GENERAL DESCRIPTION
ST7565P is a single-chip dot-matrix LCD driver that can be connected directly to a microprocessor bus. 8-bit parallel or serial display data sent from the microprocessor isstored in the internal Display Data RAM and this chip generates LCD driving  signals  independent  of  the  microprocessor.

FEATURES
Directly display RAM data through Display Data RAM
RAM capacity : 65 x 132 = 8580 bits
Display duty selectable by select pin
  1/65 duty : 65 common x 132 segment
  1/49 duty : 49 common x 132 segment
  1/33 duty : 33 common x 132 segment
  1/55 duty : 55 common x 132 segment
  1/53 duty : 53 common x 132 segment
High-speed 8-bit MPU interface:
  ST7565P can be connected directly to both the 80x86
  series MPUs and the 6800 series MPUs.
  Serial interface (SPI-4) is also supported.
Abundant command functions:
  Display data read/write, display ON/OFF, Normal/Reverse display mode, page address set, display start line set, column address set, status read, display all points ON, LCD bias set, electronic volume, read-modify-write, set segment driver direction, power save mode, set common output direction, set V0 regulator internal resistor ratio.
Built-in low power consumption power circuits:
  Booster, Regulator and Follower.
