The MB81C84A-35P-G is a static random-access memory (SRAM) chip manufactured by Fujitsu Electronics America, Inc. It is a type of semiconductor memory that retains data as long as power is supplied, unlike dynamic RAM (DRAM) which requires periodic refreshing. The “-35” in the part number likely refers to its access time (35ns), which is a critical parameter for memory speed. The “P” typically indicates a plastic package, and the “G” could signify a specific grade or revision.

Applications:

• Cache memory in computer systems
• Embedded systems requiring fast memory access
• Data storage in industrial control equipment
• Networking equipment (routers, switches)
• Telecommunications systems

Features:

• Fast access time (35ns)
• Static RAM – no refresh required
• Low power consumption (compared to DRAM)
• TTL compatible inputs and outputs
• Plastic DIP package

Benefits:

• High-speed data access
• Simplified memory system design (no refresh circuitry needed)
• Suitable for battery-backed applications due to low power
• Easy integration with standard logic circuits
• Cost-effective solution for moderate memory requirements

Additional Details:

The MB81C84A-35P-G is typically organized as a certain number of bits by a certain number of words (e.g., 64K x 1 bit, 8K x 8 bits). The specific organization dictates how data is addressed and accessed within the memory chip. The chip operates on a standard supply voltage (e.g., 5V). The plastic DIP (Dual In-line Package) allows for easy insertion into sockets or soldering onto printed circuit boards. Detailed electrical characteristics, such as operating current, standby current, and input/output voltage levels, are specified in the Fujitsu datasheet. It's crucial to consult the datasheet for precise specifications and application guidelines to ensure proper operation and avoid damage to the device.
