The UPD431000ACZ-85LL is a high-speed 1Mbit (128K x 8) CMOS Static RAM (SRAM) manufactured by NEC (now Renesas Electronics). It's designed for applications demanding fast access times and low power consumption. This SRAM is commonly used in memory caches, embedded systems, and other high-performance digital circuits.

Applications:

• Cache memory
• Embedded systems
• Networking equipment
• Industrial control systems
• High-performance computing

Features:

• High-speed access time: 85ns
• Low power consumption
• Single 5V power supply
• Fully static operation (no clock required)
• TTL compatible inputs and outputs
• 128K x 8-bit organization

Benefits:

• Fast Data Access: The 85ns access time enables rapid data retrieval, improving overall system performance.
• Reduced Power Consumption: The CMOS design minimizes power dissipation, making it suitable for battery-powered or energy-sensitive applications.
• Simplified System Integration: The single 5V power supply and TTL compatibility simplify integration with other digital components.
• Easy to Use: Fully static operation eliminates the need for complex timing control, simplifying the design process.

Specifications:

The UPD431000ACZ-85LL operates on a single 5V power supply and features a typical operating current of around 90mA. It has an operating temperature range of 0°C to 70°C. The device is available in a 32-pin DIP or SOJ package. Its input and output levels are TTL compatible. The standby current is very low, typically a few microamps, making it suitable for applications requiring data retention with minimal power consumption.
