MOS INTEGRATED CIRCUIT
µPD16667
160-OUTPUT LCD ROW DRIVER
The µPD16667 is a row (common) driver which contains a RAM capable of full-dot LCD display. With 160 outputs,
this driver can be combined with a column (segment) driver, µPD16662, which contains a RAM to display 240 × 160
pixels to 480 × 320 pixels.
With a built-in display RAM, the column driver can reduce the current consumption, thus making it most suitable
for the display block of a PDA or portable terminal.
FEATURES
• LCD-driven voltage: 20 to 36 V
• Duty: 1/160
• Driving type: 2 lines selected simultaneously
• Output count: 160 outputs
• Capable of gray scale display: 4 gray scales

Liquid-crystal drive output
Selects and outputs one of VDD, VEE, and V1.
DETAILS OF PIN FUNCTIONS
• STB (input)
Input pin of the row drive strobe signal
The bidirectional shift register is shifted at STB’s rising edge.
• /FRM (input)
Input pin of the frame signal
The shift register data is read at STB’s rising edge.
• DIR (input)
Input pin of the drive output’s shift direction selection signal
When the shift direction selection signal (DIR) is “L”, the shift data (selection signal) is shifted from the drive
output X1 to the X160 direction. When “H”, it is shifted from the X160 to the X1 direction.
• /DOFF(input)
Input pin of the display OFF signal
It is placed in the display OFF status (all outputs at V1) at the “L” level. In the mean time, it reads the frame signal
and returns to the normal display status at the “H” level.
• L1 and L2 (input)
Input pins of the drive level power selection signal
In the case of the liquid-crystal drive output, the two lines are selected simultaneously by the shift register. L1
selects the first line, and L2 selects the second line. Both lines select VDD at “H”, and VEE at “L”.
