IS42S16400J-6BL-TR

The IS42S16400J-6BL-TR is a 64-megabit synchronous dynamic random access memory (SDRAM) organized as 4M x 16 bits. Designed with standard SDRAM architecture and operating at up to 166MHz clock frequency, this memory IC delivers reliable performance for embedded systems requiring parallel memory interfaces. With a compact 54-pin TFBGA package measuring just 8x8mm, it offers an efficient solution for space-constrained applications running on 3.3V power rails.

Key Features

• Memory Configuration: 64Mbit capacity organized as 4 million words by 16 bits, providing flexible data width for parallel processing applications.
• Performance: 166MHz maximum clock frequency with 5.4ns access time enables responsive data transfers for real-time embedded applications.
• Power Supply: Single 3V to 3.6V supply voltage simplifies power management and reduces design complexity in 3.3V systems.
• Package: Ultra-compact 54-pin TFBGA in an 8x8mm footprint minimizes board space requirements while providing reliable ball grid array connectivity.
• Temperature Range: Operates across 0°C to 70°C commercial temperature range, suitable for standard indoor and controlled-environment applications.

Typical Applications

• Consumer Electronics: This SDRAM serves as main system memory in set-top boxes, digital cameras, and portable media players where the compact TFBGA package enables slim form factors while the 166MHz speed supports smooth video processing and menu navigation.
• Networking Equipment: Provides buffer memory for routers, switches, and network interface cards operating in controlled environments, where the 4M x 16 organization efficiently handles packet buffering and routing table storage.
• Office Equipment: Supports embedded controllers in printers, scanners, and multifunction devices where the commercial temperature range aligns with typical office conditions and the parallel interface simplifies integration with legacy architectures.
• Point-of-Sale Terminals: Delivers system memory for POS systems and payment terminals in retail environments, where the commercial-grade specifications meet operational requirements while the compact package fits space-limited terminal designs.

Unique Advantages

• Space-Efficient Footprint: The 8x8mm TFBGA package delivers 64Mbit capacity in minimal board area, enabling higher memory density without expanding PCB dimensions.
• Standard SDRAM Interface: Compatible with widely-supported parallel SDRAM controllers, reducing development time and leveraging established driver ecosystems.
• Single Voltage Operation: Eliminates the need for multiple power rails, simplifying power supply design and reducing BOM count.
• Proven SDRAM Architecture: Mature technology with well-understood timing characteristics and extensive application notes, lowering integration risk for new designs.
• Compact Ball Grid Array: BGA construction provides superior electrical performance and thermal characteristics compared to leaded packages of similar size.
