Display Drivers datasheet and documents for PCF8551ATT/AJ
Display Drivers Overview
The PCF8551ATT/AJ is a universal LCD segment driver manufactured by NXP Semiconductors. It supports up to 36 segments, enabling configurations for 18 seven-segment digits, nine alphanumeric characters, or 144 graphic pixels. The device features an SPI bus interface with a maximum clock frequency of 3MHz. It operates on a single power supply voltage ranging from 1.8V to 5.5V and includes internal LCD bias voltage generation. The component is housed in a 48-TSSOP package.
Display Drivers Feature Summary
- Supports flexible display configurations including static, multiplexed backplanes, and various bias voltages
- Integrates internal LCD bias voltage generation with buffering capabilities
- Features automatic incrementing display data and instruction loading
- Offers multiple independent display blinking modes
Display Drivers Applications
- Universal LCD segment driver implementations
- Seven-segment numeric displays
- Alphanumeric character displays
- Graphic pixel matrix displays
Display Drivers Procurement Notes
Verify the specific suffix AJ against current NXP documentation to confirm package orientation and tape-and-reel specifications. Confirm RoHS compliance status through official environmental declarations. Check for active product longevity program participation to ensure long-term supply stability for embedded designs.
Display Drivers Selection Notes
Select this component when an SPI interface is required for LCD control instead of I2C. Ensure the design utilizes a 48-lead TSSOP footprint. Verify that the system power supply falls within the 1.8V to 5.5V range compatible with both VDD and VLCD pins.
Display Drivers Part Context
This part belongs to the PCF8551 family of universal LCD drivers. It shares core functionality with variants like the PCF8551BTT/AY but differs in interface type and packaging. The ATT suffix typically denotes a specific reel-based surface-mount configuration within the broader product line.
Display Drivers Replacement Considerations
PCF8551BTT/AY is listed as a direct substitute.
