Description

General Description 1.The AW86066 is an optical image stabilization (OIS) controller and driver which also support auto focus driving. It is always used in a camera module of smart mobile phone or other camera equipment. 2.The STARCU is Harvard structure and has own DSP and FPU. The bus for code connects flash, ROM and code SRAM and the bus for data connects data SRAM and APB bridge. With the 48MHz clock, STARCU can provide 72DMIPS computing power for algorithm. 3.The AW86066 integrates an on-chip 32-bit CPU as the controller, a flash memory for program and user data, 3 channels per ADC, 2 DACs for calibrating Hall sensor offsets, 2 Hall bias circuits, and 3 H-bridge drivers for OIS and AF. 4.The AW86066 DSP has dedicated ALU hardware that integrates instruction flow control, storage access, scalar operations, matrix operations, and digital filters, specifically designed for algorithm acceleration optimization. 5.There is an SPI I/F module that supports on-chip master, slave, and monitor. One I2C module is available, supporting master/slave mode, and one I3C module supports master/slave mode.
