) surface-mount package

Applications

• Embedded processing systems that use parallel SDRAM as volatile working memory
• Data buffer subsystems requiring a 256Mbit parallel memory interface
• Controller platforms operating with a 3V to 3.6V memory supply

Design & Procurement Notes

When selecting the IS42S32800J-6BLI, confirm that the memory controller supports a parallel SDRAM interface, the 8M x 32 organization, and the 166 MHz clock frequency. The 5.4 ns access time should be evaluated within the system timing budget. The 3V to 3.6V supply range must match the system power architecture, and the -40°C to 85°C (TA) range should be checked against expected ambient conditions. Board layout should account for the 90-TFBGA (8x13) surface-mount footprint, including pad geometry and routing density. Because the device is volatile DRAM, system power must remain present for data retention.
