IS42S16400J-6TL

Product Overview

The IS42S16400J-6TL from ISSI, Integrated Silicon Solution Inc, is a 64 Mbit SDRAM memory integrated circuit with a 4M x 16 organization and a parallel memory interface. It operates from a 3 V to 3.6 V supply and supports a 166 MHz clock frequency, with a 5.4 ns access time. The device is packaged in a 54-TSOP II surface-mount package and is specified for operation from 0°C to 70°C ambient temperature.

Key Features

• 64 Mbit DRAM capacity organized as 4M x 16
• Volatile SDRAM memory technology
• Parallel memory interface
• 166 MHz clock frequency
• 5.4 ns access time
• 3 V to 3.6 V supply voltage
• 0°C to 70°C ambient operating range
• 54-TSOP II surface-mount package

Applications

• Embedded controller systems using a parallel memory bus for program or working data storage.
• Electronic assemblies requiring a 16-bit wide volatile memory device.
• Microprocessor-based boards where 64 Mbit SDRAM can serve as main memory.
• Communications equipment using parallel SDRAM for temporary data buffering.

Design & Procurement Notes

Designers should verify that the host controller supports a parallel SDRAM interface, the 4M x 16 organization, 166 MHz timing, and 3 V to 3.6 V supply levels. The 0°C to 70°C ambient operating range should be considered for placement near heat sources. The 54-TSOP II package requires surface-mount assembly and board layout compatible with the 10.16 mm wide body. Because the memory is volatile, the system must account for data loss during power removal. Signal integrity and pin mapping should be reviewed against the parallel bus requirements.
