Built on proven SDRAM technology with a 143MHz clock frequency and 5.4ns access time, this memory IC provides the balance of speed and capacity needed for data-intensive applications. Housed in a compact 54-TFBGA package and qualified for -40°C to 85°C operation, it serves industrial automation, communications infrastructure, and embedded computing where temperature extremes demand robust components.

Key Features

• 512Mbit Capacity - Organized as 32M x 16, providing ample memory for buffering, frame storage, and data processing tasks in embedded designs.
• 143MHz Clock Frequency - Supports high-speed data transfer with 5.4ns access time, enabling responsive system performance.
• Extended Temperature Range - Qualified for -40°C to 85°C ambient operation, ensuring reliable memory retention and data integrity in industrial and outdoor environments.
• Parallel Interface - Standard SDRAM parallel interface simplifies integration with processors, FPGAs, and controllers using established memory protocols.
• 3V to 3.6V Operation - Compatible with common 3.3V system power rails, reducing the need for additional voltage regulation.
• Compact 54-TFBGA Package - 8mm x 13mm thin fine-pitch ball grid array footprint conserves PCB space in size-constrained designs.

Typical Applications

• Industrial Automation - This SDRAM provides reliable memory for PLCs, HMIs, and motion controllers where extended temperature tolerance ensures consistent operation in factory floor environments and the parallel interface integrates seamlessly with industrial processor architectures.
• Communications Infrastructure - Used in routers, switches, and base stations for packet buffering and data forwarding, where the 512Mbit capacity handles burst traffic and the temperature rating supports outdoor installations.
• Embedded Computing - Serves as main memory or display buffer in embedded systems including medical devices, test equipment, and point-of-sale terminals, where the compact BGA package fits space-limited designs.
• Automotive Infotainment - Suitable for non-safety-critical automotive applications such as dashboard displays and entertainment systems, where the extended temperature range accommodates in-cabin temperature variations.
• Network Attached Storage - Functions as cache memory in NAS devices and storage controllers, where the 143MHz clock frequency accelerates data transfers between storage media and network interfaces.

Unique Advantages

• Proven SDRAM Technology: Mature and widely-supported memory architecture reduces integration risk and leverages existing software libraries and drivers.
• Single 3.3V Power Rail: Eliminates the need for multiple voltage regulators, simplifying power supply design and reducing BOM cost.
