IS42S16800F-7TLI

Product Overview

The IS42S16800F-7TLI from ISSI, Integrated Silicon Solution Inc is a 128 Mbit SDRAM memory IC with a parallel interface and an 8M x 16 organization. It operates from a 3 V to 3.6 V supply and supports a 143 MHz clock frequency with a 5.4 ns access time. The device is packaged in a 54-TSOP II surface-mount package with a 0.400 inch, 10.16 mm width, and is specified for operation from -40°C to 85°C ambient temperature.

Key Features

• 128 Mbit volatile DRAM memory capacity

• 8M x 16 memory organization
• 143 MHz clock frequency
• 5.4 ns access time
• 3 V to 3.6 V supply voltage range
• -40°C to 85°C operating temperature range
• 54-TSOP II surface-mount package, 0.400 inch, 10.16 mm width

Applications

• Embedded controllers using external SDRAM as volatile working memory
• Data acquisition modules temporarily buffering sampled data before processing or transmission
• Communication terminals storing packet data while processing or forwarding
• Controller boards with 3.3 V logic and a parallel SDRAM memory bus

Design & Procurement Notes

Designers selecting the IS42S16800F-7TLI should confirm that the host memory controller supports a 128 Mbit SDRAM device organized as 8M x 16, a parallel bus, a 143 MHz clock, and a 5.4 ns access time. The 3 V to 3.6 V supply range and 54-TSOP II surface-mount footprint should also be checked against the board voltage, layout, and thermal design, with the -40°C to 85°C ambient range used as the operating envelope.
