• Manufacturer Part Number: SAK-C505L
• Description: 8-bit CMOS Microcontroller
• Manufacturer: Infineon Technologies AG

Display Voltage Levels
The LCD controller outputs three voltage levels required for driving the LCD display module. These
voltage levels are generated by a programmable 8-bit D/A converter via the register DAC0 and a
resistive divider network. The D/A converter is enabled by the LCD controller enable bit LCEN
(LCON.0). Any write operation to the register DAC0 with the LCD controller enabled, starts the D/A
conversion and thereby the display outputs. Therefore, the C505L can be used with a wide range
of LCD display modules.
LCD Controller in Power Saving Mode
In order to reduce power consumption, the C505L can be put into the software power down mode 2.
In this mode, the LCD controller and the D/A converter do not lose their register contents and remain
in operation, provided the following conditions are satisfied:
Data Sheet
– The input clock to the LCD is the 32.768 kHz real-time clock input, and
– The real-time clock input at XTAL3 and XTAL4 pins is still valid.
