NXP USA Inc. PCA8576FUG/2DA/QKP

Description
The PCA8576F is a peripheral device that interfaces with low multiplex rate Liquid Crystal Displays (LCDs). It generates drive signals for static or multiplexed LCDs with up to four backplanes and 40 segments. The device can be cascaded for larger LCD applications. The PCA8576F is compatible with most microcontrollers and communicates via the two-line bidirectional I2C-bus.
