FEATURES

● Key input function for up to 30 keys (A key scan is performed only when a key is pressed.)

● 1/3 duty and 1/4 duty drive schemes can be controlled from serial data.

● 1/2 bias and 1/3 bias drive schemes can be controlled from serial data.

● Capable of driving up to 126 segments using 1/3 duty and up to 164 segments using 1/4 duty.

● Sleep mode and all segments off functions that are controlled from serial data.

● Switching between key scan output and segment output can be controlled from the serial data.

● The key scan operation enabled/disabled state can be controlled from the serial data.

● Switching between segment output port and general-purpose output port can be controlled from serial data.

● The common and segment output waveform frame frequency can be controlled from the serial data.

● Switching between RC oscillator mode and external clock mode can be controlled from the serial data.

● Serial data I/O supports CCB format communication with the system controller.

● Direct display of display data without the use of a decoder provides high generality.

● Independent V_LCD for the LCD driver block.

(When the logic block supply voltage V_DD is in the range 3.6 to 6.0V, V_LCD can be set to a voltage in the range 0.75 x V_DD to 6.0V, and when V_DD is in the range 2.7 to 3.6V, V_LCD can be set to a voltage in the range 2.7 to 6.0V.）

● Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.

● AEC-Q100 Grade2 Compliant for Automotive Applications

● Package - LQFP64
