IS46R16160F-6TLA2-TR

The IS46R16160F-6TLA2-TR is a 256Mbit DDR SDRAM memory IC from ISSI, Integrated Silicon Solution Inc. Organized as 16M x 16, this parallel interface DRAM operates at 166MHz with 7ns access time, making it well-suited for applications requiring high-speed data access in compact form factors. With an extended industrial temperature range of -40°C to 105°C, this memory solution delivers reliable performance in demanding environments where standard commercial-grade components may not suffice.

Key Features

• High-Density Memory Architecture - 256Mbit capacity with 16M x 16 organization provides substantial data storage in a single package, reducing board space requirements and simplifying memory subsystem design.
• DDR SDRAM Technology - Double Data Rate architecture transfers data on both rising and falling clock edges, effectively doubling bandwidth compared to conventional SDRAM while maintaining similar power consumption.
• Fast Clock Operation - 166MHz clock frequency with 7ns access time ensures rapid data retrieval for time-critical applications requiring low latency memory access.
• Extended Temperature Range - Operating range of -40°C to 105°C (TA) supports deployment in industrial environments, outdoor installations, and automotive applications where temperature extremes are common.
• Standard Voltage Operation - 2.3V to 2.7V supply voltage range provides compatibility with common 2.5V digital logic families while allowing some margin for voltage variation.
• Compact 66-TSOP II Package - 66-pin TSOP II (0.400", 10.16mm width) surface-mount package offers a balance between pin count, board footprint, and thermal performance for space-constrained designs.

Typical Applications

• Industrial Control Systems - This DDR SDRAM provides working memory for industrial PLCs, motion controllers, and process automation equipment where the extended temperature range ensures reliable operation in factory floor environments without additional thermal management.
• Automotive Infotainment - The memory IC serves as frame buffer and data cache in automotive dashboard displays, navigation systems, and rear-seat entertainment units where the wide temperature tolerance accommodates in-cabin and under-hood mounting locations.
• Networking and Telecommunications Equipment - This device functions as packet buffer memory in routers, switches, and base station controllers where the fast access time and DDR architecture support line-rate packet processing at moderate data rates.
• Medical Instrumentation - The SDRAM provides data acquisition buffer memory in diagnostic equipment and patient monitoring systems where extended temperature capability allows operation in non-climate-controlled environments and mobile medical units.
• Embedded Computing Platforms - This memory IC serves as system RAM in single-board computers, embedded controllers, and edge computing devices where the parallel interface simplifies integration with microprocessors and FPGAs lacking native DDR2/DDR3 controllers.

Unique Advantages

• Simplified Design Integration: The parallel DDR interface eliminates the complexity of high-speed serial memory protocols, reducing EMI concerns and simplifying PCB layout for designs migrating from legacy SDRAM.
• Extended Lifecycle Support: Active lifecycle status ensures ongoing availability for long-production-life industrial and automotive platforms where component discontinuation poses significant redesign risk.
• Reduced Component Count: The 256Mbit single-chip solution eliminates the need for multiple smaller memory devices, reducing BOM complexity, board space requirements, and assembly costs.
• Temperature-Stable Performance: Industrial-grade temperature qualification enables consistent access timing and data retention across the full operating range without derating or performance degradation.
• Cost-Effective Solution: DDR SDRAM technology provides a balance between performance and cost for applications that require more bandwidth than conventional SDRAM but do not justify the complexity of DDR2 or DDR3 memory subsystems.
• Proven Technology Platform: Mature DDR SDRAM technology offers well-understood electrical characteristics, established controller IP, and extensive software support, reducing development risk compared to newer memory architectures.
