Key Features

• Core Memory Architecture - 256Mbit total capacity organized as 32M x 8, providing flexible byte-wide data access for embedded processor and controller applications.
• DDR1 SDRAM Technology - Double Data Rate synchronous DRAM transfers data on both rising and falling clock edges at 200MHz, doubling effective bandwidth compared to conventional SDRAM.
• Fast Access Performance - 0.7ns access time and 15ns write cycle time ensure responsive memory operations for real-time embedded applications.
• Power Supply - Operates from 2.3V to 2.7V supply voltage, compatible with standard 2.5V logic families and reducing overall system power consumption.
• Commercial Temperature Range - Rated for 0°C to 70°C ambient operation, suitable for office, commercial, and controlled industrial environments.
• Standard Package - 66-pin TSOP II package with 10.16mm body width provides industry-standard footprint for straightforward PCB layout and sourcing.

Typical Applications

• Embedded Computing - This DDR1 SDRAM serves as main system memory in embedded controllers and single-board computers where its 256Mbit capacity and byte-wide organization match the requirements of 8-bit and 16-bit processor architectures.
• Network Equipment - The device provides packet buffer memory for switches and routers operating in controlled environments, where the 200MHz clock frequency supports wire-speed processing of moderate network traffic loads.
• Office Automation - Printers, copiers, and document scanners utilize this memory for image buffering and processing tasks, benefiting from the DDR1 bandwidth for handling document data flows in commercial office settings.
• Point-of-Sale Systems - Retail terminals and kiosks leverage this SDRAM for transaction processing and user interface operations in temperature-controlled retail environments.
• Test and Measurement Instruments - Benchtop and portable test equipment uses this memory for data acquisition buffering and waveform storage in laboratory and field service applications within the commercial temperature range.

Unique Advantages

• Standard DDR1 Interface: Uses industry-standard DDR1 protocol and pinout, enabling straightforward integration with established memory controller IP and reducing validation effort.
• Byte-Wide Organization: The 32M x 8 configuration matches 8-bit and 16-bit bus architectures without requiring additional glue logic, simplifying board design.
• Proven Technology Platform: DDR1 SDRAM represents a mature, well-understood technology with extensive design resources and support ecosystem available.
• Cost-Effective Capacity: 256Mbit density hits the sweet spot for many embedded applications that require more than SRAM can economically provide but don't need the complexity of higher-density DDR2 or DDR3.
• Low Voltage Operation: 2.5V nominal supply reduces power consumption compared to legacy 3.3V memories while maintaining compatibility with common embedded voltage rails.
• Commercial Temperature Rating: Operating range of 0°C to 70°C matches the thermal environment of most commercial and office equipment, avoiding the cost premium of extended temperature variants.
