6max • 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 228 segments using 1/3 duty and up to 300 segments using 1/4 duty.
• Sleep mode and all segments off functions that are controlled from serial data.
• Segment output port/general-purpose output port function switching that is controlled from 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 VLCD for the LCD driver block (VLCD can be set to in the range VDD – 0.
5 to 6.
0 volts.
) • Provision of an on-chip voltage-detection type reset circuit prevents incorrect displays.
• RES pin provided for forcibly initializing the IC internal circuits.
• RC oscillator circuit.
• CCB is a trademark of SANYO ELECTRIC CO.
, LTD.
• CCB is SANYO’s original bus format and all the bus addresses are controlled by SANYO.
