The AT28HC64B-70SC is a 64K (8K x 8) Parallel EEPROM manufactured by Atmel. It's known for its high performance, low power consumption, and reliable data storage. Being an EEPROM (Electrically Erasable Programmable Read-Only Memory), it allows for in-system electrical erasure and reprogramming, providing flexibility in applications requiring non-volatile memory that can be updated.

Applications

• Embedded systems for storing configuration data
• Industrial control systems
• Data loggers
• Consumer electronics, such as set-top boxes and personal computers
• Program storage for microcontrollers

Features

• Fast Access Time: 70 ns read access time for quick data retrieval.
• Low Power Consumption: Active current of 40 mA and standby current of 100 μA.
• High Endurance: 10,000 write cycles endurance rating.
• Data Retention: Guaranteed data retention for 10 years.
• Page Write Operation: Allows writing up to 64 bytes simultaneously, reducing write time.
• Self-Timed Write Cycle: Simplifies the write process.
• JEDEC Standard Pinout: Ensures compatibility with other memory devices.
• TTL Compatibility: Fully TTL compatible I/O.
