STV8102 128 x 64 OLED passive matrix controller/driver Data Brief Features Description ■ Supports 128 x 64 dot matrix panels ■ Embedded DC/DC step-up converter ■ Display power supply up to 20V ■ Device power supply: 1.8 to 3.6V The STV8102 is a low-power, controller/driver “combo” IC for Organic Light Emitting Diode (OLED) dot passive matrix display systems.The STV8102 supports black-an-white, monochrome displays of up to 128 columns by 64 rows. ■ Low-power consumption suitable for batteryoperated systems ■ Column source current: 508µA, max ■ Row sink current: 64mA ■ On-chip oscillator ■ Programmable multiplexing rate ■ Self adaptive panel addressing scheme ■ PowerMizer™ driving scheme ■ Brightness control with built-in aging compensation ■ Built-in display pattern generator ■ Selectable 8-bit parallel interface (68xx, 80xx series), serial peripheral interface and I²C interface ■ Embedded 128 x 64 x 1-bit display RAM ■ Row and column re-mapping ■ Screen saver mode January 2007 The STV8102 provides all necessary functions in a single chip, including on-chip OLED supply control and bias current generators resulting in a minimum of external components and in very lowpower consumption. The STV8102 communicates with the system via fully configurable interfaces (parallel, serial or I2C) to ease interfacing with the host microcontroller. The STV8102 has a set of control and status registers that can be addressed by the interfaces.
