STV8115
132 RGB x 162 single chip true 262K color OLED controller/driver
Data Brief

Features

Description
The STV8115 is a low-power CMOS controller/driver "combo" IC for passive, small screen, OLED displays.The STV8115 features extremely low current consumption. Designed to drive displays of up to 162 rows by 396 (132 RGB) columns with 262K colors, the STV8115 provides all necessary functions in a single chip, including an on-chip DC/DC step-up converter resulting in a minimum of externals components.

132RGB x 162 display matrix 200uA max column current 100mA max row current 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 16 Million color Palette (24-bit 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: 2.3 to 3.6V 3.3V single supply with on-chip 1.8V LDO High-voltage display supply range: 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).

Note. For small screen, OLED display applications of up to 132 rows by 486 (162 RGB) columns, see the datasheet for the STV8116.
The STV8115 provides automatic precharge and Vrowoff voltages as well as self adjustment of Vpp. 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 STV8115. STV8115 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.
