IS42S32800L-6BL

The IS42S32800L-6BL is a 256Mbit synchronous DRAM from ISSI, Integrated Silicon Solution Inc, designed for embedded systems requiring reliable parallel memory access. Organized as 8M x 32, this SDRAM operates at clock frequencies up to 166MHz with a 5.4ns access time, making it well-suited for microcontroller-based designs, industrial controllers, and consumer electronics where fast, cost-effective volatile memory is essential.

Key Features

• Memory Architecture - 256Mbit total capacity organized as 8M x 32, providing flexible addressing for 32-bit data bus applications and enabling efficient memory utilization in embedded designs.
• Performance - 166MHz clock frequency with 5.4ns access time delivers responsive read/write operations for real-time control systems and data buffering applications.
• Power Supply - Single 3V to 3.6V supply voltage simplifies power design and integrates seamlessly with standard 3.3V logic systems.
• Interface - LVTTL-compatible parallel interface ensures straightforward integration with microprocessors, FPGAs, and microcontrollers without level translation.
• Package - 90-pin TFBGA (8mm x 13mm) offers a compact footprint for space-constrained PCB layouts while maintaining reliable ball grid array connections.
• Temperature Range - Commercial temperature range of 0°C to 70°C (TA) supports standard operating environments in office, retail, and consumer equipment.

Typical Applications

• Embedded Computing Systems - This SDRAM serves as main memory or frame buffer in embedded processors running real-time operating systems, where the 256Mbit capacity and 166MHz performance support moderate data processing workloads.
• Consumer Electronics - Ideal for set-top boxes, digital displays, and home appliances that require temporary data storage during operation, where the commercial temperature range and 3.3V supply align with standard consumer product requirements.
• Industrial Controllers - Provides reliable volatile memory for PLCs, HMI panels, and automation equipment operating within controlled environments, where the parallel LVTTL interface simplifies integration with industrial microcontrollers.
• Networking Equipment - Functions as packet buffer memory in switches, routers, and communication modules requiring fast read/write cycles for data queuing and temporary storage.
• Point-of-Sale Terminals - Supports transaction processing and display buffering in retail terminals where moderate memory capacity and standard operating temperature are sufficient for typical commercial settings.

Unique Advantages

• Simplified Power Management: Single 3.3V supply voltage eliminates the need for multiple voltage rails, reducing BOM costs and simplifying power distribution across the PCB.
• Space-Efficient Design: The 90-TFBGA package provides 256Mbit capacity in an 8mm x 13mm footprint, enabling higher memory density in compact product enclosures.
• Direct Logic Compatibility: LVTTL interface allows connection to standard 3.3V logic without additional level shifters or translation circuits, reducing design complexity and component count.
• Proven SDRAM Architecture: Synchronous operation with clock-synchronized data transfers simplifies timing design compared to asynchronous DRAM, improving system reliability and reducing debug time.
• Standard Commercial Availability: Active lifecycle status ensures ongoing supply for new designs and product revisions without concerns about obsolescence during typical product lifecycles.
• Cost-Effective Volatile Memory: SDRAM technology delivers competitive pricing for applications requiring temporary data storage, buffer memory, or working RAM where non-volatility is not required.
