IS42S16400J-7BLI-TR

The IS42S16400J-7BLI-TR is a 64-megabit synchronous dynamic random-access memory (SDRAM) organized as 4M x 16 bits. This parallel interface DRAM operates at clock frequencies up to 143MHz with a 5.4ns access time, making it suitable for embedded systems requiring cost-effective volatile memory with moderate performance requirements. The compact 54-TFBGA package (8x8mm) provides space-efficient integration for designs with limited board area.

Key Features

• Memory Architecture - 64Mbit capacity organized as 4M x 16-bit words, providing flexible data path widths for various system architectures.
• Performance - 143MHz clock frequency with 5.4ns access time delivers sufficient bandwidth for control systems, data logging, and buffering applications.
• Power Supply - Single 3V to 3.6V supply voltage simplifies power distribution and enables compatibility with standard 3.3V logic systems.
• Package - 54-pin TFBGA in an 8x8mm footprint minimizes board space while maintaining good thermal characteristics and manufacturability.
• Temperature Range - Industrial-grade -40°C to 85°C ambient temperature range supports deployment in challenging environmental conditions.
• Interface - Standard parallel SDRAM interface with familiar command structure and timing parameters for straightforward system integration.

Typical Applications

• Embedded Controllers - This SDRAM serves as program execution memory and data buffer space in microcontroller-based systems where the 4M x 16 organization matches common embedded processor bus widths.
• Data Acquisition Systems - The 64Mbit capacity provides sufficient buffering for sensor data collection and temporary storage before transfer to non-volatile memory or network interfaces.
• Industrial HMI Displays - Frame buffering and graphics data storage for human-machine interfaces benefit from the parallel access capability and industrial temperature tolerance.
• Communication Equipment - Packet buffering and protocol processing in network switches, routers, and telecommunications gear utilize the moderate bandwidth and cost-effective memory density.
• Test and Measurement Instruments - Waveform capture and signal processing applications leverage the synchronous operation for predictable data capture timing.

Unique Advantages

• Compact Footprint: The 8x8mm TFBGA package delivers higher density than TSOP alternatives, reducing PCB area requirements and enabling smaller product form factors.
• Standard SDRAM Interface: Familiar command structure and timing parameters reduce development time and leverage existing controller IP and software drivers.
• Industrial Temperature Support: The -40°C to 85°C operating range eliminates the need for environmental conditioning in many industrial installations, reducing system cost and complexity.
• 3.3V Single Supply: Compatibility with standard logic voltage levels simplifies power supply design and enables direct interfacing with most embedded processors without level translation.
• Cost-Effective Volatile Memory: SDRAM technology provides lower cost per bit than SRAM for applications where data retention during power-off is not required.
• Moderate Performance Sweet Spot: The 143MHz clock rate balances bandwidth requirements with power consumption and signal integrity considerations for typical embedded applications.
