The NXP SAA1064 is a highly integrated LED-driver designed for managing up to four 7-segment numeric displays. This robust and versatile component is optimized for use with I2C-bus interfaces, which makes it an ideal choice for a wide range of applications that require clear and bright numeric displays.

Key Features

        
• I2C-Bus Interface: The SAA1064 features a two-wire I2C-bus interface that supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes, providing easy integration with microcontrollers and other I2C-compatible devices.
        
• Drive Capability: It can control up to four digits with 7 segments and decimal points, or 28 segments/elements in a multiplexed layout, delivering consistent brightness through constant current sources.
        
• Programmable Current: Each segment's current can be programmed from 3 mA to 21 mA in 3 mA steps, allowing for brightness control and power saving.
        
• Digit Multiplexing: The device supports 1 to 4 multiplexed common anode LED digits, providing flexibility in display design.
        
• Integrated Multiplex Drive Circuitry: This includes a 4-bit latch and decoder per segment, and a 4-bit latch for each common output, reducing the need for additional components.
        
• Blanking Control: Users can blank all segments or display a "light test" mode via software control.
    

Applications

The SAA1064 is suitable for a wide range of applications, including but not limited to:
