The SEEQ PQ28C64-200 is a 64K (65,536 bits) EEPROM (Electrically Erasable Programmable Read-Only Memory) chip. It's a non-volatile memory, meaning it retains its data even when power is removed. The "-200" likely indicates an access time of 200 nanoseconds.

Applications:

• Storing configuration data in embedded systems
• Storing calibration data in instruments
• Storing serial numbers and identification information
• Firmware storage for microcontrollers
• Data logging applications
• Replacing DIP switches or jumpers for setting options

Features:

• 64Kbit (8K x 8) capacity
• Electrically erasable and programmable
• Non-volatile data storage
• Fast access time (200ns)
• Low power consumption
• TTL compatible inputs and outputs
• Industry-standard pinout

Benefits:

• Ability to update data in-system without removing the chip
• Reliable data storage even without power
• Fast read access for quick retrieval of data
• Easy integration into existing systems
• Reduced board space compared to other memory solutions

Technical Specifications:

The PQ28C64-200 has a capacity of 64 kilobits, organized as 8192 bytes (8K x 8). The access time is 200 nanoseconds, allowing for relatively fast read operations. It operates on a standard 5V power supply and features TTL-compatible inputs and outputs. It's electrically erasable and programmable, allowing data to be changed in-system without requiring ultraviolet light or other external equipment. Consult the SEEQ datasheet for detailed specifications, timing diagrams, and programming algorithms.

The SEEQ PQ28C64-200 is a reliable and versatile EEPROM chip suitable for a wide range of applications where non-volatile data storage is required. Its in-system programmability and fast access time make it a valuable component in many embedded systems.
