6. LCD (ST Micro ST7066) display with LVCMOS25 inputs. This dual row 16 character per row uses an
industry standard controller (Samsung KS0066U) and sports a 4 or 8 bit data interface. No backlight is
provided for the LCD, and the contrast if fixed.
This LCD supports 5x8 and 5x10 dot matrix characters and a programmable 4 or 8 bit MPU interface.
Support for custom characters is provided as is a wide range of instruction functions such as clear,
cursor home, display on/off, cursor shift, and display shift.
Signal Name Pin Voltage Description
LCD Data 0 G22 2.5V Four low order bi-directional
tristate data bus pins. Used for
data transfer and receive
between the MPU and the
ST7066.
These pins are not used during
4-bit operation.
LCD Data 1 H22 2.5V As above
LCD Data 2 H23 2.5V As above
