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.
? AD converter :12bit / Input 4ch / Equipped with a sample-hold circuit
? DA converter :8bit / Output 3ch
? Built-in 2-wire Serial I/F circuit (with clock stretch function)
