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.

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 (3-

wire serial, 3-wire SPI, 4-wire SPI, 68000 parallel

and 8080 parallel) for easy interfacing with the

host microcontroller.
