256 x 72 x 4-bit OLED passive matrix controller/driver

Data Brief

Features

Description

■ Supports monochrome, passive-matrix OLED

The STV8105 is a low-power, controller/driver

“combo” IC for OLED displays. The STV8105

supports 256 columns by 72 rows with 16 levels

of gray for monochrome and 2 x 128 columns by

72 rows with 16 levels of gray for “two” color

displays. It can control a display of 128 columns

by 72 rows or 256 columns by 36 rows with 64

levels of gray in monochrome mode.

displays in different formats:

– 256 x 72 black & white

– 256 x 72 x 2-bits /4 levels of gray

– 256 x 72 x 4-bits /16 levels of gray

– 256 x 36 x 6-bits / 64 levels of gray

– 128 x 72 x 6-bits / 64 levels of gray

■ On-chip DC/DC step-up converter

■ Display power supply up to 25 V

■ Device power supply: 3.0 to 3.6 V

The STV8105 provides all necessary functions in

a single chip, including on-chip supply control and

bias current generators, resulting in a minimum of

external components and in very low-power

consumption.

■ Low-power consumption suitable for battery-

operated systems

The STV8105 communicates with the system via

fully configurable interfaces (parallel or serial) to

ease interfacing with the host microcontroller. The

STV8105 has a set of command and control

registers that can be addressed by these

interfaces.

■ Column source current capability: 800 µA,

max.

■ Row sink current capability: 110 mA, max.

■ On-chip oscillator

■ Programmable gamma correction

■ Programmable display multiplexing

■ Two brightness control registers of 128 steps

each

■ 32 steps dimmer control

■ One time programmable (OTP) fuse ROM for

key configuration parameters

■ Dual scan, master/slave capability

■ Selectable 8-bit parallel as well as serial

peripheral interfaces
