µPD16663
240-OUTPUT LCD COLUMN (SEGMENT) DRIVER WITH BUILT-IN RAM
DESCRIPTION
The µPD16663 is a column (segment) driver device with built-in RAM. It is capable of driving a full-dot LCD.
There are 240 outputs that, with the 240 × 160 × 4-bit built-in display RAM, enable a 16-gray scale display. The
sixteen gray scales can be selected arbitrarily from a 49-stage palette. When combined with the µPD16667, this
device can drive displays of 240 × 160 to 480 × 320 dots.
FEATURES
• Built-in display RAM: 240 × 160 × 4 bits
• Logic voltage: 3.0 to 3.6 V
• Duty cycle: 1/160
• Number of outputs: 240
• Gray scales: 16 (selectable from a palette of 49)
• Memory management: Packed pixel
• Compatible with 8-bit/16-bit data buses

µPD16663
(10) Data latch (1)
Latches 240-pixel data read from RAM.
(11) Data latch (2)
Latches 240-pixel data in synchronization with the STB signal.
(12) Level shifter
Converts the internal circuit operating voltage (3.3 V) to the voltage required by the LCD driver and row
driver interface (5 V).
(13) DEC
Decodes the gray scale display data into the corresponding LCD drive voltages V0, V1, and V2.
(14) LCD driver circuit
Creates the voltage to be applied to the LCD by selecting one of LCD drive power supplies V0, V1, or V2,
according to the gray scale data and display off signal (/DOFF).
(15) Self-diagnostic circuit
Automatically detects any mismatch between the operation timings of the master and slave chips cause by
noise, etc., and issues a refresh signal to all the column drivers.
