Overview
The PCF8577CT/3,118 is an LCD driver IC manufactured by NXP USA Inc., designed for segment-based displays. It operates on a supply voltage range of 2.5V to 6V and supports an operating temperature from -40°C to 85°C. The device features a 40-BSOP (40-VSO) surface-mount package and communicates via an I2C interface. It is configured as a 32-segment driver. This specific part number is identified as obsolete or end-of-life.
Feature Summary
- Functions as a dedicated LCD driver with 32-segment configuration capability.
- Utilizes an I2C bus interface for communication with microcontrollers.
- Supports surface mount installation in a compact 40-pin BSOP/VSO package.
Applications
- Segmented LCD display modules
- Industrial instrumentation panels
- Consumer electronic devices requiring simple LCD interfaces
Procurement Notes
This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking distributor stock levels for remaining inventory. Designers should consider alternative components or lifecycle management strategies due to the discontinuation status. Confirm RoHS compliance and specific revision details through official datasheets before procurement.
Selection Notes
Select this component only if legacy compatibility with existing 32-segment LCD designs is required. Ensure the system design accommodates the 40-BSOP package footprint. Verify that the I2C address configuration meets system requirements. Consider the limited future supply chain support when planning long-term production runs.
Part Context
The PCF8577 series belongs to NXP's family of low-power CMOS LCD drivers. These devices are typically used in conjunction with row drivers like the PCF8578 to form complete dot-matrix display solutions. The CT suffix indicates a specific tape-and-reel packaging variant within the broader PCF8577 product line.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements may require verification against newer NXP LCD driver models such as the PCF8579 or PCF8551 families, depending on segment count and interface needs.
