SAA1064T/N2,118

Overview

The SAA1064T/N2,118 is a four-channel LED driver integrated circuit manufactured by NXP. It features an I2C-bus interface for serial data communication, allowing control of up to sixteen LEDs through multiplexing or direct drive modes. The device includes internal registers for brightness control and display configuration. It operates with a supply voltage range typically between 2.5V and 5.5V. The output stage supports sink currents suitable for common cathode LED arrays. The component is housed in a small outline package designed for surface mount applications.

Feature Summary

• Integrates an I2C-bus interface for simplified serial control connections
• Provides independent brightness control for multiple LED channels
• Supports flexible display configurations including multiplexed driving

Applications

• LED display panels requiring low pin count control
• Consumer electronics with status indicator arrays
• Instrumentation front panels with segmented displays

Procurement Notes

Verify the specific suffix 'N2,118' against official NXP documentation to confirm tape and reel packaging details and temperature grade. Ensure compatibility with your system's I2C bus voltage levels before integration. Cross-reference the full part number with authorized distributors to avoid counterfeit components. Confirm that the required current sinking capability matches your LED specifications.

Selection Notes

Select this component when a compact solution for controlling multiple LEDs via a standard two-wire interface is required. It is suitable for designs where microcontroller GPIO pins are limited. Consider the maximum sink current per channel and the total power dissipation limits relative to your thermal design. Evaluate the operating voltage range against your system's power supply rails.

Part Context

This part belongs to the SAA1064 family of LED drivers. These devices are designed for simple, cost-effective LED control in embedded systems. The family offers variations in packaging and temperature ranges. The SAA1064 specifically targets applications needing basic multiplexing capabilities without complex external logic.

Replacement Considerations

Check for direct replacements within the SAA1064 series from NXP. Verify pinout compatibility if substituting with similar I2C LED drivers from other manufacturers. Ensure functional equivalence in terms of current sourcing/sinking capabilities and register mapping.
