LC898123AXD数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

LC898123AXD is a system LSI integrating an on-chip 32bit DSP, a Flash Memory and peripherals including analog circuits for Optical Image Stabilization (OIS) / Auto Focus (AF) control and H-bridge and constant current drivers.

特性 Features

• On-chip 32-bit DSPBuilt-in software digital servo filterBuilt-in software Gyro filter
• The onchip DSP allows the Optical Image Stabilization (OIS) algorithm to be flexible and achieve the high Optical Image Stabilization (OIS) performance.
• Flash Memory :12k Byte Flash memory to store data and DSP program
• The Onchip Flash allows to store the calibration data and DSP program. No external NVM is necessary for this.
