Automotive Digital Clock

PT6398

DESCRIPTION

PT6398 is an automotive digital clock CMOS LSI. It drives fluorescent indicator panel directly. It can be

driven by a 4.194304MHz crystal oscillator or an external clock signal (1024Hz). It has 4-ways display

brightness control function and its display format is 12 hours.

FEATURES

• 4.194304MHz crystal oscillator

• 4-ways display brightness control

(Segment duty for Static: 1, 1/4, 1/8, 1/16; Grid duty for dynamic: 6.25%, 12.5%, 25%, 50%)

• Hour and Minutes setting

• ±30 Minutes auto correction

• 1024Hz signal output

• Segment output: CMOS output

• Internal POR (Power on Reset Circuit)

• 44 pin LQFP

• Static and dynamic driving selected
