L9213 - Brand New Oki Semiconductor IC Chips
-
GENERAL DESCRIPTION
The ML9213 is a full CMOS controller/driver for Duplex or Triplex (1/2 duty or 1/3 duty) vacuum fluorescent display tube. It consists of a 56-segment driver multiplexed to drive up to 168 segments, and 10-bit digital dimming circuit.
FEATURES
• Logic supply voltage (VDD) : 5.0 V 10%
• Driver supply voltage (VDISP) : 8.0 to 18.0 V
• Duplex/Triplex (1/2 duty / 1/3 duty) selectable
DUP/TRI = 1/2 duty selectable at “H” level
DUP/TRI = 1/3 duty selectable at “L” level
• Number of display segments
112 segments max. (during 1/2 duty mode)
168 segments max. (during 1/3 duty mode)
• Master/Slave selectable
M/S = “H” level : Master mode
M/S = “L” level : Slave mode
• Interface with a microcontroller
Three lines: CS, CLOCK, and DATA IN
• 56-segment driver outputs : IOH = –5.0 mA at VOH = VDISP–0.8 V (SEG1 to 37)
(can be directly connected to VFD tube : IOH = –10.0 mA at VOH = VDISP–0.8 V (SEG38 to 56)
and requires no external resistors) : IOL = 500 μA at VOL = 2.0 V (SEG1 to 56)
• 3-grid pre-driver outputs : IOH = –5.0 mA at VOH = VDISP–0.8 V
(requires external drivers) IOL = 10.0 mA at VOL = 2.0 V
• Logic outputs : IOH = –200 μA at VOH = VDD–0.8 V
IOL = 200 μA at VOL = 0.8 V
• Built-in anode digital dimming circuit (10-bit resolution)
• Built-in oscillation circuit (external resistor and capacitor)
• Built-in Power-On-Reset circuit
