The PCF8582C-2T is a 256 x 8-bit static Random Access Memory (RAM) with a serial I2C-bus interface. While originally manufactured by Philips Semiconductors (now NXP), Integrated Circuit Systems (ICS) may have been a second-source or distributor. This device is designed for applications requiring non-volatile data storage with a simple two-wire serial interface.

Applications:

• Data logging
• Configuration storage
• Parameter storage
• Electronic metering
• Industrial control systems

Features:

• 256 x 8-bit (256 bytes) of static RAM
• I2C-bus serial interface
• Low standby current
• Single supply voltage
• Write protect feature

Benefits:

• Compact non-volatile storage.
• Simple integration into microcontroller-based systems using the two-wire I2C interface.
• Minimized power consumption in battery-powered applications due to the low standby current.
• Easy to use with a single supply voltage requirement.
• Data integrity protection against accidental writes.

Additional Details:

Technical Specifications:

• Operating Voltage: 2.5V to 5.5V
• I2C Bus Speed: Up to 100 kHz
• Standby Current: Typically less than 10 uA
• Operating Temperature: -40°C to +85°C
• Package: SO8 or DIP8

The PCF8582C-2T provides a convenient and cost-effective solution for adding non-volatile data storage to embedded systems with I2C interfaces. Its low power consumption and simple interface make it suitable for a variety of applications.
