AS4C8M16D1A-5TCNTR

The AS4C8M16D1A-5TCNTR from Alliance Memory is a 128-megabit synchronous dynamic random access memory (SDRAM) utilizing DDR (Double Data Rate) technology. Organized as 8M x 16, this parallel interface DRAM delivers a 200MHz clock frequency with 7ns access time, making it suitable for embedded systems, consumer electronics, and industrial applications requiring fast, cost-effective volatile memory. Operating from a 2.3V to 2.7V supply, this device offers a balance of performance and power efficiency in the standard 66-TSOP II package.

Key Features

• DDR SDRAM Architecture - Double data rate technology transfers data on both rising and falling clock edges, effectively doubling bandwidth compared to single data rate SDRAM at the same clock frequency.
• 128Mbit Capacity (8M x 16 Organization) - Provides 16 megabytes of volatile memory organized as 8 million words of 16 bits each, offering flexible addressing for various system architectures.
• 200MHz Clock Frequency - Operates at up to 200MHz clock rate with 7ns access time, delivering throughput suitable for real-time processing and buffering applications.
• Low Voltage Operation - 2.3V to 2.7V supply voltage reduces power consumption and heat generation compared to legacy 3.3V or 5V memory devices.
• Standard 66-TSOP II Package - Industry-standard 66-pin thin small outline package with 0.400" (10.16mm) width enables straightforward PCB layout and component sourcing.
• Commercial Temperature Range - 0°C to 70°C operating temperature suits mainstream commercial and consumer applications.

Typical Applications

• Consumer Electronics - This DDR SDRAM provides working memory for set-top boxes, digital televisions, and multimedia devices where the 128Mbit capacity handles buffering and application execution at a competitive price point.
• Embedded Computing Systems - The parallel interface and 200MHz operation support microcontrollers and processors in networking equipment, point-of-sale terminals, and industrial controllers that require deterministic memory access.
• Printer and Imaging Systems - The 8M x 16 organization efficiently stores raster data and page buffers in laser printers, copiers, and scanner systems where the 16-bit width aligns well with pixel processing pipelines.
• Telecommunications Equipment - This SDRAM serves as packet buffer memory in routers, switches, and base station controllers where the low-voltage operation contributes to overall system power budgets.
• Automotive Infotainment - Operating within the 0°C to 70°C range, this memory supports navigation systems, dashboard displays, and entertainment modules in passenger cabin environments.
