MOS INTEGRATED CIRCUIT
µ PD16664
144/160/184/208-OUTPUT LCD COLUMN (SEGMENT) DRIVER WITH RAM
DESCRIPTION
The µ PD16664 is a column (segment) driver with internal RAM and can drive a full-dot LCD. Equipped with
144/160/184/208-output pins and a display RAM of 208 x 160 x 2 bits, this driver can display any of four gray levels
selected from a 25-level palette. By using this IC in combination with the µ PD16667, 144 x 128 pixels to 416 x 320
pixels can be displayed.
FEATURES
• Internal display RAM : 208 x 160 x 2 bits
• Logic voltage
: 2.4 to 3.6 V
• Duty
: 1/128, 1/160 selectable
• Number of outputs : 144,160,184 and 208 pins selectable
• Display
: Four gray levels (selectable from 25-level palette)
• Memory management : Packed pixel method
• Supports 8/16-bit data bus

µ PD16664
(9) Gray level control
This circuit implements the 4-gray level display.
(10) Data latch (1)
This circuit reads data for 208 pixels from RAM and latches it.
(11) Data latch (2)
This circuit latches data for 208 pixels in synchronization with the STB signal.
(12) Level shifter
The level shifter converts the operating voltage of the internal circuit(VCC2) into the voltage for the liquid crystal
driver circuit and row driver interface (VCC1).
(13) DEC
This is a decoder that decodes gray level display data to liquid crystal drive voltages V0, V1, or V2.
(14) Liquid crystal drive circuit
This circuit selects liquid crystal drive voltage V0, V1, or V2 corresponding to gray level display data and the
display OFF signal (/DOFF), to generate a liquid crystal application voltage.
(15) Self-diagnosis circuit
If the operation timing of the master chip and that of the slave chip differ due to external noise, this circuit
automatically detects the difference and generates a refresh signal to all column drivers.
