93LC76 Datasheet (Microchip Technology) - 8K/16K 2.5V Microwire Serial EEPROM

93LC76, 8K/16K 2.5V Microwire Serial EEPROM

The PCA9531 is an 8-bit I2C & SMBus I/O expander optimized for dimming LEDs in 256 discrete steps for Red/Green/Blue (RGB) color mixing and back light applications.

The PCA9531 contains an internal oscillator with two user programmable blink rates and duty cycles coupled to the output PWM.
