STV8116
162 RGB x 132 single chip true 262K color OLED controller/driver
Data Brief
Features

Description
The STV8116 is a low-power CMOS controller/driver "combo" IC for passive OLED displays featuring extremely low current consumption. Designed to drive displays of up to 132 rows by 162 columns with 262K colors, the STV8116 provides all necessary functions in a single chip, including an on-chip DC/DC step-up converter resulting in a minimum of externals components. This IC provides automatic precharge and Vrowoff voltages as well as self adjustment of the Vpp voltage. Global power management is automatically adjusted to changes in brightness levels, aging of the display and temperature. Embedded OTP memory allows various adjustments and storages such as white balance, gamma table and frame frequency. These features contribute to enhanced picture quality, low power dissipation, improved robustness and reduced manufacturing cost. A complete set of digital functions reduces host microcontroller overhead to manage complex display configurations and fast moving image data transfers to the display RAM of the STV8116. STV8116 features five standard I/O interfaces (3wire serial, 3-wire SPI, 4-wire SPI, 68000 parallel and 8080 parallel) for easy interfacing with the host microcontroller.
