PCF8562TT/2,518

Display Drivers Overview

The PCF8562TT/2,518 is a CMOS peripheral device designed to interface with Liquid Crystal Displays (LCDs) featuring low multiplex rates. It generates drive signals for static or multiplexed LCDs containing up to four backplanes and 32 segments. The component communicates via a two-line bidirectional I²C-bus, minimizing communication overhead through display RAM with auto-incremental addressing and hardware subaddressing. It supports selectable backplane configurations (static, 2, 3, or 4 backplanes) and display bias settings (static, 1/2, or 1/3). The device operates within a wide power supply range of 1.8 V to 5.5 V and features internal LCD bias generation with voltage-follower buffers.

Display Drivers Procurement Notes

Verify the specific ordering suffix matches the required package type and tape-and-reel quantity specifications. Confirm that the I²C address and register map align with the host microcontroller implementation. Ensure the operating voltage range of the target system falls within the specified limits for both logic and LCD supplies. Check for any regional compliance certifications required for the final product integration.

Display Drivers Selection Notes

Select this component when driving LCDs with up to 32 segments and four backplanes. It is suitable for designs requiring low communication overhead and flexible bias configurations. Consider alternatives if higher segment counts or different interface protocols are needed. Verify compatibility with the intended microprocessor architecture and ensure the power supply constraints meet the device's operational requirements.
