ML9092-01/02/03/04
LCD Driver with Key Scanner and RAM
FEDL9092-01
Issue Date: Nov. 4, 2003
GENERAL DESCRIPTION
The ML9092-01/02/03/04 are LCD drivers that have internal RAM and a key scan function. They are best suited
for car audio displays.
Since 1-bit data of the display data RAM corresponds to the light-on or light-off of 1-dot of the LCD panel (a bit
map system), a flexible display is possible.
A graphic display system of a maximum of 60
×
10 dots (56
×
10 dots for ML9092-01, 60
×
10 dots for
ML9092-02/03/04). can be implemented.
The ML9092-01/02 do not require any power supply circuit to drive the LCD, because they have internal voltage
doublers. (If a large-sized panel is driven, use the ML9092-03, to which the LCD driving voltage is supplied
externally.)
The internal key scan circuit (5
×
5 key scanning for ML9092-01/04, 6
×
4 key scanning for ML9092-02/03) has
eliminated the needs of key scanning by the CPU, thereby enabling the efficient use of the CPU ports.
FEATURES
Logic voltage
: 4.5 to 5.5 V
LCD drive voltage
: 4.5 to 16.5 V (positive voltage)
Segment output
: 56 outputs for ML9092-01; 60 outputs for ML9092-02/03/04
Common output
: 10 outputs
Built-in bit-mapped RAM
: 60
×
10 = 600 bits (for ML9092-01 only: 56
×
10 = 560 bits for the RAM
display area)
4-pin serial interface with CPU:
CS
,
CP
, DI/O, KREQ
Built-in LCD drive bias resistors
Built-in voltage doubler circuit
For the ML9092-01/04, the built-in 5
×
5 key scanner makes it possible to read the status of 25 key switches and
1-channel rotary encoder. In addition, the ML9092-01/04 have an 8-bit, 3-channlel PWM circuit built in.
For the ML9092-02/03, the built-in 6
×
4 key scanner makes it possible to read the status of 24 key switches and
1-channel rotary encoder.
