IS46R16160F-6BLA2

The IS46R16160F-6BLA2 is a 256-megabit DDR SDRAM from ISSI, Integrated Silicon Solution Inc, designed for applications requiring reliable high-speed memory in demanding thermal environments. With a 16M x 16 memory organization and DDR technology operating at 166MHz, this device delivers efficient data throughput while maintaining operational stability across an extended temperature range of -40°C to 105°C. This makes it an ideal choice for industrial, automotive-adjacent, and embedded systems where environmental resilience is critical.

Key Features

• DDR SDRAM Technology - Provides double data rate transfers at 166MHz clock frequency, enabling 333MT/s effective data rate for applications requiring fast memory access in a compact footprint.
• 256Mbit Capacity (16M x 16 Organization) - Offers 32MB of memory in a 16-bit wide parallel interface, balancing capacity and bandwidth for mid-range embedded designs without excessive power consumption.
• Extended Temperature Performance - Operates reliably from -40°C to 105°C ambient temperature, supporting deployment in harsh industrial environments, outdoor installations, and high-temperature enclosures.
• Compact 60-TFBGA Package - Housed in an 8mm x 13mm thin fine-pitch BGA package, minimizing board space while providing robust connections suitable for vibration-prone applications.
• Standard DDR Supply Voltage - Operates on 2.3V to 2.7V supply, compatible with standard DDR I/O voltage levels and simplifying integration into existing DDR-based system architectures.
• Fast Access and Write Cycle Times - Features 7ns access time and 15ns write cycle time, supporting responsive memory operations for real-time control systems and data acquisition applications.

Typical Applications

• Industrial Control Systems - This DDR SDRAM serves as main memory for programmable logic controllers (PLCs), human-machine interfaces (HMIs), and distributed control systems where the extended temperature rating ensures reliable operation in factory floor environments with variable climate control.
• Embedded Computing Platforms - The 256Mbit capacity and compact BGA footprint make this device suitable for single-board computers, industrial PCs, and edge computing nodes that require moderate memory density with proven DDR interface compatibility.
• Network and Telecommunications Equipment - The parallel DDR interface and fast access times support packet buffering and data processing in routers, switches, and base station controllers deployed in outdoor cabinets or temperature-variable facilities.
• Automotive Infotainment and Telematics - While not AEC-qualified, the -40°C to 105°C operating range positions this SDRAM for non-safety-critical automotive applications such as infotainment systems, navigation units, and telematics modules where extended thermal tolerance is beneficial.
• Medical and Test Equipment - Provides memory for diagnostic instruments, patient monitoring systems, and automated test equipment where stable performance across temperature variations and compact size support portable or enclosure-constrained designs.

Unique Advantages

• Reduced Thermal Management Complexity: The extended -40°C to 105°C rating allows system designers to deploy equipment in uncontrolled environments without active cooling, lowering BOM costs and improving long-term reliability.
• Proven DDR Interface Compatibility: Standard DDR SDRAM protocol ensures straightforward integration with a wide range of processors, FPGAs, and controllers, reducing design risk and accelerating time-to-market.
• Optimized Footprint for Space-Constrained Designs: The 60-pin TFBGA package in an 8mm x 13mm form factor provides high-density memory in minimal board space, critical for compact embedded systems and portable devices.
• Balanced Performance and Power Efficiency: 166MHz DDR operation delivers sufficient bandwidth for mid-range applications while maintaining lower power consumption compared to higher-speed DDR2 or DDR3 alternatives.
• Industrial-Grade Operational Resilience: Active lifecycle status from ISSI ensures continued availability for long product lifecycles typical in industrial and infrastructure applications.
• Simplified Supply Chain Management: Single-source 256Mbit DDR SDRAM with extended temperature spec consolidates memory sourcing and reduces the need to qualify multiple vendors for similar operating conditions.
