STV8116 162 RGB x 132 single chip true 262K color OLED controller/driver Data Brief Features Description ■ 162x132 display matrix ■ 200µA max column current ■ 100mA max row current The STV8116 is a low-power CMOS controller/driver “combo” IC for passive OLED displays featuring extremely low current consumption. ■ On-chip DC/DC step-up converter supplied from a 2.3 to 6V battery ■ Low power optimization: – automatic precharge voltage – Vrowoff optimization voltage – Vpp self adjustment ■ 262Kcolor mode among 2M color Palette (24bit look-up table for gamma settings) ■ Dual partial display modes ■ Vertical scrolling ■ Programmable number of lines ■ Programmable frame rate, 165Hz max. ■ Selectable input interfaces (read and write), operating voltage compatible with 1.8V as well as 3.3V signals: – 68000 and 8080 parallel interfaces – 3-wire and 4-wire SPI interfaces – 3-wire, 9-bit serial interface ■ Fully integrated oscillator requires no external components ■ 7-bit RGB brightness control ■ 5-bit luminance control ■ Low-voltage digital supply range: 1.65 to 1.95V ■ Low-voltage analog supply range: 2.2 to 3.6V ■ 3.3V single supply with on-chip 1.8V LDO ■ High-voltage display supply range: 4.5 to 22V ■ One Time Programmable (OTP) non-volatile embedded memory ■ Delivered in bumped die for chip-on-glass (COG) or chip-on-foil (COF). December 2006 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.
