Universal LCD driver for low multiplex rates
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
The PCF8534A is a peripheral device which interfaces to almost any Liquid Crystal Display (LCD) with low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 60 segments. It can be easily cascaded for larger LCD applications. The PCF8534A is compatible with most microcontrollers and communicates via the two-line bidirectional I²C-bus. Communication overheads are minimized by a display RAM with auto-incremented addressing, by hardware subaddressing, and by display memory switching (static and duplex drive modes).
PCF8534AHL should not be used for new designs. Recommended replacement: PCF85134HL
